中文摘要 | 調查本省中部地區玫瑰葉�虩媄�發現,玫瑰上主要葉�藀酗T種,以二點葉�� (Tetranychus urticae Koch) 的出現頻率最高, 佔總採樣區的 87.7%, 其次是神澤葉�� (T. kanzawai Kishida) 約佔 7.6%,柑桔葉�� (Panonychus citri McGregor) 為最低,僅 佔 1.9%。 又於室內測試常用殺�蟛笆黚姪A葉�薴妞r性反應, 結果顯示, 神澤葉�薾� Bifenthrin、Fenpropathrin、Fenbutatin-oxide、Clofentesine 呈低度抗性,對 Amitraz 則無抗性產生。另於田間,以兩種施藥時間間隔方式,分別進行二點葉�薴巹姪A葉�薴夾儐v 效果評估。 以防治玫瑰上二點葉�藀茖央A 2% Abamectin E.C. 及 68.1% Propargite E.C. 以慣行施藥方法防治效果較佳, 而 2.8% Bifenthrin E.C. 及 38% Dienochlor F. 則以每 隔 3 天施藥一次, 連續兩次者防治效果較佳。 以防治玫瑰上神澤葉�藀茖央A 68.1% Propagrite E.C. 以慣行施藥方式防治效果較差, 而 38% Dienochlor F. 在兩種施藥時間 間隔方式比較,兩者間並無顯著差異。 |
英文摘要 | A recent survey revealed that the three most common spider mites and their appearance frequency on roses in control Taiwan were the two-potted spider mite, Tetranychus urticae Koch, 87.9%;the Kanzawa spider mite, Tetranychus kanzawai Kishide, 7.6%; and the citrus red mite, Panonychus citri (McGregor). 1.9%. Laboratoy test showed that the Kanzawa spider rnite, while fully susceptible to amitraz, had low level of resistance to several commonly used acaricides including bifenthrin, fenpropathuin, fenbutatin-oxide and clofentezine. Field experiments using two application intervals showed that 2% abamectin EC and 68.1% propargite EC applied conventionally, and 2.8% bienthrin CE and 33% dienochlor F. applied twice at an intervalof 3-days, gave better control of the two-spotted spider mites on roses. For the kanzawa spider mites, conventional application of 68.1% propargite EC was less effective while no significant deference was observed between the two application regimes for 38% dienochlor F. |
