| Abstract: | The spatial distribution statistical analysis method was used to study the spatial patterns of the 3rd instars of Melolontha hippocastani Fabricius. The results indicated that it was aggregative distribution in the soils of 0-10 cm in depth, with a group of individuals as a unit. It provides the basis for field investigation and control. |
