Abstract
Laboratory study was preformed to demonstrate the effectiveness of seven commercial insecticides from different manufactures and widespread in local markets on larvae and pupae of
Culex sp .
Four larval instars and pupae of the mosquito’s Culex sp. were chosen and collected from several ponds in Aljubaila and Garmat- Ali regions for applying this experiment. The larvae were exposed to three concentrations for each insecticide 250 , 500 , 1000 ppm ,the LT50 was calculated for each concentration of each insecticide , results showed that ElAskari insecticide is outdo another insecticides in killing by LT50 (7.49 , 12.88 , 19.63 ) for three concentrations respectively , and the insecticide with lower effectiveness was Flit Sole by LT50 ( 14.15 , 25.31 , 35.53 ) for three concentrations respectively.
