通过连续２ａ的系统研究,筛选出对松墨天牛引诱活笥最强的Ｍ９９－１引诱剂,其主要成分为单匝烯、乙醛、丙酮和有机溶剂。在松墨天牛成虫期,每个诱捕器可诱捕１５１．５头天牛成虫,平均降低下代卵量１２０４．４粒。该引诱剂对监测松墨天牛成虫种群密度及其携带松材线虫数量和防治天牛危害具有重要作用。
Studies on selecting Monochamus alternatus attractant were made from 1998 to 1999.The results showed that the attract ability of the attra tant M 99 1 to the pine sawyer adult is the strongest.Main componentes of the attractant M 99 1 were terpent,acetaldehyde and acetone.Each trap can catch 151.5 pine sawyers in average,and the amount of egg declined by 1 204.4 .It is concluded that this attractant played an important role in monitoring the population density of M.alternatus ,the amount of adult carring Bursaphelenchus xylophilus and controling the pine sawyer.
