用苏云金杆菌群(Bacillus thuringiensis)防治花生田蛴螬有较好效果。在经济效益和生态效益上,八号菌(B·thuringiensis var kurstaki)比之常用化学农药优越,5年试验示范效果较稳定。八号菌拌种平均灭虫效果为76.7％,保英效果为70.9％,持效期可达80天以上。菌药防治的药本与净收益之比为1:42.2,而化药防治的为1:23.5。 Bacillus thuringiensis is very effective in controlling peanut fields. In terms of economic and ecological benefits, B. thuringiensis var kurstaki is superior to conventional chemical pesticides and the 5-year experimental demonstration is more stable. On the 8th seed dressing the average pest control effect was 76.7%, Baoying effect was 70.9%, the duration of up to 80 days or more. The ratio of medicine to net income of prevention and cure of bacteria is 1: 42.2, while that of chemical medicine is 1: 23.5.
