摘　　要：苏云金杆菌油悬浮剂主要用于地面器械和飞机的超低容量喷雾,特别适宜于森林害虫的防治。笔者对苏云金杆菌油悬浮剂超低容量喷雾指标进行了测定。室内:雾滴容量中径(Dvm)和数量中径(Dnm)分别为85.57μm和115.24μm,扩散比(DR)为0.74;室外:雾滴DvmΦ1.2为74.86μm、DnmΦ1.2为60.64μm、DvmΦ0.8为78.44μm、DnmΦ0.8为65.43μm,扩散比DRΦ1.2和DRΦ0.8分别为0.81和0.83,杀虫效果(第7天)为73.75%～88.82%;各项性能指标均符合超低容量喷雾的要求。The oil-based suspension of Bacillus thuringiensis is mainly applied to the ultra low volume spraying of mist sprayer and aeroplane,especially apt to control forest pest insect.The result showed,through the test for indexes of the oil-based suspension of Bt on ULV spraying,all indexes accorded with the need of ULV spraying,there are D_(vm)=(85.57?μm)、D_(nm)=115.24?μm,DR=0.74;in field;D_(vmΦ1.2)=74.86?μm,D_(nmΦ1.2)=(60.64?μm),D_(vmΦ0.8)=78.44?μm,D_(nmΦ0.8)=65.43?μm,DR_(Φ1.2)=0.81,DR_(Φ0.8)=0.83,insecticidal effect is (73.75%)～88.82% on 7th day.
