Abstract

Insecticidal efficacies of plant extracts and environmental friendly agro-materials against green peach aphids, two spotted spider mites, and diamondback moths were evaluated in the lab condition. Oxymatrine and matrine, derivatives of Sophora flavescens, were effective to all three tested pest insect species. Selected environmental friendly agro-materials available from the market mainly contained active ingredients of nicotine, azadirachtin, and matrine were all effective to control green peach aphids and two spotted spider mites.

친환경농산물 재배농가에서 해충방제용으로 널리 사용하고 있는 천연식물추출물과 목록공시된 친환경유기농자재를 대상으로 점박이응애, 복숭아혹진딧물, 배추좀나방에 대한 살충효과를 검정하였다. 천연식물추출물 중 고삼뿌리추출물(oxymatrine)이 복숭아혹진딧물(72.1%)과 점박이응애(98%)에 대한 살충효과가 가장 높았으며 고삼추출물(matrine)이 배추좀나방에 대한 살충효과가 가장 높았다(97%). 목록공시된 친환경유기농자재 중 담배잎추출물, 고삼추출물, 멀구슬나무추출물 유래 자재를 선발하여 복숭아혹진딧물과 점박이응애에 대한 살충효과를 검정해본 결과(~98%) 높은 살충력을 보여주었다.
