| 摘 要： | 2003年11月和2004年6月,在松材线虫病典型发生区浙江省舟山市调查了马尾松上的钻蛀性害虫的种类和分布位置,分析了罹病木上的优势虫种的生态位宽度、生态位相似性、生态位重叠值.结果表明，在感染松材线虫病的松树上共发现5种昆虫,其中钻蛀类害虫4种,白蚁1种；在冬季和夏季生活于松树主干上的昆虫种类不尽相同，而且具有各自不同的生态位宽度,存在不同程度的生态位重叠,对空间和营养资源的利用有不同比例的相似性，依据其各自生物学特性和生活习性的不同达到竞争的平衡和共存.

| Abstract: | 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. |
