Evaluation efficiency of Metarhizium anisopliae fungi in larva mortality Culex pipiens

This study has targeted the evaluation of the efficiency metarhizium anisopliae fungi in different concentrations of bio control four stages Culex Pipiens mosquitoes. This study has been showed different results by different concentrations and exposure periods for all stages larva Culex Pipiens that was sensitive to selective concentrations 2x105,  2x107  and 2x109 spore/ml . The concentration 2x109 was recorded highest mortality in first stage reach (63.55), while lowest concentration While the rate of floating the same pours when concentration is 2x105 and reached (49.57) The rate of secondary and third, third and fourth phase has reached the top 2x109 (56.87, 48.55%, 44.80%), respectively, While the percharge rate itself is at least 2x105 (45.22%, 38.75%, 34.75%, 34.38%), respectively. With regard to exposure periods, the exposure period after (96) hours achieved a significant output at other exposure periods, where the rate of land phase The first (81.1%) is the rate of perhaps, while the exposure period (24) has given less rate for the same phase, amounting to 30.82%
