摘　　要：比较了采自梨小食心虫卵中的松毛虫赤眼蜂在不同温湿度下的发育历期、成蜂寿命以及平均单雌产卵量、子代雌蜂数。结果显示,不同温、湿度下,松毛虫赤眼蜂发育历期、成蜂寿命、子代雌蜂数量均存在差异。松毛虫赤眼蜂在18~30℃时的发育历期、成蜂寿命随温度的升高而缩短;相对湿度在55%以上时羽化率均在80%以上：高温、低湿条件明显影响松毛虫赤眼蜂成蜂寿命;子代雌蜂数量均在成蜂羽化的第1天达到高峰。随着时间延长,雌蜂数量减少。本研究结果表明,室内繁育梨小食心虫卵松毛虫赤眼蜂的适宜温度为22~28℃,RH〉55%最为合适。This paper compared development period,adult life-span,average amount of spawn,number of female offspring of Trichogramma dendrolimi collected from spawn of Grapholitha molesta under different temperature and humidity.The results indicated that within a temperature range of 18~30 ℃,developmental phase and adult life-span shortened along with temperature increase.Emergence rate was more than 80%over relative humidity of 55%.High temperature and low humidity conditions significantly affected adult life-span.Offspring female rate reached a peak on the first day and then reduced with extension of spawning time.And optimum temperature and humidity for mass rearing of T.dendrolimi were22~28℃ and more than 55%
