摘  要：
观察马尾松毛虫自然种群的发生发展过程时,发现松毛虫往往经过几个世代的低密度潜伏期之后,才发展到大发生阶段,如1972年在缙云壶镇调查,三个世代每株平均蛹数0—11个;1973年的越冬代0.3—2.5个。1980年在长乐林场调查,调查到很多地段老龄

摘  要：
Predators were major mortality factor of natural population of the pine moth, Dendrolimus punctatus Walker during its latent period. Birds, spiders, ants, true bugs and preying mantids were primary predators of the pine moth. Eggs, mature larvae, pupae and adults were mainly attacked by birds as Parus major commixtus Swinhoe; immature larvae were mainly preyed by arthropod predators such as Oxyopes linealipes L. Koch., O. seriatus L. Koch., Poyrhachis dives F. Smith, Formica rufibarbis sinae Emery., Velinus nodipes (Uhied), Lsynadus obscurus (Dallas). The mortality caused by predators was so high(95—100％) that the life cycle of the pine moth was not completed under certain circumstances.
