The aim of this research was to evaluate the biological behaviour of melonworm at different natural and artificial diets. Squash cultivar jacaré, cucumber, summer squash and an artificial diets developed by Hensley & Hammond for the sugarcane borer were tried. The research was carried out in the Laboratório de Entomologia do Centro de Ciências Agrárias of the Universidade Federal do Espírito Santo, in climatized room at 25 ± 1°C, relative humidity of 70 ± 10% and 14h photofase. The caterpillars fed on each substrate during the whole life cycle. Differences in duration of the larval period, larvae and pupae survival, adult longevity and number of eggs were registered between the substrates. The results show that the best diet for rearing is the artificial one. Between the natural diets the cucumber showed the best results.
