| 摘 要： | 通过室内编号控制饲养、田间定点、控制观察,明确大鸢尺蠖(Ectropis excellens Butler)在湖南长沙一年发生五代,以蛹在茶丛树冠下土内越冬,次年3月上、中旬羽化,交配产卵。各代幼虫分别于4、6、7、8、9～10月发生。以第一代和第五代为害期长,平均每头幼虫一生取食叶片面积为17256.6mm2。本文报导此虫的生物学特性和无公害防治措施。

| Abstract: | Through indoors control feeding and on-the-spot field observation,it's confirmed that Ectropis excellens Butler occurs five generations in one year. It overwinters in the form of pupal right under the tea plant's growing soil. It eclosions in the middle of next March,mates and lays egg . Each generation of larva occurs respectively in April,June,July,August,September and October. The first and the fifth generation damage tea plants longest. The larva averagely takes in 17256.6mm2 of tea leaf. The article reports its biology and the pollution free measures to control it. |
