Abstract
The domestic mosquito Culex pipiens (Diptera: Culicidae) is one of the most
important public health pests spread in Egypt. So the aim of this research was to
study toxicological effect of some organic and bio-pesticides on adult instar of the
domestic mosquito that collected from different location of Cairo Governorate in
Egypt, during the period of 2020-2022 in Toxicology Enviromental Research
Unit, Faculty of Agriculture, Ain Shams University. We use three organic
Insecticides (Chlorpyrifos, Lambda-cyhalothrin , Imidaclopride) and two bioInsecticide (Emamectin benzoate, Spinosad) at different concentrations (0.01, 0.1
and 1ppm) were applied on mosquito adult. It was recorded the value of LC50,
toxicity and the resistance rate to different pesticides on the field and Susceptible
strains after 24 hours of treatment. The result showed the highest effect on the
East strain then the North strain to Chlorpyrifos. In the case of the Lambda -
cyhalothrin had the highest resistance in the South strain. In Imidacloprid was the
resistance rate high in the South strain, and Emanating benzoate has higher in the
resistance in the East strain, while, Spinosad recorded higher resistance in the
South strain compared to The Susceptible strain. The relative Potency of
Spinosad was higher in all strains on adult of culex pipiens. Spinosad was higher
in toxicity index to the adult mosquitoes compared to other pesticides.
