Tralomethrin (OMS-3048), a new synthetic pyrethroid against vector mosquitoes

Tralomethrin (OMS-3048) a synthetic pyrethroid, was tested for its insecticidal properties in the laboraroey against normal strains of Culex quinquefasciatus, Cx. tritaeniorhynchus, Cx. sitiens, Anopheles stephensi, An. culicifacies, Aedes aegypti and Armigeres subalbatus and against strains of Cx. quinquefasciatus resistant to fenthion and malathion. Tralomethrin showed good larvicidal activity against all the species tested. LC50 ranged between 7.00×10 #756 and 9.10×10 3 mg (ai)/l
