中文摘要 | 小黃薊馬(Scirtothrips dorsalis Hood)在檬果(Mangifera indica Linn.)上發生嚴重,為提供防治用藥之建議,以浸葉餵食法測試30種殺蟲劑對小黃薊馬成蟲之毒效,結果以滅大松40% EC 1000倍、加保扶44% SC 800倍、丁基加保扶48.34% EC 1000倍、賜諾殺2.5% SC 2000倍、芬殺松50% EC 1000倍、滅賜克50% WP 1000倍和納乃得40% SP 800倍對小黃薊馬的毒效最佳,24小時的死亡率達90.6-100%,7種藥劑的殺蟲效果無顯著差異;其次為納乃得24% SL 500倍、馬拉松50% EC 500倍和撲芬松30% EC 800倍處理的效果,24小時的死亡率達72.8-82.1%。其它20種供試藥劑之登記稀釋倍數效果均不佳,經處理後24小時均仍有半數以上之供試小黃薊馬存活。研究結果顯示滅大松、芬殺松、加保扶、丁基加保扶、納乃得、滅賜克和賜諾殺等7種殺蟲劑具有防治檬果上小黃薊馬的潛力。 |
英文摘要 | Scirtothrips dorsalis Hood is a serious pest of mango (Mangifera indica Linn.) in Taiwan. This study was conducted to determine efficacy of 30 insecticides for control of adult S. dorsalis by the feeding trials on insecticide-treated leaves of mango. Results showed that, after feeding for 24 hours, the mortality of thrips was the highest (90.6 to 100%) for the treatments of methidathion 40% EC, carbofuran 44% SC, carbosulfan 48.34% EC, spinosad 2.5% SC, fenthion 50% EC, methiocarb 50% WP, and methomyl 40% SP. The mortality of thrips was moderate (72.8 to 82.1%) for the treatments of methomyl 24% SL, malathion 50% EC, and fenvalerate mixed with fenitrothion 30% EC, whereas the mortality was low (<50%) for the rest of the 20 insecticides tested. This study suggests that the seven insecticides (methidathion, carbofuran, carbosulfan, spinosad, fenthion, methiocarb, and methomyl) may be of potential for control of S. dorsalis in commercial fields of mango in Taiwan. |
