Technical Abstract: Prallethrin, one of the two active ingredients in DUET®, has previously been shown to activate Culex quinquefasciatus females in the laboratory resulting in greater mortality. In this study, formulations of DUET® prepared with and without prallethrin were evaluated in a wind tunnel with unfed and bloodfed Aedes aegypti and Ae. albopictus females. Formulations were delivered in a spray cloud of ULV droplets in a wind tunnel and the responses of individual mosquitoes were videotaped. Videotapes were analyzed using several behavioral analysis programs (e.g., Observer, Ethovision, Motus) and various parameters of flight (e.g., flight speed, duration, turning) were evaluated to determine the impact of the pesticide exposure. Comparisons of mortality at 8 hrs were made between the different formulations for each species. Results of this evaluation and their implications for field applications will be discussed.
