  • The ambrosia beetle, Platypus koryoensis, is a serious pest of oak trees in Korea. In this study we investigated filamentous fungi present in the body of the beetle. Fourteen genera of filamentous fungi belonging to Ascomycota and Basidiomycota were isolated. Among the isolated fungi, some were able to produce wood degrading enzymes. This is first report of fungi associated with P. koryoensis.

  • 경상남도 진주와 하동지역의 산초나무 재배단지에서 잎녹병에 의한 피해가 매년 지속적으로 발생하고 있다. 산초나무 잎에 형성된 여름포자세대의 녹포자세대 기주를 밝히고 녹병균을 동정하기 위하여 본 병해의 발생지 주변 곰솔에서 채집된 녹포자를 산초나무에 인공접종하였다. 그 결과 산초나무에서 성공적으로 여름포자가 형성되어 이 녹병균은 녹포자세대를 곰솔에서, 여름포자 및 겨울포자세대를 산초나무에서 형성하는 장세대형 생활사를 갖는 C. xanthoxyli로 동정하였다. 대부분의 형태적 형질은 기존 기록과 일치하였으나 녹포자와 여름포자의 표면돌기 수에는 차이가 있었다. 곰솔과 산초나무에서 채집된 C. xanthoxyli의 건조표본을 이용하여 녹포자세대 및 여름포자세대의 형태학적 특징을 기술하였다. 경남 진주와 하동지역에서 조사된 산초나무에서의 최초 병발생시기는 6월 하순${\sim}$7월 초순이었으며 8월 중의 이병엽율은 17.8%${\sim}$58.7%이었다.

  • Plants planted in the green-roofed areas in Busan and Jinju were surveyed. The woody plants investigated in this study were classified into 52 families and 156 species, and the herbaceous plants were classified into 30 families and 97 species. Woody plants mainly planted were Rhododendron yedoense var. poukhanense, R. indicum, C. kousa, P. mume, and E. alatus. However, Pinus spp. were planted in all areas. The main herbaceous species planted were Sedum kamtschaticum, S. takesimense, S. middendorffianum, T. quinquecostatus var. japonica, and A. spathulifolius Maxim. According to surveying the distribution of woody plant pests, they could be classified into six orders, 24 families, and 46 species that usually appeared from April to October but especially between June and September. We investigated 39 insect species in relation to pest damage to leaves, 21 insect species in relation to that of branches, and 39 insect species in relation to that of stems of woody plants.

  • 173종 국내산 식물체의 메탄올 추출물을 대상으로 5 종의 주요 농업해충에 대해 살충 및 살비 효과를 조사한 결과 식물의 종류 및 채집부위에 따라 커다란 차이를 보였다. 173종 420 샘플을 5,000ppm 농도로 처리하였을 때 벼멸구에 강한 살충 효과를 나타낸 식물체는 초피나무 수피, 편백나무 잎과 참가시나무 잎이었다. 배추좀나방 유충에 대해서는 굴피나무 목부, 나도밤나무 수피, 회화나무 잎, 초피나무 수피, 그리고 해송 목부 추출물이 강한 살충활성을 나타내었고 회화나무 잎 및 초피 수피 추출물은 담배거세미나방유충에 강한 살충활성을 나타내었다. 점박이응애에 대해 강한 살충활성을 나타낸 식물체는 소사나무 잎, 벽오동 수피, 보리밥나무 잎, 두릅나무 잎, 층층나무 수피, 그리고 편백 잎이었다. 특히 초피나무 수피 추출물은 여러 해충에 대하여 강한 살충효과를 나타내어 해충 방제에 크게 이용할 수 있을 것으로 기대되었다.

  • Rhizina undulata, the causal agent of Rhizina root rot, is a soil-borne fungus occurring on coniferous trees. The destruction of coastal forests caused by R. undulata infection has been mainly associated with bonfires at camping sites. However, Rhizina root rot was observed in the western coastal forests without fire. It was hypothesized that Rhizina root rot in this area might be closely related to the soil salinity, which can facilitate the growth and survival of R. undulata. So, the variation in sodium chloride (NaCl) resistance among isolates of Rhizina undulata was compared using liquid media containing different concentrations of NaCl ranging from 0 mM to 300 mM. Our results showed that, albeit of no growth at a higher concentration of NaCl (300 mM), most of R. undulata isolates were capable of germinating and grew at up to 100 mM, indicating that NaCl resistance varies among R. undulata isolates. It was further found that isolates from coastal areas seemed to be more tolerant to NaCl than those further away the coast. We demonstrated that R. undulata could be possible to survive in coastal areas, but was lower NaCl tolerance than other fungi.

  • The ambrosia beetle, Platypus koryoensis, is an economically important pest affecting oak trees in Korea. Candida kashinagacola was isolated from galleries of the beetle in oak wood and identified by analyses of morphology, physiological properties, and nucleotide sequence of the large subunit ribosomal DNA. This is the first report on Candida species associated with oak wilt disease vectored by the ambrosia beetle, Platypus koryoensis, in Korea.

  • Biological control of turfgrass insect pest Blitopertha orientalis, forest insect pests, Agelastica coerulea, Meganola melancholia, and Glyphodes perspectalis,vegetable insect pests, Plutella xylostella and Agrotis segetum were conducted with entonopathogenic fungus, Metarhizium anisopliae J-22 isolated from black pine forest soil in Cheju province. Mortality of B. orientalis larvae was 53.3% at the rate of 3.4 $\times$ 1O 7 conidia /ml. A. coerulea and M melancholia larvae showed 100% mortalities at 9.6 $\times$ 106 conidia /ml and 2.7 $\times$ 10 7 conidia /ml as well. However, G. perspectalis larvae were not dead even at 4$\times$ 1O 7 conidia /ml. On the other hand, M anisopliae J-22 was effective against P. xylostella larvae showing 100% mortality at 4 $\times$ 10 7 conidia /ml.
