Abstract: The LC50 of M. anisopliae var. frigidum 156X104 and 168 X104 spores/ml under laboratory and greenhouse effect, respectively. The corresponding LC50of M. flavoviride var. minus were 169 X104 and 172 X104spores/ml. The higest yied obtained in El-Esraa (Nobaryia) 3999 49.41 and 4697 49.33 Tons/kg in El-Kassaseen (Ismailia) after M. anisopliae var. frigidum treatments the yield loss ranged between 7 and 72 % in the two regions.
