为了得到大量用作实验室繁殖的川硬皮肿腿蜂Scleroderma sichuanensis Xiao种蜂,并提高双条杉天牛Semanotus sinoauster Gressitt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。
In order to obtain a large amount of Labile Scleroderma sichuanensis Xiao species of bee for laboratory breeding and to improve the biological control effects of Semanotus sinoauster Gressitt, The research on the rejuvenation technique of Streptococcus nephotettix was carried out and the differences of search parasitism between Chuan scleroderma before and after rehmannia test were tested in the laboratory. The results showed that during the process of laboratory culture of Culter albopictus, it was found that the morphological appearance of the caterpillars was about 10 days earlier than the wild environment. The results showed that the average search rate of C. sinensis collected from the field was 39.33% and the parasitism rate was 37.33%. After rejuvenation The average searching rate of Sichuan bees was 38.11%, and the parasitism rate was 34.4%. There was no significant difference in search parasitism between the two species. However, the average searching rate of Tenebrio molitor breeding was 30% and the parasitism rate was 24.4%. There was a significant degenerative phenomenon in search parasitism.
