| 摘 要： | 棉田中间种红花带,利用红花上的桃蚜,招引、繁殖大量草蛉,以控制棉田蚜虫,取得很好效果。红花田内草蛉成虫最多年份每亩达4万多头。不间种红花的对照田,从5月开始,用药7次。在棉蚜高峰期,蚜害株和卷叶率均比间种红花田严重。间种红花的棉田,经济效益有所增加。

| Abstract: | Safflower (Carthamus tinctorius), a Chinese herb used for Medicine and edible oil, was interplanted in cotton fields as a means of augmenting Chrysopa app. in Yixian County. Safflowers naturally infested by peach aphid, Myzus persicae. attracted aa many lacewinga aa 41,000/mu. The lacewinga multiplied and exerted effective control on the cotton aphids. In contrast, the aphid infestation rate of the monocropping plots was significantly higher than that of the intercropping plots, although 7 sprays of insecticides were applied in the former. |
