Comparative Laboratory study of fungi Beauveria bassiana and Maxforce bait against germen cockroach Blattella germanica

Abstract

The entomopathogenic fungus Beauveria bassiana is the most important in biological control for many insects .In this study we used spores extract of entomopathogenic fungus to control German cockroach Blattella germanica with three concentrations (4.1x10 4 , 4.1x10 6 , 4.1x10 8 spore \ ml) and comparative with maxforce bait under laboratory condition (25 ± 2°C and 70 ± 10% RH). Both nymphs and adults are tested to detect the effect of pathogenic and bait. the results showed significant differences P<0.05 between the different concentrations comparing with control while the nymphs were more sensitive than adults. The study showed significant differences between entomopathogenic fungus and bait .
