The development of Panstrongylus herreri under fluctuating environmental conditions

Abstract

Introduction: Panstrongylus herreri is a main Chagas disease vector, and its success as a vector stems from its ability to establish domiciliated colonies; we aimed to explore its biology and reproduction. Methods: The average amount of blood ingested and the time from the beginning of a blood meal to the production of feces were recorded. Results: Females exhibited a higher blood ingestion rate than males, but similar defecation times and frequencies were observed. Conclusions: Despite the detected decrease in oviposition rates, P. herreri's potential as a Chagas disease vector in environments other than the Amazon forest cannot be discounted.

“…Se ha reportado que Panstrongylus herreri es un vector principal de la enfermedad de Chagas, y su éxito como vector se debía a su capacidad para establecer colonias domiciliadas, concluyéndose que, a pesar de haberse detectado una disminución en las tasas de oviposición, el potencial de P. herreri como vector de la enfermedad de Chagas en ambientes distintos del Amazonas debe ser considerado (18) .…”
