2003年11月和2004年6月，在松材线虫发生较典型的浙江省舟山市，对松材线虫在马尾松林内的发生情况及其空间分布进行了调查。在此基础上，计算了枯死乔木优势种的生态位宽度、生态位比例相似度和生态位重叠度。结果表明，感染松材线虫的马尾松有5种病虫害。其中4种为钻木甲虫，1种为白蚁。各寄主树种的生态位宽度、生态位相似性比例和生态位重叠度在冬季和夏季各有不同。因此，它们可以根据自己的生物学特性和生活习性实现竞争均衡和共存。
In November 2003 and June 2004, the boring insects and their spatial distribution within Pinus massoniana forest were investigated in Zhoushan City, East China＇s Zhejiang Province where Bursaphelenchus xylophilus happened typically. And then, the niche width, proportional similarity of niche and the niche overlap of dominant species of dying trees were computed. Results showed that 5 insect species infected and damaged Pinus massoniana which had been infected by Bursaphelenchus xylophilus. Among which four were wood boring beetles and one was termite. Species within host trees varied from winter to summer, and all of the species had their own niche width, proportional similarity of niche and niche overlap. So they can achieve competitive equilibrium and coexistence according to their biological characteristics and life habits.
