ABSTRACT
Chagas disease is one of the most important vector-borne diseases in Latin America. Studying the biological parameters of each vector species or subspecies contributes to our understanding of their epidemiologic importance. The aim of our study was to compare the biological parameters and start to estimate the vectorial capacity of Triatoma protracta protracta Ryckman, T. p. nahuatlae Ryckman, and their laboratory hybrids. Specifically, we estimated nine biological parameters to increase knowledge about the potential role of triatomine hybrids in the transmission of T. cruzi to reservoir hosts. Nine biological parameters related to the lifecycle, feeding and defecation patterns, number of females, fecundity, and egg eclosion rates in cohorts of T. p. protracta, T. p. nahuatlae, and their hybrids were evaluated and compared. Eight parameters (exception number of laid eggs) indicated that T. p. nahuatlae was a potentially effective vector of T. cruzi. Our results showed that the hybrid cohorts had better fitness and could potentially have higher vectorial capacity than the parental cohorts. The outstanding characteristics of the hybrids found in our study could lead to an increase in the epidemiologic risks caused by transmission of T. cruzi to humans.
