In: Zagazig Journal of Agricultural Research 2003.v.30(3)Summary: Research studies were undertaken to investigate the possibility of using Verticillium Lecanii as a biological control agent for the control of Aphis craccivora. The Present work reported successful infection by V. Lecanii to the aphid Aphis craccivora. Pathogenicity test as well as the effect on some changes in certain biochemical components of treated nymphs were done. Results indicated that LC50 and LC90 were 0.85 x 107 and 2.7 x 107 spores/mL, respectively The tests proved reductions in total protein, fat, and- amylase enzyme.
