Abstract

Four native isolates of entomopathogenic fungi Metarhizium anisopliae (M 01, M 02, M 06 and M 09) were isolated from Sinai Peninsula and evaluated against wheat aphid, Schizaphis graminum (Rondani). Four-concentrations of spores suspensions for every fungal-isolate 1×105, 1×106, 1×107 and 1×108 conidia/ml were used against adult aphid (one day old). The results showed that (M02) was the most effective according to LC50.
