배추좀나방과 담배거세미나방 유충에 대한 한방식물체 추출물의 살충 및 섭식저해활성

Larvicidal and Antifeeding Activities of Oriental Medicinal Plant Extracts against Plutella xylostella and Spodoptera litura

17종과 45종 한방 식물체 메탄올 추출물의 배추좀나방과 담배거세미나방 유충에 대한 살충활성 및 섭식저해활성을 잎침지법으로 조사하였다. 살충활성은 8,000 ppm에서 조사하였는바, 현호색 추출물만이 담배거세미나방 유충에 대해 강한 살충활성을 보였다. 섭식저해활성은 5,000 ppm에서 조사한 결과, 누리장나무, 거문누리장나무, 목향, 우방자, 인진, 전호, 백지 및 현호색 추출물이 강한 섭식저해활성을 나타내었다.

Methanol extracts from 45 species of oriental medicinal plants belonging to 17 families were subjected to a screening test for their larvicidal and antifeeding activities against two species of lepidopteran larvae, diamondback moth (Plutella xylostella L.) and tobacco cutworm (Spodoptera litura F.) by a leaf-dipping method. At a concentration of 8,000 ppm, methanol extract of Corydalis turrschaninovii roots only was found to have potent larvicidal activity against S. litura. At 5,000 ppm, strong antifeeding activity against both larvae was observed from the extracts of Clerodendron trichotomum, C. trichotomum var. esculentum, Inura helenium, Arctium lappa, Artemisia messerschmidtiana, Anthriscus sylvestris, Angelica dahurica, and C. turrschaninovii.
