Expression of Fusion Protein with Autographa californica Nuclear Polyhedrosis Virus Polyhedrin and Bacillus thuringiensis cryIA(c) Crystal Protein in Insect Cells
남부지방에서 분리한 곤충병원성곰팡이 Beauveria bassiana GY1-17균주를 이용하여 산림해충인 오리나무잎벌레(Agelastica coerulea), 밤나무혹나방(Meganola melancholica), 회양목명나방(Glyphodes perspectalis), 잔디해충인 등얼룩풍뎅이(Blitopertha orientalis), 채소해충인 배추좀나방(Plutella xylostella) 및 거세미나방(Agrotis segetum)의 생물적 방제 가능성을 알아보기 위하여 실험한 결과, 오리나무잎벌레와 배추좀나방유충은 7.0~2.0 conidia/ml 농도에서 처리 7일과 5일후 100%의 치사율을 나타내었다. 밤나무혹나방유충은 0.03875~3.1 conidia/ml 처리에서 66.7~100%의 높은 치사율을 보였으나 회양목명나방유충은 2.0~2.0conidia/ml 처리에서도 전혀 치사되지 않았다. 등얼룩풍뎅이유충은 3.7 conidia/ml 농도에서 46.7%의 치사율을 보였고, 거세미나방유충은 2.5 conidia/ml 농도에서 63.3% 치사율을 나타내었다.
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.
