中文摘要 | 本試驗評估百里香植株、尤加利葉片及白千層葉片3種植物水蒸氣萃取物對福壽螺防治效果。3種萃取物對福壽螺生物活性測定結果顯示:處理後3日百里香31.3 mg kg^(-1)、尤加利62.5 mg kg^(-1)、白千層62.5 mg kg^(-1)對福壽螺致死效果明顯。進一步於盆栽水稻施用百里香、尤加利、白千層萃取物測試福壽螺防治效果,百里香35.7 mg kg^(-1)、尤加利83.3 mg kg^(-1)及白千層83.3 mg kg^(-1)處理後1日福壽螺防治率即達99%以上,秧苗受害率0%。3種植物水蒸氣萃取物對鯉魚生物毒性測定顯示百里香對鯉魚半致死劑量介於30-40 mg kg^(-1)之間,白千層20-40 mg kg^(-1)之間,尤加利80-100 mg kg^(-1)之間。試驗結果顯示,3種植物水蒸氣萃取物在盆栽水稻並不會受土壤影響,與現行苦茶粕防治藥劑並無差異,亦不會對水稻秧苗產生藥害,對福壽螺具有麻醉及快速致死作用。此3種植物水蒸氣萃取物有發展成為植物性殺螺劑的潛力。 |
英文摘要 | This project aims to assess the water distillation extracts of Thyme plant, Eucalyptus leaves and Melaleuca leaves for their control effects on golden apple snail. The results showed that the extracts of Thyme, Eucalyptus and Melaleuca had significant molluscicide effects in three days at the concentration of 31.3, 62.5 and 62.5 mg kg^(-1) respectively. Evaluation of these three kinds of plant extracts for the control of golden apple snail with potted paddy culture showed the mortality of the snail was 99% at the extract concentration of 35.7, 83.3 and 83.3 mg kg^(-1) respectively after 1 day treatment. Mortality of carp fish caused by these water distillation extracts under laboratory condition showed the 50% lethal dose (LD_(50)) ranged between 30-40, 20-40 and 80-100 mg kg^(-1) respectively. The control effect of three kinds of water distillation extracts to snail were not effected when the soil existed, nor cause injury to test paddy and the control effect is as good as tea seed nut. These extracts could lead to anesthesia and rapid death of snails. It suggested that these three kinds of water distillation extracts had the potential for use as a phyto- molluscicide. |
