| Abstract | ||
| A study was conducted to evaluate the pathogenicity of entomopathogenic: fungi Beauveria bassiana (sixe isolates), Verticillium lecanii: fungi Fusarium solani, Penicillium sp., Aspergillus sp. and Paecillomyces sp as biocontrol agents for controlling Blattela germanica under laboratory condition. Results indicated that all entomopathogenic fungi appeared to be a good biocontrol agents its efficacy varied according to the fungi species and insect stage while early instars more effective late instars .Isolate Bb1, Bb3, Bb4 and Bb6 showed the highest percentage of parasitism (100%) on different instars after 8 days, compared with other treatments under controling condition .Toxic baits of isolates Bb1, Bb3, Bb4 and Bb6 induced highest percentage of mortality after 15 days of application under non controlling condition. | ||
