| 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 .为虫情调查和综合防治提供科学的依据 |

| Abstract: | 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 |
| Keywords: | Monochamus alternatus Hope vertical distribution Pinus massoniana |
