 en SHORT COMMUNICATION - Experimental Evidence for a Demographic Cline in Panstrongylus megistus Populations
Silvia E Barbosa; Rodrigo PP Soares; Herton HR Pires & Liléia Diotaiuti

Abstract

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. These differences appeared to follow a geographical cline, primarily reflecting different degrees of adaptation to domestic habitats.
