| 摘 要： | 桃小食心虫卵的田间分布以聚集分布为主，而且具有密度依赖性，分布的基本成份是个体群。其Ｉｗａｏ回归式为ｍ－＝０．２６２７＋１．１３１５ｍ，Ｔａｙｌｏｒ回归式为ｌｏｇｓ２＝０．１９０２＋１．１１０１１ｏｇｍ。在分布型的基础上详细叙述了桃小食心虫卵的田间序贯抽样技术，并给出了田间抽样的最大最小抽样数量。

| Abstract: | The spatial distribution pattern of the peach fruit moth eggs(Carposina niponensis Wals) is mainly in an aggregation pattern with density-dependence in which the element units are colonies.Iwao's regression equation is m=2627 1.1315M,and the Taylor'S is logs2=0.1902+1.11011ogm.The Sequential Sampling technology relative to a critical density of the peach fruit moth borer eggs in orchard is described in details The maximum and minimum sampling numbers are also discussed. |
