| 摘 要： | 采用多个聚集度指标和回归分析法对枣大球蚧Eulecaniumgigantea及其主要天敌球蚧蓝绿跳小蜂Blastothrixsericae的空间分布格局进行研究。各聚集度指标均表明：枣大球蚧及其球蚧蓝绿跳小蜂在空间上的分布格局均是聚集分布；Taylor幂法则、1wao的回归分析法也表明：枣大球蚧及其球蚧蓝绿跳小蜂在空间上的分布格局也是聚集分布，且聚集强度随种群密度的升高而增加；这种分布形式的一致性，有力地提高了天敌对寄主的自然控制能力。表3参10

| Abstract: | The spatial distribution patterns of Eulecanium gigantea and its natural enemies Blastothrix sericae were determined, the equations of optimal sampling were formulated based on the regression models with mul- tiple aggregation indices. The result showed that spatial distribution pattern of Eulecanium gigantea and Blas- tothrix sericae belonged to aggregative distribution. Regression analysis of Iwao and Tayler also obtained a sim ilar conclusion, Eulecanium gigantea and Blastothrix sericae belonged to aggregative distribution and with the population density increasing, aggregation index increased. The coincidence in distribution effectively in- creased the control capacity of natural enemies on their hosts. Ch, 3 tab. 10 ref. ] |
