| Abstract: | Two regression models and four indices of aggregation were used toexamine the spatial distribution pattern of Rhagoletis batava obsecerlosa larvae, theresult indicated that the distrihution of R. batava obseceriosa larvne was inaggregate pattern and in compliance with negative binomial in harrned Hippophaeybamuoides forest. The number of theoretic sampling and plan of sequentlal sam- pling were established by m -m rogression method. |
