Abstract The German yellowjacket, Vespula germanica F., and common yellowjacket, Vespula vulgaris L. (Hymenoptera: Vespidae), are pests of significant economic, environmental, and medical importance in many countries. There is a need for the development and improvement of attractive baits that can be deployed in traps to capture and kill these wasps in areas where they are a problem. Yellowjackets are known to feed on fermenting fruit, but this resource is seldom considered as a bait due to its ephemeral nature and its potential attractiveness to nontarget species. We analyzed the headspace volatiles of dried fruit and fruit powder baits with and without Brewer’s yeast, Saccharomyces cerevisiae, using gas chromatography–mass spectrometry, and we field tested these baits for their attractiveness to yellowjackets in Argentina. The addition of yeast to dried fruit and fruit powder changed the volatile compositions, increasing the number of alcohols and acids and decreasing the number of aldehydes. Dried fruit and fruit powder baits on their own were hardly attractive to yellowjackets, but the addition of yeast improved their attractiveness by 9- to 50-fold and surpassed the attractiveness of a commercial heptyl butyrate-based wasp lure. We suggest that further research be done to test additional varieties and species of yeasts. A dried fruit or fruit powder bait in combination with yeast could become a useful tool in the management of yellowjackets. PMID:28922898

Abstract Wasps integrate the floral visitors’ community and they can constitute a representative portion of the pollinators. For this reason, it was aimed to know and to analyze the floral preference of the Vespidae species and to investigate the use of floral resources for these wasps. The collects were performed between 2001 and 2008 in different localities of Rio Grande do Sul state (Estrela Velha, Santa Cruz do Sul, São Francisco de Paula e Sinimbu between 08:00 at 17:00 hours, utilizing entomological nets to catch the flower-visiting wasps. The collected specimens were deposited at the Coleção Entomológica de Santa Cruz do Sul (CESC. 1.483 specimens were captured belonging to 73 wasp species, whose 78.9% were Polistinae (30 species and 21.1% Eumeninae (43 species, visiting the flowers of 33 plant species classified in 16 botanical families; the families with the larger number of plant species were Asteraceae (12, Fabaceae (4 and Apiaceae (3. The plant species with the largest number of wasps collected was Schinus terebinthifolius Raddi (616, followed by Eryngium pandanifolium L. (137 and Eryngium horridum Spreng (122. The analysis of the trophic niche overlap of 26 species with four or more visited plant species, showed an overlap equal or higher than 50% in six cases.

Resumo. O Parque Estadual da Serra do Papagaio é a maior Unidade de Conservação do sul de Minas Gerais, com áreas de Mata Atlântica, floresta de Araucária e Campos de Altitude. Apesar da importância biológica da área, muitos grupos animais não foram estudados, como as vespas sociais, insetos que pertencem à ordem Hymenoptera, família Vespidae, e que desempenham importante papel ecológico em diferentes ecossistemas. O estudo foi conduzido nessa Unidade de Conservação em altitudes entre 1600 a 2200 m, no período de julho de 2013 a abril de 2014, durante vinte dias de amostragem, utilizando busca ativa e armadilhas atrativas para registro das espécies. Foram amostradas 22 espécies de vespas sociais distribuídas em sete gêneros. Número menor em relação a outros estudos do estado, o que, provavelmente, foi ocasionado pela elevada altitude. Houve uma predominância de ninhos com invólucro protetor e a espécie mais frequente foi Polybia fastidiosuscula Saussure, o que pode ser explicado pela melhor regulação térmica obtida pelo invólucro. Outras duas espécies frequentes foram Mischocyttarus drewseni Saussure e Mischocyttarus rotundicolis (Cameron que possuem ninhos sem invólucro, porém essas espécies possuem coloração escura, assim como o substrato utilizado para nidificação e isso poderia reter melhor a radiação solar. Contudo outros fatores bióticos e abióticos podem estar envolvidos.

Full Text Available Considerable importance has been given to nest construction and larval food transport to the nest as a precondition for the eusociality of insects. Most adult hymenopterans feed on liquids, although bees and a few wasps may also feed on pollen. Carrion represents an additional source of protein for some species and they will scavenge for dead animals in the wild. This paper aims at analyzing Hymenoptera visitors on a pig carcass during the process of decomposition, in the summer of 2005 and the winter of 2006 in Brazil, and comparing the results with other studies in the Neotropical region. To our knowledge, this is the first study which described the occurence of Agelaia pallipes, Polybia paulista and Scaptotrigona depilis on decomposing carcasses in southeastern Brazil. It also raises the hypothesis of possible applications of Hymenoptera to achieve more precise PMI estimations, apart from other insects already known as having great importance in such estimates.Considerável importância tem sido dada às construções de ninhos e transporte de alimento larval para o ninho como uma pré-condição para a eusociabilidade dos insetos.

Hornets Have It: A Conserved Olfactory Subsystem for Social Recognition in Hymenoptera?

Directory of Open Access Journals (Sweden)

Antoine Couto

2017-06-01

Full Text Available Eusocial Hymenoptera colonies are characterized by the presence of altruistic individuals, which rear their siblings instead of their own offspring. In the course of evolution, such sterile castes are thought to have emerged through the process of kin selection, altruistic traits being transmitted to following generation if they benefit relatives. By allowing kinship recognition, the detection of cuticular hydrocarbons (CHCs might be instrumental for kin selection. In carpenter ants, a female-specific olfactory subsystem processes CHC information through antennal detection by basiconic sensilla. It is still unclear if other families of eusocial Hymenoptera use the same subsystem for sensing CHCs. Here, we examined the existence of such a subsystem in Vespidae (using the hornet Vespa velutina, a family in which eusociality emerged independently of ants. The antennae of both males and female hornets contain large basiconic sensilla. Sensory neurons from the large basiconic sensilla exclusively project to a conspicuous cluster of small glomeruli in the antennal lobe, with anatomical and immunoreactive features that are strikingly similar to those of the ant CHC-sensitive subsystem. Extracellular electrophysiological recordings further show that sensory neurons within hornet basiconic sensilla preferentially respond to CHCs. Although this subsystem is not female-specific in hornets, the observed similarities with the olfactory system of ants are striking. They suggest that the basiconic sensilla subsystem could be an ancestral trait, which may have played a key role in the advent of eusociality in these hymenopteran families by allowing kin recognition and the production of altruistic behaviors toward relatives.

Ves v 5 and Pol d 5, which constitute antigen 5, are recognized as the major, most potent allergens of family Vespidae. Several studies have reported the diagnostic sensitivity of the novel recombinant (r)Ves v 5 and rPol d 5 allergens in routine clinical laboratory settings by analyzing a group of Vespula and Polistes venom-allergic patients. In this study, we analyzed the sensitivity to venom specific (s)IgE by spiking with rVes v 5 and rPol d 5 in Japanese patients suspected of Hymenoptera venom allergy. Subjects were 41 patients who had experienced systemic reactions to hornet and/or paper wasp stings. Levels of serum sIgE against hornet and paper wasp venom by spiking with rVes v 5 and rPold d 5, respectively, as improvement testing, compared with hornet and paper wasp venom, as conventional testing, were measured by ImmunoCAP. Of the 41 patients, 33 (80.5%) were positive (≥0.35 UA/ml) for hornet and/or paper wasp venom in conventional sIgE testing. sIgE levels correlated significantly (P venom (R = 0.78) in improvement testing and conventional testing. To determine specificity, 20 volunteers who had never experienced a Hymenoptera sting were all negative for sIgE against these venoms in both improvement and conventional testing. Improved sensitivity was seen in 8 patients negative for sIgE against both venoms in conventional testing, while improvement testing revealed sIgE against hornet or paper wasp venom in 5 (total 38 (92.7%)) patients. The measurement of sIgE following spiking of rVes v 5 and rPol d 5 by conventional testing in Japanese subjects with sIgE against hornet and paper wasp venom, respectively, improved the sensitivity for detecting Hymenoptera venom allergy. Improvement testing for measuring sIgE levels against hornet and paper wasp venom has potential for serologically elucidating Hymenoptera allergy in Japan.

Single-locus complementary sex determination in the inbreeding wasp Euodynerus foraminatus Saussure (Hymenoptera: Vespidae).

Science.gov (United States)

Stahlhut, J K; Cowan, D P

2004-03-01

The Hymenoptera have arrhenotokous haplodiploidy in which males normally develop from unfertilized eggs and are haploid, while females develop from fertilized eggs and are diploid. Multiple sex determination systems are known to underlie haplodiploidy, and the best understood is single-locus complementary sex determination (sl-CSD) in which sex is determined at a single polymorphic locus. Individuals heterozygous at the sex locus develop as females; individuals that are hemizygous (haploid) or homozygous (diploid) at the sex locus develop as males. sl-CSD can be detected with inbreeding experiments that produce diploid males in predictable proportions as well as sex ratio shifts due to diploid male production. This sex determination system is considered incompatible with inbreeding because the ensuing increase in homozygosity increases the production of diploid males that are inviable or infertile, imposing a high cost on matings between close relatives. However, in the solitary hunting wasp Euodynerus foraminatus, a species suspected of having sl-CSD, inbreeding may be common due to a high incidence of sibling matings at natal nests. In laboratory crosses with E. foraminatus, we find that sex ratios and diploid male production (detected as microsatellite heterozygosity) are consistent with sl-CSD, but not with other sex determination systems. This is the first documented example of sl-CSD in a hymenopteran with an apparent natural history of inbreeding, and thus presents a paradox for our understanding of hymenopteran genetics.

Molecular cross-reactivity caused by allergen homology or cross-reactive carbohydrate determinants (CCDs) is a major challenge for diagnosis and immunotherapy of insect venom allergy. Venom phospholipases A1 (PLA1s) are classical, mostly non-glycosylated wasp and ant allergens that provide diagnostic benefit for differentiation of genuine sensitizations from cross-reactivity. As CCD-free molecules, venom PLA1s are not causative for CCD-based cross-reactivity. Little is known however about the protein-based cross-reactivity of PLA1 within vespid species. Here, we address PLA1-based cross-reactivity among ten clinically relevant Hymenoptera venoms from Neotropical and temperate regions including Polybia paulista (paulistinha) venom and Vespula vulgaris (yellow jacket) venom. In order to evaluate cross-reactivity, sera of mice sensitized with recombinant PLA1 (rPoly p 1) from P. paulista wasp venom were used. Pronounced IgE and IgG based cross-reactivity was detected for wasp venoms regardless the geographical region of origin. The cross-reactivity correlated well with the identity of the primary sequence and 3-D models of PLA1 proteins. In contrast, these mice sera showed no reaction with honeybee (HBV) and fire ant venom. Furthermore, sera from patients monosensitized to HBV and fire ants did not recognize the rPoly p 1 in immunoblotting. Our findings reveal the presence of conserved epitopes in the PLA1s from several clinically relevant wasps as major cause of PLA1-based in vitro cross-reactivity. These findings emphasize the limitations but also the potential of PLA1-based HVA diagnostics. Copyright © 2017 Elsevier Ltd. All rights reserved.

HYMENOPTERA ALLERGENS: FROM VENOM TO VENOME

Edzard eSpillner

2014-02-01

Full Text Available In Western Europe hymenoptera venom allergy primarily relates to venoms of the honeybee and the common yellow jacket. In contrast to other allergen sources, only a few major components of hymenoptera venoms had been characterized until recently. Improved expression systems and proteomic detection strategies have allowed the identification and characterization of a wide range of additional allergens. The field of hymenoptera venom allergy research has moved rapidly from focusing on venom extract and single major allergens to a molecular understanding of the entire venome as a system of unique and characteristic components. An increasing number of such components has been identified, characterized regarding function and assessed for allergenic potential. Moreover, advanced expression strategies for recombinant production of venom allergens allow selective modification of molecules and provide insight into different types of IgE reactivities and sensitization patterns. The obtained information contributes to an increased diagnostic precision in hymenoptera venom allergy and may serve for monitoring, reevaluation and improvement of current therapeutic strategies.

Among venomous animals, Hymenoptera have been suggested as a rich source of natural toxins. Due to their broad ecological diversity, venom from Hymenoptera insects (bees, wasps and ants) have evolved differentially thus widening the types and biological functions of their components. To date, insect toxinology analysis have scarcely uncovered the complex composition of bee, wasp and ant venoms which include low molecular weight compounds, highly abundant peptides and proteins, including several allergens. In Hymenoptera, these complex mixtures of toxins represent a potent arsenal of biological weapons that are used for self-defense, to repel intruders and to capture prey. Consequently, Hymenoptera venom components have a broad range of pharmacological targets and have been extensively studied, as promising sources of new drugs and biopesticides. In addition, the identification and molecular characterization of Hymenoptera venom allergens have allowed for the rational design of component-resolved diagnosis of allergy, finally improving the outcome of venom immunotherapy (VIT). Until recently, a limited number of Hymenoptera venoms had been unveiled due to the technical limitations of the approaches used to date. Nevertheless, the application of novel techniques with high dynamic range has significantly increased the number of identified peptidic and proteinaceous toxins. Considering this, the present review summarizes the current knowledge about the most representative Hymenoptera venom peptides and proteins which are under study for a better understanding of the insect-caused envenoming process and the development of new drugs and biopesticides.

Adult chalcidoid species were reared from galls, and eggs obtained from dissected female ovaries were examined using scanning electron microscopy (SEM. The shape of the eggs varies from oval to elongate and tapered at both ends. Eggs of Eurytomidae as well as some Eulophidae, Eupelmidae and Pteromalidae are equipped with a peduncle at the anterior end. We found a positive correlation between long eggs and long ovipositors and confirmed the expectation that eggs of endoparasitoids are generally shorter and narrower than eggs of ectoparasitoids. We were able to locate the sperm entrance or micropyle at the anterior pole of eggs of several species. It is situated at the anterior end of the egg and at the end of the peduncle when present.

Full Text Available Hymenoptera is one of the four largest insect order (the other three are Coleoptera, Diptera, and Lepidoptera. There are curerently over 115 000 described Hymenoptera species. It is clear that Hymenoptera is one of the major components of insect biodiversity. However, Hymenoptera biodiversity is affected by ecology, environment, and ecosystem management. In an agricultural areas, the spatial structure, habitat diversity, and habitat composition may vary from cleared landscapes to structurally rich landscape. Thus, it is very likely that such large-scale spatial patterns (landscape effects may influence local biodiversity and ecological functions. Therefore, the objective of this research were to study diversity and configuration elements of agricultural landscapes at Cianjur Watershed with geographical information sytems (GIS and its influence on Hymenoptera biodiversity. The structural differences between agricultural landscapes of Nyalindung, Gasol, and Selajambe were characterized by patch analyst with ArcView 3.2 of digital land use data. Results indicated that class of land uses of Cianjur Watershed landscape were housing, mixed gardens, talun and rice, vegetable, and corn fields. Landscape structure influenced the biodiversity of Hymenoptera. Species richness and the species diversity were higher in Nyalindung landscape compare to Gasol and Selajambe landscape.

Full Text Available Hymenoptera venoms are complex mixtures containing simple organic molecules, proteins, peptides, and other bioactive elements. Several of these components have been isolated and characterized, and their primary structures determined by biochemical techniques. These compounds are responsible for many toxic or allergic reactions in different organisms, such as local pain, inflammation, itching, irritation, and moderate or severe allergic reactions. The most extensively characterized Hymenoptera venoms are bee venoms, mainly from the Apis genus and also from social wasps and ant species. However, there is little information about other Hymenoptera groups. The Apis venom presents high molecular weight molecules - enzymes with a molecular weight higher than 10.0 kDa - and peptides. The best studied enzymes are phospholipase A2, responsible for cleaving the membrane phospholipids, hyaluronidase, which degrades the matrix component hyaluronic acid into non-viscous segments and acid phosphatase acting on organic phosphates. The main peptide compounds of bee venom are lytic peptide melittin, apamin (neurotoxic, and mastocyte degranulating peptide (MCD.

Patterns of restriction fragment length polymorphisms (RFLP) of European Vespinae were more similar within genera than between them. Distance trees were constructed that support the hypothesis of monophyly of the genera Vespula and Dolichovespula. Within the genus Vespula, V. germanica was more closely related to V. rufa than to V. vulgaris. The position of the genus Vespa remained uncertain due to the precision limits of the RFLP technique.

Caste differences in Pseudopolybia compressa (Hymenoptera: Vespidae: Polistinae

Full Text Available Studies of morphological caste syndromes in the tribe Epiponini help us to understand the evolution of social behavior in insects. Few studies have integrated morphological syndromes of various species from the same or distinct genera. We studied morphological differences between castes from three colonies of Pseudopolybia compressa de Saussure, 1854, in order to relate their caste syndrome with those of other species in the genus. We took eight morphometric measures and females were classified in relation to ovarian development and spermathecal contents. Females of Colony 1 (C1 present a higher distinction between castes than females of Colonies 2 and 3 (C2 and C3, and, in general, queens of the three colonies are larger than workers in some measures but smaller in others. In Pseudopolybia Dalla Torre, 1894, shape rather than size is a more important trait in caste divergence.

Component Resolved Diagnosis in Hymenoptera Anaphylaxis.

Tomsitz, D; Brockow, K

2017-06-01

Hymenoptera anaphylaxis is one of the leading causes of severe allergic reactions and can be fatal. Venom-specific immunotherapy (VIT) can prevent a life-threatening reaction; however, confirmation of an allergy to a Hymenoptera venom is a prerequisite before starting such a treatment. Component resolved diagnostics (CRD) have helped to better identify the responsible allergen. Many new insect venom allergens have been identified within the last few years. Commercially available recombinant allergens offer new diagnostic tools for detecting sensitivity to insect venoms. Additional added sensitivity to nearly 95% was introduced by spiking yellow jacket venom (YJV) extract with Ves v 5. The further value of CRD for sensitivity in YJV and honey bee venom (HBV) allergy is more controversially discussed. Recombinant allergens devoid of cross-reactive carbohydrate determinants often help to identify the culprit venom in patients with double sensitivity to YJV and HBV. CRD identified a group of patients with predominant Api m 10 sensitization, which may be less well protected by VIT, as some treatment extracts are lacking this allergen. The diagnostic gap of previously undetected Hymenoptera allergy has been decreased via production of recombinant allergens. Knowledge of analogies in interspecies proteins and cross-reactive carbohydrate determinants is necessary to distinguish relevant from irrelevant sensitizations.

PO 214 , a short life daughter product of RN 222 , was measured by alpha-ray spectrometry of a atmospheric particles sampled on Millipore filters (0.8 μm pore) at Sao Jose dos Campos (23 0 12'S, 45 0 51'W) and Cachoeira Paulista (22 0 41'S, 45 0 00'W). The infleunce of rainfall on the atmospheric Po 214 was studied at Sao Jose dos Campos. The mean activity was 98 pCi/m 3 for dry days (without rain during the preceding two days). On the contrary a low mean activity of 35 pCi/m 3 was observed for high pluviometry days from 08/30 to 10/26 for which total rainfall was 365.5 mm. At Cachoeria Paulista the Po 214 activity was correlated with the stability of the air (measured by the Richardson number), showing an accumaltion of natural radioactive aerosols during periods of higher stability of the lower atmosphere.

Most reports published in the field of forensic entomology are focused on Diptera and neglect the Hymenoptera community. However, Hymenoptera are part of the entomofaunal colonization of a dead body. The use of Hymenoptera parasitoids in forensic entomology can be relevant to evaluate the time of death. Hymenoptera parasitoids of the larvae and pupae of flies may play an important role in the estimation of the post-mortem period because their time of attack is often restricted to a small, well-defined window of time in the development of the host insect. However, these parasitoids can interfere with the developmental times of colonizing Diptera, and therefore a better understanding of their ecology is needed. The work reported here monitored the presence of adult Hymenoptera parasitoids on decaying pig carcasses in an urban biotope during the summer season (from May to September). Six families and six species of parasitoids were recorded in the field: Aspilota fuscicornis Haliday (Braconidae), Alysia manducator Panzer, Nasonia vitripennis Walker (Pteromalidae), Tachinaephagus zealandicus Ashmead (Encyrtidae), Trichopria sp. (Diapriidae), and Figites sp. (Figitidae). In the laboratory, five species emerged from pupae collected in the field: Trichopria sp., Figites sp., A. manducator, N. vitripennis, and T. zealandicus. These five species colonize a broad spectrum of Diptera hosts, including those species associated with decomposing carcasses, namely those from the families Calliphoridae, Muscidae, Fanniidae, and Sarcophagidae.

2004-03-01

Full Text Available Abstract Background Social wasps in the subfamily Polistinae (Hymenoptera: Vespidae have been important in studies of the evolution of sociality, kin selection, and within colony conflicts of interest. These studies have generally been conducted within species, because a resolved phylogeny among species is lacking. We used nuclear DNA microsatellite flanking sequences, mitochondrial COI sequence, and morphological characters to generate a phylogeny for the Polistinae (Hymenoptera using 69 species. Results Our phylogeny is largely concordant with previous phylogenies at higher levels, and is more resolved at the species level. Our results support the monophyly of the New World subgenera of Polistini, while the Old World subgenera are a paraphyletic group. All genera for which we had more than one exemplar were supported as monophyletic except Polybia which is not resolved, and may be paraphyletic. Conclusion The combination of DNA sequences from flanks of microsatellite repeats with mtCOI sequences and morphological characters proved to be useful characters establishing relationships among the different subgenera and species of the Polistini. This is the first detailed hypothesis for the species of this important group.

Numerous publications indicate that the prevalence of some infectious, neoplastic and immunological diseases are associated with ABO blood groups. The aim of this study was to verify whether ABO and Rh blood groups are associated with severe anaphylactic reactions after Hymenoptera stings. A study was undertaken of 71,441 Caucasian subjects living in the same geographic area. The study group included 353 patients with diagnosed systemic anaphylaxis to Hymenoptera venom. Control group included 71,088 healthy blood donors. Frequencies of ABO and Rhesus groups in the study and control groups were compared using univariate and multivariate analyses. No statistically significant interactions were observed between the ABO blood group and anaphylactic reactions to Hymenoptera.

A new scenario of bioprospecting of Hymenoptera venoms through proteomic approach

Directory of Open Access Journals (Sweden)

LD Santos

2011-01-01

Full Text Available Venoms represent a huge and essentially unexplored reservoir of bioactive components that may cure diseases that do not respond to currently available therapies. This review select advances reported in the literature from 2000 to the present about the new scenario of Hymenoptera venom composition. On account of new technologies in the proteomic approach, which presents high resolution and sensitivity, the combination of developments in new instruments, fragmentation methods, strategic analysis, and mass spectrometry have become indispensable tools for interrogation of protein expression, molecule interaction, and post- translational modifications. Thus, the biochemical characterization of Hymenoptera venom has become a major subject of research in the area of allergy and immunology, in which proteomics has been an excellent alternative to assist the development of more specific extracts for diagnosis and treatment of hypersensitive patients to Hymenoptera venoms.

The natural history of stings, the clinical reaction of the patient and in vivo and in vitro tests are necessary parameters to assess before initiating Hymenoptera venom immunotherapy. In the decision to initiate immunotherapy with Hymenoptera venom, it is not usual to evaluate the natural history of the disease, which seems to be self-limiting and therefore of variable clinical significance. Our aim was to determine the natural history of Hymenoptera hypersensitivity over 4 consecutive years in a rural Mediterranean population. An epidemiological study of Hymenoptera sting reactions and possible sensitivity was carried out in 145 randomly selected subjects out of a rural Mediterranean population of 600. Seventy-two subjects, including those with a history of anaphylaxis, completed the 4-year study. The nature of their clinical reactions, age, sex, history of atopy, profession, family history of reactions to Hymenoptera insects, time elapsed since the last sting, number of stings and specific IgE and IgG were determined (the latter, to the three most important insects in the area: Apis mellifera, Polistes dominulus, and Vespula germanica). Of the 72 subjects, four subjects had systemic reactions (SR), 23 had large local reaction (LLR) and all the others (117) was minor local reactions. None who had experienced an SR had a repeat SR when re-stung over the 4-year study. Of those with LLR, 12 subjects had the same type of reaction and 11 experienced more mild local reactions when re-stung. In the SR and local reaction groups, IgE to honey bee (Hb) increased significantly during the study period, whereas in those with only LLR, specific IgE to wasp (Polistes) decreased. Specific IgG to Polistes and Vespula (wasps) decreased significantly, whereas there was no change in the specific IgG to Hb in any of the groups. The number of stings per year decreased at the end of the study in all groups, but positive-specific IgG was higher in subjects with the greatest number of

Stings of hymenoptera can induce IgE-mediated hypersensitivity reactions in venom-allergic patients, ranging from local up to severe systemic reactions and even fatal anaphylaxis. Allergic patients' quality of life can be mainly improved by altering their immune response to tolerate the venoms...... by injecting increasing venom doses over years. This venom-specific immunotherapy is highly effective and well tolerated. However, component-resolved information about the venoms has increased in the last years. This knowledge is not only able to improve diagnostics as basis for an accurate therapy......, but was additionally used to create tools which enable the analysis of therapeutic venom extracts on a molecular level. Therefore, during the last decade the detailed knowledge of the allergen composition of hymenoptera venoms has substantially improved diagnosis and therapy of venom allergy. This review focuses...

To analyze the ametropy, way of acquisition, the care and complications related to contact lens wear among medical students from Faculdade de Medicina de Botucatu da Universidade Estadual Paulista-UNESP--Botucatu (SP). Questionnaire applied to students from the 1st to the 6th year of the Medical school of the Faculdade de Medicina de Botucatu da Universidade Estadual Paulista-UNESP--Botucatu (SP), forming an analytical cross-sectional survey. 27.4% of the students use contact lenses, and among them 94.8% use soft contact lenses and 98% have negative degree. 46.9% discard their contact lens monthly. 63.9% have an average daily use of 14 hours, 14.1% acquire the contact lenses from optician stores or at pharmacies and 46.5% of the students clean their contact lenses when they put them on and take them off. Regarding complications, 51.0% reported ocular redness; 44.5%, blurred vision; and 42.6%, foreign body sensation, whereas only 4 students reported "keratitis". We concluded that the inadequate adaptation that occurs even in users knowledgeable about this issue such as medical students, has increased the risk of complications. This fact indicates that more attention must be paid to contact lens care in order to prevent permanent visual deficit.

Fire is one of the commonest disturbances worldwide, transforming habitat structure and affecting ecosystem functioning. Understanding how species respond to such environmental disturbances is a major conservation goal that should be monitored using functionally and taxonomically diverse groups such as Hymenoptera. In this respect, we have analyzed the taxonomic and functional response to fire and post-fire management of a Hymenoptera community from a Mediterranean protected area. Thus, Hymenoptera were sampled at fifteen sites located in three burnt areas submitted to different post-fire practices, as well as at five sites located in peripheral unburnt pine forest. A total of 4882 specimens belonging to 33 families, which were classified into six feeding groups according to their dietary preferences, were collected. ANOVA and Redundancy Analyses showed a taxonomic and functional response to fire as all burnt areas had more Hymenoptera families, different community composition and higher numbers of parasitoids than the unburnt area. Taxonomic differences were also found between burnt areas in terms of the response of Hymenoptera to post-fire management. In general the number of parasitoids was positively correlated to the number of potential host arthropods. Parasitoids are recognized to be sensitive to habitat changes, thus highlighting their value for monitoring the functional responses of organisms to habitat disturbance. The taxonomic and functional responses of Hymenoptera suggest that some pine-forest fires can enhance habitat heterogeneity and arthropod diversity, hence increasing interspecific interactions such as those established by parasitoids and their hosts.

Cross-reacting carbohydrate determinants and hymenoptera venom allergy.

Science.gov (United States)

Brehler, Randolf; Grundmann, Sonja; Stöcker, Benedikt

2013-08-01

Insect venom allergy is an important cause of anaphylaxis. Venom immunotherapy assume the clear identification of the culprit insect, but this is impeded by Immunoglobulin E (IgE) antibodies to cross reactive carbohydrate determinant (CCD) epitopes of common glycoproteins. Here we give an overview about inducers, importance, and relevance of anti-N-Glycan CCD IgE antibodies. Pollen exposure and insect stings induce anti-CCD IgE antibodies interfering with in-vitro tests for allergy diagnosis due to extensive IgE cross-reactivity. Instead of being biologically active these antibodies are irrelevant for allergic reactions due to hymenoptera stings. The general response of the immune system to the ubiquitous exposure to N-glycan containing glycoproteins is still a matter of debate. CCD specific IgG antibodies in sera of bee keepers suggest tolerance induction due to high-dose exposure. Tolerance induction by pollen and food glycoproteins has not been proved. Hymenoptera stings and pollen exposure induce anti-CCD IgE. In regard to anaphylaxis due to Hymenoptera stings these antibodies are not clinically relevant, but they are important for the specificity of in-vitro tests proving insect venom allergy. The introduction of component based diagnostic IgE testing improves the specificity of in-vitro tests if proteins devoid of CCD epitopes are used.

Foram aplicados questionários semi-estruturados às empresas e produtores listados por agentes institucionais da região. Observou-se que a ação coletiva aparece como uma estratégia fundamental para minimizar os problemas enfrentados pelo setor de produção, uma vez que a dinâmica de mercado vem atuando no sentido de selecionar os produtores de leite por escala de produção, qualidade da matéria-prima e profissionalismo na gestão dos negócios. As empresas entrevistadas apresentam carência de programas de acompanhamento de mão-de-obra, planejamento estratégico, tecnologia de informação e investimento em marketing. A falta de conhecimento sobre os benefícios (ou existência de algumas ferramentas de gestão pode justificar tais resultados, e comprometem seriamente a competitividade da empresa. Porém, a solução está sob controle direto da própria empresa. Tais iniciativas mostram-se como alternativas para uma melhor inserção da produção e da indústria de laticínios no mercado. Palavras-chave: Leite, Competitividade, Mercado.

Head capsule characters in the Hymenoptera and their phylogenetic implications

Lars Vilhelmsen

2011-09-01

Full Text Available The head capsule of a taxon sample of three outgroup and 86 ingroup taxa is examined for characters of possible phylogenetic significance within Hymenoptera. 21 morphological characters are illustrated and scored, and their character evolution explored by mapping them onto a phylogeny recently produced from a large morphological data set. Many of the characters are informative and display unambiguous changes. Most of the character support demonstrated is supportive at the superfamily or family level. In contrast, only few characters corroborate deeper nodes in the phylogeny of Hymenoptera.

The short half-life descendents from radon measured in Sao Jose dos Campos and Cachoeira Paulista, Brazil, and its correlation with meteorological data

International Nuclear Information System (INIS)

Andrade Marinho, E.V. de.

1985-09-01

The correlations between the activity of the short half-life radon decay products in the low atmosphere and the meterological parameters, measuring the atmospheric polonium 214 are studied. The aerosols were collected on membrane filters and analysed by alpha spectrometry. Measurements have been made in Sao Jose dos Campos and Cachoeira Paulista, in Brazil. At S. Jose dos Campos the influence of the pluviometry on the concentration of atmospheric Po 214 has been analysed, showing that high activity correspond to low pluviometry and inversely, low activities correspond to high pluviometry. At Cachoeira Paulista, the variation in the atmospheric Po 214 activity in corresation with the air stability, measured, showing the accumulation of radioactive aerosols during the greater stability in the the lower atmospheric layers, was studied.

Wasps are the cause of an increasing mastitis problem in dairy cattle in Israel.

Science.gov (United States)

Yeruham, I; Braverman, Y; Schwimmer, A

1998-07-01

The German wasp Vespula germanica (Fabr.) (Hymenoptera: Vespidae) has been observed to injure dairy cows teats, causing lesions which can lead to mastitis. The number of dairy herds in Israel reported to be affected in this way has increased from five prior to 1989 to 32 from 1989 to 1993. Likewise, the geographical distribution of the colonies of these wasps has expanded from the Galilee to the northern Negev. Most cases of mastitis appeared during August and September when the wasps were most active; the predominant organism isolated was Streptococcus dysgalactiae. Apparently the wasps served as a vector in spreading S. dysgalactiae infection in the herds. More adult cows than first-calving cows were affected. The teats of the front quarters were more affected than those of the hind quarters.

Full Text Available The understory in forest plantations can increase richness and diversity of natural enemies due to greater plant species richness. The objective of this study was to test the hypothesis that the presence of the understory and climatic season in the region (wet or dry can increase the richness and abundance of Hymenoptera parasitoids in Eucalyptus plantations, in the municipality of Belo Oriente, Minas Gerais State, Brazil. In each eucalyptus cultivation (five areas of cultivation ten Malaise traps were installed, five with the understory and five without it. A total of 9,639 individuals from 30 families of the Hymenoptera parasitoids were collected, with Mymaridae, Scelionidae, Encyrtidae and Braconidae being the most collected ones with 4,934, 1,212, 619 and 612 individuals, respectively. The eucalyptus stands with and without the understory showed percentage of individuals 45.65% and 54.35% collected, respectively. The understory did not represent a positive effect on the overall abundance of the individuals Hymenoptera in the E. grandis stands, but rather exerted a positive effect on the specific families of the parasitoids of this order.

Orlando Tobias Silveira

2008-01-01

Full Text Available A phylogenetic analysis is presented of subgenera and species-groups of Mischocyttarus de Saussure, the largest genus of social wasps. The analysis is based on 62 morphological and nest architecture characters, coded for 71 terminals representing much of the taxonomic diversity within the genus, plus three outgroup terminals representing other polistine tribes. The main conclusions about phylogenetic relationships within the genus are based on parsimony analysis under implied weights. Monophyly of Mischocyttarus is confirmed as well as that of most of the previously recognized subgenera: Mischocyttarus s. str., Clypeopolybia, Monogynoecus, Scytokeraia, Phi, Kappa, Megacanthopus and Omega sensu Richards (1978. Haplometrobius as conceived by Richards (1978 is not a monophyletic taxon, but some of its species-groups are monophyletic. The groups of M.artifex and M.cerberus are raised to subgenus level, and a new concept of Haplometrobius restricts it to the group of M.iheringi (the type species of this subgenus in the sense of this work. The concept of subgenus Omega is widened to include the species-groups of M.surinamensis and M.prominulus. Besides the new subgeneric classification presented, limits and diagnoses of all species-groups of the subgenera Phi and Haplometrobius sensu Richards (1978 are discussed, and a new key for all subgenera and species-groups of Mischocyttarus is also presented.O artigo apresenta um estudo filogenético dos subgêneros e grupos de espécies de Mischocyttarus de Saussure, o maior dos gêneros de vespas sociais. A análise é baseada em 62 caracteres morfológicos e de arquitetura de ninhos, codificados para 71 terminais representantes da diversidade taxonômica do gênero e mais três terminais correspondentes às outras três tribos de Polistinae. As conclusões principais sobre relações filogenéticas são extraídas de análises usando pesagem implícita de caracteres. O monofiletismo de Mischocyttarus é confirmado, assim como da maioria dos subgêneros previamente reconhecidos: Mischocyttarus s. str., Clypeopolybia, Monogynoecus, Scytokeraia, Phi, Kappa, Megacanthopus e Omega sensu Richards (1978. Haplometrobius tal como concebido por Richards (1978 não é um táxon monofilético, mas alguns de seus grupos de espécies são monofiléticos. Os grupos de M.artifex e M.cerberus são elevados à categoria de subgênero e um novo conceito mais restrito de Haplometrobius é adotado, circunscrito ao grupo de M.iheringi (a espécie tipo desse subgênero. O conceito do subgênero Omega é ampliado para incluir os grupos de espécies de M.surinamensis e M.prominulus. Além de uma nova classificação subgenérica, acompanhada de chave de identificação, discute-se também os limites e diagnoses de todos os grupos de espécies dos subgêneros Phi e Hamplometrobius sensu Richards (1978.

Full Text Available The aim of this study was to compare biological aspects of the Pachodynerus species occurring in the Parque Municipal das Araucárias, Guarapuava, Paraná, Southern Brazil. It was carried from December 2001 to December 2004. Forty one nests belonging to 5 species were collected, of which 17 Pachodynerus guadulpensis, 15 Pachodynerus sp., 1 Pachodynerus argentinus, 1 Pachodynerus ca guadulpensis and 7 Pachodynerus nasidens. The nesting activity of Pachodynerus sp., P. argentinus and P. guadulpensis occurred in similar periods, from December to March, with the exception of P.guadulpensis, that built one nest in October. Pachodynerus ca guadulpensis nested in March and P. nasidens from January to April. The nests of Pachodynerus species present a very similar architecture, comprising a linear series of cylindrical cells that fit perfectly into each other forming a continuous tube. With these results we were able to conclude that, even though Pachodynerus species present common characteristics, such as nest architecture, nesting activities and habitats in which they occur, the used resources, mortality rates, etc., vary among groups of species occurring in different regions.O objetivo deste trabalho foi comparar aspectos biológicos das espécies de Pachodynerus que ocorrem no Parque Municipal das Araucárias, Guarapuava, Paraná, Sul do Brasil. Ele foi realizado de dezembro de 2001 a dezembro de 2004. Quarenta e um ninhos de cinco espécies foram coletados sendo 17 de Pachodynerus guadulpensis, 15 de Pachodynerus sp., um de Pachodynerus argentinus, um de Pachodynerus ca guadulpensis e sete de Pachodynerus nasidens. As nidificações de Pachodynerus sp., P. argentinus e P. guadulpensis ocorreram de dezembro a março, com exceção de P. guadulpensis, que construiu um ninho em outubro. Pachodynerus ca guadulpensis nidificou em março e P. nasidens de janeiro a abril. Os ninhos de todas as espécies de Pachodynerus apresentaram arquitetura similar, com uma série linear de células cilíndricas que se encaixam perfeitamente umas nas outras, formando um tubo contínuo. Pelos resultados deste estudo nós concluímos que, mesmo apresentando características em comum, como a arquitetura dos ninhos, atividades de nidificação e habitats onde ocorrem, os recursos usados pelas espécies de Pachodynerus bem como as suas taxas de mortalidades, etc., variam entre grupos de espécies que ocorrem em diferentes regiões.

Hymenoptera venom allergy is a typical IgE-mediated reaction caused by sensitization to 1 or more allergens of the venom, and accounts for 1.5% to 34% of all cases of anaphylaxis. Patients suffering from mastocytosis are more susceptible to the anaphylactic reactions to an insect sting. This article aims to answer the most important clinical questions raised by the diagnosis and treatment of insect venom allergy in mastocytosis patients. Total avoidance of Hymenoptera is not feasible, and there is no preventive pharmacologic treatment available, although venom immunotherapy reduces the risk of subsequent systemic reactions.

Attraction of Vespula germanica (Hymenoptera: Vespidae) foragers by conspecific heads.

Science.gov (United States)

d'Adamo, P; Corley, J C; Lozada, M

2001-08-01

The socialwasp Vespula germanica (F.) is a serious pest in many regions it has invaded. Control programs to reduce its populations are commonly based on the use of poison baits. These baits also attract nonpestiferous invertebrates and vertebrates. In this work we studied the attraction of V. germanica foragers by conspecific worker squashes, comparing the effect of head and abdomen squashes in wasps behavior. We found that head squashes attract V. germanica foragers, elicit landing and transportation to nests. Furthermore, the addition of squashed heads to a protein bait increased attraction. This could be an alternative to improve baiting programs.

2001-08-01

Vespula germanica (F.) is a social vespid that has invaded many parts of the world, including Argentina. This wasp usually becomes a pest, affecting several economic activities. It also may impact the host community through predation or competition. The purpose of our study was to field test toxic baiting for reduction of wasp abundance. Wasps were poisoned with 0.1% fipronil mixed with raw minced beef in two beech forest sites on 20 February 2000 in northwestern Patagonia. All nests (46) within the two 6-ha sites with poisoned bait stations were killed, whereas Malaise traps in those sites captured 81.1% fewer wasps at the end of the season than traps in the two control sites. The average reduction of forager wasps on nontoxic baits was 87%. Fipronil was very effective in controlling wasp numbers, although there are limitations to the method, especially concerning conservation purposes. Toxic baiting can be useful in controlling wasp numbers in honey bee hive yards, farms, and parks.

Fernandez, J; Blanca, M; Soriano, V; Sanchez, J; Juarez, C

1999-08-01

Systemic allergic reactions to Hymenoptera venom occur in a percentage that varies from 0.4 to 3.3%. Epidemiological studies indicate that from 15 to 25% of the general population can be sensitized to different Hymenoptera venom as well as the fact that the degree of exposure may be related to the prevalence found in those studies. The objective of this study was to evaluate the prevalence of insect sting allergy and the venom sensitization in a rural population to three Hymenoptera previously found in the area: Polistes dominulus (Pd), Vespula germanica (Vg) and honey bee (Hb). A rural community located in the south-east of Spain, close to the Mediterranean Sea, was selected since the stinging Hymenoptera having been previously identified. A random sample of 310 subjects from the village census was studied. A questionnaire and a serum sample were obtained from every patient. The evaluation was conducted by a family doctor, who focused on the reactions to Hymenoptera sting, age, sex, occupation, atopia, previous Hymenoptera sting, stinging insect, interval to last sting and average stings per year. RAST to Hymenoptera venoms were also determined. The prevalence of systemic reactions was 2.3% (57.6% of them had a positive RAST). Large local reactions were found in 26.4% (only 28.5% of them had a positive RAST). Asymptomatic sensitization (positive RAST) was observed in 16.4% of subjects without reaction. Only a weak correlation between subjects with less than 3 years' interval to last sting exposure and positive RAST results was noted, whether they presented with a clinical reaction or not (P < 0.05). The prevalence of systemic sting reactions in our rural community is higher than other general populations in the same Mediterranean area, and similar to other rural populations studied. The degree of exposure influences not only the prevalence found but also the detection of specific serum IgE.

Morphology and function of the ovipositor mechanism in Ceraphronoidea (Hymenoptera, Apocrita

Directory of Open Access Journals (Sweden)

Andrew Ernst

2013-08-01

Full Text Available The ovipositor of apocritan Hymenoptera is an invaluable source of phylogenetically relevant characters, and our understanding of its functional morphology stands to enlighten us about parasitoid life history strategies. Although Ceraphronoidea is one of the most commonly collected Hymenoptera taxa with considerable economic importance, our knowledge about their natural history and phylogenetic relationships, both to other apocritan lineages and within the superfamily itself, is limited. As a first step towards revealing ceraphronoid natural diversity we describe the skeletomuscular system of the ceraphronoid ovipositor for the first time. Dissections and Confocal Laser Scanning Microscopy 3D media files were used to visualize the ovipositor complex and to develop character concepts. Morphological structures were described in natural language and then translated into a character-character state format, whose terminology was linked to phenotype-relevant ontologies. Four unique anatomical phenotypes were revealed: 1. The first valvifer (gonangulum of the genus Trassedia is composed of two articulating sclerites, a condition present only in a few basal insect taxa. The bipartition of the first valvifer in Trassedia is most likely secondary and might allow more rapid oviposition. 2. Ceraphronoids, unlike other Hymenoptera, lack the retractor muscle of the terebra; instead the egg laying device is retracted by the seventh sternite. 3. Also unlike other Hymenoptera, the cordate apodeme and the anterior flange of the second valvifer are fused and compose one ridge that serves as the site of attachment for the dorsal and ventral T9-second valvifer muscles. Overall, the ceraphronoid ovipositor system is highly variable and can be described by discrete, distinguishable character states. However, these differences, despite their discrete nature, do not reflect the present classification of the superfamily and might represent parallelisms driven by host

The reported prevalence of allergic systemic reactions to hymenoptera venom occur in up to 3.3% and large local reactions occur in 17% in the general population. To investigate the prevalence of hymenoptera sting allergy in a group of veterinary medicine students from Monterrey, Nuevo Leon, Mexico. A transverse and observational study was done with 64 students of veterinary medicine. We conducted a questionnaire about the students' history of insect allergy and atopy. Skin test with allergenic extracts of bee and ant were practiced to all subjects. We performed aeroallergen skin prick test to the subjets with suspected atopy. Students age ranged from 17 to 25 years (mean 20.2) and 37 were males. Twenty students (31.3%) had clinical history of atopy and positive skin tests to aeroallergens. On the other hand, 5 students (7.8%), including 2 atopic, had suffered large local reactions, but none of them had suffered systemic reactions. Bee and ant skin tests were positive in 15.6% and 31.3% of the students respectively. There was no difference in the prevalence of hymenoptera allergy between atopic and non atopic subjects (p < 0.05). Further, the frequency of atopy in subjects with positive skin tests for bee and ant was 50%. The prevalence of large local reactions and hymenoptera sensitization found in this group was similar to that found in other epidemiologic studies.

Although apomixis is the most common form of parthenogenesis in diplodiploid arthropods, it is uncommon in the haplodiploid insect order Hymenoptera. We found a new type of spontaneous apomixis in the Hymenoptera, completely lacking meiosis and the expulsion of polar bodies in egg maturation division, on the thelytokous strain of a parasitoid wasp Meteorus pulchricornis (Wesmael) (Braconidae, Euphorinae) on pest lepidopteran larvae Spodoptera litura (Fabricius) (Noctuidae). The absence of the meiotic process was consistent with a non-segregation pattern in the offspring of heterozygous females, and no positive evidence was obtained for the induction of thelytoky by any bacterial symbionts. We discuss the conditions that enable the occurrence of such rare cases of apomictic thelytoky in the Hymenoptera, suggesting the significance of fixed heterosis caused by hybridization or polyploidization, symbiosis with bacterial agents, and occasional sex. Our finding will encourage further genetic studies on parasitoid wasps to use asexual lines more wisely for biological control.

RB. Querino

Full Text Available Parasitoids are of great importance to forest ecosystems due to their ecological role in the regulation of the population of other insects. The species richness and abundance of parasitoids in the forest canopy and understory, both on the borders and in the interior of a tropical forest reserve in Central Amazonia were investigated. For a 12-month period, specimen collections were made every 15 days from suspended traps placed in the forest canopy and in the understory strata, both on the border and in the interior of forest areas. A total of 12,835 Hymenoptera parasitoids from 23 families were acquired. Braconidae, Diapriidae, Mymaridae, Eulophidae, and Scelionidae were the most represented in the area and strata samples. The results indicate that there were no significant differences in the species richness or abundance of Hymenoptera between the forest borders and the inner forest. The data does show that the presence of Hymenoptera is significantly greater in the understory in both the border and interior areas than in the canopy (vertical stratification. Aphelinidae and Ceraphronidae were significantly associated with the inner forest, while the other seven families with the border of the reserve. The abundance of Hymenoptera parasitoids presented seasonal variations during the year related to the rainy and dry seasons.

Evolution of Cuticular Hydrocarbons in the Hymenoptera: a Meta-Analysis.

Science.gov (United States)

Kather, Ricarda; Martin, Stephen J

2015-10-01

Chemical communication is the oldest form of communication, spreading across all forms of life. In insects, cuticular hydrocarbons (CHC) function as chemical cues for the recognition of mates, species, and nest-mates in social insects. Although much is known about the function of individual hydrocarbons and their biosynthesis, a phylogenetic overview is lacking. Here, we review the CHC profiles of 241 species of Hymenoptera, one of the largest and most important insect orders, which includes the Symphyta (sawflies), the polyphyletic Parasitica (parasitoid wasps), and the Aculeata (wasps, bees, and ants). We investigated whether these taxonomic groups differed in the presence and absence of CHC classes and whether the sociality of a species (solitarily vs. social) had an effect on CHC profile complexity. We found that the main CHC classes (i.e., n-alkanes, alkenes, and methylalkanes) were all present early in the evolutionary history of the Hymenoptera, as evidenced by their presence in ancient Symphyta and primitive Parasitica wasps. Throughout all groups within the Hymenoptera, the more complex a CHC the fewer species that produce it, which may reflect the Occam's razor principle that insects' only biosynthesize the most simple compound that fulfil its needs. Surprisingly, there was no difference in the complexity of CHC profiles between social and solitary species, with some of the most complex CHC profiles belonging to the Parasitica. This profile complexity has been maintained in the ants, but some specialization in biosynthetic pathways has led to a simplification of profiles in the aculeate wasps and bees. The absence of CHC classes in some taxa or species may be due to gene silencing or down-regulation rather than gene loss, as demonstrated by sister species having highly divergent CHC profiles, and cannot be predicted by their phylogenetic history. The presence of highly complex CHC profiles prior to the vast radiation of the social Hymenoptera indicates a

Cognitive plasticity in foraging Vespula germanica wasps.

Science.gov (United States)

D'Adamo, Paola; Lozada, Mariana

2011-01-01

Vespula germanica (F.) (Hymenoptera: Vespidae) is a highly invasive social wasp that exhibits a rich behavioral repertoire in which learning and memory play a fundamental role in foraging. The learning abilities of these wasps were analyzed while relocating a food source and whether V. germanica foragers are capable of discriminating between different orientation patterns and generalizing their choice to a new pattern. Foraging wasps were trained to associate two different stripe orientation patterns with their respective food locations. Their response to a novel configuration that maintained the orientation of one of the learned patterns but differed in other aspects (e.g. width of stripes) was then evaluated. The results support the hypothesis that V. germanica wasps are able to associate a particular oriented pattern with the location of a feeder and to generalize their choice to a new pattern, which differed in quality, but presented the same orientation.

2013-10-01

Full Text Available O objetivo do estudo foi interpretar e compreender a institucionalização da saúde pública paulista nos anos 1930-1940, com base na história das especialidades médicas. Foram analisadas novas fontes documentais em diálogo com a literatura existente, levando à identificação de novos indícios relativamente à questão eugênica e à presença de crenças religiosas de médicos como um movimento social. Os médicos, à medida que se especializavam como sanitaristas, propunham um projeto para elevar a raça brasileira, mesclando discursos higienistas com ações sanitárias. São Paulo buscou a primazia nesse projeto, por se acreditar um Estado detentor de uma raça já constituída de “homens historicamente saudáveis”. Crenças religiosas influenciaram o debate e as decisões de época para a ordem sanitária. Historicamente, o discurso sanitário compõe questões técnico-científicas com as político-ideológicas e as culturais, produzindo uma mescla dos diferentes interesses e perspectivas de ordem corporativa da profissão.

Archer, M S; Elgar, M A

2003-09-01

Many forensically important calliphorids, sarcophagids and muscids (Diptera) oviposit or larviposit on corpses only during the early stages of decomposition, yet individuals may attend bodies throughout decay. A field study was conducted to investigate how patterns of carcass use and attendance by some fly species are affected by decomposition. Five fly traps were placed in the forest and baited with whole, fresh piglet carcasses. Piglets decomposed in traps throughout the experiment, and all were skeletonized within 6 days. Flies were trapped at both early and late decomposition stages, and the species and population structures of trap catches were compared. More flies attended carcasses early rather than late in decay. For all species, flies attending early were mainly gravid females, but few gravid females attended late in decay. No females ovi- or larviposited late in decay, whereas females of all fly species deposited offspring early in decay. The number of males trapped of each species correlated positively with the number of females with eggs at early development stages. Observations were made of fly predation by European wasps Vespula germanica Fabricius (Hymenoptera, Vespidae) and jumper ants Myrmecia pilosula Smith (Hymenoptera, Formicidae) throughout the experiment. There was a higher risk for smaller fly species of being killed following predator attack. Ants and wasps attacked smaller fly species, whereas only wasps attacked larger fly species.

Database quality measurement should be considered a mandatory step to ensure an adequate level of confidence in data used for research and quality improvement. Several metrics have been described in the literature, but no standardized approach has been established. We aimed to describe a methodological approach applied to measure the quality and inter-rater reliability of a regional multicentric thoracic surgical database (Paulista Lung Cancer Registry). Data from the first 3 years of the Paulista Lung Cancer Registry underwent an audit process with 3 metrics: completeness, consistency, and inter-rater reliability. The first 2 methods were applied to the whole data set, and the last method was calculated using 100 cases randomized for direct auditing. Inter-rater reliability was evaluated using percentage of agreement between the data collector and auditor and through calculation of Cohen's κ and intraclass correlation. The overall completeness per section ranged from 0.88 to 1.00, and the overall consistency was 0.96. Inter-rater reliability showed many variables with high disagreement (>10%). For numerical variables, intraclass correlation was a better metric than inter-rater reliability. Cohen's κ showed that most variables had moderate to substantial agreement. The methodological approach applied to the Paulista Lung Cancer Registry showed that completeness and consistency metrics did not sufficiently reflect the real quality status of a database. The inter-rater reliability associated with κ and intraclass correlation was a better quality metric than completeness and consistency metrics because it could determine the reliability of specific variables used in research or benchmark reports. This report can be a paradigm for future studies of data quality measurement. Copyright © 2018 American College of Surgeons. Published by Elsevier Inc. All rights reserved.

Insect venom hypersensitivity can pose a threat to personnel deployed to a combat zone but the exposure risk in Afghanistan is currently unknown. This study was designed to assess the threat of Hymenoptera stings and associated allergic reactions in Afghanistan. Hymenoptera species were collected during a deployment to southern Afghanistan from June 2010 through January 2011. The literature was also reviewed to determine species of medically important Hymenoptera recorded in the region. The U.S. Army theater electronic medical data system was mined for ICD-9 codes associated with insect stings to determine the number of theater medical clinic encounters addressing insect sting reactions. Three species of flying hymenoptera were commonly encountered during the study period: Vespa orientalis L., Polistes wattii Cameron, and Vespula germanica (F.). A literature review also confirms the presence of honeybees (Apidae), numerous velvet ant (Mutillidae) species, and various ant (Formicidae) species all capable of stinging. No evidence was identified to suggest that fire ants (Solenopsis ssp.) are a threat in the region. Based on electronic medical records from the U.S. Central Command area of operations over a 2-year period, roughly 1 in 500 clinic visits involved a patient with a diagnosis of insect bite or sting. Cross-reactive members of all five flying Hymenoptera species commonly assessed for in Hymenoptera allergy evaluations are present in Afghanistan. The review of in-theater medical records confirms that insect stings pose an environmental threat to deployed service members.

A diagnosis of Hymenoptera venom allergy is based on clinical history and the results of skin tests and/or laboratory methods. To analyze the utility of available laboratory tests in diagnosing Hymenoptera venom allergy. Ninety-five patients with Hymenoptera venom allergy with a history of bee (35) or wasp (60) anaphylactic sting reaction and positive skin test with bee or wasp venom were included in this analysis. Specific immunoglobulin E (to bee venom extract, wasp venom extract, available recombinant molecules, and a basophil activation test with venom extracts were assessed in all the patients. Test sensitivity and specificity were calculated by using standard threshold values; then, receiver operating characteristic curve analysis was performed to compute optimal threshold values. Also, statistical analysis of the utility of different combinations of laboratory tests was performed. The optimal threshold values were revealed to be the following: 1.0 kIU/L for bee venom extract (sensitivity, 97.14%; specificity, 100%), 0.35 kIU/L for rApi m 1 (sensitivity, 68.57%; specificity, 100%), 1.22 kIU/L for wasp venom extract (sensitivity, 88.33%; specificity, 95.45%), 0.7 kIU/L for rVes v 5 (sensitivity, 86.67%; specificity, 95.45%), 1.0 kIU/L for rVes v 1 (sensitivity, 56.67%; specificity, 95.45%), 6.5% for basophil activation test with bee venom extract (sensitivity, 80%; specificity, 95.45%), and 4.5% for basophil activation test with wasp venom extract (sensitivity, 91.53%; specificity, 95.45%). The best test combinations were found to be the following: bee venom extract plus rApi m 1 (sensitivity, 97.14%; specificity, 95.45%) in bee and either wasp venom extract plus rVes v 5, or rVes v 5 plus rVes v 1 (both sensitivity, 98.33%; specificity, 95.45%) in patients with wasp venom allergy. Our analysis confirmed that currently used laboratory tests represent effective tools in diagnosing Hymenoptera venom allergy. Moreover, our probabilistic approach offered another

Mitochondrial DNA (mtDNA) haplotypes have been commonly used to determine honeybee subspecies relationships. To see if these markers would also be useful for comparisons of other Hymenoptera, we collected workers of six local species: Vespa crabro, the European hornet; Bombus impatiens, a bumblebee; Vespula germanica, the German yellow jacket; Polistes fuscatus, a paper wasp; Halictus ligatus, an alkali bee; and an unspecified Megachile, a leafcutting bee. MtDNA was isolated and digested with six endonucleases (AvaI, BglII, EcoRI, HindIII, HinfI, XbaI). The digested DNA was electrophoresed and visualized on agarose gels with comparison to a standard fragment marker and similarly treated honeybee mtDNA. The fragments obtained were also purified and sequenced. Phylogenetic relationships between six wasp and bee species, Apis mellifera, and several other similar aculeate Hymenoptera were determined. Newly defined DNA sequences were posted to GenBank (AF281169-AF281174).

Conclusions: The measurement of sIgE following spiking of rVes v 5 and rPol d 5 by conventional testing in Japanese subjects with sIgE against hornet and paper wasp venom, respectively, improved the sensitivity for detecting Hymenoptera venom allergy. Improvement testing for measuring sIgE levels against hornet and paper wasp venom has potential for serologically elucidating Hymenoptera allergy in Japan.

Injuries caused by the German yellow jacket Vespula germanica F. to dry and lactating dairy cows (Bos tourus) in 5 herds in Israel were monitored and adversely affected < or = 65% of the cows. Elimination of large alternative protein sources (placentas, sewage containing milk from the milking parlor), and prebaiting with high-quality minced meat (or fish) in adequate numbers of baiting cages around the dairy farm for several days, are necessary for successful control. Significant control was achieved after a shorter period of time when the dairy farm was surrounded by a smaller area of uncultivated land than by a larger area. At some dairy farms there were significant differences among numbers of wasps visiting the various cage sites and significant variability between baiting days. Efficient and significant control was achieved by minced meat bait containing 1.5% acephate (orthene) and 2% microencapsulated diazinon (Antikan). Wasps were totally repelled by minced meat bait containing 2.25% of a plant-derived bioinsecticide derived from Meliaceae (Ag1000). The potential of using Ag 1000 for repelling yellow jackets from teats and udders of dairy cows is discussed.

Actinomycetes with antimicrobial activity isolated from paper wasp (Hymenoptera: Vespidae: Polistinae) nests.

Madden, Anne A; Grassetti, Andrew; Soriano, Jonathan-Andrew N; Starks, Philip T

2013-08-01

Actinomycetes-a group of antimicrobial producing bacteria-have been successfully cultured and characterized from the nest material of diverse arthropods. Some are symbionts that produce antimicrobial chemicals found to protect nest brood and resources from pathogenic microbes. Others have no known fitness relationship with their associated insects, but have been found to produce antimicrobials in vitro. Consequently, insect nest material is being investigated as a new source of novel antimicrobial producing actinomycetes, which could be harnessed for therapeutic potential. To extend studies of actinomycete-insect associations beyond soil-substrate dwelling insects and wood boring excavators, we conducted a preliminary assessment of the actinomycetes within the nests of the paper wasp, Polistes dominulus (Christ). We found that actinomycetes were readily cultured from nest material across multiple invasive P. dominulus populations-including members of the genera Streptomyces, Micromonospora, and Actinoplanes. Thirty of these isolates were assayed for antimicrobial activity against the challenge bacteria Pseudomonas aeruginosa, Escherichia coli, Staphylococcus aureus, Serratia marcescens, and Bacillus subtilis. Sixty percent of isolates inhibited the growth of at least one challenge strain. This study provides the first assessment of bacteria associated with nests of P. dominulus, and the first record of antimicrobial producing actinomycetes isolated from social wasps. We provide a new system to explore nest associated actinomycetes from a ubiquitous and cosmopolitan group of insects.

2010-01-01

Full Text Available The observation of two distinct, well-defined oviposition areas in nests of the primitively eusocial wasp Polistes versicolor suggests the presence of multiple egg-layers and territorial behaviors. Electrophoretic analysis of enzyme loci in pupae from 35 colonies revealed an average observed heterozygosity of 0.10 and the existence of private polymorphisms, thereby indicating a low dispersion in this species. No evidence of diploid males was found. Phenotypic segregation analysis revealed the presence of more than one egg-laying female in 15 out of 35 colonies, as well as spatially preferential oviposition in 2 out of 13 nests, with distinct oviposition areas. Genetic relatedness estimates for brood were lower than expected for haplodiploid species under monogynous conditions (r = 0.75 for female broods and r = 0.5 for male in 4 of those 13 nests, thereby inferring complex sociogenetic structuring in Polistes versicolor colonies.

Hypersensitivity reactions to hymenoptera venom are infrequent in paediatric patients. A study was made to determine the incidence of this pathology in children, based on an epidemiological survey targeted to all members of the SEICAP (Sociedad Española de Inmunología Clínica y Alergia Pediátrica/Spanish Society of Paediatric Clinical Immunology and Allergy), and designed to collect the data on patients under 17 years of age diagnosed with hymenoptera venom allergy. The data corresponding to 175 patients (135 males) were collected. The mean age was 9.9 ± 3.6 years. Seventeen percent (32 patients) were the offspring of beekeepers, and 68.9% had experienced previous stings. The causal insect was Apis melifera, implicated in 55 cases, followed by Polistes dominulus (33 cases). In 151 patients (83.9%) the condition consisted of a local reaction. The most frequent systemic response was urticaria and angio-oedema. Fourteen patients suffered anaphylactic shock. The diagnosis was based on skin test (intradermal and prick) and/or specific IgE testing. Three treatment categories were established: (a) prevention and educational measures; (b) symptomatic treatment with oral antihistamines as well as self-injectable adrenalin; and (c) immunotherapy. In this context, 135 patients underwent immunotherapy with a mean duration of 3.5 ± 1.7 years (range 2-5 years) - with excellent tolerance. The starting regimen was predominantly conventional (92 patients). The results of this survey show hypersensitivity reactions to hymenoptera venom to be infrequent in paediatrics, though with a strong impact upon patient quality of life. Copyright © 2009 SEICAP.

In the few studies available, the risk of developing systemic reactions (SR) to hymenoptera stings in patients with previous large local reactions (LLRs) to stings ranges from 0 to 7 %. We evaluated both retrospectively and prospectively the risk of SRs in patients with LLRs to stings. An overall number of 477 patients, 396 with an SR as the first manifestation of allergy and 81 with a history of only LLRs after hymenoptera stings, were included in the study. All patients had clinical history and allergy testing (skin tests and/or specific IgE) indicative of allergy to venom of only one kind of Hymenoptera. Of the 81 patient with LLRs, 53 were followed-up for 3 years by annual control visits, while the 396 patients with SR were evaluated retrospectively. Among the 396 patients with an SR, only 17 (4.2 %) had had a previous LLR as debut of allergy, after an history of normal local reactions to Hymenoptera stings. All the 81 patients with a history of only LLRs had previously had at least two LLRs, with an overall number of 238 stings and no SR. Among the 53 patients who were prospectively evaluated we found that 31 of them (58.3 %) were restung by the same type of insect, with an overall number of 59 stings, presenting only LLRs and no SR. Our findings confirm that patients with repeated LLRs to stings had no risk of SR, while a single LLR does not exclude such risk. This has to be considered in the management of patients with LLRs.

Accelerated evolution of mitochondrial but not nuclear genomes of Hymenoptera: new evidence from crabronid wasps.

Directory of Open Access Journals (Sweden)

Martin Kaltenpoth

Full Text Available Mitochondrial genes in animals are especially useful as molecular markers for the reconstruction of phylogenies among closely related taxa, due to the generally high substitution rates. Several insect orders, notably Hymenoptera and Phthiraptera, show exceptionally high rates of mitochondrial molecular evolution, which has been attributed to the parasitic lifestyle of current or ancestral members of these taxa. Parasitism has been hypothesized to entail frequent population bottlenecks that increase rates of molecular evolution by reducing the efficiency of purifying selection. This effect should result in elevated substitution rates of both nuclear and mitochondrial genes, but to date no extensive comparative study has tested this hypothesis in insects. Here we report the mitochondrial genome of a crabronid wasp, the European beewolf (Philanthus triangulum, Hymenoptera, Crabronidae, and we use it to compare evolutionary rates among the four largest holometabolous insect orders (Coleoptera, Diptera, Hymenoptera, Lepidoptera based on phylogenies reconstructed with whole mitochondrial genomes as well as four single-copy nuclear genes (18S rRNA, arginine kinase, wingless, phosphoenolpyruvate carboxykinase. The mt-genome of P. triangulum is 16,029 bp in size with a mean A+T content of 83.6%, and it encodes the 37 genes typically found in arthropod mt genomes (13 protein-coding, 22 tRNA, and two rRNA genes. Five translocations of tRNA genes were discovered relative to the putative ancestral genome arrangement in insects, and the unusual start codon TTG was predicted for cox2. Phylogenetic analyses revealed significantly longer branches leading to the apocritan Hymenoptera as well as the Orussoidea, to a lesser extent the Cephoidea, and, possibly, the Tenthredinoidea than any of the other holometabolous insect orders for all mitochondrial but none of the four nuclear genes tested. Thus, our results suggest that the ancestral parasitic lifestyle of

Single locus complementary sex determination in Hymenoptera: an "unintelligent" design?

Directory of Open Access Journals (Sweden)

Driessen Gerard

2006-01-01

Full Text Available Abstract The haplodiploid sex determining mechanism in Hymenoptera (males are haploid, females are diploid has played an important role in the evolution of this insect order. In Hymenoptera sex is usually determined by a single locus, heterozygotes are female and hemizygotes are male. Under inbreeding, homozygous diploid and sterile males occur which form a genetic burden for a population. We review life history and genetical traits that may overcome the disadvantages of single locus complementary sex determination (sl-CSD. Behavioural adaptations to avoid matings between relatives include active dispersal from natal patches and mating preferences for non-relatives. In non-social species, temporal and spatial segregation of male and female offspring reduces the burden of sl-CSD. In social species, diploid males are produced at the expense of workers and female reproductives. In some social species, diploid males and diploid male producing queens are killed by workers. Diploid male production may have played a role in the evolution or maintenance of polygyny (multiple queens and polyandry (multiple mating. Some forms of thelytoky (parthenogenetic female production increase homozygosity and are therefore incompatible with sl-CSD. We discuss a number of hypothetical adaptations to sl-CSD which should be considered in future studies of this insect order.

Comparative mitogenomics of Braconidae (Insecta: Hymenoptera) and the phylogenetic utility of mitochondrial genomes with special reference to Holometabolous insects

Science.gov (United States)

2010-01-01

Background Animal mitochondrial genomes are potential models for molecular evolution and markers for phylogenetic and population studies. Previous research has shown interesting features in hymenopteran mitochondrial genomes. Here, we conducted a comparative study of mitochondrial genomes of the family Braconidae, one of the largest families of Hymenoptera, and assessed the utility of mitochondrial genomic data for phylogenetic inference at three different hierarchical levels, i.e., Braconidae, Hymenoptera, and Holometabola. Results Seven mitochondrial genomes from seven subfamilies of Braconidae were sequenced. Three of the four sequenced A+T-rich regions are shown to be inverted. Furthermore, all species showed reversal of strand asymmetry, suggesting that inversion of the A+T-rich region might be a synapomorphy of the Braconidae. Gene rearrangement events occurred in all braconid species, but gene rearrangement rates were not taxonomically correlated. Most rearranged genes were tRNAs, except those of Cotesia vestalis, in which 13 protein-coding genes and 14 tRNA genes changed positions or/and directions through three kinds of gene rearrangement events. Remote inversion is posited to be the result of two independent recombination events. Evolutionary rates were lower in species of the cyclostome group than those of noncyclostomes. Phylogenetic analyses based on complete mitochondrial genomes and secondary structure of rrnS supported a sister-group relationship between Aphidiinae and cyclostomes. Many well accepted relationships within Hymenoptera, such as paraphyly of Symphyta and Evaniomorpha, a sister-group relationship between Orussoidea and Apocrita, and monophyly of Proctotrupomorpha, Ichneumonoidea and Aculeata were robustly confirmed. New hypotheses, such as a sister-group relationship between Evanioidea and Aculeata, were generated. Among holometabolous insects, Hymenoptera was shown to be the sister to all other orders.

The baseline blood levels of MC markers were significantly higher, while urinary concentration of 9α,11β-PGF2 was significantly lower in the whole group of venom-sensitized children compared to controls. Severity of SR showed negative correlation with urinary PGD[sub]2[/sub] metabolites, while positive with plasma 9α,11β-PGF2 and BST concentration The highest sensitivity was obtained for plasma 9α,11β-PGF2 whereas the highest specificity for urinary PGD-M. conclusions. In children with IgE-mediated SR to Hymenoptera stings, elevation of baseline values of PGD2 metabolites in blood is accompanied by decreased excretion of its urinary metabolites. Assessment of stable PGD[sub]2 [/sub] metabolites might serve as an independent MC marker to identify allergic children. There is an association between urinary PGD[sub]2[/sub] metabolites and severity of the SR to Hymenoptera stings.

Soares, E R P; Torres, V O; Antonialli-Junior, W F

2014-12-01

In the subfamily Polistinae, caste dimorphism is not pronounced and differences among females are primarily physiological and behavioral. We investigated factors that indicate the reproductive status in females of Polistes ferreri Saussure. We analyzed females from nine colonies and evaluated morphometric parameters, ovarian development, occurrence of insemination, relative age, and cuticular chemical profile. The colony females showed three kinds of ovarian development: type A, filamentous ovarioles; type B, ovarioles containing partially developed oocytes; and type C, long and well-developed ovarioles containing two or more mature oocytes. The stepwise discriminant analysis of the cuticular chemical profile showed that it was possible to distinguish the three groups of females: workers 1, workers 2, and queens. However, the stepwise discriminant analysis of the morphological differences did not show significant differences among these groups. The queens were among the older females in the colony and were always inseminated, while the age of the workers varied according to the stage of colony development.

Nineteen compounds were evaluated in combination with a solution of acetic acid as baits for trapping the German yellowjacket, Vespula germanica (F.), the western yellowjacket Vespula pensylvanica (Sausssure), and the golden paper wasp Polistes aurifer Saussure. Compounds with three to six carbon chains or branched chains and with a hydroxy functional group were selected for testing based on their similarity to isobutanol. They were compared with isobutanol with acetic acid, which is a known wasp attractant. None of the compounds tested were superior to isobutanol when presented with acetic acid as a lure for these species of wasps. However, traps baited with either the S-(-)- or the racemic mixture of 2-methyl-1-butanol in combination with acetic acid captured similar numbers of both species of yellowjackets, compared with isobutanol with acetic acid. Polistes aurifer responded strongly to the S-(-)-enantiomer and to the racemic mixture of 2-methyl-1-butanol with acetic acid and not to the R-(+)-enantiomer with acetic acid.

Full Text Available Among the wasps, the Masarinae are a peculiar subfamily. It is the only group of wasps that provisions brood cells with pollen and nectar. The studied species Trimeria howardi Bertoni, 1911, was until recently abundant in Ribeirão Preto, São Paulo, southeastern Brazil. This paper deals with plant species visited by T. howardi, in relation to the species’ annual cycle of activity, based on periods of nest foundation, flight activity, and development stages of immatures present in the cells. During the study period (five years T. howardi visited four species of plants in two botanical families: Bidens pilosa L.(Asteraceae; Xanthium spinosum L. (Asteraceae; Stylosanthes guianensis (Aulb. Sw. (Leguminosae, and Zornia diphylla (L. Pers. (Leguminosae. Based on the number of visited families, T. howardi can be considered a narrow polylectic species. In general, the species annual activity cycle consists of three phases: Active phase: January to July; Inactive phase: August - September; Active phase: October to December. The annual cycle is bivoltine or multivoltine and the diapause is facultative, because it occurs in a single generation during the year.

Sensitization to the Hymenoptera venom is one of the main causes of anaphylaxis in Poland. Venom immunotherapy is the only effective treatment in such cases. Comprehensive patient care includes also education. The aim of our study was to assess the state of knowledge and to evaluate the quality of life and the anxiety level in patients allergic to the Hymenoptera venom after anaphylactic reaction. The survey was carried out in the period of the insects flight in 61 adult subjects (35 wasp and 26 bee allergic), using a validated Vespid Allergy Quality of Life Questionnaire (VQLQ), Hospital Anxiety and Depression Scale, and subjective assessment of anxiety level. The majority of respondents received venom immunotherapy. Sensitized to the wasp venom had significantly impaired quality of life (VQLQ score) as compared to the bee venom allergic (p = 0.014). The intensity of anxiety decreased with the duration of immunotherapy (p = 0.01). The majority of subjects knew how to recognize and treat anaphylaxis, but only 8% employed an identification card and about 50% implemented rules of the pre-exposition prophylaxis. History of a severe anaphylaxis to the Hymenoptera venom affected the quality of life. Venom immunotherapy reduced anxiety. We hope that presented surveys and their results might be useful in qualifying for immunotherapy in clinically uncertain cases.

Full Text Available Polybia scutellaris (White, 1841 is a social wasp of biological interest for its role as pollinator and maybe as biological control agent of sanitary and agricultural pests. This study examines the digestive tract contents of the larvae of P. scutellaris from four nests in Magdalena (Buenos Aires province, Argentina. Contents included both animal (arthropod parts and plant (pollen, leaf and fruit epidermis parts. The pollen content analysis showed that the wasps visited 19 different taxa of plants during the last active period of the colony before the nests had been collected. The range of sources used by P. scutellaris allows us characterizing the species as a generalist flower visitor. Wasps visited both native and exotic plants located nearby the nest. Most of the epidermal plant remains found in the larval digestive tract belonged to Malvaceae, a family not exploited by the studied colonies as pollen source.Polybia scutellaris (White, 1841 é uma vespa social de interesse biológico devido ao seu papel como polinizador e possível agente de controle biológico de pragas sanitárias e agrícolas. O presente estudo analisou o conteúdo do trato digestivo de larvas de P. scutellaris de quatros ninhos em Magdalena (província de Buenos Aires, Argentina. O conteúdo inclui restos animais (partes de artrópodos e vegetais (pólen, epiderme de folhas e frutos. A análise do conteúdo polínico mostrou que as vespas visitaram 19 táxons durante o último período ativo da colônia antes dos ninhos serem coletados. A diversidade de recursos utilizados por P. scutellaris permite caracterizá-la como um visitante generalista de flores. As vespas visitaram plantas nativas e exóticas localizados nas proximidades do ninho. A maioria dos restos de epiderme encontradas no trato digestivo das larvas pertence às Malvaceae, uma família não explorada pelas colônias estudadas como fonte de pólen.

Full Text Available Diversity and aspects of the ecology of social wasps (Vespidae, Polistinae in Central Amazonian "terra firme" forest. The knowledge of social wasp richness and biology in the Amazonian region is considered insufficient. Although the Amazonas state is the largest in the region, until now only two brief surveys were conducted there. Considering that the systematic inventory of an area is the first step towards its conservation and wise use, this study presents faunal data on social wasp diversity in a 25 km² area of "terra firme" (upland forest at the Ducke Reserve, Manaus, Amazonas, Brazil. Wasps were collected in the understory, following a protocol of three collectors walking along 60 trails 1,000 m in extension for 16 days between August and October 2010. Methods used were active search of individuals with entomological nets and nest collecting. Fifty-eight species of social wasps, allocated in 13 genera, were recorded; 67% of the collected species belong to Polybia, Agelaia and Mischocyttarus; other genera were represented by only four species or less. The most frequent species in active searches were Agelaia fulvofasciata (DeGeer, 1773, Agelaia testacea (Fabricius, 1804 and Angiopolybia pallens (Lepeletier, 1836. Twelve species were collected in nests. Prior to this study, 65 Polistinae species were deposited at the INPA Collection. Collecting in the study grid, an area not previously sampled for wasps, resulted in an increase of 25% species, and species richness was 86. According to the results, there is evidence that the diversity of social wasps at the Ducke Reserve is even higher, making it one of the richest areas in the Brazilian Amazonia.

Genes underlying reproductive division of labor in termites, with comparisons to social Hymenoptera

Directory of Open Access Journals (Sweden)

Judith eKorb

2016-04-01

Full Text Available All social insects are characterized by a reproductive division of labor. Within a colony only a few individuals reproduce (queens and in termites, also a king while the large majority (workers and soldiers forgo reproduction, at least temporarily. The evolution of such reproductive altruism can ultimately be explained by inclusive fitness theory. Here, I will review the proximate genetic mechanisms underlying this altruism in termites. As social cockroaches they evolved eusociality independently from the social Hymenoptera, which makes them interesting test cases to look for common underlying mechanisms of eusociality and lineage specific idiosyncrasies. First, I will provide a summary of the genes and their function that have been identified to underlie reproductive division of labor - so called 'queen genes,' - in the drywood termite Cryptotermes secundus, an emerging model to study termite social evolution. Second, I outline how widespread these queen genes are across the termite phylogeny, using also evidence from recent genome analyses. I will provide hypotheses about the evolutionary origin of these queen genes, aiming to link proximate mechanisms with ultimate functions. Finally, I will draw comparisons to social Hymenoptera to indicate potential common underpinnings that warrant further testing.

Neurology at Escola Paulista de Medicina (1933-1995). From Fausto Guerner to José Geraldo Camargo Lima.

Science.gov (United States)

Ferraz, Henrique Ballalai; Neves, Afonso Carlos

2015-02-01

Escola Paulista de Medicina (EPM) was founded in 1933 and the first Professor of Neurology was Fausto Guerner, who could not effectively assume the teaching activities due to his premature death in 1938. Professor Guerner had had his neurological training at Paris. Professor Longo was his successor. Longo was one of the founders of Arquivos de Neuro-Psiquiatria the foremost journal of neurosciences in Latin American. Longo died in 1967 and Professor Paulo Pupo succeeded him. Pupo introduced electroencephalography in Brazil. After his death in 1970, Professor Dante Giorgi succeeded him until 1974. Professor José Geraldo Camargo Lima took over the position after Giorgi's death. He created the Neurological Emergency unit, initiated the Post-Graduation in Neurology and divided the Discipline in specialized units. During the 1980's and until his retirement in 1995, EPM had become one of most important centers of Brazil training neurologists and researchers in neurological sciences.

Hymenoptera venoms are known to cause life-threatening IgE-mediated anaphylactic reactions in allergic individuals. Venom immunotherapy is a recommended treatment of insect allergy with still the mechanism not being completely understood. We decided to assess the serum CCL5/RANTES level in patients who experienced severe anaphylactic reaction to Hymenoptera venom and to find out changes in the course of immunotherapy. Twenty patients (9 men, 11 women, mean age: 31.91 ± 7.63 years) with history of anaphylactic reaction after insect sting were included into the study. Diagnosis was made according to sIgE and skin tests. All of them were enrolled into rush venom immunotherapy with bee or wasp venom extracts (Pharmalgen, ALK-Abello, Horsholm, Denmark). Serum levels of CCL5/RANTES were measured using a commercially available ELISA kit (R&D Systems, Minneapolis, MN). CCL5/RANTES serum concentration are higher in insect venom allergic patients than in healthy controls (887.5 ± 322.77 versus 387.27 ± 85.11 pg/ml). Serum concentration of CCL5/RANTES in insect venom allergic patient was significantly reduced in the course of allergen immunotherapy already after 6 days of vaccination (887.5 ± 322.77 versus 567.32 ± 92.16 pg/ml). CCL5/RANTES serum doesn't correlate with specific IgE. Chemokine CCL5/RANTES participates in allergic inflammation induced by Hymenoptera venom allergens. Specific immunotherapy reduces chemokine CCL5/RANTES serum level already after initial days of venom immunotherapy.

The rearranged mitochondrial genome of Leptopilina boulardi (Hymenoptera: Figitidae, a parasitoid wasp of Drosophila

Directory of Open Access Journals (Sweden)

Daniel S. Oliveira

Full Text Available Abstract The partial mitochondrial genome sequence of Leptopilina boulardi (Hymenoptera: Figitidae was characterized. Illumina sequencing was used yielding 35,999,679 reads, from which 102,482 were utilized in the assembly. The length of the sequenced region of this partial mitochondrial genome is 15,417 bp, consisting of 13 protein-coding, two rRNA, and 21tRNA genes (the trnaM failed to be sequenced and a partial A+T-rich region. All protein-coding genes start with ATN codons. Eleven protein-coding genes presented TAA stop codons, whereas ND6 and COII that presented TA, and T nucleotides, respectively. The gene pattern revealed extensive rearrangements compared to the typical pattern generally observed in insects. These rearrangements involve two protein-coding and two ribosomal genes, along with the 16 tRNA genes. This gene order is different from the pattern described for Ibalia leucospoides (Ibaliidae, Cynipoidea, suggesting that this particular gene order can be variable among Cynipoidea superfamily members. A maximum likelihood phylogenetic analysis of the main groups of Apocrita was performed using amino acid sequence of 13 protein-coding genes, showing monophyly for the Cynipoidea superfamily within the Hymenoptera phylogeny.

Solidariedade étnica, poder local e banditismo: uma quadrilha calabresa no oeste paulista, 1895-1898

Directory of Open Access Journals (Sweden)

Monsma Karl

2003-01-01

Full Text Available A história de uma quadrilha de bandidos calabreses no município de São Carlos, oeste paulista, ao final do século XIX permitiu-nos investigar por que o banditismo italiano era raro no Brasil. A quadrilha contou com certa rede de apoio entre calabreses e com o silêncio de outros italianos, seja pela intimidação, seja pela desconfiança que estes nutriam das autoridades brasileiras. Uma epidemia devastadora de febre amarela, que afastou da região grande parte da elite local e debilitou a polícia, garantiu ao bando alguns anos de impunidade. O fato de terem imigrado para a região italianos de várias origens não é suficiente para explicar a raridade do banditismo e do crime organizado entre italianos no Brasil. Dois fatores foram decisivos nesse sentido, ao contrário do que ocorreu na Calábria e nos Estados Unidos: ausência de elites dispostas a proteger bandidos imigrantes e dificuldade para os bandidos corromperem as autoridades locais, especialmente a polícia.

La Villa Matarazzo en la avenida Paulista y Tomaso Buzzi: proyecto y obras (1938-1940

2013-12-01

Full Text Available The demolition of the Matarazzo mansion on Avenida Paulista is an example of a lack of awareness and coordination of cultural heritage preservation mechanisms, to a certain extent attributable to insufficient research on buildings of a great architectural worth. In a metropolis like São Paulo that is so rich in 20th century architectural gestures and symbols, this question could appear to be of minor importance. Nevertheless, and despite the everyday loss of architectural objects of great cultural value, it is important to gain better familiarity with them in order to avoid the complete disappearance of their memory after their physical destruction. This article discusses the design process of the mansion renovation between 1938 and 1940, which gave us the image of the building that lasted until its demolition. The study puts this architectural work into context and removes any doubt about Tomaso Buzzi’s authorship of this project. Buzzi is an architect who has only recently become the focus of intense study in Italy and hopefully will be better known in Brazil.

Epidemiology of allergic reactions to hymenoptera stings in Irish school children.

LENUS (Irish Health Repository)

Jennings, Aisling

2010-12-01

The aim of this was to study generate the first epidemiological data regarding the prevalence of hymenoptera allergy among school children in Ireland. Questionnaires, including six sting-specific questions (1), were distributed to the parents of primary school children aged 6-8 and 11-13, divided equally between rural and urban backgrounds. From 110 schools, 4112 questionnaires were returned. A total of 1544 (37.5%) children had been stung in their lifetime. Among the total, 5.8% of children stung experienced a large local reaction, 3.4% had a mild (cutaneous) systemic reaction (MSR) and 0.8% experienced a moderate\\/severe systemic reaction (SSR); these figures respectively represent 2.2%, 1.3% and 0.2% of the total study group. On logistic regression analysis, older children and rural children were at a higher risk of being stung (OR 1.7; 95% CI 1.4-2.; OR 1.6; 95% CI 1.4-1.8 respectively). Rural dwellers and asthma sufferers were more likely to experience an SSR (OR 4.3; 95% CI 1.4-13.5 and OR 2.8; 95% CI 1.8-4.3, respectively). Hymenoptera stings are more common in rural than urban dwelling Irish children. Asthma imparted a greater risk of SSR in this study population. Severe reactions are unusual overall, occurring in <1% of those stung, a lower prevalence than in Israeli teenagers but in keeping with other European reports relating to young children.

Full Text Available Despite measures adopted to control American visceral leishmaniasis (AVL, the disease is spreading in a fast and worrying way throughout western São Paulo state. The aim of this work was to study the variables involved in the disease cycle as well as the effectiveness of controlling measures. The study was carried out in the microregion of Dracena, which is composed of twelve cities and belongs to Alta Paulista, a region of western São Paulo. The necessary data were provided by the Superintendence for Endemic Disease Control and Adolfo Lutz Institute, Regional Laboratory of Presidente Prudente. From August 2005 to January 2008, the following factors were observed: detection of phlebotomine sandflies in the cities and periods in which dogs or humans were diagnosed; number of human deaths; prevalence of suspected dogs tested by serology; percentage of euthanasia in suspected dogs; a possible correlation between positive dogs and cases of the disease in humans; and the disease prevalence among municipalities from the studied region. It was verified that, despite the strategies adopted in Dracena microregion to control AVL, the disease continues to rise. Thus, some procedures of the AVL Monitoring and Control Program should be reviewed, to grant the initiative more credibility and effectiveness.

A Total-Evidence Approach to Dating with Fossils, Applied to the Early Radiation of the Hymenoptera

Abstract Phylogenies are usually dated by calibrating interior nodes against the fossil record. This relies on indirect methods that, in the worst case, misrepresent the fossil information. Here, we contrast such node dating with an approach that includes fossils along with the extant taxa in a Bayesian total-evidence analysis. As a test case, we focus on the early radiation of the Hymenoptera, mostly documented by poorly preserved impression fossils that are difficult to place phylogenetically. Specifically, we compare node dating using nine calibration points derived from the fossil record with total-evidence dating based on 343 morphological characters scored for 45 fossil (4--20 complete) and 68 extant taxa. In both cases we use molecular data from seven markers (∼5 kb) for the extant taxa. Because it is difficult to model speciation, extinction, sampling, and fossil preservation realistically, we develop a simple uniform prior for clock trees with fossils, and we use relaxed clock models to accommodate rate variation across the tree. Despite considerable uncertainty in the placement of most fossils, we find that they contribute significantly to the estimation of divergence times in the total-evidence analysis. In particular, the posterior distributions on divergence times are less sensitive to prior assumptions and tend to be more precise than in node dating. The total-evidence analysis also shows that four of the seven Hymenoptera calibration points used in node dating are likely to be based on erroneous or doubtful assumptions about the fossil placement. With respect to the early radiation of Hymenoptera, our results suggest that the crown group dates back to the Carboniferous, ∼309 Ma (95% interval: 291--347 Ma), and diversified into major extant lineages much earlier than previously thought, well before the Triassic.

2010-01-01

Full Text Available Four colonies of the stingless bee Partamona cupira (Hymenoptera: Apidae were cytogenetically analyzed using conventional staining and the fluorochromes CMA3 e DAPI. The females have 2n = 34 chromosomes (2K=32+2. Some females, however, presented an additional large B acrocentric chromosome, to a total of 2n = 35. Chromosome B and the chromosomal pairs 2, 9 and 10 showed CMA3+ bands, indicating an excess of CG base-pairs. A clear association was verified between the P. helleri B chromosome SCAR marker and the presence of a B chromosome in P. cupira. The data obtained suggests that B chromosomes in P. helleri and P. cupira share a common origin.

The invasion, provenance and diversity of Vespa velutina Lepeletier (Hymenoptera: Vespidae in Great Britain.

Directory of Open Access Journals (Sweden)

Giles E Budge

Full Text Available The yellow-legged or Asian hornet (Vespa velutina colour form nigrithorax was introduced into France from China over a decade ago. Vespa velutina has since spread rapidly across Europe, facilitated by suitable climatic conditions and the ability of a single nest to disperse many mated queens over a large area. Yellow-legged hornets are a major concern because of the potential impact they have on populations of many beneficial pollinators, most notably the western honey bee (Apis mellifera, which shows no effective defensive behaviours against this exotic predator. Here, we present the first report of this species in Great Britain. Actively foraging hornets were detected at two locations, the first around a single nest in Gloucestershire, and the second a single hornet trapped 54 km away in Somerset. The foraging activity observed in Gloucestershire was largely restricted to within 700 m of a single nest, suggesting highly localised movements. Genetic analyses of individuals from the Gloucestershire nest and the single hornet from Somerset suggest that these incursions represent an expansion of the European population, rather than a second incursion from Asia. The founding queen of the Gloucestershire nest mated with a single male, suggesting that sexual reproduction may have occurred in an area of low nest density. Whilst the nest contained diploid adult males, haploid 'true' males were only present at the egg stage, indicating that the nest was detected and removed before the production of queens. Members of the public reported additional dead hornets associated with camping equipment recently returned from France and imported timber products, highlighting possible pathways of incursion. The utility of microsatellites to inform surveillance during an incursion and the challenge of achieving eradication of this damaging pest are discussed.

Analysis of digestive tract content of the larvae of Polybia scutellaris (White (Hymenoptera, Vespidae

2011-06-01

Full Text Available Polybia scutellaris (White, 1841 is a social wasp of biological interest for its role as pollinator and maybe as biological control agent of sanitary and agricultural pests. This study examines the digestive tract contents of the larvae of P. scutellaris from four nests in Magdalena (Buenos Aires province, Argentina. Contents included both animal (arthropod parts and plant (pollen, leaf and fruit epidermis parts. The pollen content analysis showed that the wasps visited 19 different taxa of plants during the last active period of the colony before the nests had been collected. The range of sources used by P. scutellaris allows us characterizing the species as a generalist flower visitor. Wasps visited both native and exotic plants located nearby the nest. Most of the epidermal plant remains found in the larval digestive tract belonged to Malvaceae, a family not exploited by the studied colonies as pollen source.

Katja Seltmann

2012-05-01

Full Text Available Hymenoptera exhibit an incredible diversity of phenotypes, the result of ~240 million years of evolution and the primary subject of more than 250 years of research. Here we describe the history, development, and utility of the Hymenoptera Anatomy Ontology (HAO and its associated applications. These resources are designed to facilitate accessible and extensible research on hymenopteran phenotypes. Outreach with the hymenopterist community is of utmost importance to the HAO project, and this paper is a direct response to questions that arised from project workshops. In a concerted attempt to surmount barriers of understanding, especially regarding the format, utility, and development of the HAO, we discuss the roles of homology, “preferred terms”, and “structural equivalency”. We also outline the use of Universal Resource Identifiers (URIs and posit that they are a key element necessary for increasing the objectivity and repeatability of science that references hymenopteran anatomy. Pragmatically, we detail a mechanism (the “URI table” by which authors can use URIs to link their published text to the HAO, and we describe an associated tool (the “Analyzer” to derive these tables. These tools, and others, are available through the HAO Portal website (http://portal.hymao.org. We conclude by discussing the future of the HAO with respect to digital publication, cross-taxon ontology alignment, the advent of semantic phenotypes, and community-based curation.

Full Text Available Abstract Background The order Hymenoptera (bees, ants, wasps, sawflies contains about eight percent of all described species, but no analytical studies have addressed the origins of this richness at family-level or above. To investigate which major subtaxa experienced significant shifts in diversification, we assembled a family-level phylogeny of the Hymenoptera using supertree methods. We used sister-group species-richness comparisons to infer the phylogenetic position of shifts in diversification. Results The supertrees most supported by the underlying input trees are produced using matrix representation with compatibility (MRC (from an all-in and a compartmentalised analysis. Whilst relationships at the tips of the tree tend to be well supported, those along the backbone of the tree (e.g. between Parasitica superfamilies are generally not. Ten significant shifts in diversification (six positive and four negative are found common to both MRC supertrees. The Apocrita (wasps, ants, bees experienced a positive shift at their origin accounting for approximately 4,000 species. Within Apocrita other positive shifts include the Vespoidea (vespoid wasps/ants containing 24,000 spp., Anthophila + Sphecidae (bees/thread-waisted wasps; 22,000 spp., Bethylidae + Chrysididae (bethylid/cuckoo wasps; 5,200 spp., Dryinidae (dryinid wasps; 1,100 spp., and Proctotrupidae (proctotrupid wasps; 310 spp.. Four relatively species-poor families (Stenotritidae, Anaxyelidae, Blasticotomidae, Xyelidae have undergone negative shifts. There are some two-way shifts in diversification where sister taxa have undergone shifts in opposite directions. Conclusions Our results suggest that numerous phylogenetically distinctive radiations contribute to the richness of large clades. They also suggest that evolutionary events restricting the subsequent richness of large clades are common. Problematic phylogenetic issues in the Hymenoptera are identified, relating especially to

Observa-se um efeito positivo e significativo do Programa sobre a arrecadação real do setor terciário entre 5% e 10% comparativamente aos outros Estados do Brasil. Não é encontrado efeito robusto sobre a arrecadação real total, nem efeitos não lineares do Programa. Quando a análise é restrita somente ao Estado de São Paulo, a evidência sugere que o Programa não produziu efeitos diferenciados entre os setores. Contudo, quando o aumento de arrecadação do setor terciário é comparado com a estimativa dos prêmios concedidos tem-se um aumento de no máximo 2% da arrecadação média do setor terciário para São Paulo. Conclui-se, então, que o impacto do Programa parece ter sido limitado. É preciso levar em conta que a análise feita é bastante agregada. Uma análise mais desagregada permitiria uma melhor identificação do efeito da Nota Fiscal Paulista sobre setores específicos, mas infelizmente dados desta natureza não estão disponíveis.

Full Text Available A higher-level classification of bees, in which the entire group is treated as a single family - the Apidae - is advocated here. A total of seven subfamilies, 51 tribes and 27 subtribes are recognized. These subfamilies correspond to the families adopted in the traditional classification. Although the proposed changes do not involve any major rearrangement, basically only changing the rank given to the main groups, the new system makes the classification of bees more consistent with that adopted for other major groups of aculeate Hymenoptera. It also departs from the 19th century practice, perpetuated in the traditional classification, of giving family-status to the main groups of bees. A correspondence table associating the taxon names used in the current traditional classification with those of the revised classification is presented. Scrapterini new tribe (type-genus Scrapter Lepeletier & Serville is proposed to accommodate the southern African genus Scrapter.Apresenta-se uma classificação para as abelhas em que o todo o grupo é tratado como uma única família - Apidae.

2017-01-01

The ability of aculeate Hymenoptera to utilize wetlands is poorly understood, and descriptions of their nests and developmental stages are largely absent. Here we present results based on our survey of hymenopterans using galls induced by Lipara spp. flies on common reed Phragmites australis in the years 2015-2016. We studied 20,704 galls, of which 9,446 were longitudinally cut and the brood from them reared in the laboratory, while the remaining 11,258 galls reared in rearing bags also in laboratory conditions. We recorded eight species that were previously not known to nest in reed galls: cuckoo wasps Chrysis rutilans and Trichrysis pumilionis, solitary wasps Stenodynerus chevrieranus and Stenodynerus clypeopictus, and bees Pseudoanthidium tenellum, Stelis punctulatissima, Hylaeus communis and Hylaeus confusus. Forty five species of Hymenoptera: Aculeata are known to be associated with reed galls, of which 36 make their nests there, and the other are six parasitoids of the family Chrysididae and three cuckoo bees of the genus Stelis. Of these species, Pemphredon fabricii and in southern Europe also Heriades rubicola are very common in reed galls, followed by Hylaeus pectoralis and two species of the genus Trypoxylon. We also found new host-parasite associations: Chrysis angustula in nests of Pemphredon fabricii, Chrysis rutilans in nests of Stenodynerus clypeopictus, Trichrysis pumilionis in nests of Trypoxylon deceptorium, and Stelis breviuscula in nests of Heriades rubicola. We provide new descriptions of the nests of seven species nesting in reed galls and morphology of mature larvae of eight species nesting in reed galls and two parasitoids and one nest cleptoparasite. The larvae are usually very similar to those of related species but possess characteristics that make them easy to distinguish from related species. Our results show that common reeds are not only expansive and harmful, but very important for many insect species associated with habitats

The wasp larva's last supper: 100 million years of evolutionary stasis in the larval development of rhopalosomatid wasps (Hymenoptera: Rhopalosomatidae

Directory of Open Access Journals (Sweden)

V. Lohrmann

2017-08-01

Full Text Available Rhopalosomatidae are an unusual family of wasps (Hymenoptera: Aculeata comprising less than 100 species found in the tropics and subtropics of all continents except Europe and Antarctica. Whereas some species resemble nocturnal Ichneumonidae, others might be mistaken for spider wasps or different groups of brachypterous Hymenoptera. Despite their varied morphology, all members of the family supposedly develop as larval ectoparasitoids of crickets (Orthoptera: Grylloidea. Here, we report on the first record of a fossil rhopalosomatid larva which was discovered in mid-Cretaceous amber from northern Myanmar (Burma. The larva is attached to the lateral side of a cricket between the metafemur and the abdomen, impacting the natural position of the hind leg, exactly as documented for modern species. Additionally, the larval gestalt is strikingly similar to those of extant forms. These observations imply that this behavioral specialization, e.g., host association and positioning on host, likely evolved in the stem of the family at least 100 million years ago.

Foraging behaviour of the exotic wasp Vespula germanica (Hymenoptera: Vespidae) on a native caterpillar defoliator.

Science.gov (United States)

Pietrantuono, A L; Moreyra, S; Lozada, M

2017-09-19

Vespula germanica is a social wasp and an opportunistic predator. While foraging, these wasps learn and integrate different kinds of cues. They have successfully invaded many parts of the world, including native Nothofagus and Lophozonia forests located in the Andean-Patagonian region, where they forage on native arthropods. Perzelia arda, a lepidopteron defoliator of Lophozonia obliqua, uses the foliage to hide in and feed on. The purpose of this work is to study whether V. germanica use olfactory cues when foraging on P. arda. To do this, we used a Y-tube olfactometer and established three treatments to compare pairs of all combinations of stimuli (larvae, leaves with larval traces, and leaves without larval traces) and controls. Data were analysed via two developed models that showed decisions made by V. germanica and allowed to establish a scale of preferences between the stimuli. The analysis demonstrates that V. germanica wasps choose P. arda as larval prey and are capable of discriminating between the offered stimuli (deviance information criterion (DIC) null model = 873.97; DIC simple model = 84.5, n = 152). According to the preference scale, V. germanica preferred leaves with traces of larvae, suggesting its ability to associate these traces with the presence of the prey. This may be because, under natural conditions, larvae are never exposed outside their shelters of leaves and therefore V. germanica uses indirect signals. The presence of V. germanica foraging on P. arda highlights the flexible foraging behaviour of this wasp which may also act as a positive biological control, reducing lepidopteran populations.

Mouthpart dimorphism in male and female wasps of Vespula vulgaris and Vespula germanica (Vespidae, Hymenoptera

Directory of Open Access Journals (Sweden)

Bianca Baranek

2018-03-01

Full Text Available Social wasps perform a variety of tasks with their mouthparts. Female workers use them to feed on carbohydrate-rich fluids, to build nests by collecting wood fibers and forming paper, to hunt and manipulate insect prey for feeding larvae as well as for brood care. Since male wasps neither feed on insects nor participate in nest building, sex-specific differences in mouthpart morphology are expected. Despite these different applications, general mouthpart morphology of male and female wasps from the genus Vespula was similar. However, males possessed significantly shorter mandibles with fewer teeth than females. Furthermore, the adductor muscles of the mandibles were distinctly smaller in males than in females. Male wasps showed a higher number of sensilla on the mandibles and the labial palpi. Mouthpart dimorphism and functional morphology of fluid uptake are discussed.

Nesting biology of Paravespa rex (von Schulthess 1924) (Hymenoptera: Vespidae: Eumeninae) in the Crimea, Ukraine.

Science.gov (United States)

Fateryga, Alexander V; Ivanov, Sergey P

2013-01-01

Paravespa rex is the only species of the wasp genus Paravespa that occurs in Europe. Females of this species nest in clay loam soil of proluvial terraces and deluvial aprons of badlands. The nests are vertical burrows 10-12 cm deep, surmounted by turrets of two distinct architectural forms: funnel-shaped and curved. The nests contain 1-3 vertical cells (mean-1.9) not different from the other parts of nest burrow. An egg is laid onto the bottom of the cell without attaching; it stands vertically via the moist adhesive surface of the bottom and then with the help of the position of the first prey, which is laid around the egg. The species is univoltine; prepupae hibernate in the cocoon for one or several years. Females hunt for caterpillars of two species of the noctuid genus Heliotis; 3-7 caterpillars (mean-3.7) are stored per cell. Adult feeding is recorded on flowers of Thymus tauricus. Males look for females at their water-collecting sites. Only a third of the cells are successful; the other ones are damaged by rain and the gold wasp, Chrysis valesiana, parasitizing in the nests. Nest-building and hunting activity of the species is described with the duration of certain nesting acts. Nesting biology of Paravespa species, rarity of P. rex, turret function, egg position, and measures for species conservation are discussed.

Full Text Available Ikh Nart Nature Reserve remains poorly studied for invertebrates, especially for vespid wasps. A total of 14 vespid species belonging to seven genera of the subfamily Eumeninae were recorded from diff erent habitats (rocky outcrops, springs, tall vegetation habitats, shrub-lands and short grass steppes in the nature reserve during three-year studies (2015-2017. These species represent 27 percent of the vespid fauna of the desert-steppe zone of Mongolia. We found the highest species richness in areas where water was available (near springs and wells, and the lowest richness in habitats with tall vegetation. Among the diff erent habitat types, vespid species composition was most similar (91% shared species between rocky outcrops and spring habitats. Six vespid species range from Kazakhstan to Mongolian, and one species is sub-endemic to Mongolia. Availability of water sources and nesting sites were possibly the main factors infl uencing the distribution of vespid wasps. It is necessary to conduct comprehensive research into the insect community of Ikh Nart Nature Reserve.

Case presentation A 39-year old patient was referred for history of multiple miscarriage and a history of insect sting allergy. Four years earlier, she began subcutaneous injection of 100 mcg mixed vespid hymenoptera venom/venom protein every 5–6 weeks. The patient had one livebirth and three first trimester miscarriages. Allergy treatment was maintained for all pregnancies ending in miscarriage, although allergy therapy was discontinued for the pregnancy that resulted in delivery. At our institution ovulation induction incorporated venom immunotherapy (VIT during IVF, with a reduced VIT dose when pregnancy was first identified. Serum IgE was monitored with estradiol during ovulation induction and early pregnancy. Response to controlled ovarian hyperstimulation was favorable while VIT was continued, with retrieval of 12 oocytes. Serum RAST (yellow jacket IgE levels fluctuated in a nonlinear fashion (range 36–54% during gonadotropin therapy and declined after hCG administration. A healthy female infant was delivered at 35 weeks gestation. The patient experienced no untoward effects from any medications during therapy. Conclusion Our case confirms the safety of VIT in pregnancy, and demonstrates RAST IgE can remain

Full Text Available The flower of balsa wood holds about 10 to 15 mL of nectar, which helps attracting pollinating agents, since the genus Ochroma is incapable of self-fertilization. However, a high mortality of bees is observed in these flowers. The present study investigated the frequency and constancy of mortality of the individuals of the familyApidae that fed on nectar from the balsa wood. Data was gathered from June to August 2008, in Lavras – Minas Gerais State, Brazil. In addition, the survival of the Africanized bees that fed on the nectar of this flower was compared to those that fed on 50% aqueous solution of honey. Forty flowers were analyzed, and 949 individuals of the orders Hymenoptera (98.1%, Hemiptera (0.95%, Coleoptera (0.74% and Diptera (0.21% were collected. Most Hymenoptera individuals were bees of the genera Partamona and Trigona (677 individuals, which were considered of constant occurrence. Flowers producing up to 16.7 nectar mL were found. The nectar diet contained 16.44% of total sugar, and resulted in low survival of the bees in laboratory (31.32 . 2.37 hours, compared to a diet of 50% aqueous solution of honey (112.32 .2.03 hours.A flor do pau-de-balsa produz cerca de 10 a 15 mL de néctar, útil na atração de polinizadores, uma vez que o gênero Ochroma é incapaz de fazer autofecundação.

Memory has been little studied in social wasps. Vespula germanica (Fab.) (Hymenoptera: Vespidae) frequently revisits nondepleted food sources, making several trips between the resource and the nest. In this study, we analyzed this relocating behavior in order to evaluate whether this species is capable of remembering an established association after 1 h. To this end, we trained wasps to feed from a certain array. Then it was removed, setting it up again 1 h later, but this time 2 baited feeders were put in place, one at the original feeding site and the other opposite the first. We recorded the proportion of returning foragers, and their choice of feeder, after either 1 or 4 feeding trials. After 1 h, 78% of wasps trained with 4 feeding trials and 65% trained with 1, returned to the experimental area. Furthermore, during the testing phase, wasps trained with 4 feeding trials collected food from the previously learned feeder significantly more frequently than from the nonlearned one (P germanica is capable of remembering an association 1 h after the last associative event, demonstrating that 1 h does not impair memory retention if 4 feeding experiences have occurred. © 2013 Institute of Zoology, Chinese Academy of Sciences.

Checklist of Social Wasps (Vespidae: Polistinae in Two Green Urban Areas in the Municipality of Barra Mansa, Rio de Janeiro, Brazil Abstract. New concepts on city planning and urbanization have progressively encouraged the creation and maintenance of public or private green areas, which are important feeding and shelter zones for several species of social wasps. However, in spite of the sampling effort and representativeness of southeastern Brazil, knowledge of richness and abundance of social wasps in Rio de Janeiro is still poor. The present study aimed at inventorying the fauna of social wasps in urban phytophysiognomies in downtown Barra Mansa, state of Rio de Janeiro, within the campus of Barra Mansa University. We sampled two areas for 12 months - a human-modified grassland and a reforested area, through active search with insect nests, Möericke traps, and aromatic traps. We collected 148 wasps of three tribes, four genera, and 17 species. Through active search we recorded 70.7% of the species sampled. The tribe Epiponini showed the highest species richness, and Polybia chrysothorax Lichtenstein and Polybia erythrothoraxla Richards were recorded for the first time in the state of Rio de Janeiro. In the anthropic field it was observed greater diversity (H’ = 1,890, equitability (J = 0,7605, and minor dominance (D(1/D = 0,2124, while in the reforested area was obtained H’ = 1,582, J = 0,6366 e D(1/D = 0,3465. The configuration and size of the reforested area in the campus Barra Mansa (UBM are insufficient elements to restrict the movement of species or segregate communities when considering the anthropic field, thereby still allowing that species could also be sampled between the areas.

To study the occurrence and types of neoplasms developed by patients who underwent an orthotopic cardiac transplantation under the Program of Cardiac Transplantation of Escola Paulista de Medicina, Federal University of São Paulo. This is an observational study of 106 patients who underwent orthotopic cardiac transplantation from November 1986 to September 2002 and survived at least thirty days following the procedure. The triple immunosuppressive regimen given included cyclosporin A, azathioprine and a corticosteroid agent. Only two patients received OKT3 in addition to the regimen established. Mean follow-up was 61.4 months (ranging from two months to 192 months). Twenty-three patients (21.3%) developed neoplasms--56.5% of these were skin neoplasm, 30.1%, solid tumors, and 13.4% of post-transplant lymphoproliferative disease (PTLD). Mean interval between transplantation and diagnosis of neoplasm was: 54.9 months for skin neoplasm; 24.8 months for solid tumors and 70.3 months for PTLD. Malignant neoplasms are relatively common in the population studied. Skin cancer was the most common type compared to the other types of neoplasms. Solid tumors were more frequently diagnosed than the lymphoproliferative diseases in the population examined.

Full Text Available OBJECTIVE: To analyze mortality due to Hymenoptera stings in Costa Rica during 1985-2006. METHODS: Records of deaths due to Hymenoptera stings in 1985-2006 were retrieved from Instituto Nacional de Estadística y Censos (National Statistics and Census Institute. Mortality rates were calculated on the basis of national population reports, as of 1 July of each year. Information for each case included age, gender, and the province in which the death occurred. In addition, reports of Hymenoptera sting accidents received by the Centro Nacional de Intoxicaciones (National Poison Center, CNI in 1995-2006 were obtained to assess exposure to these insects. RESULTS: Over the 22-year period analyzed, 52 fatalities due to Hymenoptera stings were recorded. Annual mortality rates varied from 0-1.73 per 1 million inhabitants, with a mean of 0.74 (95% confidence interval: 0.46-0.93. The majority of deaths occurred in males (88.5%, representing a male to female ratio of 7.7:1. A predominance of fatalities was observed in the elderly (50 years of age and older, as well as in children less than 10 years of age. The province with the highest mortality rate was Guanacaste. The CNI documented 1 591 reports of Hymenoptera stings (mostly by bees in 1995-2006, resulting in an annual average of 133 cases, with only a slight predominance of males over females (1.4:1. CONCLUSIONS: Stings by Hymenoptera, mostly by bees, constitute a frequent occurrence in Costa Rica that can be life-threatening in a small proportion of cases, most often in males and the elderly. The annual number of fatalities fluctuated from 0-6, averaging 2.4 deaths per year. Awareness should be raised not only among the general population, but also among health care personnel that should consider this risk in the clinical management of patients stung by Hymenoptera.OBJETIVO: Analizar la mortalidad por picaduras de himenópteros en Costa Rica en el período de 1985 a 2006.

Full Text Available On the identity of Melipona torrida Friese (Hymenoptera, Apidae. Melipona marginata var. torrida Friese, 1916, described from three workers putatively collected in Costa Rica, never had its identity properly recognized. Since its original description, no additional specimens have ever been collected in Costa Rica. It is argued here that Melipona torrida was based on mislabeled specimens and corresponds to Melipona marginata obscurior Moure, 1971, a form known only from southern Brazil, Argentina and Paraguay. A lectotype is designated for Melipona torrida and notes on the type material of Melipona marginata obscurior are provided. Other known examples of species described from mislabeled specimens in Friese's Zur Bienenfauna von Costa Rica are discussed. It is pointed out that additional names proposed in this work, based on material from Costa Rica, might turn out to correspond to South American taxa. Also, the date of publication of this Friese's paper is discussed.

Full Text Available A preocupação com a erosão do solo, sobretudo em áreas rurais, vem aumentando em diversos países. Encontra-se a temática em pesquisas divulgadas em periódicos nacionais e internacionais, os quais indicam a influência significativa da ação humana na escala temporal dos fenômenos denudativos. Considerando o tema, o objetivo deste artigo é avaliar essa problemática na bacia do ribeirão Areia Dourada, localizada no município de Marabá Paulista (SP. Por meio do uso de dados advindos de diversos mapeamentos, informações sobre a região foram quantificadas e sistematizadas na forma de gráfico em rede. Assim, buscou-se avaliar a influência dos fatores físicos e da ação humana no desencadeamento e desenvolvimento das formas erosivas, considerando a área de estudo como um exemplo representativo da problemática erosiva no Oeste Paulista. O esquema de gráfico possibilitou aferir um grande volume de informações em um mesmo modelo, de modo a destacar que o uso da terra, sobretudo a pecuária, impacta de forma significativa no desencadeamento dos processos denudativos, indicando o caráter catalisador da ação humana, que generaliza a ação morfodinâmica. Contudo, os dados também demonstram que as formas erosivas só atingem nível de voçorocamento onde as características físicas sugerem maior predisposição a tais processos, como as concavidades das vertentes. Assim, considera-se que o uso do gráfico em rede possibilitou a avaliação das combinações entre as classes temáticas em que o processo erosivo se desenvolve com maior intensidade, bem como a influência da ação humana. Constatou-se que os fenômenos erosivos, muitas vezes, ocorrem em setores cujas características físicas não indicam potencialidade ao seu desenvolvimento, como o surgimento de feições erosivas lineares em setores de topo com energia do relevo fraca. Fatos como este se devem à ação do uso da terra, principalmente, no caso estudado, das

Full Text Available Leaf-litter amount as a factor in the structure of a ponerine ants community (Hymenoptera, Formicidae, Ponerinae in an eastern Amazonian rainforest, Brazil. Leaf-litter may be an important factor in structuring ponerine ant communities (Hymenoptera, Formicidae, Ponerinae in tropical rainforests. We specifically examined how leaf-litter affects the structure of a ponerine ant community in primary Amazonian rainforest sites at the Ferreira Penna Scientific Station, Pará, Brazil. A total of 53 species belonging to eight genera of three ponerine tribes were collected with mini-Winkler extractors. The amount of leaf-litter positively affected the abundance and richness of the ponerine ant community, and also influenced species composition. Nearby samples often had low species similarity, especially when adjacent samples differed in the amount of leaf-litter. Leaf-litter availability in Amazonian primary forests is a key factor for distribution of ground-dwelling ponerine species, even at small scales.

Não é encontrado efeito robusto sobre a arrecadação real total, nem efeitos não lineares do Programa. Quando a análise é restrita somente ao Estado de São Paulo, a evidência sugere que o Programa não produziu efeitos diferenciados entre os setores. Contudo, quando o aumento de arrecadação do setor terciário é comparado com a estimativa dos prêmios concedidos tem-se um aumento de no máximo 2% da arrecadação média do setor terciário para São Paulo. Conclui-se, então, que o impacto do Programa parece ter sido limitado. É preciso levar em conta que a análise feita é bastante agregada. Uma análise mais desagregada permitiria uma melhor identificação do efeito da Nota Fiscal Paulista sobre setores específicos, mas infelizmente dados desta natureza não estão disponíveis.The purpose of this paper is to evaluate the impact of Programa Nota Fiscal Paulista on tax revenue collection by the state of São Paulo.

We do not find a robust effect of the Program neither on total tax collection nor in the other sectors, as well as, evidence ofa non-linear effect in time. When the analysis is restricted to the state ofSão Paulo, the estimates indicate that the Program did not increase real revenue collected by the tertiary sector compared to the other sectors. However, when the increase in tax collection is compared to the estimated raffle prizes the tax collection increases 2% of the average tax collected by the tertiary sector. We then conclude that the impact ofthe Program is very limited. It is

Full Text Available Resumo Em 1968, Augusto Boal dirigiu a I Feira Paulista de Opinião, mobilizando artistas de teatro, música, poesia, cinema, fotografia e artes plásticas. A peça sofreu a censura prévia do Serviço de Censura de Diversões Públicas (SCDP, que lhe aplicou dezenas de cortes que afetariam drasticamente o entendimento pelo público. Muitos dos participantes da Feira - sobretudo o núcleo ligado ao Teatro de Arena de São Paulo ou inspirado por ele - passaram a incorporar diferentes estratégias de ação política em evidência no âmbito nacional e internacional, como desobediência civil, e propor alternativas de resistência político-cultural, como ações judiciais. As conquistas estético-políticas, em maturação desde o final da década de 1950, não foram completamente abolidas, mas foram instrumentalizadas em busca de eficácia política, passado o golpe de 1964. Este artigo analisa pormenores desse evento artístico-cultural, sua relação com a censura teatral e a configuração de espaços alternativos de resistência cultural.

However, there is a paucity of such studies that focus on Neotropical insect groups. Synoeca de Saussure, 1852 is a Neotropical swarm-founding social wasp genus with five described species that is broadly and conspicuously distributed throughout the Neotropics. Here, we infer the phylogenetic relationships, diversification times, and historical biogeography of Synoeca species. We also investigate samples of the disjoint populations of S. septentrionalis that occur in both northwestern parts of South America through Central American and the Brazilian Atlantic rainforests.

Notably, samples of S. septentrionalis and S. surinama collected in the Atlantic Forest were interrelated and may be the result of incomplete lineage sorting and/or mitochondrial introgression among them. Our Bayesian divergence dating analysis revealed recent Plio-Pleistocene diversification in Synoeca. Moreover, our biogeographical analysis suggested an Amazonian origin of Synoeca, with three main dispersal events subsequently occurring during the Plio-Pleistocene.

Structure of ovarioles in adult queens and workers of the common wasp, Vespula germanica (Hymenoptera: Vespidae).

Science.gov (United States)

Jabłońska, A; Biliński, S M

2001-01-01

The ovaries of the common wasp, Vespula germanica are polytrophic-meroistic and consist of 2-3 (workers) or 7 (queens) ovarioles. The ovarioles are differentiated into three regions: a terminal filament, a germarium, and a vitellarium. The germaria of both castes consist of two zones: an anterior zone of germ-cell cluster formation and a posterior one of germ-cell cluster differentiation. The vitellaria comprise 4-6 (workers) or 7-10 (queens) ovarian follicles (egg chambers). Each chamber consists of an oocyte and about 60 isodiametric nurse cells (trophocytes). The egg chambers have been arbitrarily classified into four developmental categories: early and late previtellogenic, vitellogenic, and choriogenic. The process of oogenesis in workers proceeds only up to the onset of the late previtellogenesis. Neither vitellogenic nor choriogenic egg chambers were observed in this caste. During early and late previtellogenesis the envelope of the oocyte nucleus proliferates and becomes highly folded. This process leads to the formation of characteristic organelles, termed accessory nuclei (AN). Although AN arise in the oocytes of both queens and workers, their number in the latter caste is always considerably lower. At the onset of the late previtellogenesis AN start to migrate towards the periphery of the oocyte where they reside till the end of oogenesis. The physiological state of the worker ovaries is discussed in the light of the presented results.

Full Text Available The knowledge on ovigeny in parasitoids is important for basic studies on physiology and applied biological control. The ovigeny pattern and type of ovariole of the parasitoid Palmistichus elaeisis Delvare & LaSalle (Hymenoptera: Eulophidae were studied in newly-emerged females at seven, 14, 24 and 48 h intervals after their emergence from Tenebrio molitor L. pupae (Coleoptera: Tenebrionidae. Females of P. elaeisis presented ovaries composed by four ovarioles of the meroistic polytrophic type. The yolk accumulation and chorionogenesis in P. elaeisis were concluded 24 h after the female emergence. The 48 h-old females show a high quantity of egg ready for oviposition. These findings can help to improve the mass production of P. elaeisis and the augmentative biological control by using this natural enemy.O conhecimento da ovigenia em parasitóides é importante para estudos básicos em fisiologia e para o controle biológico aplicado.

Animal mitochondrial genomes usually exhibit conserved gene arrangement across major lineages, while those in the Hymenoptera are known to possess frequent rearrangements, as are those of several other orders of insects. Here, we sequenced two complete mitochondrial genomes of Trichogramma japonicum and Trichogramma ostriniae (Hymenoptera: Chalcidoidea: Trichogrammatidae). In total, 37 mitochondrial genes were identified in both species. The same gene arrangement pattern was found in the two species, with extensive gene rearrangement compared with the ancestral insect mitochondrial genome. Most tRNA genes and all protein-coding genes were encoded on the minority strand. In total, 15 tRNA genes and seven protein-coding genes were rearranged. The rearrangements of cox1 and nad2 as well as most tRNA genes were novel. Phylogenetic analysis based on nucleotide sequences of protein-coding genes and on gene arrangement patterns produced identical topologies that support the relationship of (Agaonidae + Pteromalidae) + Trichogrammatidae in Chalcidoidea. CREx analysis revealed eight rearrangement operations occurred from presumed ancestral gene order of Chalcidoidea to form the derived gene order of Trichogramma. Our study shows that gene rearrangement information in Chalcidoidea can potentially contribute to the phylogeny of Chalcidoidea when more mitochondrial genome sequences are available.

Full Text Available Las lagunas de estabilización son uno de los sistemas naturales para tratamiento de aguas residuales más adecuados para reducir los impactos ambientales por vertimiento de efluentes en países en vías de desarrollo. La presente investigación tuvo como objetivo diagnosticar la acumulación de lodos y evaluar el desempeño de la planta de tratamiento de aguas residuales de la ciudad Neves Paulista (São Paulo, Brasil. Mediante un estudio batimétrico de las lagunas de estabilización anaerobia y facultativa se determinaron los perfiles y volúmenes de acumulación de lodos; se midieron diversos parámetros de la calidad del agua afluente y efluente, así como el caudal entrante durante 24 horas consecutivas. La batimetría indicó que los lodos acumulados redujeron los volúmenes útiles de las lagunas anaerobia y facultativa en 26,4% y 23,7% respectivamente y que su heterogénea distribución en las unidades de tratamiento afectó su desempeño hidráulico. La eficiencia media de remoción de la DBO fue del 76,6%, inferior a la mínima establecida por la legislación ambiental brasilera. El número más probable de coliformes fecales en el efluente fue de 6,34x10 5 /100mL, que superó en gran medida los valores máximos permitidos para vertimientos en cuerpos receptores. La planta requiere de la implementación de un sistema de pre-tratamiento, de la remoción de los lodos acumulados en las zonas más críticas y la implementación de un sistema de postratamiento que garantice remoción adicional de DBO y coliformes para ajustarse a la normatividad ambiental.

Evidence for Widespread Associations between Neotropical Hymenopteran Insects and Actinobacteria

2017-10-01

Full Text Available The evolutionary success of hymenopteran insects has been associated with complex physiological and behavioral defense mechanisms against pathogens and parasites. Among these strategies are symbiotic associations between Hymenoptera and antibiotic-producing Actinobacteria, which provide protection to insect hosts. Herein, we examine associations between culturable Actinobacteria and 29 species of tropical hymenopteran insects that span five families, including Apidae (bees, Vespidae (wasps, and Formicidae (ants. In total, 197 Actinobacteria isolates were obtained from 22 of the 29 different insect species sampled. Through 16S rRNA gene sequences of 161 isolates, we show that 91% of the symbionts correspond to members of the genus Streptomyces with less common isolates belonging to Pseudonocardia and Amycolatopsis. Electron microscopy revealed the presence of filamentous bacteria with Streptomyces morphology in brood chambers of two different species of the eusocial wasps. Four fungal strains in the family Ophiocordycipitacea (Hypocreales known to be specialized insect parasites were also isolated. Bioassay challenges between the Actinobacteria and their possible targeted pathogenic antagonist (both obtained from the same insect at the genus or species level provide evidence that different Actinobacteria isolates produced antifungal activity, supporting the hypothesis of a defensive association between the insects and these microbe species. Finally, phylogenetic analysis of 16S rRNA and gyrB demonstrate the presence of five Streptomyces lineages associated with a broad range of insect species. Particularly our Clade I is of much interest as it is composed of one 16S rRNA phylotype repeatedly isolated from different insect groups in our sample. This phylotype corresponds to a previously described lineage of host-associated Streptomyces.

The Cimbicidae is a small family of the primitive and relatively less diverse suborder Symphyta (Hymenoptera). Here, nearly complete mitochondrial genome (mitogenome) of hairy sawfly, Corynis lateralis (Hymenoptera: Cimbicidae) was sequenced using next generation sequencing and comparatively analysed with the mitogenome of Trichiosoma anthracinum. The sequenced length of C. lateralis mitogenome was 14,899 bp with an A+T content of 80.60%. All protein coding genes (PCGs) are initiated by ATN codons and all are terminated with TAR or T- stop codon. All tRNA genes preferred usual anticodons. Compared with the inferred insect ancestral mitogenome, two tRNA rearrangements were observed in the IQM and ARNS1EF gene clusters, representing a new event not previously reported in Symphyta. An illicit priming of replication and/or intra/inter-mitochondrial recombination and TDRL seem to be responsible mechanisms for the rearrangement events in these gene clusters. Phylogenetic analyses confirmed the position of Corynis within Cimbicidae and recovered a relationship of Tenthredinoidea + (Cephoidea + Orussoidea) in Symphyta.

Abstract In newly invaded communities, interspecific competition is thought to play an important role in determining the success of the invader and its impact on the native community. In southern Australia, the native Polistes humilis was the predominant social wasp prior to the arrival of the exotic Vespula germanica (Hymenoptera: Vespidae). Both species forage for similar resources (water, pulp, carbohydrate and protein prey), and concerns have arisen about potential competition between them. The aim of this study was to identify the protein foods that these wasps feed on. As many prey items are masticated by these wasps to the degree that they cannot be identified using conventional means, morphological identification was complemented by sequencing fragments of the mitochondrial 16S rRNA gene. GenBank searches using blast and phylogenetic analyses were used to identify prey items to at least order level. The results were used to construct complete prey inventories for the two species. These indicate that while P. humilis is restricted to feeding on lepidopteran larvae, V. germanica collects a variety of prey of invertebrate and vertebrate origin. Calculated values of prey overlap between the two species are used to discuss the implications of V. germanica impacting on P. humilis. Results obtained are compared to those gained by solely 'conventional' methods, and the advantages of using DNA-based taxonomy in ecological studies are emphasized.

The study objectives were: (1) to field test potential repellency of common essential oils against several pestiferous social wasps (Hymenoptera: Vespidae), using attractant-baited traps; (2) to identify vespid antennally active compounds from the repellent essential oils; (3) to determine potential repellency of these electroantennographic detection (EAD) active compounds in the field. Of the 21 essential oils tested, 17 showed significant repellency on yellowjackets [mainly Vespula pensylvanica (Saussure)] and paper wasps [mainly Polistes dominulus (Christ)]: clove, pennyroyal, lemongrass, ylang ylang, spearmint, wintergreen, sage, rosemary, lavender, geranium, patchouli, citronella, Roman chamomile, thyme, fennel seed, anise and peppermint. Two essential oil mixtures - 3EO-mix (clove, geranium and lemongrass) and 4EO-mix (clove, geranium, lemongrass and rosemary) - totally blocked the attraction of vespid workers. Twenty-nine vespid antennally active compounds were identified from solid-phase microextraction (SPME) samples of 11 strongly repellent essential oils by GC-EAD/MS techniques. Among the synthetic EAD-active compounds field tested, eugenol, P/I-menthone, pulegone, α/β-thujone, l-carvone, E/Z-citral, citronellal, methyl benzoate, benzyl acetate, methyl salicylate and 3-octanol showed a significant repellency on vespid workers. These compounds are likely responsible for the repellency of their corresponding essential oils. These repellent essential oils and their active compositions have great potential for efficient, environmentally sound semiochemical-based IPM of pestiferous vespid wasps. © 2012 Society of Chemical Industry.

Full Text Available Resumo: Na atividade canavieira paulista constatou-se prejuízo econômico entre as safras 2007/08 e 2011/12, fato que leva ao objetivo do presente estudo: responder por que estes produtores mantêm-se no fornecimento de cana-de-açúcar. Além da análise tradicional de viabilidade, o estudo incorporou à análise o uso da Teoria das Opções Reais, proposta que inclui no modelo de decisão a flexibilidade gerencial do investidor. Foram analisados dois projetos típicos de investimento em cana-de-açúcar nas regiões de Piracicaba e Sertãozinho. Considerando-se o método do fluxo de caixa descontado, obteve-se estimativas que apontam para a atratividade econômica do plantio de cana em ambas as regiões, haja vista a resposta positiva dos Valores Presentes Líquidos calculados. Tais evidências foram corroboradas quando da utilização da Teoria das Opções Reais, proposta que incorpora no modelo de decisão a flexibilidade gerencial do investidor. Ressaltam-se como principais parâmetros de impacto na viabilidade financeira de empreendimentos canavieiros o preço e a qualidade da cana-de-açúcar e a produtividade agrícola. Ações que visem ganhos de produtividade agrícola são apontadas como motivadoras de ganhos financeiros, enquanto que, em termos de políticas públicas, cita-se a possibilidade de ajustes no sistema de precificação da gasolina C e na tributação dos derivados da cana-de-açúcar.

Full Text Available Este trabalho focaliza a homogeneidade da paisagem urbana das cidades de porte médio do interior do estado de São Paulo do ponto de vista de seus determinantes paisagísticos. A origem socioeconômica das cidades determina, em um primeiro momento, sua configuração, a qual, esgotado o estímulo inicial, passa a incorporar as imagens formais das grandes cidades. Estas imagens estão claramente representadas de um modo específico na paisagem urbana dessas cidades, evidenciando os reflexos formais e funcionais das paisagens dos grandes centros, e na geração de valores estéticos e de uso do espaço relacionados aos aspectos formais e visuais que se fazem presentes em suas paisagens. A legislação que define os padrões de ocupação urbana, os quais por sua vez definem a configuração física da paisagem, trabalha basicamente o espaço físico-territorial, alienando-se dos demais componentes da problemática urbana, e, desta forma, as cidades se homogeneízam. Ou seja, gera um discurso urbanístico pobre e o que se faz é generalista. A paisagem da cidade média paulista é então homogênea como conseqüência desta forma de ocupação homogênea. Como contraposição à paisagem homogênea, algumas condições ambientais e paisagísticas locais, como a presença de um rio ou de uma topografia acidentada, servem de início como determinantes para projetos urbanísticos/paisagísticos diferenciados e característicos para cada cidade, mas no momento seguinte os elementos da" moda" entram na composição da paisagem, descaracterizando o padrão diferenciado inicial.

Apiculture in Brazil is quite profitable and has great potential for expansion because of the favorable climate and abundancy of plant diversity. However, the occurrence of pests, diseases, and parasites hinders the growth and profitability of beekeeping. In the interior of the state of São Paulo, apiaries are attacked by ants, especially the species Camponotus atriceps (Smith) (Hymenoptera: Formicidae), which use the substances produced by Apis mellifera scutellata (Lepeletier) (Hymenoptera: Apidae), like honey, wax, pollen, and offspring as a source of nourishment for the adult and immature ants, and kill or expel the adult bees during the invasion. This study aimed to understand the invasion of C. atriceps in hives of A. m. scutellata. The individuals were classified into castes and subcastes according to morphometric analyses, and their cuticular chemical compounds were identified using Photoacoustic Fourier transform infrared spectroscopy (FTIR-PAS). The morphometric analyses were able to classify the individuals into reproductive castes (queen and gynes), workers (minor and small ants), and the soldier subcaste (medium and major ants). Identification of cuticular hydrocarbons of these individuals revealed that the eight beehives were invaded by only three colonies of C. atriceps; one of the colonies invaded only one beehive, and the other two colonies underwent a process called sociotomy and were responsible for the invasion of the other seven beehives. The lack of preventive measures and the nocturnal behavior of the ants favored the invasion and attack on the bees.

Development of antennal sensilla of Tetragonisca angustula Latreille, 1811 (Hymenoptera: Meliponini during pupation

Directory of Open Access Journals (Sweden)

V. T. Dohanik

Full Text Available Abstract The antennal sensilla are sensory organs formed by a group of neurons and accessory cells, which allow perception of environmental cues, which play a role as mechanoreceptors and chemoreceptors. This study describes the post-embryonic development of the antennal sensilla of the stingless Tetragonisca angustula (Hymenoptera: Meliponini workers. The development of the antennal sensilla begins in the transition stage of the pre-pupae to white-eyed pupae. The sensilla are completely developed at the black-eyed pupae stage, but they are covered by the old cuticle. The sensilla are exposed to the environment only in newly emerged workers of T. angustula, but it is possible that environmental stimuli can be recognized due to the pores in the old cuticle.

Full Text Available A colony of the encyrtid wasp Psyllaephagus euphyllurae (Masi (Hymenoptera, Encyrtidae has been established in the quarantine laboratory at the University of California, Riverside, California, USA as part of a classical biological control program against its invasive host, the olive psylla, Euphyllura olivina (Costa (Hemiptera, Psylloidea, Liviidae, an important pest of olives in some parts of the world. The colony originators were reared from the same host found on abandoned, commercial olives in Catalonia, Spain; additional collections were made in Murcia. The parasitoid reproduces primarily by thelytoky; however, a few occasional males have been found in the field in Spain, but not in colonies reared under quarantine or laboratory conditions. Here, the female of P. euphyllurae is redescribed and its male is described and illustrated for the first time; the only previous mention of male P. euphyllurae was from Tunisia, reared from the same psyllid host but without any details on its morphology. A lectotype is designated for Encyrtus euphyllurae Masi. Information is given on the results of genetic matching between the two sexes of the parasitoid and also on the presence of the bacterial Wolbachia symbiont that apparently is affecting reproduction of this species, including its sex ratio in the field. Two species of hyperparasitoids have also emerged from the parasitized olive psylla nymphs from Catalonia: numerous specimens of Apocharips trapezoidea (Hartig (Hymenoptera, Figitidae and one specimen of a Pachyneuron sp.

Gregarious nesting behavior occurs in a broad diversity of solitary bees and wasps. Despite the prevalence of aggregative nesting, the underlying drivers and fitness consequences of this behavior remain unclear. I investigated the effect of two key characteristics of nesting aggregations (cavity availability and progeny density) on reproduction and brood parasitism rates in the blue orchard bee (Osmia lignaria Say) (Hymenoptera: Megachilidae), a solitary species that nests gregariously and appears to be attracted to nesting conspecifics. To do so, I experimentally manipulated nest cavity availability in a region of northern Utah with naturally occurring populations of O. lignaria. Nest cavity availability had a negative effect on cuckoo bee (Stelis montana Cresson) (Hymenoptera: Megachilidae) parasitism rates, with lower parasitism rates occurring in nest blocks with more available cavities. For both S. montana and the cleptoparasitic blister beetle Tricrania stansburyi Haldeman (Coleoptera: Meloidae), brood parasitism rate was negatively correlated with log-transformed O. lignaria progeny density. Finally, cavity availability had a positive effect on male O. lignaria body weight, with the heaviest male progeny produced in nest blocks with the most cavities. These results suggest that cavity availability and progeny density can have substantial effects on brood parasitism risk and reproduction in this solitary bee species. © The Author(s) 2017.

Description of five species of Xanthopimpla Saussure, 1829 (Hymenoptera: Ichneumonidae: Pimplinae) from Malaysia was done using specimens deposited in Centre for Insects Systematics, Universiti Kebangsaan Malaysia (CIS, UKM). Type and non-type specimens were loaned from several repositories namely Zoological Museum of Amsterdam Netherlands (ZMAN), Swedish Museum of Natural History (NRM), British Natural History Museum London (BMNH) and Department of Agricultural Malaysia (DOA) for identification and comparison. The specimens were identified to the species level which gives rise to five species namely Xanthopimpla conica Cushman, 1925, Xanthopimpla despinosa leipephelis Townes & Chiu, 1970, Xanthopimpla flavolineata Cameron, 1907, Xanthopimpla punctata (Fabricius, 1781) and Xanthopimpla tricapus impressa Townes & Chiu, 1970. A dichotomous key and descriptions for five Xanthopimpla spesies were provided. Photos and illustrations of carina on propodeum were also included in this paper.

Full Text Available A new genus and species of Mesoserphidae (Hymenoptera, Juraserphus modicus gen. et sp. nov., is described based on a well-preserved fossil specimen from the Middle Jurassic Jiulongshan Formation of northeastern China. It is characterized by the following forewing features: the forking of Rs+M located approximately one-third of the distance between 1m-cu and 2r-rs, both 1cu-a and 2cu-a antefurcal; 1-M more than twice as long as 1m-cu and hind wing with cells r and rm closed. In addition, it has a short ovipositor, only extending slightly beyond the metasomal apex. Its new morphological characters broaden the diversity of Mesoserphidae in the Mesozoic and provide new insights into the evolution and relationships of Mesoserphidae.

Phylogeographic analysis reveals high genetic structure with uniform phenotypes in the paper wasp Protonectarina sylveirae (Hymenoptera: Vespidae)

Science.gov (United States)

2018-01-01

Swarm-founding wasps are endemic and common representatives of neotropical fauna and compose an interesting social tribe of vespids, presenting both complex social characteristics and uncommon traits for a eusocial group, such as the absence of castes with distinct morphology. The paper wasp Protonectarina sylveirae (Saussure) presents a broad distribution from Brazil, Argentina and Paraguay, occurring widespread in the Atlantic rainforest and arboreal Caatinga, being absent in the Amazon region. Given the peculiar distribution among swarm-founding wasps, an integrative approach to reconstruct the evolutionary history of P. sylveirae in a spatial-temporal framework was performed to investigate: the presence of genetic structure and its relationship with the geography, the evolution of distinct morphologic lineages and the possible historical event(s) in Neotropical region, which could explain the observed phylogeographic pattern. Individuals of P. sylveirae were obtained from populations of 16 areas throughout its distribution for DNA extraction and amplification of mitochondrial genes 12S, 16S and COI. Analysis of genetic diversity, construction of haplotype net, analysis of population structure and dating analysis of divergence time were performed. A morphometric analysis was also performed using 8 measures of the body of the adult (workers) to test if there are morphological distinction among populations. Thirty-five haplotypes were identified, most of them exclusively of a group and a high population structure was found. The possibility of genetic divergence because of isolation by distance was rejected. Morphological analysis pointed to a great uniformity in phenotypes, with only a small degree of differentiation between populations of south and the remaining. Divergence time analysis showed a Middle/Late Miocene origin, a period where an extensive marine ingression occurred in South America. Divergence of haplogroups began from the Plio/Pleistocene boundary and the last glacial maximum most likely modeled the current distribution of species, even though it was not the cause of genetic breaks.

The genus Antodynerus de Saussure, 1855 is reviewed from the Indian subcontinent. Three species with one additional subspecies are present, namely Antodynerus flavescens flavescens (Fabricius, 1775), A. f. karachiensis Giordani Soika, 1970, A. limbatus (de Saussure, 1852), and A. punctatipennis (de Saussure, 1853). The parasitic association of strepsipteran insects and the symbiotic association of mites are reported for the first time in the genus Antodynerus. The distribution of A. f. flavescens (Fabricius) and A. limbatus (de Saussure) in the Indian states is augmented. The latter species is newly recorded from China (Tibet). A key to species of the Indian subcontinent is provided.

Cely and Sarmiento (2011) took issue with the cladistic analysis of relationships among species of the genus Synoeca by Andena et al. (2009a), and presented a reanalysis. They claimed that intraspecific variation in the genus is meaningful, and proper consideration yields a conclusion different from that of Andena et al. Both their critique and reanalysis are vitiated by numerous errors, as is shown in the present paper.

Full Text Available Females of Quartinia major Kohl were observed to visit flowers of Pulicaria mauritanica Batt., Cladanthus arabicus (L. Cass. and Asteriscus graveolens (Forssk. Less., (all Asteroideae Asteraceae at two localities in southern Morocco. Pollen in the provisions of two brood cells was more than 99% Aster-type (Asteroideae, indicating broad oligolecty. During pollen uptake from P. mauritanica, the females of Q. major employed a hitherto undescribed harvesting technique: They used their mouthparts to squeeze pollen from the corolla tubes of early male phase disc florets. Pollen was ingested immediately after it had been extracted. The nest was a multicellular subterranean burrow excavated in friable soil and surmounted by a turret. The nest walls were stabilized with self-generated silk.

T cells from peripheral blood of hymenoptera sensitive patients were studied before and after venom desensitization. Before treatment, T cells showed a variable but higher proliferative response to allergen than T cells of treated patients or controls. While before desensitization, T cell products, specifically released after in vitro allergen stimulation, were able to amplify the IgE-dependent platelet activity, we showed that after treatment of the same patients, T cell products strongly reduced platelet activation. Considering the modifications in platelet activation previously observed in patients treated by specific immunotherapy, the present results suggest that, through a modification of T cell reactivity to allergen, T cell functions are modulated by desensitization, and emphasize the involvement of T cell products in the desensitization mechanisms.

Full Text Available The sting microsculpture of the digger wasp Bembix rostrata (Fabricius, 1781 (Hymenoptera, Crabronidae is studied with the scanning electron microscope (SEM for the first time. As in many other hymenopterans, the second valvifer of B. rostrata possesses two fields of styloconic sensilla (hair plates of proprioceptive function. The presence of two paired fields of campaniform sensilla on the second valvula and second valvifer is first shown in an apoid wasp. The first and the second valvulae bear scattered sensilla-like structures on the external surface, more numerous apically. The first valvula has two subapical barbs externally and a pair of valvilli on its inner surface, whereas the outer surface of the second valvula is smooth. The third valvula is sclerotized externally, consisting of proximal and distal parts, and bearing four sensilla morphotypes of mechanoreceptive and probably chemoreceptive functions. The inner surface of the valvulae and the membranous cuticle that is touching the sting have microstructures of different shapes directed distally. Functional aspects of characters studied are discussed.

A cuckoo in wolves' clothing? Chemical mimicry in a specialized cuckoo wasp of the European beewolf (Hymenoptera, Chrysididae and Crabronidae

Full Text Available Abstract Background Host-parasite interactions are among the most important biotic relationships. Host species should evolve mechanisms to detect their enemies and employ appropriate counterstrategies. Parasites, in turn, should evolve mechanisms to evade detection and thus maximize their success. Females of the European beewolf (Philanthus triangulum, Hymenoptera, Crabronidae hunt exclusively honeybee workers as food for their progeny. The brood cells containing the paralyzed bees are severely threatened by a highly specialized cuckoo wasp (Hedychrum rutilans, Hymenoptera, Chrysididae. Female cuckoo wasps enter beewolf nests to oviposit on paralyzed bees that are temporarily couched in the nest burrow. The cuckoo wasp larva kills the beewolf larva and feeds on it and the bees. Here, we investigated whether H. rutilans evades detection by its host. Since chemical senses are most important in the dark nest, we hypothesized that the cuckoo wasp might employ chemical camouflage. Results Field observations suggest that cuckoo wasps are attacked by beewolves in front of their nest, most probably after being recognized visually. In contrast, beewolves seem not to detect signs of the presence of these parasitoids neither when these had visited the nest nor when directly encountered in the dark nest burrow. In a recognition bioassay in observation cages, beewolf females responded significantly less frequently to filter paper discs treated with a cuticular extract from H. rutilans females, than to filter paper discs treated with an extract from another cuckoo wasp species (Chrysis viridula. The behavior to paper discs treated with a cuticular extract from H. rutilans females did not differ significantly from the behavior towards filter paper discs treated with the solvent only. We hypothesized that cuckoo wasps either mimic the chemistry of their beewolf host or their host's prey. We tested this hypothesis using GC-MS analyses of the cuticles of male and

Full Text Available Morphological, chemical and developmental aspects of the Dufour gland in some eusocial bees (Hymenoptera, Apidae: a review. The present revision focused on the more recent data about the Dufour gland in some eusocial bees, taking in account general aspects of its morphology, secretion chemical nature, bio-synthetic pathway and development. Many functions have been attributed to this gland in eusocial bees, but none are convincing. With the new data about this gland, not only the secretion chemical pathway of the Dufour gland may be reasonable understood, as its function in some eusocial bees, especially Apis mellifera Linné, 1758, which has been extensively studied in the last years.Aspectos morfológicos, químicos e do desenvolvimento da glândula de Dufour em algumas abelhas eussociais (Hymenoptera, Apidae: revisão.

Up to 75% of patients with severe anaphylactic reactions after Hymenoptera sting are at risk of further severe reactions if re-stung. Venom immunotherapy (VIT) is highly effective in protecting individuals with ascertained Hymenoptera venom allergy (HVA) and previous severe reactions. After a 3- to 5-year VIT course, most patients remain protected after VIT discontinuation. Otherwise, a lifelong treatment should be considered in high-risk patients (eg, in mastocytosis). Several case reports evidenced that patients with mastocytosis and HVA, although protected during VIT, can re-experience severe and sometimes fatal reactions after VIT discontinuation. To evaluate whether patients who lost protection after VIT discontinuation may suffer from clonal mast cell disorders. The survey describes the characteristics of patients who received a full course of VIT for previous severe reactions and who experienced another severe reaction at re-sting after VIT discontinuation. Those with a Red Española de Mastocitosis score of 2 or more or a serum basal tryptase level of more than 25 ng/mL underwent a hematological workup (bone marrow biopsy, KIT mutation, expression of aberrant CD25) and/or skin biopsy. Nineteen patients (mean age, 56.3 years; 89.5% males) were evaluated. All of them had received at least 4 years of VIT and were protected. After VIT discontinuation they were re-stung and developed, in all but 1 case, severe anaphylactic reactions (12 with loss of consciousness, in the absence of urticaria/angioedema). Eighteen patients (94.7%) had a clonal mast cell disorder, 8 of them with normal tryptase. Looking at this selected population, we suggest that mastocytosis should be considered in patients developing severe reactions at re-sting after VIT discontinuation and, as a speculation, patients with mastocytosis and HVA should be VIT-treated lifelong.

Full Text Available Interest for insect farming is currently growing globally. Conditions in West Africa appear suitable for developing such farming systems that can benefit communities by improving livelihoods, food and feed security or sanitation. In Ghana and Mali, the Black Soldier Fly (Hermetia illucens Linnaeus, 1758 is being produced for waste recycling and animal feed. In a two stages process (egg and larvae production, egg production was hampered by a pupal parasitoid, Dirhinus giffardii Silvestri, 1913 (Hymenoptera: Chalcididae, which reduced future broodstock by almost 72%. This is the first time D. giffardii is reported as a parasitoid of H. illucens pupae and one of the first reports of parasitism in this commercially important fly species. The introduction of precautionary measures is highly recommended for the success of H. illucens production systems in West Africa.

The studied site is located at an altitude of 1450 m, on the south face of the Sierra de Guadarrama (Central Spain, about 60 km NW from Madrid. Between 1988 and 1991 an insect biodiversity inventory was carried out using three sampling methods: Malaise traps, yellow pan traps and sweep nets. Out of the more than 1,000,000 insects trapped, increasing the collections of the MNCN, about 600,000 were sorted to order. We found 83,688 individuals of Hymenoptera (representing 13,8% and the second more abundant group in the samples, after Diptera (450,000 individuals and 77,5% of total. Forty nine families, 518 genera and 1310 species de Hymenoptera has been identified until now. The overall richness of Hymenoptera from El Ventorrillo is estimated in 2700 species and about 13,000 the number of insect species from the study site. An appendix is provided with the list of identified species and its overall abundance in the samples. As results of the inventory, ten new species for science have been described, and several more new species are not yet described; additionally, at least 33 genera and more than 170 species were recorded for the first time for Iberia. The abundance of Hymenoptera, as measured by Malaise trap catches, was very high, comparatively to other published data, reaching a peak of 916 individuals per trap day at the most productive trap and sampling period. The more abundant families were, in decreasing order, Braconidae, Ichneumonidae, Mymaridae, Scelionidae, Apidae and Pteromalidae, represented by numbers of individuals between 12,000, for Braconidae, to near 6000 for Pteromalidae. Among the identified families, the more species rich at the study area were in decreasing order: Pteromalidae (290, Ichneumonidae (217, Sphecidae (107 and Eulophidae (101 species.

Full Text Available O artigo apresenta resultados finais de pesquisa interinstitucional que teve por objetivo analisar a natureza e as consequências de parcerias firmadas entre setores privados e governos municipais paulistas para atendimento da educação infantil e do ensino fundamental. O período correspondeu aos anos de 1996 a 2006, tendo em vista a percepção de que o aumento das responsabilidades dos municípios pela oferta educacional, decorrente da municipalização do ensino fundamental, poderia estimular processos de privatização da educação municipal, por meio do aumento de "parcerias" entre a gestão municipal e o setor privado lucrativo e não lucrativo. O estudo apresenta tendências relacionadas a três modalidades de parcerias: subvenção pública para oferta de vagas em instituições privadas de educação infantil, aquisição de "sistemas" privados de ensino e contratação de assessoria privada para a gestão da educação municipal. As tendências percebidas na análise indicam que as atuais relações entre as esferas públicas e privadas no campo da educação, decorrentes da descentralização havida no setor, representam um movimento em direção a sua privatização.

Esta pesquisa teve por objetivos caracterizar o perfil da demanda encaminhada por queixa escolar aos serviços públicos de saúde de um município do interior paulista no período 2010-2011, bem como identificar e analisar a conduta adotada pelos profissionais da Psicologia no atendimento destinado a ela. Unidades Básicas de Saúde e o Centro Integrado de Atenção Psicossocial – CIAPS – foram os locais designados para a coleta dos dados por serem responsáveis pelo atendimento à população infantil. O estudo contemplou análise documental dos registros sobre a demanda encaminhada e entrevista semiestruturada com os psicólogos que trabalham nos respectivos espaços. Os resultados confirmaram o que aponta a literatura na área da Psicologia Escolar com destaque para o encaminhamento de crianças do sexo masculino com idades entre sete e dez anos que cursam o início do primeiro ciclo do ensino fundamental. Com relação às concepções e práticas profissionais, constatou-se o predomínio do modelo clínico de atenção e certa dificuldade na efetivação de novas formas de atuar. Apesar dos avanços teórico-metodológicos propostos em novas concepções sobre as queixas escolares, estes ainda não se fazem suficientemente presentes na prática desses profissionais.

A new species of Anagyrus Howard (Hymenoptera: Encyrtidae), A. lapachosus sp. n., is described from Salta Province of Argentina as a parasitoid of Hypogeococcus sp. (Hemiptera: Pseudococcidae) on Harrisia pomanensis cactus (Cactaceae). It is a candidate "new association" biological control agent for quarantine evaluation and possible following introduction to Puerto Rico (USA) against another Hypogeococcus sp., commonly called the Harrisia cactus mealybug and often misidentified as H. pungens Granara de Willink (according to our unpublished data the latter attacks only Amaranthaceae), which devastates or threatens the native cacti there and also in some other Caribbean islands (Triapitsyn, Aguirre et al. 2014; Carrera-Martínez et al. 2015).

Function and evolution of microRNAs in eusocial Hymenoptera

Full Text Available The emergence of eusociality (true sociality in several insect lineages represents one of the most successful evolutionary adaptations in the animal kingdom in terms of species richness and global biomass. In contrast to solitary insects, eusocial insects evolved a set of unique behavioral and physiological traits such as reproductive division of labor and cooperative brood care, which likely played a major role in their ecological success. The molecular mechanisms that support the social regulation of behavior in eusocial insects, and their evolution, are mostly unknown. The recent whole-genome sequencing of several eusocial insect species set the stage for deciphering the molecular and genetic bases of eusociality, and the possible evolutionary modifications that led to it. Studies of mRNA expression patterns in the brains of diverse eusocial insect species have indicated that specific social behavioral states of individual workers and queens are often associated with particular tissue-specific transcriptional profiles. Here we discuss recent findings that highlight the role of non-coding microRNAs (miRNAs in modulating traits associated with reproductive and behavioral divisions of labor in eusocial insects. We provide bioinformatic and phylogenetic data, which suggest that some Hymenoptera-specific miRNA may have contributed to the evolution of traits important for the evolution of eusociality in this group.

Function of the Dufour’s gland in solitary and social Hymenoptera

Directory of Open Access Journals (Sweden)

2013-10-01

Full Text Available The poison gland and Dufour’s gland are the two glands associated with the sting apparatus in female Apocrita (Hymenoptera. While the poison gland usually functions as an integral part of the venom delivery system, the Dufour’s gland has been found to differ in its function in various hymenopteran groups. Like all exocrine glands, the function of the Dufour’s gland is to secrete chemicals, but the nature and function of the secretions varies in different taxa. Functions of the Dufour’s gland secretions range from serving as a component of material used in nest building, larval food, and pheromones involved in communicative functions that are important for both solitary and social species. This review summarizes the different functions reported for the Dufour’s gland in hymenopterans, illustrating how the Dufour’s gland secretions can be adapted to give rise to various functions in response to different challenges posed by the ways of life followed by different taxa. Aspects of development, structure, chemistry and the evolution of different functions are also touched upon briefly.

This paper is aimed to summarize the information available on the parasitoid complex of the European Grapevine Moth (EGVM), Lobesia botrana (Denis & Schiffermüller, 1775) (Lepidoptera Tortricidae) in Italy. The list is the result of the consultation of a vast bibliography published in Italy for almost two hundred years, from 1828 to date. This allowed the clarification and correction of misunderstandings and mistakes on the taxonomic position of each species listed. In Italy the complex of parasitoids detected on EGVM includes approximately 90 species belonging to ten families of Hymenoptera (Braconidae, Ichneumonidae, Chalcididae, Eulophidae, Eupelmidae, Eurytomidae, Pteromalidae, Torymidae, Trichogrammatidae, and Bethylidae) and one family of Diptera (Tachinidae). This paper deals with EGVM parasitoids of the families Tachinidae (Diptera) and Braconidae (Hymenoptera). Only two species of Tachinidae are associated to EGVM larvae in Italy, Actia pilipennis (Fallen) and Phytomyptera nigrina (Meigen), whereas the record of Eurysthaea scutellaris (Robineau-Desvoidy) is doubtful. Moreover, 21 species of Braconidae are reported to live on EGVM, but, unfortunately, eight of them were identified only at generic level. Bracon mellitor Say has been incorrectly listed among the parasitoids of Lobesia botrana . Records concerning Ascogaster rufidens Wesmael, Meteorus sp., Microgaster rufipes Nees, and Microplitis tuberculifer (Wesmael) are uncertain.

Blueberry scorch virus, a commercially important Carlavirus in highbush blueberry, Vaccinium corymbosum L., is vectored by aphids (Hemiptera: Aphididae). We surveyed the aphids, primary parasitoids (Hymenoptera: Aphelinidae, Braconidae), and associated secondary parasitoids (Hymenoptera: Charipidae, Megaspilidae, Pteromalidae) on highbush blueberry and other Vaccinium in the Pacific Northwest from 1995 to 2006, with samples concentrated in 2005 and 2006, to lay the groundwork for augmentative biological control. Ericaphis fimbriata (Richards) was the principal aphid. The dominant parasitoid species were Praon unicum Smith, Aphidius n. sp., A. sp., and Aphidius ervi Haliday. Their frequency in relation to the other primary parasitoids varied significantly with geographical area; P. unicum dominated the frequency distribution in southwestern British Columbia, A. n. sp., west of the Cascades, and A. sp. and A. ervi east of the Cascades. Among the secondary parasitoids, pteromalids dominated, and their frequency in relation to the other secondary parasitoids was lowest in southwestern British Columbia. The parasitization rate for P. unicum and A. n. sp. in southwestern British Columbia increased from May or June to a maximum of 0.080 +/- 0.024 and 0.090 +/- 0.084 (SD), respectively, in late July or early August. P. unicum emerged in the spring 4 wk before A. n. sp. The parasitization rate for P. unicum was lower in conventional than organic fields. Whereas aphid density increased monotonically, P. unicum had two spring peaks. A simulation model showed that these peaks could reflect discrete generations. Releases of insectary-reared P. unicum at 150 or 450 DD above 5.6 degrees C, summing from 1 January, may effectively augment the natural spring populations by creating overlapping generations.

Observations on Forced Colony Emigration in Parachartergus fraternus (Hymenoptera: Vespidae: Epiponini: New Nest Site Marked with Sprayed Venom

Directory of Open Access Journals (Sweden)

Sidnei Mateus

2011-01-01

Full Text Available Five cases of colony emigration induced by removal of nest envelope and combs and a single one by manipulation are described. The disturbance was followed by defensive patterns, buzz running, and adult dispersion. An odor trail created by abdomen dragging, probably depositing venom or Dufour's gland secretions, connected the original nest to the newly selected nesting place and guided the emigration. The substrate of the selected nesting place is intensely sprayed with venom prior to emigration, and this chemical cue marked the emigration end point. The colony moves to the new site in a diffuse cloud with no temporary clusters formed along the odor trail. At the original nest, scouts performed rapid gaster dragging and intense mouth contacts stimulating inactive individuals to depart. Males were unable to follow the swarm. Individual scouts switched between different behavioral tasks before and after colony emigration. Pulp collected from the old nest was reused at the new nest site.

Horismenus abnormicaulis sp. nov., H. patensis sp. nov. and H. zuleidae sp. nov. (Hymenoptera: Eulophidae), all authored by Pikart, Costa & Hansson, are described from material obtained from seed pods of Pithecellobium dulce (Roxb.) Benth. (Fabaceae) collected in Northeastern Brazil. The seed pods were infested with larvae of Coleoptera (Chrysomelidae (Bruchinae) and Curculionidae). The associations of the Horismenus species and the beetle larvae have not been established. Morphological similarities between these new species and previously described species with host known suggest that H. patensis and H. zuleidae are primary parasitoids of Bruchinae, whereas H. abnormicaulis may act as a hyperparasitoid on other Horismenus species. The three species are compared with similar species of Horismenus.

Full Text Available Nests of Centris tarsata Smith, 1874 were obtained from trap-nests in areas of dry semi-deciduous forest (Baixa Grande and caatinga (Ipirá, in the State of Bahia. Nesting occurred in bamboo canes and in tubes of black cardboard with 5.8 cm (= small tube and 10.5 cm (= large tube in length and 0.6 and 0.8 cm in diameter, respectively. In both areas C. tarsata nested during the wet season producing four generations in Baixa Grande and three generations in Ipirá. The immatures of one generation underwent diapause at both sites. The bees constructed their nests with a mixture of sand and oil. In general, the cells were elongated and arranged in linear series with its opening pointing towards the nest entrance. Completed nests had two to three cells in small tubes, one to seven cells in large tubes, and two to 13 cells in bamboo canes. The nest plug resembled an uncompleted cell and was externally covered with oil. The cells were provisioned with pollen, oil, and nectar. Nests were parasitized by Mesocheira bicolor (Fabricius, 1804 (Hymenoptera: Apidae and other not identify bee species.Ninhos de Centris tarsata Smith, 1874 foram obtidos através da utilização de ninhos-armadilha, em áreas de floresta estacional semi-decídua (Baixa Grande e de caatinga (Ipirá, no Estado da Bahia.

Cruz, L C; Araújo, V A; Dolder, H; Araújo, A P A; Serrão, J E; Neves, C A

2011-01-01

In Hymenoptera, midgut changes begin in the last instar. At this stage, the larval epithelial digestive cells degenerate, leaving only the basal membrane and the regenerative cells which will develop into a new epithelium during the pupal stage and in the adult. Epithelium renewal is followed by changes in volume and shape of the midgut. Morphometric analysis of digestive cells and total midgut volume of Melipona quadrifasciata anthidioides (Lepeletier) were conducted to verify whether cell volume increase are sufficient to account for the total midgut volume increase that occurs during metamorphosis. An increase in midgut volume was verified in spite of the scarcity of cell proliferation found during metamorphosis. At the end of metamorphosis, the increase in cell volume was not sufficient to explain the increase in volume of the midgut, indicating that an increase in the number of digestive cells is apparently necessary. Nevertheless, the mechanism by which regenerative cells reconstitute the epithelium during metamorphosis remains unknown.

The effect of nine insecticides used in tomato production was evaluated on adults of two Trichogramma pretiosum Riley (Hymenoptera: Trichogrammatidae) populations from Rive and Afonso Cláudio, Espírito Santo State, Brazil. The experiment was developed in an acclimatized chamber at 25 +/- 1 degrees C, 70 +/- 10% relative humidity and 14 h photophase. Eggs of Anagasta kuehniella (Lepidoptera: Pyralidae), previously immersed in insecticides solutions were offered to females of both T. pretiosum populations. Bacillus thuringiensis, lufenuron and triflumuron had lowest negative effects on parasitism and viability of individuals of these populations; however, abamectin and pyrethroids (betacyflurin 50 and 125 g/l and esfenvalerate) insecticides reduced parasitism rates. T. pretiosum emerged from A. kuehniella eggs treated with esfenvalerate but were not able to parasitize non treated eggs of this host. B. thuringiensis, lufenuron and triflumuron may be used in integrated pest management programs to control tomato pests, because they have moderated negative effect on parasitoid wasps.

Full Text Available Os Estudos de Linha de Base do Projeto de Expansão e Consolidação do Saúde da Família construíram indicadores e modelos de atenção básica para os 62 municípios paulistas com mais de 100 mil habitantes, e apontaram uma diversidade de comportamento destes indicadores e modelos em relação às diferentes dinâmicas urbanas do estado. Nesse sentido, houve a necessidade de realizar uma reflexão sobre saúde e uso urbano do território. O principal objetivo desta reflexão foi compreender melhor sobre como a dinâmica urbana tem influência no perfil, na organização e no funcionamento do sistema de saúde. A partir daí, foi possível extrair algumas hipóteses e discussões sobre como a urbanização paulista impõe desafios à expansão e consolidação da atenção básica e do Programa Saúde da Família nos municípios estudados.The Baseline Studies on the Project for Expansion and Consolidation of the Family Health Strategy created primary health care indicators and models for the 62 municipalities with more than 100,000 inhabitants in São Paulo State, Brazil, and identified varying patterns for these indicators and models in relation to different urban dynamics in the State. The studies showed the need to reflect on health in relation to urban land use. The main objective was to gain a better understanding of how urban dynamics influence the health system's profile, organization, and operation, based on which it was possible to extract some hypotheses and discussions regarding how urbanization in São Paulo State creates challenges for the expansion and consolidation of primary health care and the Family Health Program in these municipalities.

Full Text Available Foraging strategies of the ant Ectatomma vizottoi (Hymenoptera, Formicidae. Foraging activity may be limited by temperature, humidity, radiation, wind, and other abiotic factors, all of which can affect energy costs during foraging. Ectatomma vizottoi's biology has only recently been studied, and no detailed information is available on its foraging patterns or diet in the field. For this reason, and because foraging activity is an important part of the ecological success of social insects, the present study aimed to investigate E. vizottoi's foraging strategies and dietary habits. First, we determined how abiotic factors constrained E. vizottoi's foraging patterns in the field by monitoring the foraging activity of 16 colonies on eight different days across two seasons. Second, we characterized E. vizottoi's diet by monitoring another set of 26 colonies during peak foraging activity. Our results show that E. vizottoi has foraging strategies that are similar to those of congeneric species. In spite of having a low efficiency index, colonies adopted strategies that allowed them to successfully obtain food resources while avoiding adverse conditions. These strategies included preying on other ant species, a foraging tactic that could arise if a wide variety of food items are not available in the environment or if E. vizottoi simply prefers, regardless of resource availability, to prey on other invertebrates and especially on other ant species.

Preservation of honey bee (Apis mellifera L., Hymenoptera: Apidae) sperm, coupled with instrumental insemination, is an effective strategy to protect the species and their genetic diversity. Our overall objective is to develop a method of drone semen preservation; therefore, two experiments were conducted. Hypothesis 1 was that cryopreservation (-196 °C) of drone semen is more effective for long-term storage than at 16 °C. Our results show that after 1 yr of storage, frozen sperm viability was higher than at 16 °C, showing that cryopreservation is necessary to conserve semen. However, the cryoprotectant used for drone sperm freezing, dimethyl sulfoxide (DMSO), can harm the queen and reduce fertility after instrumental insemination. Hypothesis 2 was that centrifugation of cryopreserved semen to reduce DMSO prior to insemination optimize sperm quality. Our results indicate that centrifuging cryopreserved sperm to remove cryoprotectant does not affect queen survival, spermathecal sperm count, or sperm viability. Although these data do not indicate that centrifugation of frozen-thawed sperm improves queen health and fertility after instrumental insemination, we demonstrate that cryopreservation is achievable, and it is better for long-term sperm storage than above-freezing temperatures for duration of close to a year. © The Authors 2017.

Effect of host and food availability on the biological characteristics of Trichogramma galloi Zucchi (Hymenoptera, Trichogrammatidae). Biological characteristics of Trichogramma galloi Zucchi, 1988 were evaluated in laboratory where these parasitoids were reared on eggs of Diatraea saccharalis (Lepidoptera, Pyralidae) with or without honey, and exposed to eggs of the host after 0, 6, 12, 24, 36, 48, 60, 72 and 84 hours of emergence. The parasitism rate and viability showed higher for individuals that received food. The sex ratio was not influenced by food. The number of individuals per egg only showed difference for those adults that did not receive food and stayed six hours without the host eggs. Checking the effect of the availability of eggs, only the sex ratio, with or without honey, did not show differences. The results show that T. galloi needs a carbohydrate supply and the time can influence the reproductive capacity. (author)

Guidelines for Clinical Practice: Hymenoptera sting allergy in children: 2017 update

Science.gov (United States)

2017-10-01

Las picaduras por himenópteros son frecuentes en la infancia. La mayoría producen reacciones locales, consecuencia de un mecanismo inflamatorio, no alérgico, no tienen progresión y se resuelven con simples medidas terapéuticas. Las reacciones más extensas, generalmente, están asociadas a mecanismos alérgicos, mediados por inmunoglobulina E. Su máxima expresión, la anafilaxia, presenta síntomas cutáneos, respiratorios, cardiovasculares, digestivos y/o neurológicos, con riesgo de muerte. La prevalencia de anafilaxia en pacientes con mastocitosis sistémica es más alta. La familia Hymenoptera, que incluye hormigas coloradas, abejas y avispas, es la causante de las picaduras de mayor riesgo, potencialmente fatales. Los pilares del diagnóstico son la historia clínica, la identificación del insecto, y las pruebas diagnósticas cutáneas y/o in vitro interpretadas por el especialista en Alergia e Inmunología. La inmunoterapia con veneno es el tratamiento de elección para prevenir reacciones anafilácticas por picaduras de himenópteros.

Abstract. Weather can be treated as an important factor in the nesting pattern of several solitary wasps species. Nesting pattern of wasp Monobia angulosa Saussure (Vespidae: Eumeninae was accessed in present study in the agricultural area of Mucugê-Ibicoara, Chapada Diamantina, Bahia, during an extended period of dry season. In here we also presented the first record of a natural nest in pre-existing cavities prior used by Xylocopa (Neoxylocopa cearensis Ducke (Apidae: Xylocopinae. For a description of the M. angulosa’s natural nest a single nest found in apple orchard (Malus domestica Borkh was used. For the nesting pattern study we used the trap nests technique with 25 points along the agricultural sampled area; traps were placed in remaining native vegetation. Each sample point was at least 4 km apart. Emerged in the laboratory a total of 19 females and 23 males for a total of 19 established nests, males emerged prior females. Unlike the horizontal trap nests, the natural one was built in vertical linear series and a wooden stake was used as a substrate. Nesting concentrated in the warmer months, between February and April, 2012, with very low precipitation, evidencing influence on nesting pattern of this species, probably due fast response to climatic changes.

Temporal polyethism and worker specialization in the wasp, Vespula germanica.

Science.gov (United States)

Hurd, Christine R; Jeanne, Robert L; Nordheim, Erik V

2007-01-01

Temporal polyethism is a common mechanism of worker specialization observed in social insect species with large colony sizes, Vespula wasp colonies consist of thousands of monomorphic workers, yet studies based on small cohorts of workers report that temporal polyethism is either weak or completely absent in different Vespula species. Concerned that the small sample size of these studies precluded detection of temporal polyethism, several hundred, known-age Vespula germanica (F.) (Hymenoptera: Vespidae) workers were studied. High variability was found in the sequence and diversity of tasks workers perform, suggesting that V. germanica colonies exhibit weak temporal polyethism. The most common order in which tasks were taken up was 1) nest work, 2) pulp foraging, 3) carbohydrate foraging, and 4) protein foraging. However, only 61% of the wasps performed more than two of the tasks during their lives. Thorax size had a significant negative effect on the age at first foraging, but the magnitude of the effect was small. The daily ratio of task generalists to specialists was relatively constant despite the high turnover of workers, growth of the colony, and the colony's transition from rearing worker larvae to rearing reproductives. Over the course of their lives, 43% of the workers averaged more than one kind of task performed per day. Life history traits are identified that may explain why vespines with large colonies use a generalist strategy of labor division rather than the specialist strategy observed in honey bees (Apis mellifera) and large colonies of wasps (Polybia occidentalis).

Full Text Available Host stage preference, functional response and mutual interference of Diaeretiella rapae (McIntosh (Hymenoptera: Braconidae: Aphidiinae on Diuraphis noxia (Mordvilko (Hemiptera: Aphididae were investigated under defined laboratory conditions (20±1°C; 60±5% relative humidity; 16 h light/8 h dark photoperiod. Nicholson’s model and linear regression were used to determine per capita search-efficiency and the interference coefficient, respectively. There was a significant difference between the rates of parasitism on different stages of D. noxia. The highest parasitism percentage was observed on the third instar nymphs of D. noxia in both choice and no-choice preference tests. Results of logistic regression revealed a type II functional response. The estimated values of search-efficiency (a and handling time (Th were 0.072 h-1 and 0.723 h, respectively. The maximum attack rate was calculated to be 33.22. The per capita search-efficiency decreased from 0.011 to 0.004 (h-1 as parasitoid densities increased from 1 to 8. Therefore, different host-parasitoid ratios can affect the efficacy of D. rapae.

Establishment of a closed population honey bee, Apis mellifera L. (Hymenoptera: Apidae), breeding program based on 'black' strains has been proposed for eastern Australia. Long-term success of such a program requires a high level of genetic variance. To determine the likely extent of genetic variation available, 50 colonies from 11 different commercial apiaries were sequenced in the mitochondrial cytochrome oxidase I and II intergenic region. Five distinct and novel mitotypes were identified. No colonies were found with the A. mellifera mellifera mitotype, which is often associated with undesirable feral strains. One group of mitotypes was consistent with a caucasica origin, two with carnica, and two with ligustica. The results suggest that there is sufficient genetic diversity to support a breeding program provided all these five sources were pooled.

Full Text Available Abstract Background Swarm-founding epiponine wasps are an intriguing group of social insects in which colonies are polygynic (several queens share reproduction and differentiation between castes is often not obvious. However, caste differences in some may be more pronounced in later phases of the colony cycle. Results Using morphometric analyses and multivariate statistics, it was found that caste differences in Metapolybia docilis are slight but more distinct in latter stages of the colony cycle. Conclusions Because differences in body parts are so slight, it is proposed that such variation may be due to differential growth rates of body parts rather than to queens being larger in size, similar to other previously observed epiponines.

Wolbachia in two populations of Melittobia digitata Dahms (Hymenoptera: Eulophidae)

Copeland, Claudia S.; Sivinski, John

2008-01-01

We investigated two populations of Melittobia digitata Dahms, a gregarious parasitoid (primarily upon a wide range of solitary bees, wasps, and flies), in search of Wolbachia infection. The first population, from Xalapa, Mexico, was originally collected from and reared on Mexican fruit fly pupae, Anastrepha ludens Loew (Diptera: Tephritidae); the other, from Athens, Georgia, was collected from and reared on prepupae of mud dauber wasps, Trypoxylon politum Say (Hymenoptera: Crabronidae). PCR studies of the ITS2 region corroborated that both parasitoid populations were the same species; this potentially provides a useful molecular taxonomic profile since females of Melittobia species are superficially similar. Amplification of the Wolbachia surface protein gene (wsp) confirmed the presence of this endosymbiont in both populations. Sequencing revealed that the Wolbachia harbored in both populations exhibited a wsp belonging to a unique subgroup (denoted here as Dig) within the B-supergroup of known wsp genes. This new subgroup of wsp may either belong to a different strain of Wolbachia from those previously found to infect Melittobia or may be the result of a recombination event. In either case, known hosts of Wolbachia with a wsp of this subgroup are only distantly related taxonomically. Reasons are advanced as to why Melittobia - an easily reared and managed parasitoid - holds promise as an instructive model organism of Wolbachia infection amenable to the investigation of Wolbachia strains among its diverse hosts.

Full Text Available Nematus oligospilus Förster (Hymenoptera: Tenthredinidae is a willow sawfly native to the Northern Hemisphere which became a serious defoliator in willow plantations (Salix spp. of the Southern Hemisphere after being introduced in the early 1980´s. Studies on host preferences provide useful information for the development of pest management strategies where the willow sawfly may produce tree damage and economic loss. Feeding preferences of N. oligospilus larvae were evaluated in laboratory trials by simultaneously offering leaves from four willow tree clones commonly used in commercial plantations in Argentina (Salix babylonica var sacramenta Hortus, Salix nigra Marsch., S. babylonica L. x Salix alba L. 131-27 and Salix matsudana Koidz. x S. alba L. 13-44. Larvae of N. oligospilus fed on leaves from the four clones. However, insects consumed a significantly higher proportion of S. babylonica var sacramenta leaves than of leaves from the other clones. Results indicate that all clones used in the trials were palatable to the insect, and that S. babylonica var sacramenta is the preferred host for larval herbivory.Nematus oligospilus Förster (Hymenoptera: Tenthredinidae, o la avispa sierra de los sauces, es nativa del Hemisferio Norte y se ha convertido en un serio defoliador en plantaciones de sauces (Salix spp. del Hemisferio Sur, después de su introducción a principios de 1980.

Lariophagus distinguendus Förster (Hymenoptera: Pteromalidae) has been suggested as a biological control agent against the granary weevil, Sitophilus granarius (L.), in grain stores. Information on the effect of low temperatures prevailing in grain stores is necessary to be able to predict...... the potential of this parasitoid against S. granarius in temperate regions, where grain is cooled with ambient air to achieve safe storage conditions. The influence of constant temperatures of 16, 18, and 20°C on life table parameters and parasitoid-induced mortality (PIM) was investigated in the laboratory. L...... is quicker than that of its host, estimated from the literature; and it kills many hosts in addition to those used for reproduction....

Effect of host and food availability on the biological characteristics of Trichogramma galloi Zucchi (Hymenoptera, Trichogrammatidae). Biological characteristics of Trichogramma galloi Zucchi, 1988 were evaluated in laboratory where these parasitoids were reared on eggs of Diatraea saccharalis (Lepidoptera, Pyralidae) with or without honey, and exposed to eggs of the host after 0, 6, 12, 24, 36, 48, 60, 72 and 84 hours of emergence. The parasitism rate and viability showed higher for individuals that received food. The sex ratio was not influenced by food. The number of individuals per egg only showed difference for those adults that did not receive food and stayed six hours without the host eggs. Checking the effect of the availability of eggs, only the sex ratio, with or without honey, did not show differences. The results show that T. galloi needs a carbohydrate supply and the time can influence the reproductive capacity. (author)

This paper deals with the description of two new species of Horismenus Walker (Hymenoptera: Eulophidae) from Brazil, parasitoids of larvae of Adetus analis (Haldeman) (Coleoptera: Cerambycidae). Both species are similar to Horismenus steirastomae (Girault), a species that also parasitizes cerambycids. Adetus analis is a pest of Sechium edule (Jacq.) Swartz (Cucurbitaceae), a minor crop in Brazil, Argentina and U.S.A., but also feeds in stems of Pereskia aculeata Miller (Cactaceae), an ornamental plant that has become a problematic weed species in Africa, where it was introduced. The two new Horismenus species are described, diagnosed, and compared to H. steirastomae.

Fertility signals in the bumblebee Bombus terrestris (Hymenoptera: Apidae)

2008-06-01

In eusocial Hymenoptera, queen control over workers is probably inseparable from the mechanism of queen recognition. In primitively eusocial bumblebees ( Bombus), worker reproduction is controlled not only by the presence or absence of a dominant queen but also by other dominant workers. Furthermore, it was shown that the queen dominance is maintained by pheromonal cues. We investigated whether there is a similar odor signal released by egg-laying queens and workers that may have a function as a fertility signal. We collected cuticular surface extracts from nest-searching and breeding Bombus terrestris queens and workers that were characterized by their ovarian stages. In chemical analyses, we identified 61 compounds consisting of aldehydes, alkanes, alkenes, and fatty acid esters. Nest-searching queens and all groups of breeding females differed significantly in their odor bouquets. Furthermore, workers before the competition point (time point of colony development where workers start to develop ovaries and lay eggs) differed largely from queens and all other groups of workers. Breeding queens showed a unique bouquet of chemical compounds and certain queen-specific compounds, and the differences toward workers decrease with an increasing development of the workers’ ovaries, hinting the presence of a reliable fertility signal. Among the worker groups, the smallest differences were found after the competition point. Egg-laying females contained higher total amounts of chemical compounds and of relative proportions of wax-type esters and aldehydes than nest-searching queens and workers before the competition point. Therefore, these compounds may have a function as a fertility signal present in queens and workers.

Nestling mortality in the endangered and endemic Hihi, also called Stitchbird (Notiomystis cincta), was studied over the 2008-09 breeding season at Zealandia-Karori Sanctuary, Wellington, New Zealand. Histopathology showed traumatic ventriculitis in seven of 25 (28%) dead nestlings. Single or multiple granulomas centered on chitinous insect remnants were found lodged within the gizzard mucosa, muscle layers, and ventricular or intestinal serosa. The insect remnants were confirmed as bee or wasp stings (Hymenoptera) using light and electron microscopy. Bacteria or yeasts were also found in some granulomas, and death was due to bacterial septicemia in four cases. Endemic New Zealand birds are likely to lack evolutionary adaptations required to safely consume introduced honey bees (Apis mellifera) and vespulid wasps (Vespula germanica [German wasp], and Vespula vulgaris [common wasp]). However, these insects are attracted to feeding stations used to support translocated Hihi populations. As contact between bees, wasps, and the endemic fauna of New Zealand seems inevitable, it may be necessary to minimize the numbers of these introduced insects in areas set aside for ecologic restoration.

Full Text Available Black ants, Dolichoderus thoracicus (Smith (Hymenoptera: Formicidae is one of the biological agents that can be used to control the cocoa pod borer Conopomorpha cramerella and Helopeltis sp. To effectively prevent C. cramerella infestation, high population of black ants are required. Population growth of black ants in three types of permanent nests and non permanent nest were observed during 3 months. Every month, five nests of each type were taken at random and then all stadia were calculated. The permanent nests will support ant population for some years and the black ant population per nest is higher when compared to nest made of dried cocoa leaves only. Permanent nests are made of 75 pieces of dried cocoa leaves which are placed in plastic bags with ventilation holes. In the longer term permanent black ant nests are more cost effective then ant nests which have been made from only dried leaves because frequent replacement is not required. Permanent ant nests will also ensure a stable black ant population is maintained.

Absence of complementary sex determination in the parasitoid wasp genus Asobara (Hymenoptera: Braconidae.

Directory of Open Access Journals (Sweden)

Wen-Juan Ma

Full Text Available An attractive way to improve our understanding of sex determination evolution is to study the underlying mechanisms in closely related species and in a phylogenetic perspective. Hymenopterans are well suited owing to the diverse sex determination mechanisms, including different types of Complementary Sex Determination (CSD and maternal control sex determination. We investigated different types of CSD in four species within the braconid wasp genus Asobara that exhibit diverse life-history traits. Nine to thirteen generations of inbreeding were monitored for diploid male production, brood size, offspring sex ratio, and pupal mortality as indicators for CSD. In addition, simulation models were developed to compare these observations to predicted patterns for multilocus CSD with up to ten loci. The inbreeding regime did not result in diploid male production, decreased brood sizes, substantially increased offspring sex ratios nor in increased pupal mortality. The simulations further allowed us to reject CSD with up to ten loci, which is a strong refutation of the multilocus CSD model. We discuss how the absence of CSD can be reconciled with the variation in life-history traits among Asobara species, and the ramifications for the phylogenetic distribution of sex determination mechanisms in the Hymenoptera.

Colony size evolution and the origin of eusociality in corbiculate bees (Hymenoptera: Apinae.

Directory of Open Access Journals (Sweden)

Enrique Rodriguez-Serrano

Full Text Available Recently, it has been proposed that the one of the main determinants of complex societies in Hymenoptera is colony size, since the existence of large colonies reduces the direct reproductive success of an average individual, given a decreased chance of being part of the reproductive caste. In this study, we evaluate colony size evolution in corbiculate bees and their relationship with the sociality level shown by these bees. Specifically i the correlation between colony size and level of sociality considering the phylogenetic relationship to evaluate a general evolutionary tendency, and ii the hypothetical ancestral forms of several clades within a phylogeny of corbiculate bees, to address idiosyncratic process occurring at important nodes. We found that the level of social complexity in corbiculate bees is phylogenetically correlated with colony size. Additionally, another process is invoked to propose why colony size evolved concurrently with the level of social complexity. The study of this trait improves the understanding of the evolutionary transition from simple to complex societies, and highlights the importance of explicit probabilistic models to test the evolution of other important characters involved in the origin of eusociality.

Hyposoter didymator (Thunberg) (Hymenoptera: Ichneumonidae) is a koinobiont endoparasitoid that emerges from the parasitization of economically important noctuid pests. H. didymator also is considered one of the most important native biocontrol agents of noctuids in Spain. Side effects of five insecticides with very different modes of action (fipronil, imidacloprid, natural pyrethrins + piperonyl butoxide, pymetrozine, and triflumuron) at the maximum field recommended rate in Spain were evaluated on H. didymator parasitizing Spodoptera littoralis (Boisduval) larvae and pupae of the endoparasitoid. Parasitized larvae were topically treated or ingested treated artificial diet. Parasitoid cocoons were topically treated. Host mortality when parasitized larvae were treated, as well as further development of the parasitoid surviving (e.g., percentage of cocoons spun, adult emergence, hosts attacked, and numbered progeny) were determined. Toxicity after treatment of parasitized larvae differed depending on the mode of exposure and insecticide. Fipronil was always highly toxic; imidacloprid killed all host insects by ingestion, but it was less toxic to both host and parasitoids, when administered topically; natural pyrethrins + piperonyl butoxide and triflumuron showed differing degrees of toxicity, and pymetrozine was harmless. Parasitoid cocoons provided effective protection against all the insecticides, except fipronil.

We conducted research to examine the potential impacts ofcoumaphos, fluvalinate, and Apilife VAR (Thymol) on drone honey bee, Apis mellifera L. (Hymenoptera: Apidae), sperm viability over time. Drones were reared in colonies that had been treated with each miticide by using the dose recommended on the label. Drones from each miticide treatment were collected, and semen samples were pooled. The pooled samples from each treatment were subdivided and analyzed for periods of up to 6 wk. Random samples were taken from each treatment (n = 6 pools) over the 6-wk period. Sperm viability was measured using dual-fluorescent staining techniques. The exposure of drones to coumaphos during development and sexual maturation significantly reduced sperm viability for all 6 wk. Sperm viability significantly decreased from the initial sample to week 1 in control colonies, and a significant decrease in sperm viability was observed from week 5 to week 6 in all treatments and control. The potential impacts of these results on queen performance and failure are discussed.

The biology of the 10 species of Leucophora (Diptera: Anthomyiidae) recorded in the Neotropics remains unknown. The large majority of the studied species so far are kleptoparasites of bees and wasps. Here, we report the first observations of Leucophora andicola (Bigot) and Leucophora peullae (Malloch) visiting the nests of ground-nesting sweat bees Corynura (Hymenoptera: Halictidae) in Chilean Patagonia. Females of both species perch on small stones or sticks within a dense nest aggregation of the bees and then track pollen-loaded bees in flight with great precision, eventually following them into their nests. The overall behavior closely resembles that observed for many other species of the genus. Excavations of some bee nests returned only two dipteran puparia, possibly of Leucophora, suggesting a low parasitism rate. One male of L. peullae was also collected at the bee aggregation. This is the first report of host association for any Leucophora from the Neotropics and the first report of any anthomyiid fly associated with augochlorine bees.

2016-03-27

Supplemental feeding of honey bee (Apis melliferaL., Hymenoptera: Apidae) colonies in spring is essential for colony buildup in northern apicultural regions. The impact of pollen and syrup feeding on drone production and sperm quality is not well-documented, but may improve fecundation of early-bred queens. We measured the impact of feeding sucrose syrup, and protein supplements to colonies in early spring in eastern Canada. Drones were reared under different nutritional regimes, and mature individuals were then assessed in regard to size, weight, and semen quality (semen volume, sperm count, and viability). Results showed significant increases in drone weight and abdomen size when colonies were fed sucrose and a protein supplement. Colonies receiving no additional nourishment had significantly less semen volume per drone and lower sperm viability. Our study demonstrates that feeding honey bee colonies in spring with sucrose syrup and a protein supplement is important to enhance drone reproductive quality. RÉSUMÉ: L'administration de suppléments alimentaires aux colonies de l'abeille domestique (Apis melliferaL., Hymenoptera: Apidae) au printemps est essentielle pour le bon développement des colonies dans les régions apicoles nordiques. L'impact de la supplémentation des colonies en pollen et en sirop sur la production des faux-bourdons et la qualité du sperme demeure peu documenté mais pourrait résulter en une meilleure fécondation des reines produites tôt en saison. Nous avons mesuré l'impact de la supplémentation en sirop et/ou en supplément de pollen sur les colonies d'abeilles tôt au printemps dans l'est du Canada. Les faux-bourdons ont été élevé sous différents régimes alimentaires et les individus matures ont ensuite été évalués pour leur taille, leur poids ainsi que la qualité de leur sperme (volume de sperme, nombre et viabilité des spermatozoïdes. Les résultats montrent une augmentation significative du poids et de la taille

In the context of the modern agriculture, pest control is important in order to increase productivity in maize (Zea mays L.). However, this control should be done rationally, prioritising environmentally safer methods such as biological control. This paper aims to report the occurrence of Dolichozele koebelei Viereck, 1911 (Hymenoptera: Braconidae) in Spodoptera frugiperda (J. E. Smith, 1797) (Lepidoptera: Noctuidae) larvae collected in maize subjected to different cropping systems. The experiment was conducted at the Centro Nacional de Pesquisa de Milho e Sorgo (CNPMS) in Sete Lagoas, Minas Gerais State, Brazil, using organic and conventional production. Ten plants were sampled from each of the 24 plots and for each production system, three times a week during the entire cycle of maize (variety BR 106). In the laboratory, larvae were distributed in individual rearing containers with artificial diet until the end of the biological cycle. An increased number of S. frugiperda larvae was observed in organic single crop maize; hence a higher percentage of S. frugiperda larvae parasitised by Hymenoptera and Diptera also occurred in the maize under this production system. Dolichozele koebelei had not yet been described in association with larvae of S. frugiperda. The percentage of parasitism of S. frugiperda larvae was high in both experiments, indicating the importance of natural control agents in reducing the population density of S. frugiperda, and especially the importance of an appropriate crop management.

Vespula vulgaris is an invasive scavenging social wasp that has very recently arrived in Patagonia (Argentina), a territory previously invaded ? 35 yrs earlier ? by another wasp, Vespula germanica. Although V. vulgaris wasps possess features that could be instrumental in overcoming obstacles through several invasion stages, the presence of preestablished populations of V. germanica could affect their success. We studied the potential role played by V. germanica on the subsequent invasion proc...

Predation is probably the most important male mortality factor in insect species with courtship displays that render males performing them conspicuous targets of predators. Sexually active Mediterranean fruit fly males, Ceratitis capitata (Wied.), aggregate in leks, where they participate in agonistic encounters and engage in visual, acoustic and pheromone-calling displays to attract receptive females. The objective of this study was to assess: a) whether sexually displaying C. capitata males in leks inside host and non-host foliage are subject to predation by the most prominent predators yellow-jacket wasps, Vespula germanica (F.), and if so, b) whether olfactory, visual or auditive stimuli are used by foraging wasps in locating male C. capitata prey. Studies were carried out in a citrus orchard and surroundings on the island of Chios, Greece. Observations were conducted using perforated containers hung within mulberry, fig or citrus foliage. Living C. capitata flies of different sex and either mature or immature were placed inside. Our results show that the yellowjacket wasps have learned to associate the presence of sexually active medfly males aggregated in leks with their prey's pheromone (kairomone). Foraging wasps, flying through the crowns of host trees, responded to the odour source of C. capitata male pheromone by approaching from downwind. Even inside dense citrus tree foliage, wasps keyed in on aggregations of pheromone-calling males using olfactory stimuli. Stimuli of visual and acoustic male signalling were only used at close range, after having followed the pheromone plume close to its source. Visual cues played a greater role in directing wasp foraging under more open and exposed host foliage conditions. Odour-based foraging of wasps inside host foliage in the mid-morning hours, when medfly male lekking activities peak, shifted gradually to a more visual-based host fruit patrolling in the afternoons to capture ovipositing and feeding medfly females. On ripe fruit, particularly fig, V. germanica visual prey hunting also included the capture of feeding medfly males, other feeding Diptera, as well as medfly larvae extracted from wasp-made perforations in the fruit.

Vespula vulgaris is an invasive scavenging social wasp that has very recently arrived in Patagonia (Argentina), a territory previously invaded - 35 yrs earlier - by another wasp, Vespula germanica Although V. vulgaris wasps possess features that could be instrumental in overcoming obstacles through several invasion stages, the presence of preestablished populations of V. germanica could affect their success. We studied the potential role played by V. germanica on the subsequent invasion process of V. vulgaris wasps in Patagonia by focusing on the foraging interaction between both species. This is because food searching and exploitation are likely to overlap strongly among Vespula wasps. We carried out choice tests where two types of baits were presented in a pairwise manner. We found experimental evidence supporting the hypothesis that V. germanica and V. vulgaris have an asymmetrical response to baits with stimuli simulating the presence of each other. V. germanica avoided baits with either visual or olfactory cues indicating the V. vulgaris presence. However, V. vulgaris showed no preference between baits with or lacking V. germanica stimuli. These results suggest that the presence of an established population of V. germanica may not contribute to added biotic resistance to V. vulgaris invasion. © The Author 2016.

Determination of Hymenoptera venom (HV)-specific serum IgE antibodies is a useful diagnostic method in patients with systemic anaphylactic reaction (SAR) to Hymenoptera stings. In a general population cohort, we determined the prevalence of SAR and HV-specific IgE antibodies and assessed parameters associated with the latter. A total of 277 voluntarily participating inhabitants of rural Bavaria (Germany) (232 adults, mean age 38.0 years; 45 children, mean age 8.4 years) were investigated for a history of atopic disease or SAR to insect stings; in 258 of these, total IgE and specific IgE antibodies to HV (Apis mellifera, Vespula vulgaris/germanica) and four common aeroallergens (birch pollen, grass pollen, house-dust mite, and cat dander) in the serum were determined. Nine (3.3%) subjects reported SAR to insect stings. In 27.1% of the sera, specific IgE antibodies to HV were found, to bee venom in 24.8%, and to wasp venom in 8.5% (P 100 kU/l was found in 22.5%. Specific serum IgE to HV was significantly associated with male sex (female vs. male, OR = 0.47; CI 0.25-0.86), young age (children vs. adults, OR = 2.80; CI 1.25-6.28), a history of SAR to insect stings (OR = 4.16; CI 1.15-15.03), total sIgE > 100 kU/l (OR = 3.88; CI 1.98-7.60), and specific IgE antibodies to three of the four aeroallergens (grass pollen, OR = 7.24 CI 3.66-14.38; birch pollen, OR = 3.67 CI 1.54-8.81; and house-dust mite, OR = 4.61 CI 2.08-10.32). It is concluded that immunologic sensitization to HV is common in the general population and is associated with atopy-related humoral IgE hyperresponsiveness.

The Braconidae, a family of parasitic wasps, constitute a major taxonomic challenge with an estimated diversity of 40,000 to 120,000 species worldwide, only 18,000 of which have been described to date. The skeletal morphology of braconids is still not adequately understood and the terminology is partly idiosyncratic, despite the fact that anatomical features form the basis for most taxonomic work on the group. To help address this problem, we describe the external skeletal morphology of Opius dissitus Muesebeck 1963 and Biosteres carbonarius Nees 1834, two diverse representatives of one of the least known and most diverse braconid subfamilies, the Opiinae. We review the terminology used to describe skeletal features in the Ichneumonoidea in general and the Opiinae in particular, and identify a list of recommend terms, which are linked to the online Hymenoptera Anatomy Ontology. The morphology of the studied species is illustrated with SEM-micrographs, photos and line drawings. Based on the examined species, we discuss intraspecific and interspecific morphological variation in the Opiinae and point out character complexes that merit further study. PMID:22558068

Full Text Available Braconidae is a highly diversified family of Hymenoptera and usually known by their role in biological control both in agricultural and natural ecosystems. Despite of that, little is known about its diversity in the Amazon region. The present work inventoried the braconid fauna of an Open Ombrophylous Forest with Palm Trees of the Parque Natural Municipal de Porto Velho, RO. Insects were collect from June/2008 to May/2009 using six Malaise traps in different parts of the reserve. A total of 377 wasps were captured, 17 subfamilies and 56 genera identified. Braconinae, Microgastrinae, Doryctinae and Rogadinae subfamilies were very abundant, and also the genera Aleiodes, Bracon, Capitonius, Compsobracon, Heterospilus, Hymenochaonia, Opius, Pedinotus, Rogas and Stantonia. The calculated Shannon diversity index was 2.15 and 3.3 for subfamily and genera, respectively, which were, generally, higher than the values found for other regions in Brazil. Generally, parasitoids were more abundant during the rainy season. The present work contributes with new genera records and faunistic data of Braconidae in Rondonia State, western Amazon.

The European wasp, Vespula germanica (Fabricius) (Hymenoptera: Vespidae), is of Palaearctic origin, being native to Europe, northern Africa and Asia, and introduced into North America, Chile, Argentina, Iceland, Ascension Island, South Africa, Australia and New Zealand. Due to its polyphagous nature and scavenging behaviour, V. germanica threatens agriculture and silviculture, and negatively affects biodiversity, while its aggressive nature and venomous sting pose a health risk to humans. In areas with warmer winters and longer summers, queens and workers can survive the winter months, leading to the build-up of large nests during the following season; thereby increasing the risk posed by this species. To prevent or prepare for such unwanted impacts it is important to know where the wasp may be able to establish, either through natural spread or through introduction as a result of human transport. Distribution data from Argentina and Australia, and seasonal phenology data from Argentina were used to determine the potential distribution of V. germanica using CLIMEX modelling. In contrast to previous models, the influence of irrigation on its distribution was also investigated. Under a natural rainfall scenario, the model showed similarities to previous models. When irrigation is applied, dry stress is alleviated, leading to larger areas modelled climatically suitable compared with previous models, which provided a better fit with the actual distribution of the species. The main areas at risk of invasion by V. germanica include western USA, Mexico, small areas in Central America and in the north-western region of South America, eastern Brazil, western Russia, north-western China, Japan, the Mediterranean coastal regions of North Africa, and parts of southern and eastern Africa.

The direct comparison between children and adults with Hymenoptera venom anaphylaxis (HVA) has never been extensively reported. Severe HVA with IgE-documented mechanism is the recommendation for venom immunotherapy, regardless of age. To determine the differences in the basic diagnostic profile between children and adults with severe HVA and its practical implications. We reviewed the medical records of 91 children and 121 adults. Bee venom allergy was exposure dependent, regardless of age (P bee venom allergic group, specific IgE levels were significantly higher in children (29.5 kU A /L; interquartile range, 11.30-66.30 kU A /L) compared with adults (5.10 kU A /L; interquartile range, 2.03-8.30 kU A /L) (P venom were higher in bee venom allergic children compared with the wasp venom allergic children (P venom. At concentrations lower than 0.1 μg/mL, 16% of wasp venom allergic children and 39% of bee venom allergic children had positive intradermal test results. The median tryptase level was significantly higher in adults than in children for the entire study group (P = .002), as well as in bee (P = .002) and wasp venom allergic groups (P = .049). The basic diagnostic profile in severe HVA reactors is age dependent. Lower skin test reactivity to culprit venom in children may have practical application in starting the intradermal test procedure with higher venom concentrations.

CA Barbieri Junior

Full Text Available This study sampled the diversity of Braconidae (Hymenoptera in three different ecosystems: a degraded pasture, a secondary forest and an area in recovery process using native tree seedlings. The objective was to verify the use of those insects as a tool to check the local conservation by examining Shannon's diversity index. Ten subfamilies were identified, and Microgastrinae was predominant in a number of individuals. The diversity index calculated varies among the sampled areas, thus showing a correlation with vegetation cover with the number of individuals collected and number of subfamilies found. The results showed changes in the community of Braconidae, in the recovery area between the first and second year of study, thereby leading to the conclusion that they are indicators of environmental quality.

The use of insecticides, herbicides, and fungicides commonly occurs in mixtures in tanks in order to control phytosanitary problems in crops. However, there is no information regarding the effects of these mixtures on non-target organisms associated to the rice agroecosystem. The aim of this study was to know the toxicity of pesticide tank mixtures from rice crops against Telenomus podisi Ashmead (Hymenoptera: Platygastridae). Based on the methods adapted from the International Organisation for Biological and Integrated Control of Noxious Animals and Plants (IOBC), adults of T. podisi were exposed to residues of insecticides, herbicides, and fungicides, individually or in mixture commonly used by growers, in laboratory and on rice plants in a greenhouse. The mixture between fungicides tebuconazole, triclyclazole, and azoxystrobin and the mixture between herbicides cyhalofop-butyl, imazethapyr, imazapyr/imazapic, and penoxsulam are harmless to T. podisi and can be used in irrigated rice crops without harming the natural biological control. The insecticides cypermethin, thiamethoxam, and bifenthrin/carbosulfan increase the toxicity of the mixtures in tank with herbicides and fungicides, being more toxic to T. podisi and less preferred for use in phytosanitary treatments in the rice crop protection.

Full Text Available The potential of using gamma and ultraviolet radiation as an alternative treatment to increase the efficiency of Trichogramma euproctidis (Girault 1911 (Hymenoptera: Trichogrammatidae was investigated in the laboratory. The developmental and adult stages of T. euproctidis were exposed to gamma radiation of different doses (0-30 Gy and ultraviolet radiation of 254 nm wavelengths (UV-C for different durations (0-10 min to assess their effect on each of the instars and their potential in breaking the developmental cycle of the egg parasitoid. The LD50 values for eggs, prepupae, pupae and adults were 8.1, 10.0, 22.7 and 9.5 Gy for gamma radiation and 9.5, 0.12, 2.0 and 11.9 min for UV radiation, respectively. The pupa and adult stages were more radioresistant to both gamma and UV radiation. The most interesting and unexpected result obtained for the prepupal stage was that UV radiation has a greater effect on prepupal stages than gamma radiation.

Full Text Available Six species of Anastatus Motschulsky, 1859 (Hymenoptera: Eupelmidae were described from China in Chinese by J.K. Sheng and coauthors in 1997 and 1998: A. dexingensis, A. flavipes, A. fulloi, A. huangi, A. meilingensis and A. shichengensis. This represents almost half the species of Anastatus recorded from China, but no keys were given to differentiate the species and the original descriptions included only simple line drawings to illustrate the species. Because recognition of these species is critical prior to clarifying the Anastatus fauna of China and of the eastern Palaearctic and Oriental regions, we have redescribed the six species in detail in English based on original type material, illustrating the species through macrophotography of type material and providing a key to differentiate females of the species.

Através da fotointerpretação e de trabalhos de campo, delimitaram-se áreas com erosão laminar, erosão laminar e sulco raso, erosão em sulco profundo e ravina, e erosão em ravina profunda e voçoroca. Foram mapeadas quatro grandes voçorocas conectadas à rede de drenagem, oito extensas ravinas parcialmente vegetadas e diversas ravinas médias obliteradas, porém instáveis pela retomada da erosão. Há predominância de sulcos profundos e ravinas nas baixas vertentes em contato com a baixada fluvial e no talvegue das principais bacias de captação da drenagem pluvial.

Full Text Available En Hymenoptera, los niveles de sociabilidad han sido asociados a rasgos conductuales, tales como los comportamientos de nidificación y agonísticos, y la capacidad de reconocimiento entre conespecíficos. El reconocimiento de compañeros de nido es un fenómeno de amplia difusión entre especies eusociales, y puede ser inferido por el resultado de las interacciones agonísticas entre hembras; estas son más tolerantes hacia compañeras de nido que hacia no compañeras de nido. Contrariamente, en la mayor parte de las especies solitarias las hembras son agresivas hacia otras hembras conespecíficas. En especies eusociales, la descendencia inmadura es alimentada directamente por la madre, o por obreras; así, el contacto frecuente entre progenie y hembras adultas puede contribuir a entender el reconocimiento social. En el extremo opuesto, las especies solitarias construyen nidos que no permiten interacciones entre adultos e inmaduros. A pesar de esto, estudios recientes sugieren que el aprendizaje del fenotipo propio podría explicar la capacidad de reconocimiento y, tal vez, corresponde al punto de partida en el desarrollo y evolución de la sociabilidad. La subfamilia Xylocopinae (Apidae ha emergido como un valioso modelo para estudiar la evolución de la sociabilidad pues contiene especies que presentan un amplio rango de sociabilidad. En particular, la tribu Manueliini representa un taxón interesante desde el punto de vista de la evolución de la sociabilidad en Xylocopinae pues ha sido propuesto como el grupo hermano de todos los demás Xylocopinae, es un taxón relicto que retiene rasgos morfológicos ancestrales, contiene solo especies fundamentalmente solitarias (aunque en una de estas se ha demostrado recientemente reconocimiento de compañeras de nido y de parientes y algunas especies exhiben rasgos conductuales precursores de vida social. En este trabajo se revisa en Hymenoptera los grados de sociabilidad asociados con rasgos

Full Text Available Com o estudo histórico das mudanças corporativas e tecnológicas vividas pelos médicos paulistas na década de 1930 pretende-se identificar como se deram as alterações no campo dos equipamentos e saberes com o surgimento das especialidades, que levou a mudanças e a rearranjos corporativos diante dos dilemas trazidos pelo governo de Getúlio Vargas e sua política centralizadora de poder. Apontam-se lastros, de ordem simbólica e representativa, alçados por médicos considerados 'antigos' e aqueles que representavam os 'novos' tempos da medicina, evidenciando-se os embates entre essas correntes com relação ao movimento de especialização e aos marcos particulares da história de São Paulo.Through the historical study of the corporate and technological changes experienced by doctors in São Paulo in the 1930s, we intend to identify how changes in the fields of equipment and knowledge came from the emergence of specialties, which led to corporate changes and rearrangements in the face of the dilemmas introduced by the Getúlio Vargas government and its policy of centralizing power. Connections are pointed out of a symbolic and representative order, backed by doctors considered 'old-school' and those that represented the 'new' times in medicine, evidencing the clashes between these currents vis-à-vis the specialization movement and particular landmarks in the history of São Paulo.

Full Text Available In the context of the modern agriculture, pest control is important in order to increase productivity in maize (Zea maysL.. However, this control should be done rationally, prioritising environmentally safer methods such as biological control. This paper aims to report the occurrence of Dolichozele koebelei Viereck, 1911 (Hymenoptera: Braconidae in Spodoptera frugiperda(J. E. Smith, 1797 (Lepidoptera: Noctuidae larvae collected in maize subjected to different cropping systems. The experiment was conducted at the Centro Nacional de Pesquisa de Milho e Sorgo (CNPMS in Sete Lagoas, Minas Gerais State, Brazil, using organic and conventional production. Ten plants were sampled from each of the 24 plots and for each production system, three times a week during the entire cycle of maize (variety BR 106. In the laboratory, larvae were distributed in individual rearing containers with artificial diet until the end of the biological cycle. An increased number of S. frugiperda larvae was observed in organic single crop maize; hence a higher percentage of S. frugiperda larvae parasitised by Hymenoptera and Diptera also occurred in the maize under this production system. Dolichozele koebelei had not yet been described in association with larvae of S. frugiperda. The percentage of parasitism of S. frugiperda larvae was high in both experiments, indicating the importance of natural control agents in reducing the population density of S. frugiperda, and especially the importance of an appropriate crop management.

Full Text Available Social wasps are important for the study of social behavior evolution because their colonies present different degrees of caste differentiation, from morphologically similar to highly conspicuous, associated with the occasional presence of intermediate females, which bears developed ovaries but no insemination. In the Polistinae, depending on the taxon, such differentiation can be discreet or conspicuous. This work intended to study morphological and physiological differences between castes in Protopolybia chartergoides by using morphometric analyses associated with multivariate statistical analyses and physiological evaluations from females' ovarian development. Results evidence low morphological and physiological differences among the castes in P. chartergoides, indicating three groups of females: queens, workers and intermediates. In this way, it was possible to suggest that Protopolybia chartergoides presents post-imaginal caste differentiation (or a very subtle form of pre-imaginal determination.Vespas sociais são importantes para o estudo da evolução do comportamento social devido suas colônias apresentarem diferentes graus de diferenciação de castas, de morfologicamente similares às altamente conspícuas, associadas com a presença de fêmeas intermediárias, as quais desenvolvem seus ovários, mas não estando inseminadas. Nos Polistinae, tais diferenciações podem ser discretas ou conspícuas. Este trabalho teve como objetivo estudar as diferenças morfológicas e fisiológicas entre as castas de Protopolybia chartergoides pelo uso de análises morfométricas associada com análises estatísticas multivariadas e avaliações fisiológicas do desenvolvimento ovariano das fêmeas. Os resultados mostraram baixa diferenciação morfológica e fisiológica entre as castas de P. chartergoides, indicando a presença de três grupos de fêmeas: rainhas, operárias e intermediárias. Assim, foi possível sugerir que Protopolybia chartergoides apresenta diferenciação de casta pós-imaginal (ou uma forma muito sutil de determinação pré-imaginal.

Full Text Available Drosophila melanogaster Meigen, 1830 has served as a model insect for over a century. Sequencing of the 11 additional Drosophila Fallen, 1823 species marks substantial progress in comparative genomics of this genus. By comparison, practically nothing is known about the genome size or genome sequences of parasitic wasps of Drosophila. Here, we present the first comparative analysis of genome size and karyotype structures of Drosophila parasitoids of the Leptopilina Förster, 1869 and Ganaspis Förster, 1869 species. The gametic genome size of Ganaspis xanthopoda (Ashmead, 1896 is larger than those of the three Leptopilina species studied. The genome sizes of all parasitic wasps studied here are also larger than those known for all Drosophila species. Surprisingly, genome sizes of these Drosophila parasitoids exceed the average value known for all previously studied Hymenoptera. The haploid chromosome number of both Leptopilina heterotoma (Thomson, 1862 and L. victoriae Nordlander, 1980 is ten. A chromosomal fusion appears to have produced a distinct karyotype for L. boulardi (Barbotin, Carton et Keiner-Pillault, 1979 (n = 9, whose genome size is smaller than that of wasps of the L. heterotoma clade. Like L. boulardi, the haploid chromosome number for G. xanthopoda is also nine. Our studies reveal a positive, but non linear, correlation between the genome size and total chromosome length in Drosophila parasitoids. These Drosophila parasitoids differ widely in their host range, and utilize different infection strategies to overcome host defense. Their comparative genomics, in relation to their exceptionally well-characterized hosts, will prove to be valuable for understanding the molecular basis of the host-parasite arms race and how such mechanisms shape the genetic structures of insect communities.

Stingless bee colonies typically consist of one single-mated mother queen and her worker offspring. The stingless bee Melipona bicolor (Hymenoptera: Apidae) shows facultative polygyny, which makes this species particularly suitable for testing theoretical expectations concerning social behavior. In this study, we investigated the social structure and genetic relatedness among workers from eight natural and six manipulated colonies of M. bicolor over a period of one year. The populations of M. bicolor contained monogynous and polygynous colonies. The estimated genetic relatedness among workers from monogynous and polygynous colonies was 0.75 ± 0.12 and 0.53 ± 0.16 (mean ± SEM), respectively. Although the parental genotypes had significant effects on genetic relatedness in monogynous and polygynous colonies, polygyny markedly decreased the relatedness among nestmate workers. Our findings also demonstrate that polygyny in M. bicolor may arise from the adoption of related or unrelated queens.

Most barley cultivars have some degree of resistance to the wheat stem sawfly (WSS), Cephus cinctus Norton (Hymenoptera: Cephidae). Damage caused by WSS is currently observed in fields of barley grown in the Northern Great Plains, but the impact of WSS damage among cultivars due to genetic differences within the barley germplasm is not known. Specifically, little is known about the mechanisms underlying WSS resistance in barley. We characterized WSS resistance in a subset of the spring barley CAP (Coordinated Agricultural Project) germplasm panel containing 193 current and historically important breeding lines from six North American breeding programs. Panel lines were grown in WSS infested fields for two consecutive years. Lines were characterized for stem solidness, stem cutting, WSS infestation (antixenosis), larval mortality (antibiosis), and parasitism (indirect plant defense). Variation in resistance to WSS in barley was compared to observations made for solid-stemmed resistant and hollow-stemmed susceptible wheat lines. Results indicate that both antibiosis and antixenosis are involved in the resistance of barley to the WSS, but antibiosis seems to be more prevalent. Almost all of the barley lines had greater larval mortality than the hollow-stemmed wheat lines, and only a few barley lines had mortality as low as that observed in the solid-stemmed wheat line. Since barley lines lack solid stems, it is apparent that barley has a different form of antibiosis. Our results provide information for use of barley in rotation to control the WSS and may provide a basis for identification of new approaches for improving WSS resistance in wheat.

O pós-abolição e suas dinâmicas de sociabilidade: lógicas familiares e relações interpessoais no oeste paulista cafeeiro

Full Text Available Tomando como foco o município de São Carlos, um dos principais centros da economia cafeeira do oeste paulista durante a virada do século XIX para o XX, o artigo analisa as tensões presentes nas relações interpessoais tecidas entre negros, de um lado, e fazendeiros e pequenos proprietários rurais, de outro. Por meio da leitura de dois inquéritos policiais da época, percebeu-se que essas relações eram mediadas por determinados códigos morais, os quais, por sua vez, delimitavam certas normas de sociabilidade. Quando alguns destes códigos eram quebrados, as situações de conflito se potencializavam. Pode-se afirmar que, se a proximidade com pessoas de posse ainda era, para a população negra do pós-abolição, uma das principais fontes para obtenção de recursos materiais e simbólicos, as relações de poder inscritas nesses vínculos não deixavam de produzir contestações quanto às identificações e hierarquias encerradas no âmbito familiar. De modo geral, acredita-se que as disputas de poder presentes nessas interações podem estar relacionadas à renegociação, trazida pelo fim do escravismo, de determinadas formas de distinção social.

This paper records the first report of Megastigmus transvaalensis Hussey (Hymenoptera: Torymidae) in Brazilian peppertree, Schinus terebinthifolius Raddi (Anacardiaceae) drupes in Sorocaba, state of São Paulo, Brazil. This wasp is an invasive species and was found damaging S. terebinthifolius drupes in urban areas (35.0 ± 15.8%), natural forests (21.5 ± 10.2%) and restoration areas (15.8 ± 8.4%). The bio-ecology and damage caused by M. transvaalensis in the S. terebinthifolius drupes warrants further study focused upon the management of this phytophagous wasp. Megastigmus transvaalensis has a potential to be disseminated throughout Brazil and is posing a threat to the natural regeneration of S. terebinthifolius in the native forests and restoration areas and ecological regions of this country.

Mosaicism may explain the evolution of social characters in haplodiploid Hymenoptera with female workers.

2010-12-01

The role of haplodiploidy in the evolution of eusocial insects and why in Hymenoptera males do not perform any work is presently unknown. We show here that within-colony conflict caused by the coexistence of individuals of the same caste expressing the same character in different ways can be fundamental in the evolution of social characters in species that have already reached the eusocial condition. Mosaic colonies, composed by individuals expressing either the wild-type or a mutant phenotype, inevitably occurs during the evolution of advantageous social traits in insects. We simulated the evolution of an advantageous social trait increasing colony fitness in haplodiploid and diplodiploid species considering all possible conditions, i.e. dominance/recessivity of the allele determining the new social character, sex of the castes, and influence of mosaicism on the colony fitness. When mosaicism lowered colony fitness below that of the colony homogeneous for the wild type allele, the fixation of an advantageous social character was possible only in haplodiploids with female castes. When mosaicism caused smaller reductions in colony fitness, reaching frequencies of 90% was much faster in haplodiploids with female castes and dominant mutations. Our results suggest that the evolution of social characters is easier in haplodiploid than in diplodiploid species, provided that workers are females.

The evolutionary dynamics of major regulators for sexual development among Hymenoptera species

Directory of Open Access Journals (Sweden)

Matthias eBiewer

2015-04-01

Full Text Available All hymenopteran species, such as bees, wasps and ants, are characterized by the common principle of haplodiploid sex determination in which haploid males arise from unfertilized eggs and females from fertilized eggs. The underlying molecular mechanism has been studied in detail in the western honey bee Apis mellifera, in which the gene complementary sex determiner (csd acts as primary signal of the sex determining pathway, initiating female development by csd-heterozygotes. Csd arose from gene duplication of the feminizer (fem gene, a transformer (tra ortholog, and mediates in conjunction with transformer2 (tra2 sex-specific splicing of fem. Comparative molecular analyses identified fem/tra and its downstream target doublesex (dsx as conserved unit within the sex determining pathway of holometabolous insects. In this study, we aim to examine evolutionary differences among these key regulators. Our main hypothesis is that sex determining key regulators in Hymenoptera species show signs of coevolution within single phylogenetic lineages. We take advantage of several newly sequenced genomes of bee species to test this hypothesis using bioinformatic approaches. We found evidences that duplications of fem are restricted to certain bee lineages and notable amino acid differences of tra2 between Apis and non-Apis species propose structural changes in Tra2 protein affecting co-regulatory function on target genes. These findings may help to gain deeper insights into the ancestral mode of hymenopteran sex determination and support the common view of the remarkable evolutionary flexibility in this regulatory pathway.

The pink hibiscus mealybug (PHM), Maconellicoccus hirsutus (Green) (Hemiptera: Pseudococcidae) and the associated hymenopterous parasitoid, Anagyrus kamali Moursi, 1948 (Hymenoptera: Encyrtidae), are reported for the first time in Brazil. Specimens of the PHM were collected on nine hosts plants, Annona muricata L. (Anonnaceae), Glycine max (L.) Merr. (Fabaceae), Centrolobium paraensis Tul. (Fabaceae), Inga edulis Mart. (Fabaceae), Hibiscus rosa-sinensis L. (Malvaceae), Psidium guajava L. (Myrtaceae), Averrhoa carambola L. (Oxalidaceae), Citrus sinensis (L.) Osbeck (Rutaceae) and Solanum lycopersicum L. (Solanaceae), in four municipalities in the north-northeast of the state of Roraima. The plants C. paraensis, I. edulis and C. sinensis are recorded for the first time as a hosts for PHM. Characteristic injuries observed on the host plants infested by PHM and suggestions for its management are presented.

Full Text Available The interactions of ectosymbiotic Laboulbeniales (Ascomycota fungi and their hosts are rather understudied. Rickia wasmannii Cavara is a common ant-associated Laboulbeniales species that has been reported in 17 countries of Europe, and frequently infects Myrmica scabrinodis Nylander, 1846 (Hymenoptera: Formicidae, a common ant species host, in high density. These make M. scabrinodis and R. wasmannii appropriate model organisms for studies on fungal host-ectosymbiont interactions. Aggressiveness and boldness of infected and uninfected M. scabrinodis workers from northern and eastern Hungary were studied in two laboratory-established behavioural experiments. Infected workers were significantly less aggressive and less bold (i.e. less likely to leave nest shelters than the uninfected ones. These results suggest that R. wasmannii has considerable effects on the behaviour of M. scabrinodis. Our study brings an evidence that infection of ants with Laboulbeniales might negatively affect the workers’ behaviour. In special, the competitive abilities might be affected most by these fungi, since remaining inside and behaving submissively is not effective behaviour in the case of significant competition for resources among colonies.

Full Text Available The community of orchid bees (Hymenoptera: Apidae: Euglossina was studied at an area in the transition between the Cerrado and Atlantic Forest biomes, from March, 2010 to February, 2011 in the Barroso region, state of Minas Gerais, eastern Brazil. Orchid-bee males were collected with bait traps containing three different scents (cineole, eugenol and vanillin and with entomological nets for collecting bees on flowers. A total of 614 orchid-bee males were collected using aromatic traps, belonging to four genera and 15 species. Twenty-five female specimens belonging to two genera and at least three species were collected on flowers. Eulaema (Apeulaema nigrita Lepeletier, 1841 was the most abundant species (50% of collected specimens, followed by Euglossa (Euglossa truncata Rebêlo & Moure, 1996 (28%. Cineole was the most attractive compound (66.5% of males and 13 species, followed by eugenol (16% and 9 species and vanillin (13.5% and 4 species. Eulaema (Apeulaema marcii Nemésio, 2009 and Eufriesea auriceps (Friese, 1899 were attracted to all scents, whereas Euglossa species were collected only in cineole and eugenol.
