In: Assiut Journal of Agricultural Sciences 2009.v.40(2)Summary: Toxicity of six compounds representing, carbamate (methomyl), tow organophosphates (chlorpyrifos and temephos), pyrethroid (a-cypermethrin), chitin synthesis inhibitor (chlorfluazuron) and bioinsecticide (abamectin) was evaluated against 2nd and 4th instar larvae,and pupal stage of Culex pipiens under laboratory conditions. The pyrethroid, a-cypermethrin showed the highest toxic effect against 2nd and 4th instar larvae, and pupal stage too. Temephos was the least toxic compound against the 2nd instar larvae and pupal stage, while abamectin was the least toxic one against the 4th instar larvae.
