    Full Text Available The fungus Metarhizium anisopliae var. acridum, strain CG 423, was tested under field conditions against the gregarious grasshopper Rhammatocerus schistocercoides (Rehn (Orthoptera: Acrididae. Conidia formulated in a racemic mixture of soybean oil and kerosene were sprayed under field conditions using an ultralow-volume hand-held atomizer Ulva Plus adjusted to deliver 2.9 L/ha. Bands composed of 2nd instar nymphs were treated with either 5.0x10(12 or 1.0x10(13 viable conidia/ha. The number of insects in each band was estimated at day one following spraying and by the end of the field trial (15 to 16 days post-treatment. Reductions in population size reached, in average, 65.8% and 80.4% for bands treated with the higher and lower dosage, respectively. For both dosages, total mortality rates of insects collected at two days post-application, and kept in cages for 14 days under lab conditions, showed no significant differences as compared to that obtained with insects collected immediately after spraying. Healthy insects were fed to native grasses sprayed on the field with 1.0x10(13 viable conidia/ha. Mortality levels of the nymphs fed on grasses collected two and four days post-application were not affected when compared to nymphs fed on grasses collected immediately following application.

    Full Text Available The sporulation of the fungi Metarhizium anisopliae var. acridum and Beauveria bassiana in cadavers of the grasshopper Rhammatocerus schistocercoides was studied in dry and humid environments. Both fungi were equally virulent against R. schistocercoides. However, internally, M. anisopliae produced more conidia than B. bassiana at 53% and 75% relative humidity. Externally, there was no sporulation at 53% and 75% RH, and M. anisopliae produced more conidia than B. bassiana at 100% RH.

    Full Text Available The objective of this work was to study the genetic variability of the grasshopper Rhammatocerus schistocercoides (Orthoptera: Acrididae using RAPD analysis among individuals from three populations, one from Colombia and two from Brazil (Goiás and Mato Grosso States. Ninety scorable binary markers were obtained by fingerprinting with 11 oligonucleotide primers. Most of the polymorphism was attributed to 42 markers with variable frequency among the different populations. Although the existence of significant difference among populations (PO objetivo deste trabalho foi estudar a variabilidade genética do gafanhoto Rhammatocerus schistocercoides (Orthoptera: Acrididae por meio da análise de RAPD entre indivíduos de três populações, uma da Colômbia e duas do Brasil (Goiás e Mato Grosso. Noventa marcadores binários foram selecionados através de análise de polimorfismo com o uso de 11 oligonucleotídeos. A maior parte do polimorfismo observado foi atribuída a 42 marcadores com freqüência variável entre as diferentes populações. Apesar da existência de diferença significativa interpopulacional (P<0,0001, grande proporção da variabilidade genética foi detectada dentro das populações (87,7% da variação total. As distâncias entre as populações colombianas e brasileiras foram 0,12 (P<0,0001 e 0,18 (P<0,0001 para Goiás e Mato Grosso, respectivamente. A distância obtida entre Goiás e Mato Grosso foi 0,06 (P<0,0001. Estes dados indicam que as diferenças fenotípicas entre populações estão associadas principalmente às distâncias geográficas entre as populações do Brasil e a da Colômbia.

    Full Text Available Le criquet du Mato Grosso : l'agriculture est-elle responsable ?. Investigations through bibliographical references and among the local population provided a collection of documents and evidences showing without any doubt that Rhammatocerus schistocercoides (ReHN, 1906 [Orth. Acrididae Gomphocerinae] outbreaks in Mato Grosso (Brazil are not a new event neither by nature nor by magnitude. Therefore, the present conception on the origin of those outbreaks need to be drastically revised. The previous hypotheses, implying an overrated agricultural development of concerned areas since 1980, must then be rejected.

    Sachs, M; Encke, A


    The unusual course of Ludwig Rehn's professional development directed him from a general practitioner close to Frankfurt am Main to his convocation as first Professor in ordinary for surgery to the Frankfurt University, which was newly established in 1914. Among his numerous publications, especially the following contributed immensely to the development of modern surgery: in 1884, he already described the healing of patients with Graves' disease by subtotal resection of the goiter; in 1885 he first described the high prevalence of bladder tumors in workers of an aniline factory; in 1886, he managed the first successful heart-suture after a stab-incision of the right ventricle; in 1897, he already performed an operation at the thoracal oesophagus, with an access via the posterior mediastinum; in 1920, he established the operative treatment (pericardectomy) of patients with a calcified pericarditis (armour heart).

  11. Biolistic co-transformation of Metarhizium anisopliae var. acridum strain CG423 with green fluorescent protein and resistance to glufosinate ammonium. (United States)

    Inglis, P W; Aragão, F J; Frazão, H; Magalhães, B P; Valadares-Inglis, M C


    Metarhizium anisopliae var. acridum (syn. M. flavoviride) is recognized as a highly specific and virulent mycopathogen of locusts and grasshoppers and is currently being developed as a biological control agent for this group of insects in Brazil. Intact conidia of M. anisopliae var. acridum strain CG423 were transformed using microparticle bombardment. Plasmids used were: (1) pBARKS1 carrying the bar gene of Streptomyces hygroscopicus fused to the Aspergillus nidulans trpC promoter, encoding resistance to glufosinate ammonium (or phosphinothricin) and modified by addition of the telomeric repeat (TTAGGG)(18) of Fusarium oxysporum and 2.pEGFP/gpd/tel carrying a red-shifted variant gene for Aequorea victoria green fluorescent protein (EGFP) which we have fused to the A. nidulans gpd promoter and trpC terminator. Highly fluorescent co-transformants were selected on solid minimal medium containing 100 microg ml(-1) glufosinate ammonium using an inverted microscope with 450-490 nm excitation/510 nm emission filter set. Southern blot analysis of co-transformants revealed varying multiple chromosomal integrations of both bar and egfp genes at both telomeric and non-telomeric loci. Transformants retained pathogenicity in bioassays against Rhammatocerus schistocercoides and showed unaltered lack of pathogenicity against larvae of the non-target insect Anticarsia gemmatalis. One co-transformant from four tested, however, showed a significant, but non-dose-dependent, elevation in virulence against Tenebrio molitor.

  12. Sex ratios in juveniles and adults of Dichroplus maculipennis (Blanchard and Borellia bruneri (Rehn (Orthoptera: Acrididae

    Full Text Available Dichroplus maculipennis and Borellia bruneri are two of the 18 grasshopper species of actual or potential economic relevance as pests in Argentina. The objective of this study was to estimate the sex ratios for adults and older nymphs of D. maculipennis and B. bruneri in the field, and analyze possible temporal variations. The study was conducted during seven seasons (2005-06 to 2011-12 in representative plant communities of the southern Pampas region. A total of 4536 individuals of D. maculipennis, and 6038 individuals of B. bruneri were collected. The sex ratio registered in older nymphs for D. maculipennis and B. bruneri did not deviate from a 1:1 ratio (p > 0.05, suggesting that these species have such a primary sex ratio. However, a significant bias in sex composition in adults of both species was observed (p < 0.05. The sex ratio in adults of D. maculipennis was different in five of the 18 sampling dates carried out. In three sampling dates it was biased toward males, while in the other two it was biased toward females. Taking into account the sex ratio by sampling season, significant differences were recorded in two seasons. In 2007-08 the sex ratio was biased toward males (1 F:2.26 M, while in 2008-09 it was biased toward females (1.35 F:1 M. The sex ratio in adults of B. bruneri was always biased toward males (p < 0.05. We conclude that results obtained in this study indicate that various factors like differential survival, dispersion, predation, among others, could have modified the primary sex ratio in these species.

    This paper investigates the impact of interindustry wage distribution on structural change in the Swedish and US manufacturing sector in the 1970s. Structural change in the centralized Swedish labour market reacts far more positive to market pressures towards wage changes than structural change...... in the decentralized US labour market. Support for the Rehn-Meidner model of solidarity wages and structural change is found. It is shown how opposing ideologies and policy making influence not only the wage pattern but also industry structures of economies....

    Full Text Available ABSTRACT The number of studies on Neotropical mantises has been growing in recent years, and the systematics of Mantodea is now a dynamic field with noteworthy contributions. Several taxonomic revisions have been published recently. The taxonomy of Paraphotina Giglio-Tos, 1915 is reviewed as part of current studies on systematics of Neotropical Mantodea. Currently, Paraphotina contains four species from South America: P. caatingaensis (Menezes & Bravo, 2013 comb. nov., P. insolita (Rehn, 1941, P. occidentalis Lombardo, 1998 and P. reticulata (Saussure, 1871.

Elephantopus mollis H.B.K. (Asteraceae and Hyptis suaveolens Poit. (Lamiaceae comprised 50% of the diet. The diet breadth of A. dilecta was compared to that of other 11 grasshopper species of the same sub-family, with rarefaction curves. The number of plant species eaten by A. dilecta was greater than that of nine other grasshopper species of the same sub-family (Rhachicreagra spp. but was lower then two others (Microptylopteryx hebardi Rehn, 1905 and Rhachicreagra astytophallus Jago & Rowell, 1981. This results are discussed in view of the broad geographical range and possession of developed wings by A. dilecta, which contrasts with most Ommatolampinae grasshoppers.

    Rivera, Julio; Vergara-Cobián, Clorinda


    We present a preliminary checklist of the praying mantises (Insecta: Mantodea) of Peru. A total of 67 species are reported, nine of which constitute new records from that country. The following new nomenclatural procedures are introduced: Musoniella margharethae Battiston and Picciau, 2008 is transferred to Musonia as Musonia margharethae (Battiston and Picciau, 2008) (comb. n.), and Phyllovates brevicollis Orofino, Ippolito and Lombardo, 2006 is considered a new synonym (syn. n.) of Pseudovates peruviana (Rehn, 1911). A new genus, Piscomantis gen. n., is established to accommodate Galapagia peruana Beier, 1935, which is now referred to as Piscomantis peruana (Beier, 1935) (comb. n.). Ten species are removed from the Peruvian mantis fauna and two nomina nuda are proposed. An overview of the biogeography and ecology of Peruvian praying mantises is presented.

The study was conducted in an experimental field with eucalypt hybrids of Eucalyptus urophylla x Eucalyptus grandis (clones GG100, Eucalyptus urophylla x Eucalyptus grandis (H13 and of Eucalyptus urophylla x Eucalyptus camaldulensis (VM01. The plantation was established in three continuous blocks with 512 plants with 3 m x 2 m, in Cáceres municipality, Mato Grosso State, Brazil. Infestation of proscopiidae insects was detected two months after planting . The insects were collected for identification. The attacked trees were geo-referenced and the injuries were quantified. The spatial pattern of proscopiidae he attack was determinated using the location information of the damaged plants, which have been submitted to a quadrats analyses using Morisita and binomial dispersion indexes. All the collected insects have been identified as Tetanorhynchus smithi Rehn, 1904 (Orthoptera, Proscopiidae. The infestation differed significantly among the three eucalypts clones and aggregated spatial pattern of attack was observed. This is the first report of this species of proscopiidae in eucalyptus in Mato Grosso State.

  12. Empress Sissi and cardiac tamponade: an historical perspective. (United States)

    Meyer, Philippe; Keller, Pierre-Frédéric; Spodick, David H


    On September 10, 1898, Empress Elizabeth of Austria, known as Sissi, was stabbed with a stiletto knife in her chest by an Italian anarchist in Geneva, Switzerland, and died 1 hour later. The autopsy revealed a large clot in the pericardial sac due to a perforation of the left ventricular wall, and the report concluded, "Death was undoubtedly caused by a progressive and slow blood leak, sufficient to compress the heart and to suspend its functions." Since antiquity, wounds of the heart had been considered immediately fatal, until Paré observed a delayed death after a stab to the heart in the 16th century. The physiology of cardiac tamponade was then elucidated by Richard Lower in 1669. However, it was only in the 19th century that the main clinical features of cardiac tamponade were described and the first treatments attempted. Kussmaul identified its most important clinical hallmark, pulsus paradoxus, in 1873 and the term "tamponade of the heart" was coined for the first time by Rose in 1884. Romero and Larrey pioneered the open drainage of the pericardium early in the century, and Rehn performed the first successful surgical suture of a heart wound in 1896. In conclusion, logistics aside, medical knowledge at the end of the 19th century would have been theoretically sufficient to save the empress from death.

  13. Socialdemocracia y capital: las raíces neoclásicas del modelo sueco

    Full Text Available La socialdemocracia ha tenido en el Modelo Sueco su referente por antonomasia. Sin embargo, las raíces teóricas de esta experiencia histórica, lejos de implementar los principios típicos del keynesianismo, se asentaron sobre unas bases de marcado carácter neoclásico. A través del conocido como Modelo Rehn-Meidner, posteriormente afianzado por el llamado Modelo EFO, la socialdemocracia sueca estableció un marco de política fiscal y monetaria restrictiva en el que se desarrolló una política salarial solidaria cimentada en un poderoso sindicalismo y un sólido sistema corporativista de negociación colectiva centralizada. Así, mediante la paulatina igualación y la contención de los salarios, se buscaba estimular la productividad, mantener a raya los costes laborales y facilitar la concentración y la centralización del capital. El objetivo final era favorecer la competitividad del sector exportador sueco con el fin de asegurar una rentabilidad y un ritmo de acumulación adecuados.

    eggs. Haplopodini Günther, 1953 is re-established (rev. stat.) and comprises almost exclusively Caribbean genera previously placed in Hesperophasmatini by Bradley & Galil (1977) or Cranidiini by Zompro, (2004). Aploploides Rehn & Hebard, 1938, Diapherodes Gray, 1835, Haplopus Burmeister, 1838 and Paracranidium Brock, 1998 were misplaced in Cranidiini and are transferred to Haplopodini. On the basis of numerous morphological characters of the insects and eggs Hesperophasmatini is removed from Pseudophasmatidae: Xerosomatinae and re-transferred to its previous position in the subfamily Cladomorphinae sensu lato. A detailed newdiagnosis of Hesperophasmatini is presented, but is only provisional since the true diversity is as yet only fractionally known. The lack of a gula distinguishes Hesperophasmatini from all other tribes. The genus Laciphorus Redtenbacher, 1908 is removed from Hesperophasmatini and transferred to Diapheromeridae: Diapheromerinae: Diapheromerini. The new tribe Pterinoxylini n. trib. is established to contain only the type-genus Pterinoxylus Audinet-Serville, 1838. It is closely related and perhaps the sister taxon of Hesperophasmatini, with which it shares the presence of rough sensory areas on the probasisternum and profurcasternum. It differs from Hesperophasmatini and Haplopodini by the presence of a tympanal region (= stridulatory organ) in the alae of females and the alveolar eggs, which possess peripheral opercular and polar structures. Haplopodini is likely to be the sister group of Pterinoxylini n. trib. + Hesperophasmatini.        The tribe Haplopodini rev. stat. is revised at the species level and comprises eight almost exclusively Caribbean genera, four of which are newly described. All eight genera now contained in Haplopodini are described in detail, differentiated from their closest relatives and their relationships and systematic position within Haplopodini are discussed. Keys and maps showing their distributions are presented

  15. Influence of weather variables and plant communities on grasshopper density in the Southern Pampas, Argentina. (United States)

    de Wysiecki, María Laura; Arturi, Marcelo; Torrusio, Sandra; Cigliano, María Marta


    A study was conducted to evaluate the influence of weather (precipitation and temperature) and plant communities on grasshopper density over a 14-year period (1996-2009) in Benito Juárez County, Southern Pampas, Argentina. Total density strongly varied among plant communities. Highest values were registered in 2001 and 2003 in highly disturbed pastures and in 2002 and 2009 in halophilous grasslands. Native grasslands had the lowest density values. Seasonal precipitation and temperature had no significant effect on total grasshopper density. Dichroplus elongatus (Giglio-Tos) (Orthoptera: Acridoidea), Covasacris pallidinota (Bruner), Dichroplus pratensis Bruner, Scotussa lemniscata Stål, Borellia bruneri (Rehn) and Dichroplus maculipennis (Blanchard) comprised, on average, 64% of the grasshopper assemblages during low density years and 79% during high density years. Dichroplus elongatus, S. lemniscata and C. pallidinota were the most abundant species in 2001, 2002 and 2003, while D. elongatus, B. brunneri and C. pallidinota in 2009. Dichroplus elongatus and D. pratensis, mixed feeders species, were positively affected by summer rainfall. This suggests that the increase in summer precipitation had a positive effect on the quantity and quality forage production, affecting these grasshopper populations. Scotussa lemniscata and C. pallidinota were negatively affected by winter and fall temperature, possibly affecting the embryonic development before diapause and hatching. Dichroplus elongatus and D. pratensis were associated with highly disturbed pastures, S. lemniscata with pastures and B. bruneri and D. maculipennis with halophilous grasslands. Covasacris pallidinota was closely associated with halophilous grasslands and moderately disturbed pastures. Weather conditions changed over the years, with 2001, 2002 and 2003 having excessive rainfall while 2008 and 2009 were the driest years since the study started. We suggest that although seasonal precipitation and

  16. Risk perception as a driver for risk management policies (United States)

    Carmona, María; Mañez, María


    Risk is generally defined as the "combination of the probability of the occurrence of an event and its negative consequences" ( UNISDR, 2009). However, the perception of a risk differs among cultures regarding different features such as the context,causes, benefits or damage. Risk perception is the subjective valuation of the probability of an event happening and how concerned individuals or groups are with the consequences (Sjöberg, 2004). Our study is based on an existing framework for risk perception (Rehn and Rohrmann, 2000). We analyse the characteristics of the risk perception regarding extreme events (e.g.droughts) and how the perception of the group drives the action to manage the risk. We do this to achieve an overview of the conditions that let stakeholders join each other to improve risk management especially when governments are not reacting properly. For our research, attention is paid on risk perception of Multi-Sector Partnerships not taking into account the individual level of risk perception. We focus on those factors that make risk management effective and increase resilience. Multi-Sector Partnerships, considered as significant governance structures for risk management, might contribute to reduce vulnerability in prone areas to natural hazards and disasters. The Multi-Sector Partnerships used for our research are existing partnerships identified in the cases studies of the European project ENHANCE. We implement a survey to analyse the perception of risk in the case studies. That survey is based on the Cultural Theory (Douglas and Wildavsky, 1982)and the Protection Motivation Theory (Rogers, 1975). We analyse the results using the Qualitative-Comparative Analysis proposed by Ragin in 1987. The results show the main characteristics of a risk culture that are beneficial to manage a risk. Those characteristics are shaped by the perception of risk of the people involved in the partnership, which in turn shapes their risk management. Nevertheless, we

    Full Text Available Høy forekomst av kroniske sykdommer og stigende helseutgifter representerer i lys av den kommende eldrebølgenen stor samfunnsøkonomisk utfordring. Den negative helseutviklingen er i ferd med å bli et nasjonalt problem og må få konsekvenser for fremtidig norsk helsepolitikk. Fysisk inaktivitet er en livsstilsfaktor som er sterkt assosiert med lavt nivå av kondisjon, total dødelighet og død av hjerte- og karsykdom. Studier viser at selv en liten bedring i kondisjon forventes å gi betydelig økt forventet levealder og at individer som har et bra kondisjonsnivå har opptil 15 flere leveår med god helse hvor de er selvhjulpne. Økt fysisk aktivitet har en gunstig effekt på alle risikofaktorer for kronisk sykdom og tidlig død, og vi mener derfor at man bør legge til rette for å øke det generelle fysiske aktivitetsnivået i befolkningen og bedre kunnskapen om fysisk aktivitet. Økt fysisk aktivitet vil forventes å bedre folkehelsen ved å redusere sykdomsforekomst, medisinbruk og dødelighet samt øke arbeidsevnen i populasjonen, noe som igjen vil redusere de samfunnsøkonomiske utgiftene. For å lykkes med dette, har vi tatt initiativ til prosjektet ”Sør-Trøndelag Aktivitets-Relaterte Tiltak” (START, som er tenkt å være en koordinert populasjonsbasert samhandling for bedre helse gjennom økt fysisk aktivitet rettet mot alle lag i befolkningen, fra krybbe til grav. Målet er at START skal danne grunnlag for nasjonal implementering av tiltak slik at vi oppnår en helsepolitisk bærekraftig utvikling i årene som kommer.

    Full Text Available Introdução: Ferimentos cardíacos penetrantes já foram considerados letais e intratáveis. Homero fez a primeira descrição da morte de Sarpedon em A Ilíada, em 3000 a.C. Em 1883, Billroth afirmou em um Congresso Europeu de Cirurgia que "o cirurgião que tentar suturar um ferimento cardíaco deverá perder o respeito de seus colegas". Em 1897, Rehn apresentou o primeiro caso bem sucedido de cardiorrafia de ventrículo direito Cerca de 87% das lesões cardiovasculares são, em particular, oriundas de trauma penetrante. E, as lesões ventriculares são mais frequentes que as atriais Objetivo: Descrever a abordagem realizada no serviço para pacientes com ferimento por arma branca (FAB na zona de Ziedler, através da experiência de sete casos relatados em 7 anos Discutir a relevância da utilização do FAST (Focused Assesment with Sonography for Trauma na avaliação primária do protocolo ATLS (Advanced Trauma Life Support e a sequência de reavaliação, e analisar qual o melhor procedimento diagnóstico e terapêutico para cada apresentação clínica do paciente. Método: Realizou-se um estudo retrospectivo, descritivo e analítico de sete pacientes atendidos no pronto atendimento do Politrauma do Conjunto Hospitalar de Sorocaba. O conteúdo deste trabalho foi obtido através da revisão de prontuário e descrição cirúrgica, registro fotográficos, além de revisão da literatura. Resultados: A experiência do serviço mostra que a abordagem inicial descrita pelo ATLS é fundamental para guiar o atendimento ao ferido. Quando da realização do FAST na avaliação primária indicando ausência de líquido na janela pericárdica deve-se manter o paciente com FAB em zona de Ziedler na sala de urgência sendo assistido por profissionais capacitados. A necessidade de Tomografia Computadorizada com contraste demonstra-se relevante para os casos em que há FAST inconclusivo, ainda que com paciente estável. A amostra exibe um caso de
