摘　　要：利用白杨透翅蛾Paranthrene tabaniformis、杨十斑吉丁虫Melanophila picta和纳曼干脊虎天牛Xylotrechus namanganensis幼虫作为替代寄主对天敌昆虫白蜡吉丁虫肿腿蜂Sclerodermus pupariae进行人工饲养,成功繁殖出了成蜂。人工繁蜂的条件为:温度26℃,相对湿度70%,接蜂的蜂虫比3∶1,三种替代寄主白杨透翅蛾、杨十斑吉丁虫和纳曼干脊虎天牛幼虫的被寄生率分别为43.77%、87.12%和82.41%;平均繁蜂时间分别为42 d、33.17 d和34.58 d;白杨透翅蛾、杨十斑吉丁虫和纳曼干脊虎天牛单个幼虫平均繁殖白蜡吉丁肿腿蜂分别为40.83头、90.33头和50.92头;子代蜂的雌性率分别为95.53%、96.70%和94.57%。在7℃,相对湿度70%的条件下储藏,白蜡吉丁肿腿蜂子代成蜂的平均寿命150 d;寿命超过一个月的雌蜂占95%,雄蜂寿命5-7 d。Sclerodermus pupariae （ Hymenoptera ： Bethylidae） was reared successfully by three kinds of substitute hosts： the larvae of Paranthrene tabaniformis, Melanophila picta and Xylotrechus namanganensis, those can be parasitized 43.77%, 87.12% and 82.41% individually when the hosts were treated under the condition 26℃, RH70% with wasp and host （3 ： 1 ）. The wasp could complete one generation in 42 d, 33.17 d and 34.58 d respectively. The result showed that 40. 83, 90.33 and 50. 92 individuals of the wasp adults could be reared by one larve of P. tabaniformis, M. decastigma and X. namanganensis, and female rate of offspring wasp was 95.53%, 96.70% and 94.57% respectively. The average longevity of the adults of wasp about 150 d under 7℃, RH70% ; 95% of the female wasps could survive more than 30 d, males 5 -7 d in normal atmospheric temperature.
