Development of Wuchereria Bancrofti in culex pipiens L. [Diptera: Culicidae] exposed in the larval instar to sublethal dosages of insecticides and one insect growth regulator and their influence on reproduction of filaria-infected mosquitoes

The effects of exposure of Culex pipiens larvae to sublethal concentrations of larvicides on uptake and development of Wuchereria bancrofti, survival rate and reproduction of filaria- infected mosquitos were investigated. The overall infection and infective rates were significantly reduced in mosquitos treated with Triton X-100, either alone or combined with permethrin. All larvicides reduced the number of infective larvae [L3]/mosquito and induced deformities among the different parasite stages. Addition of Triton X-100 to DPX or to permethrin significantly reduced egg Production
