Abstract: Results from experiments under controlled temperature showed that there exists a functional relationship between the development durations of egg, larvae and pupae of Agasicles hgrophila and the temperature.From 22 to 32℃,the development durations are obviously shortened with increasing temperature.The larval period has three instats and endures 8.8 days.The life span of adult is related to temperature and sex,and the females live longer than the males.The period of pre oviposition varies from 1.5 to 5.0 days, and that of oviposition from 11.5 to 116.0 days.The initial temperature of egg,larvae and pupae development is 12.4 and 12℃, and the effective accumulative temperature of them is 69.192 and 125℃,respectively.
