1980～1983年在新疆玛纳斯调查,发现冬麦田天敌很多,仅捕食的每亩常在万头以上,其中蜘蛛、瓢虫、食虫蝽是主要类群。蜘蛛的发生与飞虱、叶蝉等关系密切,并以齿须微蛛占优势,该蛛5月底6月上旬达高峰。瓢虫以七星瓢虫为主,多异瓢虫次之,均在麦田繁殖一代,以6月上、中旬幼虫最多,是控制蚜害的主力。麦田蚜茧蜂主要为多脊蚜茧蜂和菜蚜茧蜂,其发生与蚜虫种类、密度有关,蚜害盛期其寄生率有限,但仍可在综合防治中发挥一定的作用。
From 1980 to 1983, Manas survey in Xinjiang found that there are many natural enemies in winter wheat fields. The predation rate per mu is only 10,000 or more. Spiders, ladybugs and bugs are the main groups. The occurrence of spiders and planthoppers, leafhoppers and other closely related, and in order to be predatory teeth micro-spider, the end of May the end of June peak. Ladybugs are mainly ladybugs, ladybugs are the second, all breed in the wheat field, with the largest number of larvae in mid-June, which is the main force controlling the aphids. The main aphid Braconidae in the wheat field are Aphelenchoides versicolor and Aphanizomenon aphid. The occurrence is related to the species and density of aphids. The parasitism rate is limited in the period of aphid infestation, but it can still play a role in the integrated control.
