借界头烟蚜茧蜂养殖及扩繁点提供的条件,在不同的繁蜂方式下用不同的烟蚜茧蜂蜂源对烟蚜的寄生差异进行了研究,结果表明用传统单株繁蜂的方法接棚壁上的成蜂寄生效果和形成僵蚜明显高于其他处理,其次是接僵蚜,再次是CK,而接烟株上的成蜂寄生效果最次,但形成僵蚜量却明显大于CK。而用高密度繁蜂的方法接僵蚜的寄生效果和形成僵蚜量效果显著,其次是接烟株上成蜂,高密度繁蜂在不同蜂源下的防效高于单株繁蜂。
Parasitization of the tobacco aphid Braconid bee breeding and propagation conditions provided by different bumble bee ways with different Aphid parasitoids bees parasitic differences on the myzus persicae research results show that the use of traditional single bee The results showed that the bee parasitism effect and the formation of stiff aphid were obviously higher than other treatments, followed by the stiff aphid, again CK, and the highest parasitic effect on the tobacco plant, Obviously greater than CK. However, the parasitic effect of the aphid and the formation of aphid were significant with the method of high-density bumble bee, followed by that of the bee-stinging and the high-density bumble bee under different bee sources.
