The ability of sterile males to survive, disperse, find, and mate with wild females is key to the success of sterile insect technique (SIT). The Release of Insects carrying a Dominant Lethal (RIDL) system is a genetics-based SIT strategy for Aedes aegypti. We examine two aspects of insect performance, flight potential (dispersal ability) and teneral energy reserves, by comparing wild-type (WT) males with genetically-modified lines carrying the tetracycline-repressible constructs OX513A and OX3604C.

Background

Yellow Fever virus (YFV) is an important arboviral pathogen in much of sub-Saharan Africa and the tropical Americas. It is the prototype member of the genus Flavivirus and is transmitted primarily by Aedes (Stegomyia) mosquitoes. The incidence of human infections in endemic areas has risen in recent years. Prompt and dependable identification of YFV is a critical component of response to suspect cases.
