Species and seasonal occurrences of Sencinae, Melolonthinae and Rutelinae chafers captured b by blacklight traps were investigated from 1989 to 1991 in Suwon and Chonju. Numbers of s species captured in Suwon and Chonju were 6 and 6 for Sericinae, 8 and 7 for Melolothinae, 7 a and 8 for Rutelinae, 21 and 21 in total, respectively. Species with more captures from both districts in each subfamily were Maladera orientalis of Sericinae, Holotrichia morosa and H. diomphalia of Melolonthinae, and Anomala corpulenta, and A. rufocuprea of Rutelinae. Adults of t the above five species were captured 1O~20 days earlier in Chonju than in Suwon. H. d diomphalia adults occurred mamly In odd years in Chonju, which is the same pattern as in S Suwon.

The white grubs were collected from ginseng field and fallow lands to examine their external morphology and species components. They were divided into 3 subfamilies, i.e., Melolonthinae, Rutellinae, and Sericinae by the shape of anal slit and/or presence of elevated lines in stridulating area of mandible. Eight species were identified by means of comparing the shape of anal slit, setal arrangement of decasternite, and frontoepicranial series of setae. Larvae of Holotrichia diomphalia and H. morosa were observed to damage ginseng root in field.
