中文摘要 | 本研究之目的在調查蕹菜有害生物種類及其危害習性,並探討非化學農藥防治之效果。調查結果顯示,在桃園地區蕹菜計有18種有害生物,其中以甘薯金花蟲(Chaetocnema confinis Crotch)、甘薯猿葉蟲(Corasposoma dauricun)、大黑星龜金花蟲(Aspidomorpha miliaris (Fabricius))、甘薯綠背金花蟲(Meteriona circumdata)、斜紋夜盜蟲(Spodoptera litura Fabricius)、野蛞蝓(Limacella agrestisurarians Adams)、神澤氏葉?(Tetranychus kanazawai Kishida)、銀葉粉蝨(Bemissia argentifolii Bellows & Perring)等八種危害最嚴重。害蟲危害率調查顯示,以台刈宿根露天栽培蟲害發生較多,銀葉粉蝨及神澤氏葉?較嚴重。施用不同添加物於土壤防治土棲有害生物之試驗結果顯示,以聚乙醛粒劑、苦茶楂、氰氮化鈣、稻草灰撒佈可以顯著降低蝸牛及蛞蝓危害。天然物質藥效篩選試驗結果顯示,以煙草屑溶液500倍及4.5%苦楝精E.C.1000倍對甘薯金花蟲防治效果最佳。 |
英文摘要 | The objectives of this study were to investigate and identify the key pests of water convolvulus and to determine the best non-chemical control method against the key pests. About eighteen insect pests species were confirmed to be able to infest water convolvulus in Taoyuan district. Among them 8 species, namely Chaetocnema confinis Crotch, Corasposoma dauricun, Aspidomorpha miliaris (Fabricius), Meteriona circumdata, Spodoptera litura Fabricius, Limacella agrestisurarians Adams, Tetranychus kanazawai Kishida and Bemissia argentifolii Bellows & Perring, were most injurious in the field. The results of the field trials indicated that ratoon cultivation in open-field was more serious damaged by insect pests. The silverleaf white flies and Kanzawa spider mites were most serious in the plastic house. Application with 6% Metaldehyde G., tea seed dust, rice straw ashes and Calcium cyanide treatment in soil were found to be effective against the snails and slugs. The screening tests in plastic house indicated that Nicotine solution 500x and 4.5 % Neemix E.C.1000 x were effective against sweet potato flea beetle. |
