Abstract
Human-skin-surface lipids have been shown to he repellent to the yellow-fever mosquito, Aedes aegypti (L.). The hydrocarbon portion of these lipids is responsible in part for the repellency. Fractionation of the hydrocarbons from skin lipids was accomplished by chromatographic techniques and the various fractions were evaluated for repellency in a dual-port olfactometer. The repellency of the hydrocarbon fraction was found to be solely in the unsaturated portion. Of several pure terminally unsaturated hydrocarbons tested, only eicosene was significantly repellent to the mosquitoes.Keywords
