Abstract

West Nile virus (WNV) is the most widespread arthropod-borne viral disease in the United States and is transmitted primarily by Culex pipiens. Methoprene is a pesticide used to control mosquito populations. Evolution of resistance threatens the longevity of any given insecticide with continued use. The objective of this research is to examine any fitness costs associated with resistance to methoprene in Cx. pipiens. Fitness will be examined by measuring wing length in laboratory-reared methoprene resistant and susceptible colonies of Cx. pipiens. Wing length serves as a proxy for body size. It is hypothesized that methoprene resistance in Cx. pipiens mosquito populations will result in fitness costs, such as reduced wing size.
