46종 채소류의 에탄을 추출물을 대상으로 5종의 주요 농업해충 및 4종의 저장물 해충에 대한 살충효과를 조사한 효과는 채소류의 종류 및 해충의 종류에 따라 커다란 차이를 보였다. 5종의 농업해충에 대한 살충효과는 5,000 ppm의 농도로 처리할 때 연근 및 파래는 복숭아혹진딧물, 옥수수 및 옥수수 잎은 벼멸구, 수박씨 및 파래는 배추좀나방, 연근, 옥수수 및 옥수수 잎은 담배거세미나방, 수박씨, 당근, 해바라기 잎과 꽃, 상추 및 생강은 점박이응애에 대하여 80% 이상치 살충효과를 나타냈다. 2,500 ppm의 농도로 처리할 때는 연근 및 파래는 복숭아혹진딧물, 옥수수는 벼멸구, 수박씨 및 파래는 배추좀나방, 연근 및 옥수수는 담배거세미나방, 수박씨, 해바라기 꽃 및 상추는 점박이응애에 대하여 80% 이상의 살충효과를 나타냈다. 4종의 저장물해충에 대한 살충효과는 50 ppm의 농도로 처리할 때 수박씨 및 호박씨는 쌀바구미, 수박씨, 해바라기씨 및 생강은 화랑곡나방에 대하여 80% 이상의 살충효과를 나타냈다. 팥바구미와 궐련벌레에 대하여는 사용된 채소류의 추출물이 활성을 나타내지 않았다. 이상의 결과로부터 복숭아혹진딧물, 벼멸구, 배추좀나방, 담배거세미나방 및 점박이응애에 높은 방제효과를 보인 상기 채소류 추출물들은 공업해충 방제제로서 사용 가능성이 예상되었으며, 또한 쌀바구미와 화랑곡나방에 강한 살충효과를 보인 추출물은 저장물해풍방제에 이용할 수 있을 것으로 기대되었다.

Ethanol extracts from 46 vegetables were tested their insecticidal activities toward five agricultural insect pests and four stored-product insect pests. The efficacy varied with both agricultural insects/stored-product insects and vegetable species used. Potent insecticidal activities, at the concentration of 5,000 ppm, were produced from extracts of Nelumbo nucifera and Ulva lactuca against Myzus persicae, Zea ways and Z. mays (leaf) against Nilaparvata lugens, Citrullus vulgaris (seed) and U. lactuca against Plutella xylostella, N. nucifera, Z. mays, and Z. mays (leaf) against Spodoptera litura, and C. vulgaris (seed), Daucus carota, Helianthus annuus (leaf), H. annuus (flower), Lactuca sativa, and Zingiber officinale against Tetranychus urticae. Potent insecticidal activities at the concentration of 2,500 ppm were exhibited from the extracts of N. nucifera and U. lactuca against M. persicae, Z. mays against N. lugens, C. vulgaris (seed) and U. lactuca against xylostella, N. nucifera and Z. mays against S. litura, and C. vulgaris (seed), H. annuus (flower), and L. santiva against T. urticae. Against four stored-product insect pests at 50 ppm, extracts of C. vulgaris (seed) and Cucurbita moschatla (seed) against Sitophilus oryzae and C. vulgaris (seed), H. annuus (seed), and Z. officinale against Plodia interpunctellfa revealed potent insecticidal activities over 80% mortality. In tests with Callosobruchus chininsis and Lasioderma serricorne, extracts of all vegetables tested exhibited meager and no activity.

대상 데이터
Five agricultural insect pests were used in this study. Brown plaiithopper (Nilapawata lugens Stal) was reared on rice plant {Oryza sativa L.
) seedlings (7—10 days after germination) in acrylic cages (26 X 30 X 20 cm). Green peach aphid (Myzus persicae Sulzer) and diamondback moth (Pmtdla xylostella L.) were reared on tobacco plant (Nicotiana tabacum L.) and beet (Rhaphanus sativas L.) seedlings (5 — 6 days after germination), respectively, in acrylic cages (26 X 30 X 20 cm). Tobacco cutworm (Spodoptera litura Fab.
Four stored-product inse가 pests were used in this study. Laboratory-reared strains of S.

Spray method was used for the bioassay of N. lugens (BPH). Twenty female adults were transferred into a test tube (3 x 20 cm) containing five 'Chucheong1 rice seedlings wrapped with cotton and 20 ml water.
성능/효과
litura, but moderate activities were produced in extracts of Actinidia arguta and Allium monanthum. In the test with T. urticae, strong insecticidal activities over 80% mortality were observed in extracts of C. vulgaris (seed), Daucus carota, Helianthus annuus (leaf), H. annuus (flower), Lactuca sativa, and Zingiber officinale. Furthermore, moderate activities were observed in extracts of 9 vegetables.
In tliis study with 70% ethanol extracts from 46 vegetables belonging to the family Actinidiaceae, Amaranthaceae, Araceae, Brassicaceae, Chenopodiaceae, Compositae, Convolvulaceae, Crassulaceae, Cucurbita- ceaez Gramineae, Labiatae, Liliaceae, Malvaceae, Nymphaeaceae, Rosaceae, Solanaceae, Umbelliferaeceae, Ulvaceae, and Zingiberaceae, many of them showed potent insecticidal activity against the economically important insect pests and stored-product insect pests. Insecticidal activity varied with both the ve응etable species and agricultural insects/ stored-product insects tested.
Insecticidal activity varied with both the ve응etable species and agricultural insects/ stored-product insects tested. In tlie test with agricultural insect pests, T.urticae was inhibited more 산festively by the application of ethanol extracts of various vegetables than M. persicae, N. lugens, P. xylostella, and S. litura, and, when tested with four stored-product insects, S. oryzae and P. interpunctella were controlled more effectiv이y by the application of ethanol extracts of various vegetables than C. chinensis and L. serricorne. Jacobson (1989) pointed out that the most promising botanicals as sources of novel plant-based insecticides at present and in the future are species of the families Meliaceae, Rutaceaez Asteraceae, Annonaceae, Labiatae, and Canellaceae.
In this study, significant insecticidal activity over 80% mortality at 2, 500 ppm was observed in extracts of N. nucifera and U. lactuca against M. persicae, Z. mays against N. lugens, C. vulgaris (seed) and U. lactuca against P. xylostella, N. nucifera and Z. mays against S. lituraf and C. vulgaris (seed), H. annuus (flower), and L. sativa against T. urticae, although remaining samples tested were ineffective to M. persicae, N, lugensf P. xylostella, S. litura, and T. urtiaze. Furthermore, when treated with stored-product insect pests, strong insecticidal activity exhibited from extracts of C.
urtiaze. Furthermore, when treated with stored-product insect pests, strong insecticidal activity exhibited from extracts of C. vulgaris (seed) against S. oryzae and P. interpunctella, C. moschata (seed) against S. oryzae, H. annuss (seed), and Z. officinale against P. interpunctella, whereas all vegetable extracts revealed weak or no inhibition against C. chinensis and L. serricorne. The vegetables above indicated confirm their superiority and usefulness as a potent insecticide.
In conclusion, the vegetable-derived materials might be useful for developing new types of insecticides, and biorational management agents for controlling insect pests and stored-product insect pests on crops at same time, although their effects on natural enemies, vegetable qualities, or environment has not been fully clarified.
