The warehouse pest data obtained will be grouped based on water content, varieties and pests obtained in 1 table. Next, the number of warehouse pest populations is calculated, the population average is calculated, the damage intensity is calculated, the data is tabulated and analyzed descriptively. The observation results showed that the Bisi 2 variety had the highest population of warehouse pests and the intensity of damage with a population of 143 Doloessa viridis, Tribolium sp. 58 individuals, 242 larvae and 11 pupae, with the highest average damage intensity reaching 34.6%. Meanwhile, the warehouse pest population and intensity were the lowest in the RK 457 variety with a total population of Tribolium sp. 8 tails with damage intensity reaching 8%.
