马尾松林昆虫及蜘蛛群落的研究报告

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分析。结果表明：（１）１５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，膜翅目，半翅目占优势，经测定，龙游县落结构复杂，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，其中萧蛸科，猫蛛科和蟹蛛科

Study on Insect and Spider Population in Masson Pine (Pinus massoniana) Forest

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.
