利用生命表法研究一种人工饲料条件下茶尺蠖的生长发育和繁殖。结果表明：人工饲料饲养条件下茶尺蠖能够正常生长发育，幼虫存活率、蛹羽化率和卵孵化率分别为90.50%、86.29%和91.03%，与茶树嫩梢饲养比较差异不显著。人工饲料饲养幼虫化蛹率为85.52%，低于茶树嫩梢饲养87.50%的化蛹率。取食人工饲料的茶尺蠖幼虫历期和世代历期分别为20 d 和39.62 d，较茶树嫩梢饲养历期分别增加了1.44 d 和2.41 d，但两者无显著差异。人工饲料饲养茶尺蠖雌成虫寿命显著高于对照，单雌产卵286.9粒，较茶树嫩梢饲养增加14.82%。幼虫种群存活率曲线呈死亡率-年龄增函数，死亡主要发生在后期（化蛹）个体中，与茶树嫩梢饲养差异不显著；实验种群生命表参数种群内禀增长力和周限增长率分别为0.113和1.119，平均世代周期和种群加倍时间较茶树嫩梢饲养增加了2.43 d 和0.265 d，种群趋势指数87.21，表明采用人工饲料饲养的茶尺蠖种群数量呈显著上升趋势。

The growth and reproduction of tea geometrid, Ectropis obliqua Prout, fed on an artificial diet were studied. The results showed that the larvae grew and developed normally fed on the artificial diet. Larvae survival rate, eclosion rate and hatchability were 90.50%, 86.29% and 91.03% respectively. There were no significant difference comparing with that reared with tea tender shoots. The pupation rate of larvae those fed with the artificial diets was 85.52%, lower than those fed with tea tender shoots. Duration of larvae and generation fed with artificial diet were 20 d and 39.62 d, the duration of larvae was postponed 1.44 d and 2.41 d compared with the control. Numbers of eggs oviposited by female adults fed with artificial diets were 286.9 per female, 14.82 percent higher than those fed on tea teder shoots. Survival rate curve of larvae showed an increasing function of mortality-age, no significant difference from the curve of larvae fed on tea tender shoots. The intrinsic rate of increase (Rm) and finite rate by increase (λ) in population were 0.113 and 1.119. The larvae mean generation time (T) and double time (DT) in <br> population fed with artificial diets prolonged 2.43 d and 0.265 d in comparison with the population fed with tea shoots. Population trend index (I) was 87.209, indicated that the population of E. obliqua fed on artificial diet showed the ascending trend.
