通过1979—1982年室内试验和田间调查结果表明,6月上、中旬当气温达20℃以上时,成虫出现高峰,进入发生盛期.此时要做好成虫预报工作,及时进行防治.在成虫发生期,平均每百米垅长数量超过10头(雌雄比例近1:1).第二年局部地块将遭幼虫严重为害,每百米垅长不足10头成虫,第二年局部地块会受中度或轻度为害,而百米垅长只有2—3头成虫时,大部份地块不受害.幼虫的越冬密度大小,是第二年防治指标.一般成虫发生量大,幼虫越冬密度也大.7月份总降雨量达150—200毫米时,成虫发生量大幼虫越冬密度也大.但此时总降雨量在60—80毫米时,尽管成虫发生量多,幼虫越冬密度反而减少.豆茬或隔年豆茬幼虫越冬密度大,如种甜莱,当测得每平方米有0.5—1头幼虫时,必进行防治。成虫的防治,以辛硫磷乳剂800倍液,防效达90％以上。幼虫防治,以3％呋喃丹或3％甲基异柳磷颗粒剂,亩用1.5—2公斤,随种入土,当每平方米有蛴螬1—4头时,保苗率达78％以上。如超过5头,适当增加用量.
The results of laboratory tests and field surveys from 1979 to 1982 showed that when the temperature reached 20 ℃ or above in mid-June, the adults peaked and entered into the peak period, at this time, the adult predication work should be done and the prevention and treatment should be carried out in time. In the period of occurrence, the average length of each hundred meters long is more than 10 (the ratio of male and female is nearly 1: 1). In the following year, the local plots will be severely damaged by larvae, with less than 10 adult worms per 100 meters long. Will be moderate or mild damage, and 100 meters long only 2-3 head adult, most of the plots are not affected. Larvae overwintering density size is the second year prevention and control index. Overwintering density is also large in July when the total rainfall of 150-200 mm, adult large larvae overwintering density is also large, but this time the total rainfall of 60-80 mm, despite the occurrence of adult more, the overwintering density of the larva instead Reduce stubble or stubble beans next year, the density of overwintering larvae, such as sweet and sour, when measured per square meter 0.5-1 larvae, will be controlled. Adult prevention and control to phoxim emulsion 800 times, anti-efficiency of more than 90%. Larvae control, with 3% carbofuran or 3% methyl isofenphos granules, mu with 1.5-2 kg, with the planting of soil, when per square meter with 蛴 螬 1-4 heads, seedling protection rate of 78%. If more than 5, an appropriate increase in dosage.
