【Abstract】 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.更多还原
