摘要
进行了六盘山翠金小蜂Tritneptis liupanshanensis Yang的人工繁殖及对其防治落叶松叶蜂Pristiphoraerichsonii(Hartig)试验。结果表明,以落叶松叶蜂虫茧为寄主进行人工繁殖,获得接蜂最佳茧蜂比为1︰3。按虫蜂比不同处理释放所繁育的六盘山翠金小蜂防治落叶松叶蜂越冬虫茧,第2年春检查害虫茧被寄生率为58.47%~84.51%,比自然寄生率提高41.08%~67.12%,第3年春小蜂寄生率为52.63%~71.73%,比自然寄生率提高33.37%~52.47%,并获得最佳释放虫蜂比为1∶5。因此,利用六盘山翠金小蜂防治落叶松叶蜂,控制效果明显。
The Tritneptis liupanshanensis Yang, the artificial propagation and its prevention and control of larch sawfly Pristiphora erichsonii (Hartig) test. The results show that the artificial propagation of larch sawfly cocoon as the host, get connected bee Braconidae ratio of 1:3. Release breeding insects bee different treatment the Liupanshan Tsui Nasonia control of larch sawfly overwinter cocoon, the first two in the spring to check pests cocoon parasitism rate of 58.47% ~ 84.51% 41.08% ~ 67.12 than the natural rate of parasitic %, the first three years of spring wasps parasitic rate of 52.63% ~ 71.73% 33.37% ~ 52.47%, than the natural rate of parasitic, and the best release of insects bee ratio is 1:5. Therefore, the use of the the Liupanshan Tsui Nasonia control of larch sawfly, control effect is obvious.
