| 摘 要： | 龙山林场松毛虫天敌的种类繁多,从蜘蛛、昆虫、病菌到鸟类,构成一个极其复杂的天敌综合体。从两年四代生命表中可清楚地看出天敌的作用。在各类死亡因子中,最主要的是幼虫期的捕食性天故和其他一些死亡因子,所造成的死亡率平均为78％,根据天敌作用的系统考查,初步认为生物因子是这个周期(1984—1985年)松毛虫虫口下降的主导因子。

| Abstract: | Biotic factor is a very important factor in insect population dynamics, which is also a necessity in the research of IPM of masson pine moth Dendrolimus punctatus. The results are as follows:There are a lot of natural enemies of masson pine moth, including spiders, insects, microorganisms and birds. They form a complicated complex of natural enemy. There are several lethal factors in the life table, which has been conducted for two years (1984-1985). 78% of the larvae are killed by predators and migration etc. after egg hatching, which form a main lethal factor in the life table. According to the systematic investigation on the influence of natural enemies. Biotic factor is supposed to be the main factor in the population dynamics of masson pine moth in 1984-1985. |
