MEASURING MOSQUITO REPELLENCY

Abstract

A machine is described which generates a standard, mosquito-attracting “target” to which controlled additions of various volatile chemicals can be made and the amount needed to repel the insects thereby measured in micromoles per liter of air. The apparatus can be used with both solids and liquids as well as with blends or mixtures. While principally intended for testing mosquito repellents, it can probably be adapted for use with other biting insects and ticks.
