Susceptibility Of The Southern House Mosquito, Culex Quinquefasciatus, In East Baton Rouge Parish To Larval Insecticides, Nicholas Alexander Delisi

LSU Master's Theses

Mosquito control districts in Louisiana focus their efforts on Culex quinquefasciatus, the primary vector of West Nile virus in the southern United States, with rigorous larvicide treatments. However, the development of resistant populations of Cx. quinquefasciatus in response to extensive insecticide application has been demonstrated repeatedly. Examining changes in insecticide susceptibility and larvicide efficacy in real world scenarios can help inform mosquito control districts as to whether or not their treatments are killing mosquitoes. We hypothesized that frequent larvicide applications for the control of mosquitoes in East Baton Rouge Parish had lowered susceptibility of wild Cx. quinquefasciatus to insecticides, and …
