Impact of multi-generational laboratory rearing on the development and viability of Cochliomyia hominivorax.

ABSTRACT: The screwworm fly, Cochliomyia hominivorax, is a significant pest in Brazil, posing threats to agriculture and public health. Laboratory rearing is crucial for developing control strategies like the sterile insect technique (SIT); but the effects of multi-generational rearing on the fly's biological parameters are not fully understood. This study investigated the impact of rearing C. hominivorax for 12 inbred generations on its morphometrics, reproductive capacity, and life expectancy. Specimens were collected at distinct developmental stages across 12 generations for morphometric analysis, and key viability traits were assessed through biological assays. Data were analyzed using linear mixed-effects models and Kaplan-Meier survival analysis. The results revealed that morphometric paramete
