Abstract

The New World Screwworm fly, Cochliomyia hominivorax, is still one of the most damaging parasites of livestock in South America, provoking traumatic myiasis and losses of US$ 1.8 billion/year in Brazil. Before the beginning of new suppression/eradication campaigns, is required to confirm the inexistence of sexually incompatible populations and to characterize the genetic variation of the target population. For the past decades, some studies started to investigate the distribution patterns of genetic variation in C. hominivorax populations, but so far the wild populations of this plague from the Amazon basin were not studied, leaving unanswered questions about the influence of the Amazon rainforest in the gene flow of this species in the continent. This project aims to continue the investigation of the distribution of the genetic variation and structure of C.hominivorax populations from South America through collecting specimens in the Brazilian Amazon basin. The results will also serve to complete the phylogeographical history of this pest fly in the American continent.
