“…40% for T. infestans. Stridulation in triatomines has been considered by several authors, either as a sexually related behaviour or as a defense response (Moore 1961, Manrique & Lazzari 1994, Roces & Manrique 1996, Manrique & Schilman 2000, Schilman et al 2001). According to Manrique and Lazzari (1994), non-receptive T. infestans females stridulate spontaneously, in order to reject the male copulatory attempts.…”

“…According to Manrique and Lazzari (1994), non-receptive T. infestans females stridulate spontaneously, in order to reject the male copulatory attempts. Roces and Manrique (1996) and Manrique and Schilman (2000) studying the stridulation of T. infestans and R. prolixus respectively, suggested that the relevant signal is a substrate borne vibration. In addition, they found differences in the frequency and temporal pattern of the signals produced by the same individual in different contexts, i.e., rejecting a male or after mechanical disturbance.…”

“…Schilman et al (2001) make the fascinating suggestion that the apparently species-nonspecific stridulations of triatomines function as a kind of auditory aposematicism, warning possible predators that the bugs with their isobutyric acid are distasteful. This view of triatomine stridulation is indirectly supported by the fact that in Triatoma infestans (Klug) (Roces & Manrique 1996) (Fig. 2) and in Rhodnius prolixus Stål (Manrique & Schilman 2000), both sexes produce disturbance stridulations, and unreceptive females produce a different stridulation to repel unwanted male attention.…”

Triatominae (Hemiptera: Reduviidae): Questões Sistemáticas e Algumas Outras RESUMO -Os vetores da doença de Chagas são classificados como membros dos reduviídeos da subfamília Triatominae. Entretanto, essa classificação tem sido referida como incorreta por alguns autores, que consideram que alguns (ou todos?) os grupos de Triatominae têm diferentes ancestrais não-triatomíneos. Neste artigo essa questão é discutida amplamente e outras questões relacionadas ao tema são também levantadas, em particular a posição sistemática de Linshcosteus, o único gênero de Triatominae que ocorre fora do Novo Mundo (na Índia). Outro exemplo é o fato de diversas espécies e populações terem derivado da espécie tropical Triatoma rubrofasciata (De Geer). A resposta a essas questões -se os triatomíneos têm mais de um ancestral não-triatomíneo e, portanto, seriam filogeneticamente distantes -não tem apenas interesse acadêmico. É impossível generalizar para todos os grupos o que é conhecido apenas para um grupo, e isso pode prevenir o controle desses vetores de doenças. Portanto, é literalmente vital determinar se Triatominae é um grupo holofilético e, se não, quais grupos classificados como triatomíneos são relacionados entre si. Essa determinação poderá ser feita através da análise cladística dos generos atualmente incluídos em Triatominae. Alguns comentários sobre cladística são apresentados em um Apêndice. PALAVRAS-CHAVE: Doença de Chagas, Trypanosoma cruzi, Rhodnius, Linshcosteus, cladística ABSTRACT -The Neotropical Chagas' disease vectors are classified as members of the reduviid subfamily Triatominae. However, this classification has been suggested to be incorrect, and the suggestion has been treated as fact by some authors; the suggestion is that some (all?) groups in Triatominae had different nontriatomine reduviid ancestors. In this article I raise this question explicitly and ask other questions ancillary to it. I do not answer these questions. Of particular interest is the systematic position of Linshcosteus, the only genus of Triatominae all of whose species occur outside the New World (in India). Related to this question is that of the origin(s) of the several species and populations probably derived from the tropicopolitan Triatoma rubrofasciata (De Geer). Answering these questions is of more than academic interest, for if triatomines had more than one nontriatomine ancestor, and therefore are not phylogenetically close, it is impossible to generalize what is known about one group to others, and this inability may hinder control of these disease vectors. It is therefore vital (literally!) to determine if Triatominae is a holophyletic group and, if not, to determine which groups now classified as triatomines are related to which others. This determination may best be accomplished with a cladistic analysis of the genera now included in Triatominae. Some comments on cladistics are presented in an Appendix.

“…The term male-deterring stridulation has been used to describe this behaviour by nonreceptive females. This behaviour has been reported as source of a substrate-borne signal which plays a role in intraspecific communication in T. infestans and R. prolixus [13,14].…”

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.
