The present paper discusses the survival, reproduction, development, harmfulness, and F2 reproduction potential of the Indian meal moth (Plodia interpunctella Hbn.) on dried fruits. The Indian meal moth (IMM) is a species that can develop on the surface of dried fruit. The IMM was grown on three different kinds of store-bought dried fruit. On average, the females laid a relatively high number of eggs per pair: 45.36 in raisins, 41.52 in dried apricots, 13.94 in prunes. However, the mortality of the eggs and caterpillars was high, ranging from 94.4% in dried apricots to 98.7% in raisins and prunes. The highest number of offspring was obtained in dried apricots (1.5/pair), followed by raisins (0.7/pair), and prunes (0.2/pair). The F1 population size was small, the moths had a short lifespan, the males outnumbered the females, and the eclosion of females did not coincide with that of males. As a result, the number of offspings in the F2 generation was negligible. The results of the present study notwithstanding, the fact remains that the IMM adapts very easily to different media and can be a major pest on a wide variety of stored products, including dried fruits. The IMM causes the most damage by altering the appearance of dried fruits, as the presence of caterpillars, exuviae, bite marks, feces, and silken threads reduces the market value of the product.
