摘　　要：试验表明5%桉油精500-1500x、25%阿维灭幼脲500-1500x、球孢白僵菌油悬浮剂1000-1500x、1%噻虫啉微囊粉剂、400亿孢子/克球孢白僵菌粉剂均对云杉梢斑螟幼虫有明显杀虫效果。药剂喷烟防治仍然是当前防治天然林区云杉梢斑螟幼虫最佳技术措施之一。The results showed that 5%Eucalyptus 500-1500x,25%abamectin 500-1500x,Beauveria bassiana oil SC 1000-1500x,1%thiacloprid microcapsule powder and 40 billion spore/g Beauveria bassiana powder had obvious insecticidal effect on the larvae of Dioryctirin schutzeella Fuchs.At present,chemical smoke spraying is still one of the best technical measures to control the larva of Dioryctirin schutzeella Fuchs in natural forest area.
