本文通过室内和田间试验所取得的数据结果表明，天幕毛虫幼虫共分６龄；卵寄生率为５％；室内饲养全幼期死亡率为１００％；感染病毒是幼虫死亡的主要原因。自然生态因子影响幼虫的存活，以１～２龄幼虫死亡率最高，占全幼期死亡率的９１．９％。试验的温湿度对出壳率无显著影响。在适宜温度范围内，温度高寿命短，存活率低。各龄幼虫发育速率随着温度升高而加快，相对湿度在４０．０～９２．０％之间是幼虫生活的适宜湿度范围，１～４龄幼虫发育历期与湿度呈显著直线相关关系。
The data obtained from indoor and field trials showed that the larvae of Anteaterial caterpillar were divided into 6 age groups, egg parasitism rate was 5% and indoor full-term mortality rate was 100%. Infected virus was the main cause of larval death. Natural ecological factors affect the survival of larvae, the mortality of 1 ~ 2 instar larvae is the highest, accounting for 91.9% of the full-term mortality. The temperature and humidity of the test had no significant effect on the hatching rate. In the appropriate temperature range, high temperature, short life expectancy, low survival rate. The developmental rate of larvae at different instars accelerated with the increase of temperature. The relative humidity ranged from 40.0% to 92.0%, which was the suitable humidity range of larvae. The developmental stages of 1-4 larvae showed a significant linear correlation with humidity.
