1994～ 1 999年在新疆皮山县进行了利用麦田天敌控制棉田蚜虫试验研究。结果表明 :在小麦田喷施选择性杀虫剂抗蚜威 ,能够减少麦田蚜口密度及基数 ,有效防治麦田蚜虫为害。同时因为减少甚至阻断了麦田蚜虫天敌食料来源 ,迫使麦田天敌向棉田迁移 ,使棉田蚜虫种群数量显著降低 ,基本控制在防治阈值和经济允许损失水平以下。利用麦田天敌控制棉田蚜虫是棉花实现稳产、高产和降低成本的重要途径 ,能够实现经济和生态效益同步增长
1994-1999 in Pishan County, Xinjiang, the use of wheat field natural enemies to control cotton aphids experimental study. The results showed that the application of the selective insecticide pirimicarb in the wheat field could reduce the density and the base of aphids in the wheat field and effectively control the aphids in the wheat field. At the same time, because of reducing or even blocking the source of aphid natural enemies, the natural enemies of wheat field were forced to migrate to the cotton field, which significantly reduced the population of aphid populations in cotton field. The basic control was below the control threshold and the allowable economic loss level. Using natural enemies of wheat fields to control aphids in cotton fields is an important way for cotton to achieve stable yield, high yield and reduce costs, which can simultaneously increase economic and ecological benefits
