Investigations on the spatial construction and distribution of M.karicola Matsumura and its natural enemies, C.kuwanae Silvestri, at different periods were conducted with geostatistics.The results indicated that the semivariogram of M. karicola Matsumura was described by spherical model from 18 April to 20 July and 23 September, showing an aggregated spatial arrangement. But in some special periods, for example, on 22 August and 25 October, the semivariogram of M.karicola Matsumura was depicted as linear models, showing random or even arrangement. As for C.kuwanae Silvestri, the models were all spherical ones from 18 April to 25 October, showing an aggregated spatial arrangement. The fuzzy neartude of observed semivariogram were high in different times, and the synchronous effects were obvious between M.karicola Matsumura with C.kuwanae Silvestri.
