摘　　要：【目的】探明葡萄斑叶蝉成虫及若虫在田间的空间分布型及其抽样技术,为该虫的监测、预报及防控提供科学依据。【方法】采用聚集度指标法、Taylor幂函数法及Iwao回归法对葡萄斑叶蝉成虫及若虫的田间空间分布型及抽样技术进行研究,并根据Iwao提出的理论抽样数计算公式及序贯抽样理论公式,建立理论抽样模型及序贯抽样模型。【结果】聚集度指标法、Taylor幂函数法及Iwao回归法测定结果表明,葡萄斑叶蝉成虫及若虫在田间均呈聚集分布,分布的基本成分是个体群,种群个体间相互吸引,且密度越大,聚集度越高。5种抽样方法均可用于葡萄斑叶蝉成虫及若虫的抽样调查,其中Z字型法为葡萄斑叶蝉成虫最适调查方法,平行跳跃法为葡萄斑叶蝉若虫最适调查方法。葡萄斑叶蝉成虫及若虫在田间的理论抽样数学模型分别为:N=(9.920/m+0.972)/D2和N=(10.230/m+2.063)/D2。序贯模型分别为:T0(n)=nm0±t 2.582nm0+0.253m02和T0(n)=nm0±t 2.664nm0+0.537m02。【结论】葡萄斑叶蝉成虫及若虫在田间呈聚集分布;成虫田间抽样技术宜采用Z字型法,若虫宜采用平行跳跃法。[ Objective ]The spatial distribution patterns and sampling techniques of Erythroneura apicalis（Nawa） adults and nymphs was investigated, in order to provide scientific basis for monitoring, predicting and controlling it. [Method] The spatial distribution pattern and sampling techniques of E. apicalis（Nawa） were studied by aggregation index method, Taylor＇s power function method and Iwao＇s regression method. And the theoretical sampling model and sequential sam- piing models of E. apicalis（Nawa） adults and nymphs were established based on Iwao＇s theoretical sampling calculation for- mula and sequential sampling theoretical formula. [Result]The results showed E. apicalis（Nawa） adults and nymphs tend- ed to aggregated distribution in fields, and the individual colony was basic distribution component, individuals attracted each other. Therefore, the greater colony density was, the higher aggregation degree was. Five kinds of sampling methods could be used in sample survey of E. apicalis（Nawa） adults and nymphs, of which, the zigzag sampling method was optimal for aduhs of E. apicalis（Nawa）, and the parallel lines sampling method was optimal for nymphs of E. apicalis（Nawa）.The theoretical sampling models of E. apicalis（Nawa） adults and nymphs were as follows：N=（9.920/m＋0.972）/D^2,N=（10.230/m＋2.063）/D^2.Their sequential sampling models were as follows： T0（n）=nm0±√2.582nm0＋0.253m0^2,T0（n）=nm0±√2.664nm0＋0.537m0^2 .[Conclusion]The spatial pattern of E. apicalis（Nawa） adults and nymphs was aggregated distribution in fields, and the zigzag sampling method was optimal for E. apicalis （Nawa） adults, and the parallel lines sampling method was optimal for E. apicalis （Nawa） nymphs.
