Technical Abstract: A spatial repellent is a chemical compound that in the vapor phase can produce repellency at a distance, significantly reducing the number of target species in a defined area over a designated period of time. Several compound classes have been reported to produce spatial repellency of Aedes aegypti, including essential oils, such as citronellal and geraniol, pyrethrums and synthetic pyrethroids. Several commercial products have been produced utilizing these compounds. Although many of these commercial products appear to show promise, they have not been adequately evaluated in peer-reviewed studies. The studies reported in this presentation were conducted in attempt to help fill that knowledge gap. Protocols were developed to evaluate these commercial products and other candidate compounds in laboratory olfactometer, semi-field and field studies against laboratory reared and/or natural populations of mosquitoes. It was determined that these compounds have both mortality and repellency properties. Olfactometer studies emphasized screening candidate essential oil compounds; semi-field and field studies emphasized evaluations of an increasing array of commercial products, which contain active ingredients such as metofluthrin and allethrin.
