title: Determination of toxicity of danitol, methoprene and neem formulation against stored grain pest, sitophilus oryzae L.
abstract: Toxicity of a synthetic pyrethroid (Danitol 10 E.C.), methoprene (J.H.A.) and crude neem extract formulation (RB-b +PBO +Tx) in synergestic form was determined in laboratory by contact method against adults of Sitophilus oryzae. Observations after 24 hours of treatment showed that 50% of the adults died at 0.39 mu/cm(2) of Danitol, 6.28 mug/cm(2) of neem formulation and 18.85 mug/cm(2) of methoprene, the three products used in this experiment. Danitol was found more effective as compared to neem formulation and methoprene. It was found that the plant product formulation and a synthetic product are more effective than methoprene.
