| Abstract: | 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. |
