摘要：

明纹柏松毛虫(D end rolim us suffuscus illustratus L a jonqu iere)是侧柏树重要的暴发性食叶害虫。该虫在山西省1 a发生1代,以3龄~5龄幼虫越冬,翌年3月底至4月上旬越冬幼虫开始上树取食。幼虫多为8龄,幼虫期133.5 d,幼虫越冬前期和结茧化蛹前期发育历期较长;雌蛾比雄蛾寿命长,雌蛹蛹期21 d,雄蛹蛹期28.5 d。可结合蜘蛛、食蚜蝇、赤眼蜂、平腹小蜂等天敌对其进行防治。

摘要：

Dendrolimus suffuscus illustratus Lajonquiere is an important pest of heavy consumption to leaf in platycladus orientalis.The pest occurs one generation a year in Shanxi,passes the winter as third～fifth instar larvae.In next year,the larvae begins to climb up tree to feed from the end of March to the beginning of April.The larvae is usually 8 instars,life time of larvae is 133.5 d,the prophase of passing winter as larvae and the prophase from cocoon to pupa are both longer.The lifetime of female moth is longer than male moth,the length of time to female moth is 21 d,while that of male moth is 28.5 d.The pest can be controlled by natural enemies as spider,syrphid flies,trichogram matids,anastus japonicus etc.
