| 摘 要： | 对烟田蓼蓝齿胫叶甲幼虫的空间分布型测定结果表明:聚集度指标测定为聚集分布;频次分布检验为负二项分布;Iwao的*m-m回归模型为*m=0.1716+1.4552m,说明属于具有公共K值的负二项分布。本文根据聚集度均数(λ)的测定结果,分析了聚集原因和最适合的抽样数模型。

| Abstract: | Spatial distribution of Gastrophysa atrocyanea (Motschulsky) larvae, a herbivorous bettle attacking Polygonaceae in tobacco field is determined. The results show that it displays as the negative binomial distribution by determination of frequency distribution and fits to the pattern of aggregation by the test of distribution pattern indices. The linear regression equation of Iwao's *m-m can be described as *m=0.1716+1.4552m, so it fits to the negative binomial distribution with the public K value. The reason for the aggregation is analyzed according to estimation by mean aggregation (λ). The theoretical sampling number model is also built up in the present paper. |
