چکیده

This study was aimed to investigate the efficiency of some insecticides, (fenitrothion,cyphenothrin, azadirachtin and pyriproxyfen) against mosquito larvae of culex pipiens. data indicated the superior effectiveness of fenitrothion against larvae of culex pipiens followed by azadirachtin, cyphenothrin and pyriproxyfen. the lethal concentration values (lc50) were 4.1, 4.5, 8.4 and 60.0 ppm for fenitrothion, azadirachtin, cyphenothrin and pyriproxyfen,respectively. the relative potencies, based on pyriproxyfen, revealed the following values,14.6,13.3 and 7.1 fold for fenitrothion, azadirachtin and cyphenothrin, respectively
