摘　　要：【目的】研究苹果小吉丁优势天敌苹果小吉丁刻柄茧蜂空间分布型和抽样技术。【方法】应用多个聚集度指标和Iwao,Talor回归分析法对新疆伊犁河谷地区野果林苹果小吉丁刻柄茧蜂幼虫空间分布型进行研究。【结果】苹果小吉丁刻柄茧蜂幼虫空间分布型聚集分布,最适理论抽样数公式为N=t2/D2(1.858 01/-X+0.20789)。【结论】通过对苹果小吉丁刻柄茧蜂幼虫空间分布型研究,为今后研究苹果小吉丁刻柄茧蜂种群动态及保护利用提供理论依据。【Objective】The purpose of this study is about the spatial distribution pattern and sampling technique of Atanycolus sp.larvae. 【Method】Spatial distribution patterns of Agrilus mali Matsumura and Atanycolus sp.Larvae in Ili river valley of Xinjiang were studied by several aggregation indices and regression analysis methods of Iwao and Tayler.【Result】Spatial distribution pattern of Atanycolus sp.Larvae was aggregation distribution,and the optimum theoretical sampling model was N=t2/D2（1.858 01/＋0.207 89）.【Conclusion】The study of patial distribution pattern of Atanycolus sp.larva can provide theoretical baisis for future investigating its population trends,protection and utilization.
