Association Of Esterases In Resistance To Naled And Resmethrin In The Southern House Mosquito, Culex Quinquefasciatus, Jennifer R. Gordon

LSU Master's Theses

The vector-competency and its affinity for humans make C. quinquefasciatus an important target of mosquito abatement programs. Whenever such control programs are implemented, protocols to monitor frequencies and mechanisms of resistance to the insecticides used are necessary to optimize the efficacy of the management strategy and to slow development of resistance to the insecticides used. In the current study, susceptibilities to the two adulticides used by EBRMARC (naled and resmethrin) were monitored using field-collected mosquitoes and a topical and contact bioassay, respectively. My hypothesis was that esterase-mediated enhanced metabolism conferred resistance to both insecticides in populations of C. quinquefasciatus from …
