Cupreous chafer, <I>Anomala cuprea</I> HOPE is a major scarab beetle pest of turfgrasses, nurseries of forest trees and many field crops. The larvae of <I>A. cuprea</I> feed on the roots of grasses and plants in the soil, and they are very difficult to control. We assumed to control <I>A. cuprea</I> by using joint action between an entomogenous fungus <I>Metarhizinm anisopliae</I> and insecticides.<BR>Susceptibility of larvae of <I>A. cuprea</I> against <I>M. anisopliae</I> treated with stressors such as insecticides or entomogenous fungi were investigated. Fenthion and fenitrothion were effective to enhance susceptibility of 1 st instar of <I>A. cuprea</I> against <I>M. canisopliae.</I> period after treatment of <I>P, fumosoroseus</I> demonstrated no tendency for susceptibility of <I>A. cuprea</I> against <I>M. anisopliae. M. anisopliae</I> had the strongest pathogenisity against<I>A. cuprea</I>, after 12 hr treatment of fenthion. Stressors established with very low concentration didn't affect on the mortality of <I>A. cuprea</I> treated with <I>M. anisopliae</I>.<BR>These results showed that <I>M.anisopliae</I> treated with low concentration of organophosphates would become an effective control method against larvae of <I>A. cuprea</I>.
