| Abstract: | The horizontal and vertical distribution of over wintering pupae of Micromelalopha troglodyta (Graeser) in soil was surveyed and analyzed. The results indicated that the pupae were in the spatial pattern of aggregation distribution, with a group of individuals as a unit; most of them were distributed in ground litter under shadowing area of tree crown, within a circular area of radius 120～160 cm from host stem. |
| Keywords: | Micromelalopha troglodyta over wintering pupae spatial distribution pattern |
