摘要
通过挂笼试验研究了悬挂布氏白僵菌无纺布菌条和喷雾两种不同放菌方式对光肩星天牛成虫的死亡率、产卵量和白僵菌活孢率的影响,并研究了在自然条件下无纺布菌条的带菌量变化情况。结果表明,无纺布菌条放菌方式对成虫的杀伤力明显高于喷雾放菌,尤其是在放菌3～7d后;成虫产卵的刻槽数也明显低于喷雾组;在自然条件下,菌条上的孢子的活孢率和喷雾放菌间差异显著。
In the present paper, different ways for releasing Beauver ia brongniartii against the Asian longicorn beetles, Anoplophora glabripennis, were studied. The result showed that application of nonwoven fabric bands impregnated with the fungus killed more beetles than spray of conidia scraped of f the bands, especially in the 3rd to 7th day after application and less oviposi tion were found in the fungal bands. The germination of the conidia on the fung al bands was higher than that of the sprayed conidia under natural condition.
