Abstract
The Cowpea aphid, Aphis craccivora Kock, is a common pest of several important ornamental plants.This work aims to investigate the toxic effect ofBacillus thuringiensis and Beauveria bassiana isolate on 2-3 days old adult A. craccivora,the effect of the bioinsecticide was strong on adult individuals. On the other hand the calculated LC50 values on newly emerged adults of aphid were 6.31 CFU/ml and 73868X106 spores/ml, respectively. This study has shown that, the fungus has a more effective than bacteria on adult aphids.
