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]

J Insect Sci, 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.

Combate ao Panstrongylus megistus com o Malathion concentrado [PDF]

Revista da Sociedade Brasileira de Medicina Tropical, 1975
O Malathion concentrado (0-0 dimetilfosforo ditioato de dietil mercapto - succinato) foi usado para combater o Panstrongylus megistus, principal vector da doença de Chagas, numa zona endêmica do Estado da Bahia. A eficácia do malathion no controle desse triatomíneo foi constatada após ter sido aplicado três vezes, no período de um ano e meio, em ...

Interpopulation Variability AmongPanstrongylus megistus(Hemiptera: Reduviidae) from Brazil [PDF]

Journal of Medical Entomology, 2003
Comparisons were made among Panstrongylus megistus (Burmeister) from three areas of Brazil (Bahia, Minas Gerais, and Santa Catarina), where populations differ with regard to their degree of association with human dwellings. The following characters were studied: morphology of the eggs and the male genitalia; morphometry of the head and thorax ...

Experimental evidence for a demographic cline in Panstrongylus megistus populations [PDF]

Memórias do Instituto Oswaldo Cruz, 2001
The population biology of three populations of Panstrongylus megistus was compared to determine possible influence on the behaviour and epidemiological importance of this species. The results demonstrated differences in terms of egg eclosion time, nymphal mortality and development rates, and feeding and defaecation rates.

Phylogenetic structure of geographical co‐occurrence among New World Triatominae species, vectors of Chagas disease

Journal of Biogeography, Volume 47, Issue 6, Page 1218-1231, June 2020., 2020
Abstract Aim The tropical niche conservatism (TNC) hypothesis is one of the most prominent evolutionary hypotheses that has been supported as an explanation for the diversity gradients of several animal taxa, mainly vertebrates. However, the validity of TNC for less‐known taxa such as disease vectors is not clear.
