Abstract: In the winter of 1991 and the spring of 1992, 388 individuals of soil beetles were collected in Chi-nese chestnut forests on hills of southern Anhui province.They belong to 23 families, 27 generaand 29 species, among which, the larvae are under 13 families and the adults are under 17 fami-lies.The average density is 609·m^-3.The individual number of larvae is 2.59 times as that ofadults′,The dominant genera are Melolonthidae (L ),Curculionidae(L)and Elateridae(L).Onslopes with old trees and better drainage,there are more genera of soil beetle,the nurnber ofwhich is larger on western and eastern slopes than on northern slope.The individual number andits density of soil beetles are also larger in the valley and on the eastern slope.There are many soilbeetles within a distance of 1.3-1.5m from tree rcots, which decrease with increasing distance.It is worth to notice that the difference in number of soil beetle is bigger between two neighboringsampling plots than between the sampling plots of different areas, which was little reported in thepast.
