中文摘要 神澤氏葉? (Tetranychus kanzawai Kishida) 是臺灣地區蔬果常見的重要害蟲,因體形小不易察覺,可能藉由苗的攜帶進入田或設施內。故有必要在苗定植之前,就將棲息在苗上的害蟲加以防除。本試驗係以浸漬方式,測試乳化棕櫚油對神澤氏葉?的防除效果。結果顯示,浸漬1 s,對卵、幼若?及成?分別在2.5、5及5 mL L^(-1) 具有100% 的防除率。而增加浸漬時間至4 s 並未顯著增加?的防除率。因此,如果要應用棕櫚油來防堵苗攜帶神澤氏葉?,可用浸漬的方式處理苗,而有效濃度為5 mL L^(-1),但經濟有效濃度須再進一步測試,有可能在2.5-5 mL L^(-1) 之間,且僅浸漬約1s即有效果。
英文摘要 The Kanzawa spider mite (Tetranychus kanzawai Kishida) is a popular pest on vegetables in Taiwan. It may invade into field or farming facility through entrainment by seedling. Thus, it is necessary to completely get rid of this insect pest that infests seedlings before planting. In this experiment, a dipping method was conducted to examine the acaricidal efficacy of emulsified palm oil against the Kanzawa spider mite. The results revealed that 100% mortality of egg, larva-nymph and adult reached as they were treated with 2.5, 5, and 5 mL L^(-1), respectively. However, there was no increase in the mortality when increased the dipping duration up to 4 seconds. Therefore, dipping is a useful method, with effective concentration of 5 mL L^(-1). However, the cost-effective concentration needs further tests. Its effective concentration may be between 2.5-5 mL L^(-1), by dipping for 1 second, if palm oil is used for controlling the Kanzawa spider mite on seedling.
