摘　　要：利用苏云金杆菌的新剂型———油悬浮剂进行防治马尾松毛虫试验 ,试验结果表明 :该剂每hm2 3 0 0 0mL、45 0 0mL、60 0 0mL 3种施药量 ,其防治效果在 1 %显著水平下与 40 0 0倍敌杀死比较差异显著。Oil-based suspension, a new formulation of Bt was used to control Dendrolimus punctatus. The results showed that control effects of oil-based suspension for Bt with pesticide application rates of 3 000 mL, 4500 mL and 6 000 mL per hm 2 were relatively siginificantly differed from that by Decis under 1% of significant level.
