摘要
日本松干蚧Matsucoccus matsumurae是一种危害松林的重要外来入侵生物。为系统揭示外来入侵生物在森林生态系统中的发生及影响,从1982年至2008年,系统调查了浙江省临安市横畈林场日本松干蚧天敌生物的种类,跟踪了日本松干蚧及其天敌生物在自然生态系统和人工防控措施下的种群数量变化。结果发现:日本松干蚧在调查点有28种天敌生物;日本松干蚧呈现出波浪式消减特征;天敌生物种群结构与蚧虫消减存在密切的关系;人工防控措施可明显加快日本松干蚧和天敌生物稳定。结果揭示了松林生态系统调控日本松干蚧的自组织平衡特性。
Matsucoccus matsumurae （Kuwana.） is an important invasive pest in China. Population changes of M. matsumurae and its predatory enemies during the period from 1982 to 2008 have been investigated in Hengfan Forest Farm of Lin＇an City, Zhejiang Province. Twenty-eight species of the predatory enemies have been found. Results showed that the population of M. matsumurae exhibited a wave mode declination. The population constructions of the predatory enemies have a tight relation to this declination. The utilized pest control accelerates significantly the stability of the populations of M. matsumurae and its predatory enemies. It could be clarified that M. matsumurae processed its self-organization balance in the pine forest ecological system. [Ch, 2 fig. 1 tab. 11 ref. ]
