Pyriproxyfen as a Mosquito Larvicide

Abstract:
Pyriproxyfen is an insect growth regulator that affects the physiology of morphogenesis, reproduction and embryogenesis of insects. It exhibits a high level of activity against mosquito larvae inhibiting adult emergence at very low dose rates. It has low mammalian toxicity and environmental impact. This paper reviews pyriproxyfen efficacy against nuisance mosquitoes and vectors of dengue and malaria. Pyriproxyfen is useful in resistance prevention or management strategies where chemical adulticides are being used since field resistance is unknown. Pyriproxyfen can be transferred by adults to oviposition sites causing effects on egg eclosion and inhibition of emergence.
