Study the morphological charactertics and the effect of foods on development and growth of Ostrinia furnacalis (Guenee, 1854) (Lepidoptera: Pyralidae)

The effects of foods on the life cycle, survival rate, and reproductive ability of Ostrinia furnacalis (Guenee, 1854) were studied in laboratory. Maize HN88-Fed O. furnacalis had a complete life cycle of 32.9 ± 1.7 days, which was 38.4 ± 1.5 days shorter than those fed with maize LVN4. The average survival rates of O. furnacalis on two types of feeds were 97.5% and 94.4%, respectively. When O. furnacalis were fed with 100% honey or 50% sugar or water, the average length of female life cycle as well as their everage laid egg number were 11.1 ± 0.9 days and 535.2 ± 77.2 eggs/female; 9.9 ± 0.8 days and 371.7 ± 47.4 eggs/female; 7.3 ± 0.6 days and 216 ± 32.6 eggs/female, respectively.
