The soybean varieties the bean bug preferred the least were Kwangankong, Namhaekong, Sunamkong, Sorogkong, and Anpyeongkong, and next to them was Pungsannamulkong, among 25 varieties examined. Myongjunamulkong and Eunhakong supported a good growth of the bug as the daily gains of weight of 3rd instar nymphs were 14,9 and 13.9 mg, respectively. On the other hand the bug on Punsannamulkong gained weight daily as little as 10.1 mg. On Pungsannamulkong the nymphal development of the bean bug took $24.5{pm}2.1$ days, about three days longer than those on Myunjunamulkong and Eunhakong. The survival of the bean bug on Punsannamulkong was 83%, slightly lower than those on Myunjunarnulkong and Eunhakong. It seemed evident that Pungsannamulkong have a non-preference type resistance to the bean bug.
