[국내논문]다양한 과일나무에서 유래된 추출물의 농업해충 및 저장물해충에 대한 살충활성 Toxicity of various fruit tree extracts to five agricultural and four stored-product anthropod pests원문보기
17과일의 43가지 부위의 메탄을 추출물을 대상으로 5종의 주요 농업해충 및 4종의 저장물 해충에 대한 살충효과를 조사한 효과는 과일류의 종류 및 해충의 종류에 따라 커다란 차이를 보였다. 5,000 ppm 농도에서 80% 이상의 살충효과를 나타내는 10종의 시료를 2,500 ppm에서 살충효과를 검정하였다. 모과와 석류씨가 벼멸구, 포도씨가 복숭아혹진딧물, 유자, 자몽, 메론, 감, 사과, 복숭아, 포도씨가 배추좀나방, 모과씨가 담배거세미나방, 모과와 포도 추출물이 점박이응애에 대하여 80% 이상의 살충효과를 나타냈다. 4종의 저장물해충에 대한 살충효과는 50 ppm의 농도로 처리할 때 모과 및 포도 추출물이 쌀바구미, 모과, 유자, 감 및 포도 추출물이 팥바구미에 대하여 80% 이상의 살충효과를 나타냈다. 그러나 화랑곡나방와 궐련벌레에 대하여는 사용된 과일류의 추출물이 활성을 나타내지 않았다. 이상의 결과로부터 복숭아혹진딧물, 벼멸구, 배추좀나방 담배거세미나방 및 점박이응애에 높은 방제효과를 보인 상기과일류 추출물들은 농업해충 방제제로서 사용 가능성이 예상되었으며, 또한 쌀바구미와 팥바구미에 강한 살충효과를 보인 추출물은 저장물해충방제에 이용할 수 있을 것으로 기대된다.

Methanol extracts from 43 materials of 17 fruit trees were tested for their insecticidal activities toward five agricultural and four stored-product anthropod pests. Efficacy varied with insect species, plant species, and tissue sampled. At a concentration of 2,500 ppm, strong activity was observed with extracts of Chaenomeles sinensis and Punica granatum seeds against Myzus persicae adult females, Vitis vinifera seeds against Nilaparvata lugens adults, Citrus junos, Citrus paradisi, Cucumis melo Linne var. reticulatus, Diospyros kaki, Malus pumila var. dulcissima, Prunug persica, and V. vinifera seeds against Plutella xylostella, Citrus sinensis seeds against Spedoptera litura larvae, and Ch. sinensis and V. vinifera against Tetranychus urticae adults. Against four stored-product insect pests at 50 ppm, seed extracts of Ch. sinensis and V. vinifera against Sitophilus oryzae adults, and Ch. sinensis, C. junos, D. kaki, and V. vinifera against Callosobruchus chinensis adults gave over 80% mortality. Extracts of all samples exhibited little and no activity against Lasioderma serricorne adults and Plodia interpunctella larvae.

Plant materials and sample preparation. The fruits were purchased from Boeun shop, Kyungdong Market, Seoul (Table 1). The insecticidal activities of methanol extracts of test materials from 17 fruit trees in Actinidiaceae (2), Bromeliaceae (2), Cucurbitaceae (5), Ebenaceae (3)z Musaceae (2)z Punicaceae (4), Rosaceae (10), Rutaceae (12), and Vitaceae (3) were tested against five anthropod pests and four stored-product insect pests.
Four stored-product insect pests were used in this study. Laboratory-reared strains of the rice weevil (Sitophilus oryzae L.
In relation to the search for new bioactive substances against agricultural insect pests, we have established a bioassay method suitable for rapid mass-screening of synthetic organic compounds or plant-derived extracts for insecticidal activities with reproducible results’ using only a minute quantity of compounds. Test materials were tested at a concentration of 5,000 and 2, 500 ppm for insect pests. If a fruit extract exhibited activity, titration studies were performed.

Insecticidal activity varied with both the fruit species and anthropod pests. In a test with agricultural anthropod pests, P. xylostella and T. urticae were inhibited more effectively by the application of methanol extracts of various fruits than M. persicae, N. lugens, and S. lituraf and, when tested with four stored-product insects, S. oryzae and C. chinensis were controlled more 아fectively by the application of ethanol extracts of various fruits than L. serricome and P. interpunctella. 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, Rutaceae, Asteraceae, Annonaceae, Labiatae, and Cane- llaceae.
