INTRODUCTION

Propoxur is a non-systemic insecticide which was introduced in 1959 . Propoxur is not used on food crops. It is used against mosquitoes in outdoor areas, for flies in agricultural settings, for fleas and ticks on pets, as an acaricide, on lawns and turf for ants, on flowering plants, and in private dwellings and public buildings. It is also used as a molluscicide, a chemical that kills snails. It is effective against cockroaches, aphids and leafhoppers . Propoxur is one of the chemicals that have, to a large extent, replaced DDT in the control of black flies and mosquitoes . It is a nonsystemic insecticide with contact and stomach action that has longstanding residual poisonous, or toxic activity when it is in direct contact with the target pest . Many formulations are available including ready-to-use liquids and aerosols, emulsifiable concentrates, wettable powders, granular baits, dusts and impregnated pet collars and strips .

Propoxur is one of a family of insecticides called carbamates. These chemicals block the production and action of cholinesterase, an essential nervous system enzyme. These materials quickly paralyze the nervous systems of insects, gaining them a reputation of having a rapid "knockdown" effect . Please refer to the Toxicology Information Brief on cholinesterase-inhibition for a more detailed discussion of cholinesterase inhibition.
