粮油等作物与棉花插花种植、间作套种或种成诱集植物带,对棉田害虫有明显的生态控制作用。种植诱集植物有双重作用:一是直接诱杀害虫,减轻其在棉花上的发生危害:二是诱集天敌取食害虫。诱集植物比棉花提前播种或同期播种都可,但提前播种效果更好。诱集植物主要是在棉花生育前期利用效果较好,一般在6月底以前铲除,以不影响棉花生长 Crops such as grain and oil are planted with cotton flower intercropping, intercropping or planting to induce plant belts, which have obvious ecological control effects on pests in cotton fields. Planting trap plants have a dual role: First, direct trapping and killing pests to reduce their occurrence on the cotton damage: the second is to attract natural enemies to eat pests. Trapping plants may be sown earlier than cotton or sown in the same period, but sowing in advance is better. Trapping plants is mainly used in the early stage of cotton growth is better, generally eradicated before the end of June, in order not to affect the cotton growth
