The disruption of chemical communication between adult insects by the use of synthetic sex pheromones is an attractive method of insect control. However the mechanism of disruption is not clearly understood. It is generally considered that 3 mechanisms are in operation (see review by Bartell 1982): masking of the natural-pheromone plumes by permeation of the atmosphere with synthetic pheromone; orientation of males to false trails; and habituation of the central nervous system by prolonged or repeated exposure to the pheromone. The relative importance of these 3 mechanisms in disruption is of concern, as this can affect the strategy for disseminating the pheromone.
