Populations of beetles were surveyed by many hanging insects attractive traps at Utsunomiya University Forest in Shioya Town,Tochigi Prefecture in 1999. Beetles were collected by the traps once a week from April to October at three forest types; F.1:plantation of the Japanese cypress Chamaecyparis obtusa, F.2:plantation or natural growth of the Japanese redpine Pinus densiflora, F.3:broad-leaved forest. Dead beetles picked up at the traps in the three forest types were determined to species and counted in the laboratory. A total of 4,458 individuals of beetles from 239 species belonging to 46 families were recognized by the survey. In the three forest types numbers of species and individuals of longicorn beetles and scolytid beetles occupied more than any other beetle. Therefore,species richness and composition of the two families were compared on the three forest types. Species richness and species composition on forest types were different among scolytid beetles and longicorn beetles.
