用性信息素诱捕法防治槐小卷蛾研究

林间试验研究了用合成性信息素（反，反）－8，10－十二碳双烯－1－醇（E8，E10－12，OH）和（反，反）－8，10－十二碳双烯乙酸酯（E8，E10－12，Ac)(2:3)诱捕法防治行道树害虫槐小卷蛾（Cydia trasias Meyrick)的防治效果，诱捕区长500米，宽40米，三角形粘胶诱捕器悬挂在距地面约3m的国槐树侧枝上，诱捕器间距约15m，共悬挂62个诱捕器，对照区长250m,与诱捕区相距400米，防治效果用活雌蛾诱捕器，粘翅活雌蛾交配率以及国槐叶柄和果荚的受害率进行评价，槐小卷蛾一年有3次成虫发生高峰期，雌雄性比接近1：1，在诱捕区内，越冬代，第一代和第二代成虫发生期间分别诱集到雄蛾2268，2149和2342头，在越冬代和第二代成虫发生盛期，诱捕区内活雌蛾诱捕器诱捕雄蛾的数量比对照区明显减少（P＜0．01），诱捕区内粘翅雌蛾的交配率比对照下降86．0％，在第一代，第二代和第三代幼虫为害盛末期，诱捕区内叶柄及果荚被蛀率分别比对照降低63．51％，68．47％和73．45％（P＜0．01），试验结果表明，用合成性信息素诱捕法防治槐小卷蛾效果明显，前景广阔。

Mass trapping with synthetic sex pheromone for control of the Chinese tortrix,Cydia trasias(Meyrick)

Mass trapping for controlling the Chinese tortrix,Cydia trasias(Meyrick),using synthetic sex pheromone traps was evaluated in one road of shade-tree,Chinese scholar-tree,Sophora japonica L.,in Beijing,China, in 1999.The test plots were located in Zhichun Road,Zhongguancun District.The trapping plot was ca.500m×40m.The triangle sticky traps were hung under the Chinese scholar-tree limbs about 3m above ground at 15m intervals.Totally,62 traps were deployed.Each trap was baited with a lure containing 0.25mg o...
