“…The results of this study strongly suggest a defensive role for the blends emitted by the two species: (i) the chemicals were secreted only in response to disturbance 20 and (ii) many constituents are found in other heteropteran defensive secretions 2,21,22 and are known to have toxic, irritating or deterrent properties. 18,23 However, these results also suggest that some volatile constituents may have the role of sex pheromones, both because they were absent in nymphs (i.e., sexually immature individuals) and because of the differences detected between male and female adults, mainly in Phloeophana longirostris.…”

Phloea subquadrata and Phloeophana longirostris are subsocial species that differ from each other in their host plants and degrees of aggregation. Until recently, only ten low-molecular weight compounds, a sesquiterpene, and dimers of (E)-4-oxo-2-hexenal had been reported from the contents of P. subquadrata glands. Here, the main goal was to distinguish the volatile compounds released by adult males, adult females and nymphs of the two species. The analyses revealed 103 compounds, of which 44 were exclusive to Phloeophana longirostris and 15 were exclusive to Phloea subquadrata. The data were analyzed by chemometric methods, which discriminated the phloeid species by developmental stage and sex. (E)-2-Hexenal, (E)-4-oxo-2-hexenal and (E)-2-octenal were found in both species. Adult individuals were characterized by the presence of methyl 2-methylbutanoate, (E)-2-hexenyl acetate and 2-hexenyl butanoate, and nymphs were characterized by 5-ethyl-2(3H)-furanone and (E)-2-octenal. There was chemical distinction between volatiles of adults and nymphs of the two species studied.

“…The morphology of the immature stages and some biological aspects of these two Chinavia species have already been reported (Grazia et al, 1982, Schwertner et al, 2002, and a preliminary laboratory study showed that C. impicticornis and C. ubica have similar development time, high fecundity (Laumann et al, 2006), and an efficient intraspecific communication during the reproductive stage, by means of chemical and vibratory signals (Moraes et al, 2005(Moraes et al, , 2008.…”

-The objective of this work was to compare the biology of Chinavia impicticornis and C. ubica (Hemiptera: Pentatomidae), two species of stinkbugs that occur as secondary pests in soybean. Life table procedures were used for evaluating nymphs, and fecundity tables for evaluating adults, in order to establish the demographics of the two species. The two species have similar demographic parameters, and the development of immature stages, from egg to adult, had similar duration periods of approximately 30 days. In both species, eggs and second-instar nymphs were the stages with higher mortality. Total egg production did not differ between females of both species. Fecundity and survival curves for adults showed similar trends in both species. However, C. ubica had greater potential to increase its populations, since its fecundity parameters were significantly higher than those of C. impicticornis. Moreover, the generational time and the time required to double the population size were shorter in C. ubica. Prolonged longevity, long oviposition period, high fecundity, and the ability to rapidly increase their populations indicate that both species can become potential pests in favorable environments.Index terms: Glycine max, age-specific fecundity, life table, mass rearing, reproductive potential, stinkbugs. Biologia comparada de dois percevejos congenéricos, Chinavia impicticornise C. ubica (Hemiptera: Pentatomidae)Resumo -O objetivo deste trabalho foi comparar a biologia de Chinavia impicticornis e de C. ubica (Hemiptera: Pentatomidae), duas espécies de percevejos que ocorrem como pragas secundárias em soja. Foram utilizados procedimentos de tabelas de vida para a avaliação de ninfas, e tabelas de fertilidade para a de adultos, no intuito de estabelecer os parâmetros demográficos das duas espécies. As duas espécies apresentam parâmetros demográficos similares, e o desenvolvimento dos estágios imaturos, de ovo a adulto, apresentou duração similar, de aproximadamente 30 dias. Nas duas espécies, ovos e ninfas do segundo instar foram os estágios com maior mortalidade. A produção total de ovos não diferiu entre as fêmeas de ambas as espécies. As curvas de fecundidade e de sobrevivência para adultos mostraram tendências semelhantes nas duas espécies. Entretanto, C. ubica apresentou maior potencial de aumentar suas populações, uma vez que seus parâmetros de fecundidade foram significativamente maiores do que os de C. impicticornis. Além disso, o tempo generacional e o tempo necessário para dobrar a população em tamanho foram mais curtos em C. ubica. A longevidade prolongada, o longo período de oviposição, a alta fertilidade e a capacidade de aumentar rapidamente suas populações indicam que ambas as espécies podem tornar-se pragas potenciais, em ambientes favoráveis.Termos para indexação: Glycine max, fecundidade por idade, tabela de vida, criação em massa, potencial reprodutivo, percevejos.

“…Tibraca limbativentris is a pest of paddy rice in Argentina, Brazil, and Uruguay, and the coreid ("leaf-footed bug") Leptoglossus zonatus damages corn and other plantations in Brazil. The pheromone chemistry of Heteroptera has been reviewed comprehensively 46 and also with a focus on neotropical species, 47 and here we will only refer to examples which are within the scope of the present review.…”

As pesquisas com feromônios de insetos tem uma longa e rica história, construída, primariamente, pelos estudos conduzidos no hemisfério Norte. Não é surpresa que estes estudos tenham apontado, em grande parte, para espécies relevantes dessas regiões do mundo, na maioria pragas agrícolas e florestais. As investigações com feromônios nos países da América do Sul vieram somente algumas décadas atrás, apesar da sua forte dependência agrícola e, conseqüentemente, no manejo de pragas. Nos últimos 20 anos, fatores econômicos, ambientais e técnicos têm caminhado juntos para gerar um pequeno, mas crescente, número de ecologistas químicos trabalhando na química e biologia dos feromônios na América do Sul. Neste artigo, foram compilados os resultados desta tendência. Foram revisados os estudos feitos com feromônios nos quais os cientistas da América do Sul têm participado em parceria com cientistas estrangeiros, majoritariamente grupos de química, como também os estudos realizados dentro da região. O principal objetivo são as pesquisas que envolvem a caracterização dos feromônios de espécies nativas, as quais compreendem as ordens mais importantes como Lepidoptera, Coleoptera, Heteroptera e Himenoptera. É também apresentada uma meta-análise, incluindo a distribuição geográfica, a tendência dos trabalhos de colaboração ou independente, e a evolução nos últimos 20 anos dos artigos publicados na área. Finalmente, é enfatizada a importância do esforço coordenado para promover o avanço deste campo na América Latina, através do respaldo e colaboração internacional dentro da região. Esta meta deverá ser alcançada através de uma organização acadêmica regional, incumbida da realização contínua de encontros científicos.Insect pheromone research has a long and rich history built up primarily by studies conducted in the Northern hemisphere. Not surprisingly, these studies have largely targeted species relevant to these regions of the world, for the most part agricultural and forest pests. Pheromone research in South American countries came a few decades behind, albeit their strong dependence in agriculture and therefore in pest management. In the last 20 years, a combination of economic, environmental and technical factors have come together to generate a small but rising number of chemical ecologists working in pheromone chemistry and biology in South America. In this article we summarize the results of this trend. We review pheromone studies in which South American scientists have participated in collaboration with foreign scientists, mostly chemistry groups, as well as the ever-growing number of studies carried out completely within the region. We have focused mainly in research involving the characterization of pheromones from native species, which involve the most important insect orders, namely Lepidoptera, Coleoptera, Heteroptera and Hymenoptera. We also present a simple meta-analysis including geographical distribution, trends in collaborative or independent work, and a 20-year evolution of published articles in the field. Fin...
