Geostatistic methods,omni semivariogram and punctural kriging,were applied to study the spatial pattern of dipausing larva of striped rice borer at a rice field.Combined with the probabilistic fitting and the biology of striped rice borer,the result showed that the pattern was formed by many homogeneous mass patches distributing in the field with the centre of 0.2～0.3m and the range of 1.8～2.0m.The vatues of the unsampled points were estimated by kriging estimation.
