Abstract
The Cowpea aphid, Aphis craccivora Kock, is a common pest of several important plants. The toxic effects of different concentrations of the fungus Beauveria bassiana spores, and different concentrations of the leaf extract of Nerium oleander against Aphis craccivora Kock adults was calculated. The obtained results showed that the highest mortality percentages of aphid adult stages was 60 % recorded at the treatment of B. bassiana (1x107spores/ml) , while it was 91 % for the treatment of Nerium oleander leaf extract (2000 ppm). The lowest reduction percentages of aphids were recorded at the treatments of B. bassiana at the rate of (1x103 spores/ml) and the treatment
