| 为了得到大量用作实验室繁殖的川硬皮肿腿蜂种蜂，并提高双条杉天牛的生物防治效果，在室内进行双条杉天牛人工养殖的基础上，开展了川硬皮肿腿蜂复壮技术的研究，并进行室内放蜂试验检验复壮前后川硬皮肿腿蜂的搜索寄生能力差异。结果发现，在双条杉天牛的实验室饲养过程中，发现该天牛各虫态出现的时间均比野外环境下早10天左右。通过对川蜂进行连续三代复壮并进行室内放蜂防治试验，结果表明野外收集的川硬皮肿腿蜂对双条杉天牛的平均搜索率为39.33%，寄生率为37.33%，复壮后的川蜂平均搜索率为38.11%，寄生率为34.4%，两者在对双条杉天牛的搜索寄生能力上没有显著的差异。而黄粉虫繁殖的川蜂平均搜索率为30%，寄生率为24.4%，搜索寄生能力存在明显的退化现象。 |
| 英文摘要: |
| In order to get massive Scleroderma sichuanensis Xiao used as laboratory breeding and improve the biological control effect of Emanotus bifasciatus, we carried out cultivation experiment of emanotus bifasciatus and rejuvenescence study of Scleroderma sichuanensis Xiao. And differences of the searching rate and parasitizing rate were tested before and after the rejuvenation in lab. We found that the occurrence time of each longicorn stage was 10 days earlier than in wild environment. Through continuous rejuvenation for 3generations and biological control experiment in lab, results showed that wild wasp’s average searching rate was 39.33% and the average parasitizing rate was 37.33%, whereas rejuvenesced wasp was 38.11% and 34.4%, respectively. No obvious difference on searching and parasitizing rate was found between the two. However, significant degeneration phenomenon was found on Scleroderma sichuanensis Xiao raised by Tenebrio molitor Linnaeus, which average searching rate was 30% and the parasitizing rate was 24.4%. |
