PROBLEM TO BE SOLVED: To provide a microorganism comprising microbial cell, spore or sporangium exhibiting excellent controlling activity against insects of the family Scarabaeidae including cupreous chafer and oriental beetle, provide a method and an agent for controlling the insects of the family Scarabaeidae using the microorganism and provide a controlling agent exhibiting similar insecticidal effect independent of the species on the insects of the family Scarabaeidae, especially representative and serious harmful insects comprising cupreous chafer, oriental beetle, soy bean beetle and Japanese beetle and applicable over a wide application period. SOLUTION: The microorganism is Bacillus popilliae var. popilliae DIC-2001 (FERM P-18250) exhibiting insecticidal activity against oriental beetle and cupreous chafer and strong insecticidal action against oriental beetle. The method for controlling the insects of the family Scarabaeidae comprises the application of the microorganism to the insect. The invention further provides a controlling agent for the insects of the family Scarabaeidae containing the sporangium of the above microorganism.
