Cricula trifenestrata Helfer (Lepidoptera;Saturniidae) are insect pest of avocado, walnuts, and cashews. C. trifenestrata is most destructive insect pest of cashews, but there is no serious control by farmers. The questions about the effect of C. trifenestrata to cashew’s yield. This study aimed to determine the correlation and regression attack degree of C. trifenestrata to the number of flowers and seeds produced by cashew. Research was conducted by a survey of 30 cashew plants with 6 samples unit at each plant. The parameters observed in this study were plant varieties, plant age, time appears caterpillar, caterpillar number, the attack rate, days to flowering, the number of bunches, flower, and seed. The data were analysed by the correlation and regression analysis. The results showed a positive correlation between the degree of caterpillar attacks to number of flowers and seeds. Increasing degree of attacks may increase the number of flowers and seeds.
