| 摘 要： | 在大量取样的基础上，利用频次卡方检验法、若干聚集度指标法、计算和判断杨圆蚧及其寄生小蜂空间分布型。结果表明，杨圆蚧和寄生小蜂均属于聚集分布。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。

| Abstract: | Spacial distribution of poplar scale-insect Quadraspidiotus gigas(Thiem et Gerneck)and its chalcid parasites are calculated and determined by the methods of frequency distribution and some aggregation indexes based on a large number of samplings.The result shows that both host and parasites are all belong to aggregative distribution and it is just the coincidence in distribution that increases the control capacity of natural enemies on their host effectively. |
