| 摘 要： | 连续6年的林间定点定期观察表明,松突圆蚧侵入马尾松林后,由于缺乏有效天敌的控制,其种群将迅速增殖膨胀。经过3～4年的急剧增殖后,则迅速走向衰退,而导致松突圆蚧种群衰退的首要因素是受害的马尾松正常生长的崩溃。

| Abstract: | Hemiberlesia Pitysophila Takagi was accidentally introduced into Guangdong, China at the beginning of 1980's, and soon became a serious pest of Pinus massoniana. The population dynamics of H. pitysophilu was discussed in this article. After regular observations were made for 6 years, it showed that the population of the pest was expanded rapidly in the first 3-4 years in case it colonized in the pine tree forests, for lack of the effective control of the natrual enemies, and then the population declined and collapsed quickly due to the weakness of the damaged pine tree. |
