摘要
应用空间分布参数、Iwao回归法和Zaylor幂法进行分析表明，女贞瓢跳甲幼虫在大茉女贞上呈负二项分布，分布的基奉成分为个体群，且个体群为随机分布。通过测定不同受害程度的大叶女贞上女贞瓢姚甲幼虫的聚集均数又可知，该虫的聚集由成虫的产卵习性和环境异质性共同引起。在该虫空间格局研究的基础上，建立了Willson-Iwao复合序贯抽样模型和Kuno—Iwao复合序贯抽样模型。
The spatial distribution parameters, parameters of Iwao model and Taylor＇s power law were used to analyze the spatial pattern of the lavae of Argopistes tsekooni Chen in glossy privet （Ligustrun lucidum Ait）. The results showed that its spatial pattern was negative binomial distribution, with colony as its basis component and its colony distribution was random. The aggregative means of the different damaged glossy privet indicated that its aggregative reasons were related to the oviposited habit of the adults and environmental factor. Based on the data of the spatial distribution, two compound sequential models of Willson-lwao and Kuno-Iwao were presented.
