| 摘 要： | １９９０年黑龙江省大兴安岭林区发生了大面积落叶松毛虫危害，发生面积达１００多万公顷，根据生产防治工作的需要，对大兴安岭落叶松毛虫生物学特性进行了系统研究，搞清高落叶松毛虫在黑龙江在兴安岭林区为２年发生一代，第１年以２－４龄幼虫越冬，第２年以５－７龄幼虫越冬。经室内饲养测定结果幼虫为９龄，并对卵，幼虫，蛹，成虫的生活习性进行了系统的观察和描述，通过生物学特性的研究为该虫的综合防治提供了理论依据。

| Abstract: | The severe damage caused by Dendrolimus superans (Butler) occured in the vast areas of Daxing'an forest region in Heilonajiang province in 1990. Damaged forest area amounted to 1 million hectare. The authors systematically studied the bionomics of Dendrolimus superans in Daxing'an Mountain and made sure that D. superans occured one generation per two years in the region. It overwintered with 2 to 4 instar larvae in first year, and with 5 to 7 instar larvae in second year. Its larva stage went through 9 instars. The authors systematically observed . and described every development stage of this insect. All these studies provided a basis for IPM of Dendrolimus superans. |
