Abstract

本研究針對臺灣地區真葉蟎屬 (蟎蜱亞綱：絨蟎目：葉蟎科) 物種的分類進行重新評估。過往臺灣的真葉蟎屬 (Eutetranychus) 長期以來均只記錄1 種，即東方真葉蟎 (E. orientalis (Klein))，但近期在臺灣南部的木瓜園中發現了非洲真葉蟎 (E. africanus (Tucker)) 的存在，致使兩種真葉蟎的鑑定問題成為一待解決問題，亦即先前東方真葉蟎鑑定是否有問題。本研究利用真葉蟎調查與過往標本重新鑑定，特別是找尋文獻中的存證標本，旨在精確地鑑定臺灣產真葉蟎物種。研究總計共發現230 隻雌性成蟎、144 隻雄性成蟎及26 隻若蟎 (含第一若蟎與第二若蟎)。全部標本資訊則來自43 筆採集樣本資訊，採集時間自1966−2015 年。鑑定結果表明，包括先前文獻中存證標本在內的所有標本均與非洲真葉蟎的形態特徵相吻合，未發現任何符合東方真葉蟎特徵的標本。這一結果提出了一個新的假設：臺灣可能不存在東方真葉蟎。鑑於此一發現的重要性，本研究呼籲進行更廣泛的樣本蒐集與分析，並進一步整合分子資訊，以確定臺灣真葉蟎屬物種的實際分布情況。本研究的結果對於臺灣乃至全球的農業害蟎管理與生態研究具有深遠的意義，強調了進行物種精確鑑定的重要性與對於農業生態系統的長期監測的需求。 This study conducts a comprehensive reassessment of the classification of the Eutetranychus genus (Acari: Trombidiformes: Tetranychidae) in Taiwan. Historically, only 1 species of this genus, the oriental spider mite (E. orientalis), has been recorded in Taiwan. However, recent discoveries of the African spider mite (E. africanus) in papaya orchards in southern Taiwan have raised questions about the identification of these two spider mite species, specifically whether previous identifications of the oriental spider mite may have been incorrect. By utilizing surveys of spider mites and re-examining past specimens, especially those documented in the literature as voucher specimens, this study aims to accurately determine the species identification of Eutetranychus in Taiwan. The research identified a total of 230 female adult mites, 144 male adult mites, and 26 nymphal mites (including both protonymphs and deutonymphs) from 43 collection records spanning from 1966 to 2015. The results indicate that all specimens, including those previously documented in the literature as oriental spider mites, match the morphological characteristics of the African spider mite, with no specimens found to exhibit characteristics of the oriental spider mite. This finding proposes a new hypothesis: The oriental spider mite may not exist in Taiwan. Given the significance of this discovery, the study calls for more extensive sample collection and the integration of morphological identification with molecular data to ascertain the actual distribution of Eutetranychus species in Taiwan. The findings of this research have profound implications for agricultural pest management of mites and ecological studies in Taiwan and globally, underscoring the importance of accurate species identification and the need for long-term monitoring of agricultural ecosystems.
