Self-organization balance of Matsucoccus matsumurae in the pine forest ecological system.
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.
