마늘 추출액과 솔잎 가루를 이용한 크라프트지의 쌀벌레 방제 효과

Abstract

This study developed rice packaging paper with exterminating performance against rice weevils such as and Sitophilus oryzae. The exterminating performance of packaging paper was given by treatment of garlic extractives and pine-leaf powder, respectively. For the exterminating test, rice weevils were put in petri dish containing non-treated packaging paper and functional packaging paper for twenty days. Right after being put in the petri dish, the rice weevils moved fast toward the area in the non-treated paper escaping from that in the functional paper. The lethality of the rice weevils on the functional paper reached over 50 per cent. The physical properties of the functional packaging paper were rarely changed in spite of treatment of the exterminating agents.
