利用引诱剂防治松墨天牛的研究

Prevention and Cure of Monochamus alternatus with Attractants

用PA－22号，PA－26号引诱剂引诱松材线虫病的传播媒介昆虫──松墨天牛，试验结果表明：PA－22号引诱剂施于诱木上，与邻近的病虫木相比，其诱虫数量提高698．9％，PA－26号引诱别比对照提高740．51％，诱木和对照木的诱虫数量的差异都极显著（P＜0．01），两种引诱剂的引诱效果都很好，而PA－26优于PA－22，在天牛危害的松林里，施引诱剂PA—22号，PA—26号能把分散危害变成集中危害，使诱木的诱虫量比病虫木自然诱虫量提高6～7倍，把诱木内的天牛集中消灭，从而达到防治松墨天牛、控制松材线虫病危害的目的。

Monochamus alternatus was trapped with PA-22 and PA-26 attractants, respecti vely. The results showed the number of Monochamus alternatus in the traping wood treatedby the attractants increased by over 600%, as compared with the controls. Both of the arractants had fine effects and could change scutted damage into Centralized damage, but PA-26 was better than PA-22.
