摘要
应用聚集度指标法对湿地松上松褐天牛的分布进行调查分析。结果表明:在湿地松上松褐天牛幼虫、成虫分布型都为聚集分布。松褐天牛蛀入孔、羽化孔分布与树高有关,在(5.1±2.3)m的树干上松褐天牛幼虫蛀入孔数最多,羽化数量最多的部位在(5.3±2.3)m。
The investigation and analysis of the distribution of Monochamus alternatus Hope on Pinus elliottii were conducted by the intensity index method. The results showed that the spatial pattern of the entrance hole and exit hole ofMonochamus alternatus Hope was classified as the assembling distribution on Pinus elliottii. There was certain relationship between tree heights and entrance holes or exit holes. The tree height （5.1 ＋2.3） m had the largest number of entrance holes bored by larvae. While the tree height （5.3＋2.3） m had the largest number of exit holes deposited by adults ofM. alternatus.
