“…Recently, Pontes and Lorenzo [47] have shown that the occlusion of R. prolixus female metasternal glands also prevented male aggregation around mating pairs, whereas the occlusion of male metasternal glands did not affect male aggregation. In addition, occlusion experiments also showed that Brindley's gland products are not required for normal mating and male aggregation [15]. In sum, these experiments suggest that volatile compounds from metasternal glands may be among the key signals used in mating interactions.…”

“…More recently, further compounds have been identified from two triatomine species, including the acetal (4S,5S)-2,2,4-triethyl-5-methyl-1,3-dioxolane and related compounds [37,48]. Occlusion of female metasternal gland orifices resulted in a significant decrease in copulation frequency and prevented the male aggregation behaviour described for this species, suggesting that metasternal gland odours mediate the sexual behaviour of T. infestans [15]. Because the attractiveness of mating pairs decreased after occluding female metasternal glands, it was suggested that females emit volatile compounds that promote both copulation and male aggregation behaviour.…”

“…It has been demonstrated that odours from the metasternal glands promote mating in T. infestans and R. prolixus [15,16]. In addition to the volatile compounds secreted by the metasternal glands, it has been suggested that epicuticular lipids may play a role as female recognition signals (i.e., contact pheromones) in T. Infestans, but this needs to be confirmed [17].…”

Chemical communication mechanisms that mediate sexual behaviour in triatomine bugs are reviewed with regard to source, identity, and function of sex pheromones. Males attempt to copulate but may be rejected, depending on female age and nutritional status. Triatomine males locate partners through sex pheromones emitted by the metasternal glands (MGs) of females. These activate males, inducing them to leave their refuges and initiate flight. Wandering males display anemotactic orientation modulated by chemical signals emitted from female MGs. Analyses of the MG secretions of several species resulted in the identification of numerous ketones, acetals, and alcohols. Occlusion experiments showed that Brindley's gland products were not required for mating. Metasternal gland volatiles are emitted by virgin male and female bugs, with detection over females occurring more consistently, especially during the early scotophase, suggesting female calling behaviour. Mating triatomine females have been reported to attract males that tend to copulate successively with them. Mating males prolong mating and postcopulatory mate guarding in the presence of other males. This is indicative of a polyandrous mating system in several triatomine species. Its potential advantages remain unknown, and comparative studies are required to increase our understanding of triatomine reproductive strategies.

“…89 Some of the compounds identified were electrophysiologically active and were also attractive to males and/or females. The role of Brindley's and metasternal glands in chemical communication of T. infestans has been studied 90 and it has been suggested that volatiles released from the metasternal glands are involved in sexual and alarm behavior of this species. 90,91 Several compounds have been identified from metasternal glands, including 3-pentanone, 2-methylbutanol, and 3-pentanol.…”

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...
