摘　　要：近年来绿盲蝽Apolygus lucorum已经逐渐发展成为果树上的重要害虫之一,对其越冬卵在果树上的空间分布型进行探究具有重要意义。本研究利用6种聚集度指标、Iwao回归方程和Taylor幂法则分析了苹果园中绿盲蝽越冬卵的空间分布型,同时对苹果园绿盲蝽越冬卵聚集的原因和最适理论抽样数进行了分析与计算。结果显示,绿盲蝽越冬卵在苹果园呈聚集分布,并且随着越冬卵密度的增加,分布越聚集。绿盲蝽越冬卵的种群聚集是由其生活习性与周围环境共同引起的。运用绿盲蝽越冬卵空间分布型参数,建立Iwao理论抽样数模型,从而明确不同密度下绿盲蝽越冬卵的最适理论抽样数,为今后绿盲蝽越冬卵在苹果园内密度的准确调查和种群密度的预测提供了理论依据。Apolygus lucorum has become one of the most harmful pests on fruit trees.It is of great significance to investigate the spatial distribution pattern of its overwintering eggs on fruit trees.This paper used the six aggregation indexes,Iwao’s regression equation and Taylor power rule to analyze the spatial distribution pattern of the overwintering eggs of A.lucorum in an apple orchard.In addition,the reasons for the aggregation of the overwintering eggs were analyzed and the theoretical sampling number were calculated.The results showed that the spatial distribution pattern of the overwintering eggs in the apple orchard was aggregation distribution,and the higher the density of overwintering eggs,the more aggregative the distribution.The overwintering eggs aggregation was mainly caused by bionomics and effect of environment.The Iwao theoretical sampling number model was established by using the spatial distribution parameters of the overwintering eggs which could determine the theoretical sampling number of the overwintering eggs under different egg densities,and provide a theoretical basis for the accurate prediction of the density of A.lucorum overwintering eggs in apple orchards in the future.The results provided a reference for the prediction and control of A.lucorum in early spring apple orchards.
