Abstract

Abstract The pyrethroid insecticide, 3-phenoxybenzyl 3-( beta , beta -dichlorovinyl)-2,2-dimethylcyclopropanecarboxylate, is a potent repellent for a variety of insect pests, including acarids. This pyrethroid provides long-lasting protection when incorporated as the active component in repellent compositions and applied to areas from which it is desired to exclude such insect pests. The repellency extends to a broad range of species, including cockroaches, true bugs, flies, mites, aphids, and beetles, as well as mature and immature moths and butterflies.
