| 摘 要： | 采用Taylor幂法则、lwao线性回归及各种聚集度指标分析了矮化密植枣园第一代枣瘿蚊幼虫的空间分布型,结果表明：枣瘿蚊第一代幼虫在田间符合聚集分布,这可能是由其自身的行为习性引起的。通过几种田间抽样方法的比较确定最佳方法为棋盘式抽样法。同时采用lwao方法求出了最适抽样数。

| Abstract: | In order to understand ecological habits of F_1 Larvae Contarinia sp.and develop sampling methods,the various indices of aggregated degree and the regression of straight line ( m~*-m) and Taylor method were studied.The results in- dicated that their distribution belonged to aggregated pattern in the Short-stalked and Close-planting Jujube yards and this pattern was causes by their own.The sampling methods chess manual was most suitable.The optimum sampling number was obtained by Iwao's method. |
