Estudos bionômicos de Triatoma pseudomaculata Corrêa e Espínola, 1964 em condições de laboratório (Hemiptera: Reduviidae, Triatominae)

Abstract

The triatominae insects are hemimetábolos and vampire required at all stages of their life cycle, hematophagism being vital for the existence of the molting process/moulting. Under laboratory conditions it was observed that the life cycle of the insects varies temperature eccoding to the blood meal. This present study aimed to analyze bionomic parameters on longevity, intermoulting period, pre fasting and post-molt, offered blood meal and paid meal in all stages of development. The experiment was conducted from July 2002 to October 2003, under ambient conditions. Separated were 50 nymphs that hatched on the same date 07.21.2002. The period of development corresponding from hatching until adult hood was approximately 176 days. Of the 50 individuals analyzed, only 41 reached adult hood. The different aspects of the behavior of the insects have been studied by several authors, especially those species that are actively involved in the transmission of Chagas disease.
