| 摘 要： | 飞机喷洒青虫菌6号液剂,大面积防治松毛虫的试验表明,常量喷雾用菌剂1125—1500克/公顷和低量喷雾1500—2250克/公顷,2—3天后防效可达90％以上,而且具有明显的后效。但防治区低量喷雾的防治效率比常量快.青虫菌剂对林间天敌昆虫、鸟类、蜜蜂等均安全。

| Abstract: | Airial spraying of B. thuringiensis (#3 Liquid Preparation) to control Dendrolimus punctatus in forests was conducted in Hubei in 1985. Two techniques were experimented: normal volume spraying at 1125-1500g a.i./ha and ultra-low volume spraying at 1500-2250g a.i./ha. Mortalities of the larvae ware over 90% in both techni-ques, though results were more variable with the ultra-low volume apray. The application of Bt #3 Liquid Preparation was safe for natural enemies, birds and honey bees. |
