摘要(Abstract)：
在个旧白沙冲南松抚育间伐试验林进行昆虫捕获量研究 ,共获得 11个目的昆虫 ,其中鳞翅目、同翅目、半翅目及双翅目类为优势类群 ,占昆虫类群全捕量的 74 5 9% ,是该林区昆虫类群的主体。昆虫数量与不同强度间伐后的林分类型和该林分松小蠹危害程度有一定的关系 ,间伐林分昆虫种群密度高 ,昆虫捕获量大 ,松小蠹危害很低。而不间伐林分 ,昆虫种群密度小 ,昆虫捕获量少 ,松小蠹危害明显高于间伐林地
Research was conducted on insect catch in Pinus yunnanensis after intermediate cutting at Baishachong of Gejiu,and the insects from 11 orders were caught,among which insects from Lepidoptera,Homoptera,Hemiptera and Diptera were dominant,accounting for 74.59% of total caught insects.The amount of caught insects was related to the intensity levels of intermediate cutting and the damage of Tomicus piniperda,the stands that had received intermediate cutting had a larger catch of insects and a lower damage of T.piniperda than the stands without intermediate cutting.
