| 摘 要： | 采用概率分布x^2检验、5种聚集度指标及Taylor的幂指数法则与Iwao的m＊-m直线回归方程测定棉大卷叶螟幼虫在木槿上的空间分布型;利用Iwao理论模式确定棉大卷叶螟幼虫的理论抽样数及序贯抽样模式。结果表明,棉大卷叶螟幼虫在木槿上为聚集分布。

| Abstract: | The x2 test of probability distribution,5 kinds of aggregation indices,Taylor power law and m*-m linear regression equation of Iwao were used to determine the spatial distribution type of Sylepta derogata larvae on Hibiscus syriacus L..Using the theoretical model of Iwao,the theory sampling number and sequential sampling model were determined.The results showed that S.derogate larvae showed an aggregation distribution on H.syriacus. |
