摘要
在皖南宣州马尾松林设立标准地，通过冬前放菌，定期调查、取样和检测，并以酯酶同工酶技术鉴别株型，研究了球孢白僵菌在皖南林区越冬马尾松毛虫种群中的宿存，评价了“带菌越冬”措施的致病效果。结果表明，冬前放菌后，白僵菌可在寄主表皮及其林区环境中越冬宿存，但对松毛虫春季发病没有明显加速作用。
In Xuanhou,southern Anhui,plots were established,treated with Beauveriabassiana,investigated and sampled regularly,survival of the fungus in plantations was stud-ied in the aproach of isolate identification by esterase isozyme technique,and the efficacy ofapplication method by overwintering B.bassiana in pine plantations was evaluated.The result8howed that B.bassiana conidia survived on host cuticle and in forest environment,but didnot either cause an epizootic or speed up the pathogenesis.
