“…29,[40][41][42] It was previously demonstrated that P. megistus and T. infestans show cross-aggregation responses to chemical signals from feces and cuticle of the other species. 29 In other taxa of Hemiptera, intra-specific and inter-specific aggregation responses were also demonstrated.…”

Abstract. Triatoma infestans and Panstrongylus megistus are relevant Chagas disease vectors. An apparent segregation among these triatomine species inside human households was suggested to rely on mutual repellence between them. However, P. megistus and T. infestans show aggregation responses to chemical signals emitted by the other species. These findings do not rule out the possibility that stimuli other than chemical signals could mediate repellence when these species exploit shelters simultaneously. In the present study, we investigated how P. megistus and T. infestans exploit shelters in controlled laboratory conditions and how insect density and environmental illumination modulate this behavior. We evaluated whether these species aggregate inside shelters or mutually repel each other. Panstrongylus megistus and T. infestans show specific patterns of shelter exploitation, which are differentially affected by insect density and environment illumination. In particular, P. megistus is more sensitive to insect density than T. infestans, whereas T. infestans shows higher sensitivity to illumination than P. megistus. Nevertheless, these species exploit shelters randomly without any apparent repellence.

“…Chemical communication is involved in many aspects of their lives and pheromones promoting assembling, mating and alarm behaviours have been partially characterised (Baldwin et al 1971, Schofield & Patterson 1977, Lorenzo Figueiras et al 1994, Manrique & Lazzari 1995, Lorenzo Figueiras & Lazzari 1998a, b, Cruz-López et al 2001, Vitta et al 2002, Pontes et al 2008. Vibrational communication associated with stridulation has been described in male-female interactions related to a female's rejection of copulation attempts by males.…”

“…These instances are related to mating, alarm, assembling and substratemarking behaviours. Among them, the aggregation signals present in triatomine faeces appear to be the most promising for triatomine control for several reasons: (i) faeces samples can be easily obtained from rearing facilities, since the paper or cardboard sheets usually used as substrates are a rich source for triatomine waste; (ii) modern chemical methods should be able to unravel the composition of these pheromones and eventually produce synthetic versions of them; (iii) the pheromones remain effective for almost two weeks ; (iv) the way triatomines convey information using the pheromones found in faeces is understood (Lorenzo & Lazzari 1996); (v) pheromones in faeces are able to attract and assemble triatomines in an unspecific fashion (Lorenzo Figueiras & Lazzari 1998a, Pires et al 2002, Vitta et al 2007); (vi) pheromones in faeces are used in the context of finding shelters (Lorenzo & Lazzari 1996).…”

“…An aggregation behavior has been described for T. infestans and several other reduviid species, which are also vectors for T. cruzi. Larvae of T. infestans, 81,82 T. pseudomaculata, 83 T. sordida, 82 T. guasayana, 82 Rhodnius prolixus, 84 and Panstrongylus megistus 85 are attracted to their faeces. This attraction is not specific, as inter-specific attraction to excrements has been shown for several species.…”

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...
