Rice weevil belongs to COLEOPTERA, Elephantidae, also known as Mi Chong and Gu Niu. It is a completely abnormal insect, and its life experience is four development forms: egg → larva → pupa → adult. It is the main pest of stored grain, mainly parasitic in aged grain stored for 2~3 years, such as corn, rice, wheat, sorghum, flour and so on. Its adults eat grain particles, and its larvae eat the inside of grain.

Because of its rapid growth and reproduction, its geographical distribution can be spread all over the world, but it is mainly distributed in the south in China. In recent years, the harm of rice weevil has become more serious.
