2、表明，柑橘上的尼氏真綏螨成螨對柑橘紅蜘蛛成螨的日均捕食量最大，顯著高于紫蘇；而梧桐、薄荷和茶葉3種寄主上的尼氏真綏螨對柑橘紅蜘蛛雌成螨的捕食力與柑橘上的無顯著差異。對柑橘紅蜘蛛若螨的捕食能力以薄荷和梧桐上的顯著為高，柑橘和茶葉上的次之，紫蘇上的最低；而5種寄主上的尼氏真綏螨對柑橘紅蜘蛛幼螨的日均捕食量之間無顯著差異。對柑橘紅蜘蛛成螨的持續(xù)捕食能力結(jié)果顯示，各處理連續(xù)3天的日均捕食量基本呈現(xiàn)略微降低的趨勢，但3天之間均無顯著差異。上述結(jié)果證明不同寄主上的尼氏真綏對柑橘紅蜘蛛的捕食能力存在差異，且對柑橘紅蜘蛛成螨的捕食能力較為穩(wěn)定。關(guān)鍵詞：尼氏真綏螨；柑橘紅蜘蛛
