The Present paper may help to know about some groups of pests associated with stored products and the seasonal variation of pests. In our study three stations were selected such as site-1 House, site-2 Supermarket and site-3 Ration shop in Malappuram district, Kerala. A total of eight species from 10 different samples of stored products were investigated. The eight different species which were collected from the three different areas come under two different insect orders namely Coleoptera and Lepidoptera. The percentage of species occurrence from three different sites revealed that Tribolium castaneum (Red flour beetle) was the most dominant pest which constituted 18.46% of the total insect pest population in the three sites.
