摘　　要：以藁城为例,采用淘土、扫网、挂黄板等方法对太行山前平原麦田昆虫群落进行了调查,结果表明该区域超高产麦田昆虫种类相对较少,总计22种,隶属于6目14科。害虫主要有2类,吸浆虫类和麦蚜类。小麦吸浆虫以麦红吸浆虫为主。天敌昆虫常见有蚜茧蜂、食蚜蝇、草蛉和瓢虫4类。采用氧乐果、毒死蜱、高效氯氰菊酯、吡虫啉4种常用药剂对麦红吸浆虫成虫进行了田间药效实验,结果表明上述4种药剂对麦红吸浆虫均有较好的防治效果,虫口减退率均在80%以上。其虫口减退率从高到低依次为:氧乐果、毒死蜱、高效氯氰菊酯、吡虫啉。建议根据麦红吸浆虫的发生情况,选择中低毒药剂毒死蜱、高效氯氰菊酯、吡虫啉交替使用。With Gaocheng as an example, the insect investigated by washing the soil, sweeping, hanging community of wheat field in Taihang Piedmont were the yellow board, etc. The result showed that the species of insects in the field were relatively few, only 22 species of 14 families in 6 orders. According to the severity, the main pests were wheat midge, of which mainly was S. mosellana, and wheat aphids. There were 4 groups of natural enemies, including aphidiidaes, ladybugs, syrphid flies and chrysopids. The efficacy of Omethoate, Chlorpyrifos, Beta-cypermethrin and Imidacloprid in controlling S. mosellana was determined in the field. The results showed that the insecticides all had good control effect, and the reduce rates were over 80%. The reduce rate from high to low in turn was： Omethoate, Chlorpyrifos, Beta-cypermethrin and Imidacloprid. So using medium or low toxicity Chlorpyrifos, Beta-cypermethrin and Imidacloprid alternately based on how seriously S. mosellana happened was suggested.
