The community of xylophagous beetles belonging to Cerambycidae, Curculionidae and Scolytinae in Korean white pine, Pinus koraiensis Siebold & Zuccarini, forests was surveyed using Malaise traps in 2007. A total of 1,615 xylophagous beetles were collected, including 184 cerambycids from 15 species, 185 curculionids from 17 species, and 1,246 scolytid beetles from 6 species, of which the dominant species was the ambrosia beetle Xyleborus mutilatus Blandford. Ranked by order of population size, the wood-boring and bark beetle community in Korean white pine showed high dominance by one species of Scolytinae, suggesting the community had low biological diversity. Thinning in Korean white pine forests influenced on the abundance of bark and ambrosia beetles, whose populations in particular stands increased 1 year after thinning, and then decreased the following year.

전국어디서나 쉽게 볼 수 있는 개나리는 봄이 오면 노란 꽃망울을 피워 우리의 가슴을 설레게 하는 봄의 전령이다. 노란 꽃은 병아리와 비유되어 어린 아이의 귀엽고 깜찍한 모습과 비교되는 우리와 매우 친숙한 나무이다. 전국의 어디서나 음지, 양지, 모두에서 잘 자라며 추위와 건조에도 매우 강하고, 공해와 염기에도 강하여 울타리 조성용, 조경수, 관상수 등으로 널리 보급되어 우리의 생활주변에 자리 잡은 나무이다. 개나리나무에 개나리잎벌, 좀검정잎벌, 식나무깍지벌레 등이 기생하여 피해를 주고 있어 이들에 대한 간략한 생태 및 방제법을 기술하고자 한다.

Beetles belonging to the families Scolytidae, Platypodidae, Bostrichidae, and Lyctidae intercepted from imported timbers at Busan port were investigated from March 1 to November 30 in 2000. In addition, hosts imported country were examined. A total of 52 species of within 23 genera was intercepted from nineteen species of timbers or logs from fifteen countries. In Scolytidae, 35 species of 16 genera in three subfamilies were identified 12 species in Xyleborus, 6 species in Ips, 3 species in Trypodendron, 2 species in Arixyleborus, and 12 species of all different genera including Alinphagous. Scolytidae were intercepted from 16 species of timbers in 13 genera imported from 11 countries. The highest beetles were intercepted from Malaysian lauan. In Platypodidae, 9 species of one genus (Platypus) were intercepted from 6 species of timbers in 4 genera imported from 6 countries including Australia. The highest numbers were intercepted from Malysian lauan. In Bostrychidae, 5 species of 4 genera in two subfamilies were intercepted from 6 species of timbers in 4 genera imported from four countries. In Lyctidae, Trogoxylon sp., Minthea sp., and Minthea rugicollis were intercepted from 3 species of timbers in 2 genera imported from 3 countries.

경상북도 낙동상 상류부에 위치한 하천변 식물군락에 대해 식물사회적 조사를 하였다. 그 결과 아래처럼 10군강에 속하는 30군락단위와 상급단위 미결정의 1군락단위를 식별하였다. 특히, 과거에 인위적 영향을 반영하여 쑥군강에 속하는 군집 군락이 가장 많이 출현하였다. A. 관목식물군락-A-1나도버들군장, 버드나무군단: 버드나무-왕버들군집, 버드나무군집, 시무나무군집, 갯버들군집, 눈갯버들군집, 선버들군집, A-2 찔레꽃 군강: 국수나무군락, 구기자나무군락: A-3 상급단위 미결정의 군락: 누리장나무군락; B, 초본식물군락 B-1 가래군강: 노랑어리연꽃군집, 마름군락, B-2 좀개구리밥군강: 좀 개구리밥-개구리밥군랍, B-3 가막사리군강: 고마리군집, 미꾸라지낚시-여뀌군집, 개기장-여뀌군집, B-4 갈대군강; 창포군집, 갈풀-미나리군집, 달뿌리풀군집, 물억새군집, 갈대군락, B-5 쑥군강:물쑥군집, 쑥군락, 물봉선군락, 왕고들빼기-환삼덩굴군집, 칡-환삼덩굴군집, 수크려군랑, B-6 명아주군강: 물피군락, 바랭이군란, 큰개여뀌군락, B-7 억새군강: 억새군락, B-8 질경이군강: 비노리-질경이군락, 이들 식생단위는 거의가 일본의 것과 공통하고 있어 한국에 고유한 하천변 식생은 매우 드물다는 사실을 나타내었다. 한편 하천에는 고유한 군강의 군집, 군락은 하류에서 상류로 감에 따라 양적으로 증가 하였으마, 귀화식물의 수는 그 반대였다. 또, 각 군락과 환경과의 관계, 하천변 식생의 복원생태 및 자연보호 등에 관해 상세히 논하였다.

A survey of syntaxa of vegetation of evergreen broad-leaved forests in Korea, class Camellietea japonicae is presented. 399 releve's were arranged two phytosociological tables, each representing an alliance. A synoptic table comprising all alliances is presented. The vegetation of evergreen broad-leaved forests is divided into three alliances including twelve new associations: (1) Querco - Castanopsion all. nov., split into four associations, Castanopsietum sieboldii, Quercetum acutae, Quercetum myrsinaefoliae and Litseetum japonicae; (2) Machilo-Camellion all. nov., separate into ten associations, Machiletum thunbergii, Pittosporetum tobirae, Aucubetum japonicae, Neolitsetum sericeae, Euryetum emarginatae, Elaeagnetum macrophyllae, Camellietum japonicae, Theo-Camellietom japonicae, Raphiolepietum umbellatae and Daphniphylletum macropodae; (3) Dendropanaco-Castanopsion sieboldii including one association, Hosto minoris-Castanopsietum sieboldii. The alliances are floristically and ecologically characterized and their distribution in Korea shown on the map.

Biological control of forest insect pests, Agelastica coeruleci, Meganola n~elancholia,a nd Glyphodes perspectalis, turfgrass insect pest, Blitoperfhu orientr~lis,v egetable insect pests, Plutella xylostella and Agrotis segetun~ with entomopathogenic fungus, Beciuveria hassinna GY 1 - 17 isolated from rice paddy of Yangsan in the southern part of Korea were investigated. Mortalities of A. coeruleu and P. ~ylo.~rellluar vae were 100% at the rate of 7.0 and 2.0 x 107conidia/ml after 7 and 5 days and those of M. melancholia were 66.7 - 100% at the rate of 0.03875-3.1 X 107conidia/ml. However, G. perspectulis was not affected at the rate of 2.0 x lo7 to X I04conidia/ml. And mortalites of B. orientcilis and A. segetum larvae were 46.7% at 3.7 x 107conidia/ml and 63.3% at 2.5 X 107conidia/ml.

To clarify some ambiguous diagnostic characters of Callicarpa japonica Thunb. and Callicarpa dichotoma (Lour.) K. Koch in Korea (Verbenaceae), the external morphology and micromorphology (leaf, anther, pollen, fruit, in particular endocarp surface and structure) of two taxa are studied and described in detail. It is confirmed that the following characteristics (e.g., the stem outline in a cross-section, the bud shape and length, the corolla tube length and the lobe length, the pattern of the anther dehiscence and length, and the endocarp morphology) are useful for distinguishing these two taxa. In particular, following three characteristics are most useful for an identification: (1) the corolla tube length of C. japonica (2.5-4.6 mm) is longer than that of C. dichotoma (0.7-1.0 mm); (2) the anther is dehiscing by an apical pore at the anthesis of C. japonica, while it is opening by a long fissure from the apex to the base in C. dichotoma; and (3) the edge of the endocarp (lateral view) in C. japonica is concave, while in C. dichotoma it is shown to be flat. On the other hand, the teeth state on the leaf margin and the position of inflorescence are not good diagnostic characteristics for identification. Additionally, the keys for all known Callicarpa taxa in Korea are provided.

Five species, Hypothenemus californicus, Coccotrypes carpophagus, Othotomicus angulatus, Tomicus brevipilosus and Xyleborus seriatus were recognized firstly from Korea. Two species of them, H. californicus and C. carpophagus were preserved at Life Science Museum of Brigham Young university in U.S.A. X. seriatus intercepted at Kobe in Japan from imported yew log which had shipped at Nampo in North Korea was sent by Dr. F. G. Browne in England. Thirteen recorded species were also examined in this study.

안개나무 목질부의 열수추출물을 사용하여 한지를 염색하였다. 안개나무 목질부의 추출물을 동결건조하여 만든 염료 분말을 사용하여 제조한 0.0002%(wt) 농도의 염액은 198 nm에서 0.39의 흡광도를 278 nm 에서 0.10의 흡광도를 가지는 자외가시광선 흡수 피크를 나타내었으며 무매염으로도 한지에 염색이 잘 되었다. 염색된 한지는 황색 계열의 색을 나타내었으며, 명반 매염을 하면 $a^*$ 값과 $b^*$ 값이 동시에 증가하여 주황색을 띠는 것을 알 수 있고, 초산동 매염을 하면 $a^*$ 값이 증가하지만 $b^*$ 값이 감소하여 적색을 좀 더 많이 띠게 되었다. 염화철 매염을 하면 $b^*$ 값만 크게 감소하여 녹색계열의 색을 나타내었다. 닥섬유에 염색시 온도가 증가함에 따라서 염착량은 감소하는 경향을 보였고, 양이온화 섬유를 사용하면 염착량이 크게 향상되나, $a^*$값이 더 크게 증가하여 색상이 적황색으로 변하였다. 표면 전하밀도와 염착량은 정비례의 관계를 나타내었으며, 양이온화 정도가 높아질수록 제조한 색한지의 광견뢰도는 악화되었다.
