摘  要:
1992~1994年,在浙江马尾松林里进行昆虫及蜘蛛群落、松毛虫天敌和种群动态的研究,结果查明:①15年生马尾松针叶立体分布,确认砍枝取薪以留7轮为好,不低于留4轮;②马尾松林昆虫群落分属18目118科,其中直翅目、鞘翅目、同翅目、膜翅日、半翅目占优势,经测定,龙游县群落结构复杂、分布均匀,群落与层次、坡向、郁闭度、灌层盖度关系密切;③蜘蛛群落分属19科46种,其中蠨蛸科、猫蛛科和蟹蛛科占优势,经测定,冠下层比冠层蜘蛛群落结构复杂、分布均匀,群落与松林不同层次、郁闭度、海拔、坡向等因子关系密切;④松毛虫寄生性天敌:卵期7种,寄生率12.24%,幼虫期7种,寄生率5.83%,蛹期14种,寄生率主3.790%。天敌与松毛虫虫口密度密切相关。采取以营林措施为基础的综合治理方法,改变了马尾松毛虫周期性猖獗现象,14年的综合治理,取得了显著的效益。

摘  要:
Study on insect and spider population, natural enemy and population dynamic in masson pine (Pinus massoniuna) forest of zhejiang province from 1992 to 1994 resulted that: 1. determination of storey distribution of pine leaf, 7 whorls should be left, at least 4 whorls; 2. insect population of masson pine forest belong to 118 families of 18 orders, among which, Orthoptera, Coleoptera, Homoptera, Hymenoptera, Hemiptera were dominant; 3. spider population belong to 46 species of 19 families, among which dominant were Oxyopidae, Thomisidae, etc.; 4. parasite enemy of Dendrolimus punctatus: 7 species during egg period with 12.24% parasited rate, 7 species during larvae with 5.83% of parasited rate, 14 species during pupal stage with 13. 79% parasited rate. Comprehensive measurement were applicated to control periodical occurrence of D. punctatus damage.
