摘　　要：松墨天牛在被害马尾松树上的分布研究表明 :松墨天牛幼虫的数量随胸径的增大而增多 ;带虫株率随胸径的增大而减少 ;幼虫在树干上的分布数量下段 >中段 >梢段 .树干 2 m以下带虫量占整株的 2 0 .35 % ,因此 ,在虫情调查时可以调查 2 m以下的树干来估测全树的虫口密度 .Surveys were given to distribution of Monochamus alternatus Hope larvae on infested pines in the years of 2000 and 2001,the investigation in Dabu forestry farm of Wuyishan city shows that:the bigger the DBH,the more amount of the larvae in the trees and the less proportion of the infested tree;quantity distributions of the larvae in the trunk is lower part>middle part>upper part,the amount of larvae in the trunk of less than 2 m are 20 35% of that in the whole trunk According to the result,investigation and control measure are decided
