| 摘 要： | 本文报道了落叶松绶尺蠖（ＺｅｔｈｅｎｉａｒｕｆｅｓｃｅｎｔａｒｉａＭｏｔｓｃｈｕｌｓｋｙ）的生物学特性及生活史。此虫在黑龙江省１年一代，以蛹在枯枝落叶层下越冬，多危害郁闭度较大的落叶松人工林，尤以中龄林受害最重，成虫子５月下旬为羽化始盛期，６月３日左右为羽化盛期，７月１３日左右羽化结束。雌雄比为１：１．１。成虫羽化后即交尾，交尾时间一般在２３时以后，卵多产在落叶松枝条上，少数产在针叶及树皮缝里。雌蛾平均产卵量为５８．６粒。雄虫寿命平均３．９ｄ，雌虫平均寿命５．６ｄ。幼虫共６龄，子８月上旬开始化蛹，８月下旬化蛹结束。

| Abstract: | This paper covered the habit and the life cycle of Zethenia rufescentaria Motschulsky.This pest happened one generation a year in Heilongjiang Province,overwintered under the litter by pupae.Most of them damaged larch plantation inhigh shade, especially the middle aged trees.Emergence for adults began in thelate May; the peak of the emergence is on June 3;and the end of the emergencewas on July 13. The sexual ratio was 1:1.2.The adults mated after 11 o'clockpm,as soon as they emerged. The eggs Were laid on the blanches, the needlesand crabs of the bark.The average amount of eggs was 58.6/insect.The life-span was 3.9 days for male,and 5.6 days for female,The larvae gave sixinstars,the pupation was between early August and late August. |
