A model for the repellent effect of pyrethroid insecticides on insects was developed. Experiments were conducted using a small colony of honey bees in a flight cage. Conditioning to scented feeders allowed the separation of foraging bees from a single colony into treatment and control groups. Permethrin, cypermethrin, fenvalerate and flucythrinate were shown to be contact repellents to honey bees; exposure was primarily to the tarsi and ventral abdomen. The threshold dose of permethrin required to induce repellency was ca. 3.8 ng/bee. Repellency was fully reversible within 24 hours. No permanent effects on either memory or foraging efficiency were observed following acute exposure.
