第 30 卷第 2 期 2008 年 3 月 Vol.30 No.2 Journal of Tangshan Teachers College Mar. 2008 九种化学药剂与球孢白僵菌相容性的研究 顾丽嫱，李春香，林 杨 （唐山师范学院生命科学系，河北 唐山 063000 ） 摘 要：测定了 9 种化学药剂在田间常规浓度下对球孢白僵菌孢子萌发、菌丝生长以及产孢量的影响。结果 表明，杀虫剂与球孢白僵菌的相容性好于杀菌剂。杀虫剂除尽、康夫、甲维盐、铁沙掌对白僵菌孢子萌发和菌丝 生长的抑制小，混用时孢子萌发抑制率均小于43% ，对菌丝生长抑制率分别为-1.79%、11.11%、17.73%、26.57% ， 且产孢量均高于对照，因此与白僵菌相容性较好。杀菌剂美生、甲霜灵、新霜疫克、百菌清及杀虫剂强棒对白僵 菌孢子萌发和菌丝生长的抑制作用大，产孢量低，因此与白僵菌相容性较差。 关键词：球孢白僵菌；化学药剂；相容性 中图分类号：Q939.9 文献标识码：A 文章编号：1009-9115(2008)02-0048-03 Compatibility of Nine Common Chemicals with Beauveria Bassiana GU Li-qiang, LI Chun-xiang, LIN Yang (Department of Biology Science and Technology, Tangshan Teachers College, Hebei Tangshan 063000, China) Abstract: The effect of common chemicals at conventional field use concentrations on conidial germination, mycelial growth and conidial product of Beauveria bassiana (Bals) Vuill were discussed. The results showed that the insecticides were more compatible with B.bassiana than the fungicides. Insecticides like chlorfennapyr, cyfluthrin, emamectin benzoate, imidacloprid, had lower effect on the conidia germination and the mycelia growth of B. bassiana, the germination inhibition was low than 43%, mycelia growth inhibition were -1.79%, 11.11%, 17.73%, 26.57%, and the amount of spore product exceed CK, indicating the good compatibility with Beauveria bassiana . All of the fungicides and one of the insecticides (abamectin) had higher effect on the conidia germination and the mycelia growth of B.bassiana, had lower conidial product, and could not be used together. Key words: Beauveria bassiana (Bals) Vuill; com
