| 摘 要： | 通过室内饲养和野外调察,明确了槐小卷Cydia trasias(Meyrick)在山东泰安的发生规律,结果表明:该虫在泰安1年3代,以幼虫蛀食国槐(Sophora japonicaL.)等槐属的叶柄及果荚,一头幼虫危害9～12个叶柄,群体爆发时造成大量叶柄脱落、秃枝、果荚变黑,影响国槐的观赏和经济价值。10月份以老熟幼虫在原蛀孔、树皮缝、果荚内越冬。

| Abstract: | The biology of Cydia trasias（Meyrick） in Tai＇ an was observed by rearing large numbers of individuals of C.trasias indoors and field observations.The results show that C.trasias has 3 generations in Tai＇an each year.The larvae of this pest can damage the petioles and seed pods of the Chinese scholar tree（Sophora japonica）;each larva can damage 9-12 shoots during the feeding phase of its life history.During outbreaks,larvae can cause extensive leaf drop,bare twigs and seed pod damage,reducing the ornamental and economic value of trees.They overwinter after October as larvae in seed pods,bark crevices,and twigs of the Chinese scholar tree. |
