Two species of Syrrhopodon [S. japonicus (Besch.) Broth. and S. armatus Mitt.] were newly recorded from Jeju Island. S. japonicus was found on a rock covered with fine soil on the Che-oreum Volcano. This species is clearly distinguished from other species of the genus by its plants to 40 mm long, leaves bordered with several rows of short cells, and the margins at the leaf shoulders being regularly serrate. Syrrhopodon armatus was found on tree bark on Seopseom islet. It differs morphologically from other species of the genus in terms of its plant at 10 mm long, leaves bordered with one to several rows of linear and hyaline cells, leaves with spinous teeth at the shoulders. We propose new Korean names for these two species: 'Seon-o-reum-i-kki' and 'Jag-eun-seon-o-reum-i-kki,' respectively, which are based on their plant size and their first locations in Korea.

Seasonal occurrence and visiting flowers species of overwintered bumblebee queens were investigated during the spring season of 2000. A total of 1,277 overwintered bumblebee queens were collected, consisting of seven species of Bombus and one species of Psithyrus. The dominant species were Bombus ardens Smith and Bombus ignitus Smith. The heydays of their occuring season were the early April for B. ardens and the second half of the May for B. ignitus. B. ignitus was mainly collected on Prunus yedoensis Matsumura and Corydalis speciosa Min, and B. ardens on the Rhodldendron mucronulatum Turcz and Prunus yedoensis.

We report previously unrecognized flowering plants of Lao PDR found during a botanical survey of Lao PDR in 2015-2016. We found Phyllagathis tuberosa (C. Hansen) Cellinese & S. S. Renner (Melastomataceae) and Tolypanthus pustulatus Barlow (Loranthaceae) in the Phou Khao Khouay National Biodiversity Conservation Area (PKKNBCA), previously only known from type localities in Thailand. This is the first report of Phyllagathis tuberosa and the genus Tolypanthus in the Lao PDR. We also found Lonicera bournei Hemsl. (Caprifoliaceae) in the proposed Phosabous National Protected Area (PNPA) of Xiangkhoang, neglected with regard to the flora of Laos since its initial report in early 20th century. The current report will augment our understanding of the floristic relationships among SE Asian countries and will help elucidate the biodiversity of Lao PDR.

Phytophagous insects associated with Dicotyledoneae weeds and host specificities in the field populations were investigated for the survey of biological control agents of weeds in Korea. Fifty four weed species in 39 genera were collected during the survey. The most insects were collected from Polygonales by 24 species in 22 genera and followed by Urticales and Centrospermales by 17 species of 17 genera. The insects collected in the other weed orders were ranged from 1 to 12 species. Out of 17 insect species collected in Urticales, Baris sp. damaged the leaves of Hamulus japonicus in Cannabinaceae as scattered holeshape and showed host specificity. In Polygonaceae, Rumex japonicus and R. crispus were severely damaged by Aphis rumicis and Gastrophysa atrocyanea. G. atrocyanea leaf beetle had host specificity on R. japonicus and ate all the leaves except veins. The leaf beetle, Lypesthes japonicus was a potential biological control agent by feeding leaves of Persicaria spp .. And Lixus spp. were also often collected from Persicaria spp .. Liothrips vaneeckei was first collected from weed, P. modosa. P. senticosa was damaged by unidentified geometrid moth larvae and P. perfoiliata by Miarus atricolor snout beetle. Cassida piperata damaged leaves of Chenopodium album of Centrospermales and showed host specificity. In a soybean field, C. album and Amaranthus mangostanus were severely damaged by Spodoptera litura larvae which were eating soybean leaves. This phenomenon indicates that the presence of weed in cultivated land influences the outbreak of insect pests. Altica oleracea leaf beetle was frequently collected from Oenothera spp. of Onagraceae in Myrtales. Aphis gossyphi was outbroken on Solanum nigrum and Phylliodes brettinghami leaf beetle was first recorded on the same plant. Leaf beetles, Longitarsus scutellais and Hemipyxis plagioderoides were first collected from Plantago asiatica of Plantaginaceae in Plantaginales. They showed host specificities in the fields. The hemipterans were collected from many weeds during the survey and their roles on weeds should be investigated. A tractomorpha bedeli was also collected from many kinds of weeds in forest areas.

Four types of spore trap (Kim's original, improved Kim's original, Yoshino's original and mixed type of Kim's and Yoshino's original) were evaluated for their efficacy to "estimate the amount of spores released from leaf blast lesions under the natural conditions. It was found that all four types had one or two defects in allowance for adequate sporulation/release, spore catch or spore counting. Thus, an improved type of spore trap was devised considering that it could cover the defects mentioned above. As a result, newly developed spore trap was quite satisfactory in above mentioned aspects and it could be used for pursuit of spore release phase under the natural conditions.

필자는 1960년 이후 몇 차례에 걸쳐 경기 가평 명지산을 중심으로 그 부근의 곤충류를 채집한 바 있다. <1960년 5월 , 다시 동년 8월과 9월 , 1961년 5월과 8월> 이곳은 위 37도 90분, 동경 127 도 40분에 위치한 곳인데 38도선 접경지대로 해발 1, 267m의 최고봉을 중심으로 하여 남향 동서로 1250m , 1017m , 994m의 연봉이 U자형으로 둘러싼 일연의 산지로 식물상이 대단히 풍부한 곳이다. 종래 이곳의 곤충에 대하여는 조사된 바 없기에 기간에 채집한 것을 보고하여 기학들의 후일의 연구에 차하고져 한다.

This study introduces the bryological history and literature of the Korean Peninsula. The French missionary Urban Faurie was the first person to collect Korean bryophytes at the beginning of the 20th century. Most of his bryophyte collections from Korea were studied and recorded by Jules Cardot (for mosses) and by Franz Stephani (for liverworts). Japanese studies of Korean bryophytes were described in chronological order. Hong Won Shic and Choe Du Mun carried out an inventory and flora research on bryophytes in South Korea. The most recent bryological studies of North Korea are also reviewed here as a reference.
