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.

We performed an experiment to confirm the possibility of wasabi culture using the wat­er of the Soyang River Dam in Chunchon and the ground water in Suwon. Water mineral content of Soyang River except for P was less than that of ground water of Suwon. Dis­solved oxgen and E C of Chunchon was proper to culture wasabi but E C and dissolved oxgen of Suwon was not suitable for that. Water temp. of Soyang river was very changable by month while that of the ground water in Suwon was kept constantly. In Soyang river of Chunchon the month that water temp. show $8{\sim}18^{\circ}C$, optimal growth temp., was May to Nov. and the month that water temp. show less than $6^{\circ}C$, growth limit temp., was $Jan.\;{\sim}\;Feb.$ of Chunchon. Rhizome weight of main stem in Chunchon and Suwon was 63g and 22g per plant and rate of maketable rhizome was each 80%, 0% by culture of 32 months to include raising see­dling period of 13 months. Dry matter partitioning ratio of petiole in Soyang river of Chunchon was the highest of all others but it was lowest of all others in ground water of Suwon. Rhizome weight of main stem in Chunchon was showed possitive correlation with plant height and fresh top weight and in Suwon it was showed possitive correlation with root weight and high possitive correlation with No. of total leaves and No. of tillers.

Maruca vitrata is a main insect pest against crops of Vigna species (V. angularis and V. radiata) and Sesbania sesban in Fabaceae, but the life cycle of the insect is unclear in Korea. In order to know over-wintering possibility, its stage of the insect, over-wintering entry season, and the first adult emergence season of the next year, we investigated over-wintering rates of the insect in outdoor conditions in Suwon ($37^{\circ}16^{\prime}N$ $126^{\circ}59^{\prime}E$ 35ASL). In all colonies which the rearing for larvae, pupae and eggs started after mid-September, adults did not emerge within the year, and all insects died before next June. In several trials for over-wintering of larvae and pupae in soil, all insects died, too. Larvae stored during specified periods at low temperatures (10 and $13^{\circ}C$) did not emerge. From the results, it was postulated that M. vitrata does not have an adaptability to temperature below zero, and cannot over-winter in Suwon area.

A total of 16 varieties from Korea and Indonesia were tested at Suwon, Korea (126$^{\circ}$19'E, 37$^{\circ}$16'N and 37m above sea level) and Bali, Indonesia (115$^{\circ}$ 14'E, 8$^{\circ}$42'S and 10m above sea level). Japonica-type varieties showed pre-matured heading at Bali, tropical zone, while Bulu varieties showed no heading at Suwon, temperate zone. The varieties of Indica-type and Ind./Jap. showed faster heading in tropical zone than in temperate zone. Dry matter of the varieties weighed more difference among varietal groups in tropical than in temperate area, while plant height responsed differently depending on variety and test region.

The growth of Pinus Thunbergii in the four areas was compared with each other, and the results obtained are as follows ; 1. The diameter growth in HAP-CHUN area was found the best, and that of WOOI-SAN, CHE-JU, and SUWON areas was followed in order. 2. The height growth was found the best in WOOI-SAN area, and followed SUWON, HAP-CHUN, and CHE-JU areas in order. 3. The volume growth was found the best in HAP-CHUN area, followed next in order were : WOOL-SAN CHE-JU, and SUWON. 4. Based on the above-mentioned results, it was concluded that the growth of Pinus Thunbergii in inland areas was better than that in islands or coastal areas. This is against the common understanding that Pinus Thunbergii species grow better in coastal areas.

1. 추기 적엽방법에서는 염병 따기가 눈 마름병 발생이 적었다. 2. 추기 벌채는 강벌채 일수록 눈 마름병 발생이많다. 3. 눈 마름병균의 뽕나무 가지 침입시기는 수원지방의 경우 8월중순부터 9월하순경이였다. 4. 추기 조상벌채후 11월이후 재벌채 하면 눈 마름병을 억제 할수 있다.

도시화와 공업화의 부산물인 오염부하량과 그 종류 증가로 우리의 식수원은 날로 위협받고 있으며, 수질 문제가 국민생활의 질 향상과 산업성장의 발목을 조일 수도 있게 되었다. 여기에서 수자원 관리현황과 그 해결 방안을 생각해 보고, 도서지방등 근본적으로 수원확보에 문제가 있는 지역에 대한 대체수원 대책으로 수자원공사에서 추진하고 있는 막처리에 의한 해수 담수화 추진계획도 간단히 소개하고자 한다.
