to detect insects in rice, that correlated linearly with Isotropic Masks sized 7x7 [6], recognize stored-grain insects by analyzing texture of the insects with Hidden Markov model (HMM), which develope from K-mean method and the study of Insect behavioral studies; parasitoid species, especially insects especially the larva which is elastomeric in nature, which are used for biological control programs. Therefore, the estimated number of insects to be able to calculate and predict the spread of insects for warning farmers to prevent and eliminate pests. Including to estimated loss of productivity, if not wasted, insecticides. In this research, the image processing technique to detect brown planthopper, that is an insect pest of rice
