摘　　要：[目的]研究普通草蛉卵低温储存的有效时间.[方法]低温储存普通草蛉卵,分析比较不同储存时间对孵化率、幼虫历期、化蛹率、蛹期及羽化率的影响.[结果]普通草蛉卵在（6±1）℃、RH（60±5）％的环境下低温储存7～13 d,其孵化率、幼虫历期、化蛹率、蛹期、羽化率等各处理间无显著差异.低温储存时间超过15 d,其孵化率、幼虫历期、化蛹率、羽化率出现显著差异.[结论]普通草蛉卵在（6±1）℃、RH（60±5）％的环境下,低温储存天数不宜超过13 d.[Objective] This project aims to study the effective time of cryopreservation eggs of Chrysoperla carnea Stephens.[Method] The influence of the different storage times on the hatching rate,larval duration,pupal rate,pupal stage and eclosion rate after cryopreservation eggs of Chrysoperla carnea Stephens were analyzed.[Result] The hatching rate,larval duration,pupal rate and the pupal stage,the eclosion rate was no significantly different after cryopreservation Eggs of Chrysoperla carnea Stephens at（6 ± 1）℃ and RH （60％ ± 5 ％） for 7to13 days.The hatching rate,larval duration,pupal rate and eclosion rate showed significant difference when the cryopreservation time was longer than 15 days.[Conclusion] The cryopreservation eggs time of Chrysoperla carnea Stephens at （6 ± 1） ℃ and RH （60％ ± 5％） should not be shorter than 13 days.
