摘要
试验结果表明 :在松墨天牛Monochamusalternatus 2至 3龄幼虫期 ,按 1∶4的虫蜂比 ,于晴天的 11至 15时在林间投放管氏肿腿蜂Sclerodermaguani效果好。当年寄生率达到 81 3% ,第 2年仍有 5 3 5
In the 2nd and 3rd stadia of Monochamus alternatus larvae,Scleroderma guani was released between 11∶00 and 15∶00 in the forest against the sawyer.The proportion of sawyers to wasps was (1∶4).The result showed the parasitization in the year reached 81.3% and remained 53.5% the next year.
