Abstract: The effect of 5 cultivated host plants (cotton, corn, bean, peanut and sesame) on the development and reproduction of cotton bollworm Helicoverpa armigerawere studied under constant temperature (27±1℃)and relative humidity(70%±5%).The results showed that there were significant differences of the development duration, pupa weight, survival rate, fecundity and longevity of adults among the cotton bollworms feeding on different host plants.The densities of cotton bollworm in corn, bean and other crops were higher, and the larvae development on different crops were irregular when investigated in the field, consequently.It was one of the reasons for generation confusion, control difficulty and severe demage of cotton bollworm that many crops coexisted in the fields.

Key words: Cotton bollworm, Host plants, Development, Population dynamics
