Emergency mosquito aerial spray response to the 2004 Florida hurricanes Charley, Frances, Ivan, and Jeanne: an overview of control results

Abstract

In total, 43 aerial spray missions were conducted in 26 Florida counties to control mosquito populations after each of the 4 hurricanes making landfall in Florida in 2004. Mosquitoes were trapped before and after each spray mission to determine the percentage (%) of control for the West Nile virus vector Culex nigripalpus (64.1%), the floodwater pest mosquito Psorophora columbiae (69.7%), and for all species combined (67.7%). A discussion on these results and suggestions for future efforts are presented.
