摘要
应用6种聚集度指标、Taylor和Iwao回归分析法对砂生槐种子蜂幼虫的空间分布格局进行了分析,得出砂生槐种子蜂幼虫的空间分布型为聚集分布,田间调查抽样方法为分行取样法,并得出田间幼虫不同密度时的理论抽样数。
The spatial distribution pattern of the larvae of Bruchophagus sp. on Sophora moorcrofiiana （ Benth.） Baker was studied by 6 aggregation indices and regression analysis methods of Iwao and Tayler. The results showed that the spatial distribution pattern of the larvae was the aggregation distribution. The suitable sampling method was the row sampling in the field. The theoretic sampling quantity was also discussed in this paper.
