Technical Abstract: New mosquito management strategies that reduce reliance on chemical insecticides by utilizing combinations of attractants and traps have been developed. This presentation will focus on laboratory and field evaluation techniques used to determine the efficacy of these combinations. Volatile chemicals, primarily those which emanated from human skin, were initially evaluated in a triple cage, dual port olfactometer to assess the attractio of 6-8 day old laboratory reared nulliparous female Aedes aegypti. Over 125 chemicals have been screened for activity. Many of these compounds produce attraction at high chemical emission rates. Blends of multiple compounds have been developed that provide collection efficiencies, measured by percent attraction, equal to or greater than that of the human hand. Some of these blends have also been evaluated against laboratory reared mosquitoes in a large outdoor screened cage and against natural populations by means of Counter Flow Geometry traps. Data will be presented that show the importance of species-specific attractant blends, trap type, and trap spacing in obtaining meaningful population reduction. The future prospects of removal trapping for control of nuisance and vector reduction. The future prospects of removal trapping for control of nuisance and vector mosquito species will also be discussed.
