Decline of Anopheles sergentii and Aedes caspius populations following presentation of attractive toxic (spinosad) sugar bait stations in an oasis.
The effect of attractive sugar bait stations, including sucrose, juice of nectarine, slow-release substances, preservatives, red food-dye marker, and the oral insecticide spinosad, on Anopheles sergentii and Aedes caspius populations was studied in a small oasis in a southern desert of Israel. Feeding on similar baits without an insecticide was monitored as a control in a similar neighboring oasis. The insecticide caused a drastic decrease in the number of mosquitoes. Compared to the control site, the An. sergentii population was reduced to less than a tenth and that of Ae. caspius declined to a third. The majority of the mosquitoes, 76.0% of An. sergentii females and 74.8% of Ae. caspius females, were marked by the food dye in the control site.
