Beauveria bassiana as an entomopathogenic fungi showed high effects on the aphid Aphis crassivora and the white fly Bemesia tabaci infesting cucumber. A dose of 1 mg.ml −1 killed 100% of either insects. Lower doses showed lower effects. Nymphs of the two insects were markedly affected by treatment of the fungi. The total duration and the number of survivors were significantly decreased by an increase in the dose of the pathogen. Latent effects were clearly observed in the resulting adults. Adult longevity, period of reproduction and fecundity were markedly decreased by an increase of B. bassiana dose. The increase in dose of the pathogen increased the resultant winged form of A. crassivora up to 91.7% at 0.5% mg.mr −1 .
