| Abstract: | Spatial distribution patterns for larvae of Zeuzera multitrigt Moore were measured by means of several indexes of aggregation in Fuji Province. Frequency bistribution of larvae fits in with Poisson distribution quite well. The results of four sampling methods show that sampling of agon proved to be the best.By Iwao's methods the optimal sampling number of forest survey is analysed and calculated, the sequential analysis is also applied. |
