Abstract

The hemolmyph and whole body of insect, Bombyx mori, Allomyrina dichotoma and Neotocia brevitarsi, conspicuously inhibited the mycelial growth of several plant pathogenic fungi. The hemolymph of 1087 strain among the 16 strains of B. mori has inhibition activities against the 3 species of fungi, Alternaria panax, Collctotrichum gloeosporioides, and Pyricularia oryzae. The whole body of B. mori was more effective than the hemolymph as a inhibitor on fungi growth. The antifungal activity of B. mori was variable to the fungi species. In addition, A. dichotoma and N. brevitarsi showed antifungal activities against the same fungi as did B. mori. These data showed that the insect has potent antifungal activity. Whereas, the level of activities were differ according to the fungal species. This finding underlines that the possibility of the insect can be use of the agent as a inhibitor against the plant pathogenic fungi.

본 연구는 식물병원성곰팡이에 대한 곤충 혈액 및 유충체의 항곰팡이 활성을 조사하였다. 집누에, 장수풍뎅이, 흰점박이 꽃무지 모두 곰팡이 저해활성을 나타냈으며, 집누에의 계통간 비교에서는 1087계통의 활성이 가장 높았다. 또한, 혈액보다는 유충체를 이용한 경우가 더 강한 항곰팡이 활성을 나타냈다. 곤충의 항곰팡이 활성은 곰팡이균주에 따라 다르며, 본 연구에 사용된 3종은 A. panax, C. gloeosporioides 및 P. oryzae 균에 항곰팡이 활성을 가진다.
