Abstract: We conducted a truck ULV application in a community with Fyfanon ULV (a.i. malathion) in response to multiple WNV detections. To evaluate this application, we placed sentinel cages containing female Culex quinquefasciatus and spinners with Teflon slides in the treated area. Two sets of control sentinel cages and spinners were situated 0.25 miles and 0.75 miles away from the neighborhood being treated. The mosquitoes were knocked down in the control sentinel cages and the respective Teflon slides had droplets, suggesting that Fyfanon ULV drifted farther than we expected. This finding may affect how we define our mosquito treatment area and where to set our untreated controls.
