为控制麦田蚜虫为害，保护生态环境，监测了历年麦蚜和主要天敌种群动态，分析表明天敌和标靶害虫麦蚜的发生高峰期具有跟随性，自然条件下利用天敌控制麦蚜能力弱。以增强麦蚜天敌资源数量和控制能力为目的，设计了农林复合生态系统关联模式、间插关联植物延续食物链模式、增殖寄生性天敌补充田间数量等一系列试验。结果表明：对招引瓢虫早春产卵、瓢蜂蚜发生同步、扩大天敌生态位宽度、天敌迁徙越冬等具有明显功效，实施“保护瓢虫、释放蚜茧蜂，喷施虫霉菌”相组合生物措施，可有效控制麦蚜为害，避免害虫再度猖獗，对保护农田生态环境具有重大作用。

Results about research of wheat aphid in past year and dynamic monitoring of main natural enemy for controlling wheat aphid and protecting ecological environment showed that, natural enemy appeared following with the peak of target pest and wheat aphid. It had little control effects on wheat aphids by natural enemy under normal conditions. Many models were studied, such as complex agricultural-forest ecosystem association model, interval planting connected plants to continue the food train model and breeding parasitoids for the complement of natural enemy quantity in field, et al. The result showed that these model had obvious effect on attracting ladybird spawning in early spring, ladybird, aphid parasitoids and Aphid appeared synchronously, extending niche breadth of natural enemy and the migrating and overwintering of natural enemy. Biological technology, for instance protecting lady beetles, releasing aphid parasitoids and spraying bulg mold, which could control the harmful of wheat aphid, overcome pests harmed for the second time, and it had major role on protecting ecological environment.
