The Sexual Behaviour of Chagas′ Disease Vectors: Chemical Signals Mediating Communication between Male and Female Triatomine Bugs

Psyche: A Journal of Entomology, Volume 2012, Issue 1, 2012., 2012
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

Trypanosomes and gut microbiota interactions in triatomine bugs and tsetse flies: A vectorial perspective

Medical and Veterinary Entomology, Volume 38, Issue 3, Page 253-268, September 2024.
Trypanosoma sp. presence modulates or has zero effect on gut microbiota composition. Microbiota presence modulates or has zero effect on Trypanosoma sp. growth. Vector biology of triatomine bugs and tsetse flies influences their gut microbiota composition.

Hemoculture and Polymerase Chain Reaction Using Primers TCZ1/TCZ2 for the Diagnosis of Canine and Feline Trypanosomiasis

International Scholarly Research Notices, Volume 2012, Issue 1, 2012., 2012
Introduction. American trypanosomiasis, also known as Chagas disease, is a zoonosis caused by Trypanosoma cruzi (T. cruzi). Dogs and cats participate actively in this parasite′s transmission cycle. This study aimed at evaluating the occurrence of T. cruzi in dogs and cats from Botucatu, SP, Brazil, as well as at evaluating the technique of hemoculture ...

Ecological patterns of blood-feeding by kissing-bugs (Hemiptera: Reduviidae: Triatominae) [PDF]

, 2011
Host use by vectors is important in understanding the transmission of zoonotic diseases, which can affect humans, wildlife and domestic animals. Here, a synthesis of host exploitation patterns by kissing-bugs, vectors of Chagas disease, is presented. For

The fat body of the hematophagous insect, panstrongylus megistus (Hemiptera: Reduviidae): Histological features and participation of the β-chain of ATP synthase in the lipophorin-mediated lipid transfer [PDF]

, 2019
In insects, lipid transfer to the tissues is mediated by lipophorin, the major circulating lipoprotein, mainly through a nonendocytic pathway involving docking receptors. Currently, the role of such receptors in lipid metabolism remains poorly understood.

Triatomíneos: ação ovicida de alguns piretróides Triatomine: ovicida action of some pyretroids

Revista da Sociedade Brasileira de Medicina Tropical, 2002
A ação ovicida dos inseticidas tem sido pouco considerada nas atividades de controle dos transmissores da endemia chagásica. No sentido de comparar o potencial ovicida de três piretróides sintéticos (lambdacialotrina, alphacipermetrina e deltametrina ...

Nuclear rDNA ITS-2 sequences reveal polyphyly of Panstrongylus species (Hemiptera: Reduviidae: Triatominae), vectors of Trypanosoma cruzi.

, 2002
Panstrongylus species are widely distributed throughout the Americas, where they act as vectors of Trypanosoma cruzi, agent of Chagas disease. Their intraspecific relationships, taxonomic position and phylogeny in relation to other Triatomini were ...
