摘　　要：20 0 1～ 2 0 0 3年在福建省云霄县进行了白僵菌超低容量油剂林间防治马尾松毛虫后对生物多样性的影响研究 (包括使用前后的物种丰富度S、个体数N、多样性指数H’、均匀度指数R和优势度指数D等 ) .结果表明 ,未防治区和白僵菌油剂防治区的物种数分别为 4 73种和 392种 ,而化学防治区的物种数只有 2 6 6种 ;白僵菌油剂防治区天敌和害虫个体数与未防治区的比例相近 ,分别为 0 10 4 9∶1和 0 10 5 1∶1,明显高于化学防治区 (0 0 5 5 8∶1) ;化学防治和白僵菌油剂防治均降低了物种的丰富度和多样性 ,同时也增强了物种的优势度 ,但化学防治区与未防区的差异显著 ,白僵菌油剂防治区与未防区的差异不显著 。In 2001～2003,an ultra low volume (ULV) Beauveria bassiana (Bb) oil formulation was used to prevent against Dendrolimus punctatus,and its effect on biological diversity (species richness,individual number,species diversity index and evenness index,and dominant index) was investigated.The results showed that there were 473,392 and 266 species in non-control,Bb control and chemical control areas,respectively.The individual number ratio of natural enemies to pest in Bb control area (0.1049∶1) was close to that in non-control area (0.1051∶1),but much higher than that in chemical control area (0.0558∶1).In Bb- and chemical control areas,the species richness and diversity decreased,but dominant index increased.There existed significant difference between chemical control and non-control areas,but no significant difference was found between Bb control and non-control areas.ULV Bb had no obvious effect on the natural enemies and non-target insects.
