Full Text Available The Ibero-Balearic collection of Meloidae Gyllenhal, 1810 (Coleoptera, Tenebrionoidea of the Museu de Ciències Naturals de Barcelona A commented catalogue of the Ibero-Balearic collection of Meloidae Gyllenhal, 1810 housed in the Museu de Ciències Naturals de Barcelona is presented. The studied material consists of 2,129 specimens belonging to 49 of 64 species from the Iberian peninsula and the Balearic Islands. The temporal coverage of the collection extends from the last decades of the nineteenth century to the present time. Revision, documentation, and computerization of the material have been made, resulting in 963 collection records (June 2014. For each lot, the catalogue includes the register number, geographical data, collection date, collector or origin of the collection, and number of specimens. Information about taxonomy and distribution of the species is also given. Chorological novelties are provided, extending the distribution areas for most species. The importance of the collection for the knowledge of the Ibero-Balearic fauna of Meloidae is discussed, particularly concerning the area of Catalonia (northeastern Iberian peninsula as it accounts for 60% of the records. Some rare or particularly interesting species in the collection are highlighted, as are those requiring protection measures in Spain and Catalonia. The catalogue also shows a brief gallery of photographs that includes four type specimens.

Full Text Available The swimming behavior exhibited by specimens of L. fasciatus and O. uniformis was analyzed frame-by-frame with video observation recorded with a digital camera, attached to a stereomicroscope. Adults of O. uniformis, an aquatic insect, swim with all three pairs of legs. During the process of swimming the majority of the abdomen and rostrum remain submerged, part of the fore and hind tibiae remain above the surface, while the mid tibiae remain submerged. The mesothoracic legs, during the power-stroke stage, provide the greatest thrust while the metathoracic legs provide the least forward propulsion. The prothoracic legs, extended forward, help to direct the swimming. The semi-aquatic specie L. fasciatus shows the same swimming style as O. uniformis, that is, with movement of all the three pairs of legs; the mesothoracic legs are responsible for the main propulsion. The insect body remains on the water surface during the process of swimming, while the legs remain submerged. Both species complete a swimming cycle in 0.33 and 0.32 seconds, respectively, with an average speed of 1.38 cm/s and a maximum and minimum swimming duration time of 11.15 and 5.05 minutes, respectively, for L. fasciatus. The swimming behavior exhibited by O. uniformis and L. fasciatus corresponds to the style known as a breast strokelike maneuver. This is the first record of this kind of swimming for both species here observed and increases to seven the number of genera of Curculionidae exhibiting this behavior.O comportamento de nado exibido por indivíduos de L. fasciatus e O. uniformis foi analisado quadro a quadro através de imagens obtidas com o auxílio de uma câmera fotográfica digital com opção de vídeo, acoplada a um estereomicroscópio. Foi demonstrado que O. uniformis, espécie aquática, nada com o auxílio dos três pares de pernas. Durante este processo a maior parte do abdome e rostro localizam-se abaixo da superfície da água, parte das tíbias anteriores e posteriores acima da superfície, enquanto as médias permanecem submersas durante o nado. As pernas metatorácicas, durante a "braçada", impulsionam fracamente o inseto para frente, enquanto que as mesotorácicas são as responsáveis por uma maior propulsão. As pernas protorácicas, estendidas anteriormente, ajudam na orientação do nado. A espécie L. fasciatus, de hábito semi-aquático, apresenta o mesmo estilo de nado como em O. uniformis, também realizado com auxilio dos três pares de pernas, sendo as mesotorácicas, responsáveis pela maior propulsão. O corpo do inseto permanece na superfície da água durante todo o processo, porém as pernas encontram-se mergulhadas. Ambas as espécies, O. uniformis e L. fasciatus, completam um ciclo do nado em cerca de 0,33 e 0,32 segundos, respectivamente, com uma velocidade média de 1,38 cm/s e tempo máximo e mínimo de permanência de nado 11,15 e 5,05 minutos, respectivamente, para L. fasciatus. O comportamento de nado exibido por O. uniformis e L. fasciatus corresponde ao estilo de nado conhecido como manobra semelhante ao nado peito (breast strok-like maneuver. Trata-se do primeiro registro para ambas as espécies elevando para sete o número de gêneros de Curculionidae conhecidos com tal comportamento.

Full Text Available Evidence that terrestrial gastropods are able to detect chemical cues from their predators is obvious yet scarce, despite the scientific relevance of the topic to enhancing our knowledge in this area. This study examines the influence of cuticular extracts from predacious ground beetles (Carabus auratus, Carabus hispanus, Carabus nemoralis and Carabus coriaceus, and a neutral insect species (Musca domestica on the shelter-seeking behavior of naive slugs (Deroceras reticulatum. Slugs, known to have a negative phototactic response, were exposed to light, prompting them to make a choice between either a shelter treated with a cuticular extract or a control shelter treated with pure ethyl alcohol. Their behavioral responses were recorded for one hour in order to determine their first shelter choice, their final position, and to compare the percentage of time spent in the control shelters with the time spent in the treated shelters.The test proved to be very effective: slugs spent most of the experiment in a shelter. They spent significantly more time in the control shelter than in the shelter treated with either C. nemoralis (Z = 2.43; p = 0.0151; Wilcoxon matched-pairs signed-ranks test or C. coriaceus cuticular extracts (Z = 3.31; p<0.01; Wilcoxon matched-pairs signed-ranks test, with a seemingly stronger avoidance effect when presented with C. coriaceus extracts. The other cuticular extracts had no significant effect on any of the behavioral items measured. Although it cannot be entirely excluded that the differences observed, are partly due to the intrinsic properties of the vehicle employed to build the cuticular extracts, the results suggest that slugs can innately discriminate amongst different potential predators and adjust their behavioral response according to the relevance of the threat conveyed by their predator's chemical cues.

The antimicrobial properties of the pygidial gland secretions released by the adults of the three ground beetle species, Carabus ullrichii, C. coriaceus, and Abax parallelepipedus, have been tested. Microdilution method was applied for detection of minimal inhibitory concentrations (MICs), minimal bactericidal concentrations (MBCs), and minimal fungicidal concentrations (MFCs). Additionally, morpho-histology of the pygidial glands is investigated. We have tested 16 laboratory and clinical strains of human pathogens—eight bacterial both gram-positive and gram-negative species and eight fungal species. The pygidial secretion samples of C. ullrichii have showed the strongest antimicrobial effect against all strains of treated bacteria and fungi. Staphylococcus aureus, Lysteria monocytogenes, and Salmonella typhimurium proved to be the most sensitive bacterial strains. Penicillium funiculosum proved to be the most sensitive micromycete, while P. ochrochloron and P. verrucosum var . cyclopium the most resistant micromycetes. The pygidial secretion of C. coriaceus has showed antibacterial potential solely against Pseudomonas aeruginosa and antifungal activity against Aspergillus fumigatus, A. versicolor, A. ochraceus, and P. ochrochloron. Antibacterial properties of pygidial gland secretion of A. parallelepipedus were achieved against P. aeruginosa, while antifungal activity was detected against five of the eight tested micromycetes (A. fumigatus, A. versicolor, A. ochraceus, Trichoderma viride, and P. verrucosum var . cyclopium). Commercial antibiotics Streptomycin and Ampicillin and mycotics Ketoconazole and Bifonazole, applied as the positive controls, showed higher antibacterial/antifungal properties for all bacterial and fungal strains. The results of this observation might have a significant impact on the environmental aspects and possible medical purpose in the future.

This study was carried out in National Park Başkonuş Mountain (Kahramanmaraş, Turkey), in Mediterranean region from April to October of 2004 and 2005. A total 31 species of ground beetles (Coleoptera, Carabidae) were recorded in the pitfall traps. Among them, Carabus (Archicarabus) gotschi caramanus Fairmaire, 1886, Carabus (Procrustes) coriaceus mopsucrenae Peyron, 1858 and Nebria (Nebria) hemprichi Klug, 1832 were the most abundant species. Distribution, diversity and monthly distribution of species in steppes, forest edge and forest interior, and chorotypes and ecology of these species were separately given in this study. It was recorded that the diversity of ground beetles was significantly higher in the forest edge and steppes than in the forest interior. There was no significant difference in the diversity of ground beetles in the steppes and the forest edge.

The larvae and pupae of six species of the Palaearctic genus Sibinia Germar, 1817 are described in detail for the first time. Five of them develop in seeds of Caryophyllaceae and belong to Sibinia (s. str.): S. attalica Gyllenhal, 1835; S. femoralis Germar, 1824; S. tibialis Gyllenhal, 1835; and S. viscariae (Linnaeus, 1760), which are included in the S. femoralis group, and S. sicana Ragusa, 1908, which is included in the S. unicolor Fåhraeus, 1843 group. The sixth species is S. sodalis Germar, 1824, which develops in seeds of Plumbaginaceae and belongs to the subgenus Dichotychius Bedel, 1885. The larvae and pupae of these species are compared with those previously described for some species of the third subgenus, Microtychius Casey, 1910 from the Americas. Some larval characters, but no pupal ones, are useful to support the three subgenera and the two previously mentioned groups of Sibinia s. str., which were previously postulated based on a few adult morphological characters. The immatures of Sibinia are also compared with those of the closely related genus Tychius Germar, 1817, providing some distinctive characters between both genera. New bionomic data on larval and pupal development and adult emergence are reported for all the described species. These data suggest that species in this genus are highly homogeneous in life history traits.

The types of thirty-two nominal weevil species described by Johann Christian Fabricius are reviewed and lecto- and paralectotypes are designated for twenty-two of them. A neotype is designated for Curculiosticticus Fabricius, 1777. Protapionvaripes (Germar, 1817) is declared a nomen protectum over Curculioflavipes Fabricius, 1775. Based on a study of syntypes, Rhinomacercurculioides Fabricius, 1781 is confirmed as a member of Mycterus (Mycteridae), Bruchusundatus Fabricius, 1787 is tentatively transferred to Erotylidae, Curculiofulvirostris Fabricius, 1787 and Anthribusroboris Fabricius, 1798 are confirmed as members of Salpingus (Salpingidae), and Brachyceruscristatus Fabricius, 1798 is transferred to Tenebrionidae. Based on lectotype designation, Curculiocaninus Fabricius, 1792 is confirmed as a synonym of Sitonalineatus (Linnaeus, 1758) and Curculioinnocuus Fabricius, 1802 as a synonym of Cneorhinusbarcelonicus (Herbst, 1797). Bruchusrufipes Fabricius, 1792 is not considered an available species name, but a later use of Bruchusrufipes Olivier, 1790. Cossonusincisus Pascoe, 1885 is reinstated as valid from synonymy under Cossonusilligeri Champion, 1909 and Cossonusvulneratus Illiger, 1805 from synonymy under Cossonuscanaliculatus (Fabricius, 1792) (a primary homonym of Curculiocanaliculatus Olivier, 1791). Cossonuscanaliculatus Fabricius, 1802 is a secondary homonym of the former and is replaced with Cossonusincisus. Salpingusfulvirostris (Fabricius, 1787) is reinstated as valid from synonymy under Salpingusplanirostris (Fabricius, 1787), a primary homonym of Curculioplanirostris Piller & Mitterpacher, 1783. The following new combinations are proposed: Brachysomuserinaceus (Fabricius, 1802) (from Curculio), Bronchusferus (Gyllenhal, 1840) (from Hipporhinus), Bronchusglandifer (Fabricius, 1792) (from Curculio), Bronchusnivosus (Sparrman, 1785) (from Curculio), Bronchussparrmani (Gyllenhal, 1833) (from Hipporhinus), Coelocephalapionatrirostre (Fabricius, 1802

Full Text Available A survey conducted in central Italy found 126 species of phytophagous insects from five orders and 25 families on dyer’s woad, Isatis tinctoria L., a biennial or short-lived perennial. About 75% of the species found attacking this weed were polyphagous, 20% were restricted to the family Brassicaceae, and only 5% were restricted to the genus Isatis. Four of the one hundred twenty six species recovered were specific enough to merit further research as candidates for biological control of I. tinctoria L. in the United States. Preliminary host range tests were conducted for the weevils Ceutorhynchus rusticus Gyllenhal, Ceutorhynchus peyerimoffi Hustache, Aulacobaris fallax (H. Brisout, and the fleabeetle Psylliodes isatidis Heikertinger. All tests were conducted at the USDA-ARS-EBCL Rome substation from 2003 to 2006 and are reported herein.

Full Text Available It is reported the occurrence of coleoborers Cosmopolites sordidus (Germar, 1824, Metama- sius hemipterus (L., 1758, Metamasius canalipes (Gyllenhal, 1838 and Rhynchophorus palmarum (L., 1758 attacking banana cultivar 'Terra' (Musa paradisiaca (Musaceae, in the municipality of Joaquim Gomes, State of Alagoas. Twenty adult specimens were sent to Prof. Dr. Sergio Antonio Vanin, Department of Zoology, In- stitute of Biosciences, University of São Paulo and identified by morphological characteristics, being this the first report of M. canalipes and R. palmarum damaging the cultivar 'Terra’ in Brazil. Attack symptoms in the field are initially manifested by chlorosis, necrosis and fall of the lower leaves, the fruits did not develop satis- factorily and plants finished by fall over. As a result of infestation was observed the death of 70% of the plants evaluated in the area.
Immatures of Palaearctic species of the weevil genus Tychius (Coleoptera, Curculionidae): new descriptions and new bionomic data with an evaluation of their value in a phylogenetic reconstruction of the genus .
Skuhrovec, Jiří; Gosik, Rafał; Caldara, Roberto
Larvae of 14 species and pupae of 12 species of Palaearctic Tychius Germar, 1817 are described for the first time. Larvae and pupae of T.meliloti Stephens, 1831, T. squamulatus Gyllenhal, 1835 and T. quinquepunctatus (Linnaeus, 1758), are redescribed with addition of new characters. They belong to 10 of 22 groups of species assembled through adult morphological characters in this region and, like all other Tychius with known biology, the studied species live on Leguminosae Papilionoideae, belonging to the tribes Genisteae, Loteae, Galegeae, Trifolieae and Vicieae. Generally larvae, but not pupae, show a few characters useful to support some groupings previously postulated on adult morphology, and also suggest some phylogenetic relationships among groups although these are partly weak because of several clear parallelisms or convergences. One of the most numerous and better known group of species, the T. stephensi group living on Trifolieae, is supported by two distinctive larval character states, whereas all the other groups seem to be distinguishable from each other at least by a unique larval character state. New bionomic data concerning larval and pupal development and adult emergence are reported for all the described species. These data confirm that this genus is highly homogeneous in habits and times of development, with unique adaptive differences in adult emergence and overwintering according to the single or double seasonal flowering of the host plant. On the basis of morphological characters of immatures and adults, a possible concordance between the evolution of Tychius and that of their host plants is discussed.

Insect seed predation may vary depending on seed production. The present study considers the hypothesis that the rates of seed predation tend to be smaller in years of higher fruit production. Thus, we monitored the production of fruits and predation of seeds of the palm Syagrus romanzoffiana over 2 years in the Atlantic Forest (Parque Municipal da Lagoa do Peri, Florianópolis, SC, Brazil), between July 2006 and June 2008. Plots of 0.25 m(2) were fitted under 20 mother plants and fruits were monthly collected for assessment of abundance and seed predation. There was variation in fruit production between the 2 years and among reproductive plants. Predation rates were high and occurred in the predispersal phase by the Curculionidae Revena rubiginosa Boheman, Anchylorhynchus aegrotus Fahraeus, and Anchylorhynchus variabilis Gyllenhal. Seed predation by these species of Anchylorhynchus is first registered in the present study. In average, about 60% of the seeds monthly produced in the population tend to escape insect predation in year of high or low production, becoming available for recruitment. The predation rate was not related to the amount of fruits produced per reproductive plant. Also, different than expected, there was a positive relation between the rates of seed predation and the total of fruits produced monthly on the plots. Thus, no evidence for the satiation of insect seed predators was found in this study with S. romanzoffiana.

The tight association between ambient temperature (T) and metabolic rate (MR) is a common occurrence in ectotherms, but the determinants of this association are not fully understood. This study examined whether the relationship between MR and T is the same among individuals, as predicted by the Universal Temperature Dependence hypothesis, or whether this relationship differs between them. We used flow-through respirometry to measure standard MR and to determine gas exchange patterns for 111 individuals of three Carabidae species which differ in size (Abax ovalis, Carabus linnei and C. coriaceus), exposed to four different temperatures (ten individuals of each species measured at 6, 11, 16 and 21°C). We found a significant interaction between ln body mass and the inverse of temperature, indicating that in a given species, the effect of temperature on MR was weaker in larger individuals than in smaller individuals. Overall, this finding shows that the thermal dependence of MR is not body mass invariant. We observed three types of gas exchange patterns among beetles: discontinuous, cyclic and continuous. Additionally, the appearance of these patterns was associated with MR and T. Evolution in diverse terrestrial environments could affect diverse ventilation patterns, which accommodate changes in metabolism in response to temperature variation. In conclusion, explaining the variance in metabolism only through fundamental physical laws of thermodynamics, as predicted by the Universal Temperature Dependence hypothesis, appears to oversimplify the complexity of nature, ignoring evolutionary trade-offs that should be taken into account in the temperature - metabolism relationship.
