新疆农业生态系统中,防护林等树木、小麦等夏熟作物、农田边缘区及绿洲内野生植物、各种果树是现今棉蚜的主要源库。建设和完善农田和绿洲防护林体系,扩种果树、农田四周种植增殖天敌的植物,可有效增强棉蚜天敌的数量。防治林木、果树、小麦等的害虫,应尽量采用保护天敌的有效措施。田外野草应注意保护,防止盲目铲除;防治棉叶螨不宜提倡田边喷药,设置所谓保护带。棉蚜的生物防治,更应注意田内、田外的协调,充分发挥生态防治棉蚜的作用。
Xinjiang agro-ecosystems, trees such as shelterbelts, summer ripe crops such as wheat, farmland marginal areas and wild plants within the oasis, all kinds of fruit trees are the main source of cotton aphid today. The construction and improvement of shelterbelt and oasis shelterbelt system, the expansion of fruit trees, and the planting of plants that proliferate natural enemies around the farmland can effectively increase the number of natural enemies of cotton aphids. Prevent trees, fruit trees, wheat and other pests, should try to adopt effective measures to protect natural enemies. Field weeds should pay attention to protection against blind elimination; prevention and treatment of cotton spider mites should not be sideline spraying, set the so-called protection zone. Cotton aphid biological control, but also pay attention to the field, field coordination, give full play to the role of ecological control cotton aphid.
