【摘要】 报道了寄生球果花蝇Strobilomyiaspp .的球孢白僵菌Beauveriabassiana选择性培养基的筛选以及应用该培养基检测土壤中球孢白僵菌动态的研究结果。为有效地检测施用球孢白僵菌防治球果花蝇的土壤中球孢白僵菌的变化 ,以Doberski的选择性培养基为基础 ,筛选出对球孢白僵菌具有较强选择性的选择性培养基 ,可回收土壤中球孢白僵菌孢子达 79 5 %。用该培养基检测球孢白僵菌在施菌土壤中第 2年的存活率为 0 9%～ 2 8% ,它在土壤中有一定的持效性。表 4参 6更多还原

【Abstract】 The culture medium for Beauveria bassiana which parastied in Strobilomyla spp.was selected based on Doberski culture medium.This media had high selection for Beauveria bassiana .Use of this media could collect back 79 5% of the conidia of Beauveria bassiana which added in to surface layer of humus.The collected rate of live conidia was 0 9%～2 8% after two years in soil.It showed that the fungi has a certain sustained effect in the soil for control Strobilomyla ssp.更多还原
