| 摘 要： | 天幕毛虫是果、蚕、林业的大害虫，越冬卵孵化能形成明显的高峰期，并与毛叶迎红杜鹃的盛开前期相吻合。１～３龄幼虫吐丝结幕群居生活，４龄后迁移分散，转移寄主，４～５龄取食量约占总取食量的９５％，结茧化蛹于迁移后的寄主上。成虫嗜好在辽东栎、蒙古栎上产卵，在柞蚕场内卵块分布有其规律性，成虫有较强的趋光性。天敌有２０余种，其中寄生蝇、卵寄生蜂、核型多角体病毒等对此虫的发生数量有很大的抑制作用

| Abstract: | Matschulsky tent caterpillar is a nuisance in the forest, orchard and on tussah farm. The overwintering eggs may form a hatching peak, which happens simultaneously just with the full bloom period of the ciliate mucronulate rhododendron. The larvae of 1-3 instar spin a silk tent and live together, but migrate, separate and transfer to other hoats at 4 instar. Their eating capacity at 4-5 instar accounts for 95% of the tatal. The caterpillar makes cocoon and changes into chrysalis on the transfered host. The phototropic imago loves to lay eggs on Mongolian or Liaodong oak trees. The distribution of egg lumps follows their own rule on tussah farm. The pest has some 20 species of natural enemies. Among them, the parasitic flies, egg wasps and nucleo-polyhedronic virus play an important role in controlling the pest |
