Laboratory bioassay of the fungus MfJlarhizium anisop < /em>liae included different stages oi two important cotton insects, Spodoplera littoralis(BoiSd) and Agrolis ipsilon(Huf.), under different concentrations of fungus. The fungus proved virulent against eggs and larvae of both insects. Treatment eggs of both insects pests reduced rate of hatchability. It was evident that eggs and larvae of both insects were susceptible to fungu! infection, and most of hatched larvae from treated eggs failed to devleop to adults and dead in both S.liltoralis and A.ipsi/on. LCso for S,/ittoralis eggs was 1.7 x 10~ spores/ml and 2.5 x 10~ sporeslml for larvae. LCso for A.ipsi/on eggs was 2.5 x 103 sporeslml, and 5.5 x 103 spores/ml for larvae. s.nnorsus appeared 10 be more susceptible than Aipsi/on through all the stages, and recorded more reduction in larvae, pupae, and adults during larval development of the newly emerging larvae from the treated eggs.
