Desarrollo larval y requerimientos calóricos de Chrysomya rufifacies (Diptera: Calliphoridae) durante primavera y verano en Torreón, Coahuila

摘要: Diptera is one of the major groups insects that contribute to organic matter decomposition, including several species Calliphoridae and Chrysomya rufifacies (Macquart) has been recorded as principal colonizes carrion in Comarca Lagunera Coahuila.

Pregnant females collected, which reared obtained eggs biological until adult emergence. Five larvae specimens were measured every four hours, recording its length diameter instar changes. Temperature in the breeding room recorded calculate degree days accumulated (DDA) for this species. During spring 192.57 DD while it 190.69 DD, these amounts necessary from egg During summer C. pupated 96 hours after hatching. The results knowledge of biology increasing sarcosaprophagous fauna database Comarca Lagunera, especially Torreon,
