| 摘 要： | 枣尺蠖（Ｓｕｃｒａｊｕｊｕｂａ Ｃｈｕ） 是枣树的重要害虫之一， 其分布与寄主较为广泛， 近年来在我省为害极其严重。该虫在我省一年发生一代， 以蛹在枣树下土壤中和枯枝落叶层中越冬， 翌年４ 月上旬羽化， 羽化高峰期为４ 月８ 日至１７ 日， 一日内以上午７∶３０ ～９ ： ３０ 和下午６ ：３０ ～８ ： ３０羽化最多， 形成两次明显的羽化高峰， 羽化率为７５－４ ％ 。雌雄性比为２－４∶１。成虫交配高峰期为黑暗期１－５～２－５ ｈ， 交配持续时间在正常光周期下多数为３ ～７ ｍｉｎ ， 在控制光周期（１４Ｌ： １０Ｄ）下多数为１５ ～３０ ｍｉｎ。每雌平均产卵量为６４５ 粒

| Abstract: | Sucua jujuba Chu is one of the important pests on Jujube trees,widely found in Shanxi province.In recent years,it increasingly Causes serious damages to forest.The pest has one generation each year.Its pupae overwinter in the soil or under dead leaves and begin to emerge in early April of the next year.The peak period of emergence is from the 8th of April to the 17th of April.It has two emergence peak period in a day ,one is in the 7:30-9:30 a.m and another is in the 6:30-8:30 p.m The emergence percentage is 75 4% ,with a ratio of female to male 2 4:1.The mating peak period is in 1 5-2 5 hour after the dark,and the mating sustaining period of adults is 3-7minutes under ordinary photoperiod and 15-30minutes under 14L:10D photoperiod.On average,each female deposits 645 eggs. |
