| 摘 要： | 昆虫的空间分布型是昆虫种群属性之一,也是昆虫生态学的内容。探明昆虫的空间分布型,可以深入了解其生物学特性,通过种群分布的信息,揭示种群的空间结构及分布形式,为确定抽样技术、取样数量和分析提供依据,对生态学理论和生产上都有重要意义。为探索松突圆蚧Hemiberlesia pitysophila Takagi分布特点,我们于1987～1988年,对广东省惠

| Abstract: | seven methods were used to test the spatial distributin patterns of population of Hemiberlesia pitysophila Takagi in the young plantations of Finns massoniana. The results showed that the distribution patterns of H. Pitysophila belongs to an aggregated distrbution. Variance analyses were used to statistics the insect population on different position and stratification levels of the tree crown. The results showed there was no significant difference in the test. |
