| 摘 要： | 应用6种分布型指数法分析判定了槐豆木虱Cyamophila willieti(Wu)]若虫在国槐(Sophora japonicaLinnaeus)上的空间分布型,利用Taylor(1961)幂法则和Iwao(1971)回归方程分析聚集原因,结果表明,槐豆木虱若虫在国槐上呈聚集分布,公共kc值为5.159 0,且符合负二项分布;其种群聚集原因是由昆虫本身行为习性所致。在此基础上,采用Iwao的方法确定了槐豆木虱若虫的田间理论抽样数和序贯抽样表。 |

| Abstract: | The spatial distribution patterns of Cyamophila willieti nymphs in Sophora japonica garden were studied using six spatial distribution pattern analysis methods,and the assembling reasons were analyzed with Taylor power law and Iwao regression equation.The results indicated that the aggregated distribution of the C.willieti nymphs in field fitted the negative binomial series(kc=5.159 0);the reason for aggregation might be due to the insect natural habit.Based on the distribution pattern,the theoretical sampling number and sequential sampling table were calculated by Iwao’s method. |
