Laboratory experiments were conducted to evaluate the effect of some commercially available biopesticidal formulations, such as Bacillus thuringiensis var. kurstaki (2g/l), sphaericus(2g/l), Beauveria bassiana (5g/l), Metarhizium anisopliae Lecanicillium lecanii (5g/l) on Temperature Tolerant strain Trichogramma chilonis (TTT). Two sets conducted, in first experiment, all test biopesticides spr...

The 2362 strain of Bacillus sphaericus (Bs) Neide is a highly mosquitocidal bacterium used in commercial bacterial larvicides primarily to control mosquitoes of the genus Culex. Unfortunately, Bs is at high risk for selecting resistance in mosquito populations, because its binary toxin apparently only binds to a single receptor type on midgut microvilli. A potential key strategy for delaying re...
