甜菜白带螟是我国中部地区甜菜普遍发生的一种害虫,据1980年调查,近年危害最重的是陕西渭南地区,尤其在种植年限较久的产区,每年危害面积几乎达百分之百,块根产量损失40—50％,含糖降低1—3度。因此,自1977年开始对白带螟进行了低毒高效农药筛选和试验,结果以乙酰甲胺磷的效果最突出,现将结果整理如下: Beetle borer is a common pest of sugar beet in central China. According to the survey in 1980, the weakest area in recent years is Weinan in Shaanxi Province, especially in the growing areas where the planting time is longer. The annual damage area is almost 100%, and the yield loss of tuberous roots 40-50%, reducing sugar 1-3 degrees. Therefore, since 1977, low toxicity and efficient pesticide screening and testing of the white-bellied borer, the results of the most prominent acephate results are as follows:
