摘要

本研究針對台灣農作物害蟲煙草粉蝨種群 (Bemisia tabaci species complex) 及其同屬的粉蝨寄生蜂進行調查分類，主要對象為恩蚜小蜂 (Encarsia) 。自2005年5月至2006年6月，共有212筆粉蝨採集記錄，其中採得恩蚜小蜂90餘筆，共1233隻恩蚜小蜂，並檢查實驗室酒精保存標本448筆，台中霧峰農業試驗所玻片標本400片。共19種恩蚜小蜂，包括一、已記錄種類13種，分別為光胸恩蚜小蜂 (Encarsia aseta Hayat & Polaszek)、紋胸恩蚜小蜂 (Encarsia azimi Hayat)、西捕恩蚜小蜂 (Encarsia cibensis Lopez-Avila)、雙色恩蚜小蜂 (Encarsia duorunga Hayat)、白星海芋恩蚜小蜂 (Encarsia inaron (Walker))、日本恩蚜小蜂 (Encarsia japonica Viggiani)、圓盾恩蚜小蜂 (Encarsia longifasciata Subba Rao)、橘黃恩蚜小蜂 (Encarsia lutea (Masi))、暗澤恩蚜小蜂 (Encarsia obtusiclava Hayat)、網紋恩蚜小蜂 (Encarsia protransvena Viggiani)、淡黃恩蚜小蜂 (Encarsia sophia (Timberlake))、威武恩蚜小蜂 (Encarsia strenua (Silvestri))、聯合恩蚜小蜂 (Encarsia synaptrocera Huang & Polaszek)；二、4新種，分別為黑角恩蚜小蜂 (Encarsia atricornis sp. nov.)、廣興恩蚜小蜂 (Encarsia guangxiana sp. nov.)、黥面恩蚜小蜂 (Encarsia lineolata sp. nov.)、巨翅恩蚜小蜂 (Encarsia maglusalata sp. nov.)；三、2新紀錄種，分別為法西恩蚜小蜂 (Encarsia fuzhouensis Huang & Polaszek)、丑面恩蚜小蜂 (Encarsia perniciosi (Tower))。採集方式利用田間採集、室內寄主飼養。文中並附寄生伯粉蝨恩蚜小蜂之種檢索表、形態圖，寄主、寄主所在植物等資料。

A collection of whiteflies of Bemisia and their Encarsia parasitoids was made during 2005~2006 in Taiwan. All of the Encarsia materials belong to the subfamily Coccophaginae (Hymenoptera: Aphelinidae). In this study, 1233 parasitoids reared from different whiteflies and 400 slide-mounted specimens were preserved in the Taiwan Agricultural Research Institute (TARI). Based on an analysis of these specimens, 19 species belonging to Encarsia from Bemisia were described and illustrated along with data of whitefly hosts and distribution. They include 13 recorded species, namely E. aseta Hayat & Polaszek, E. azimi Hayat, E. cibensis Lopez-Avila, E. duorunga Hayat, E. inaron (Walker), E. japonica Viggiani, E. longifasciata Subba Rao, E. lutea (Masi), E. obtusiclava Hayat, E. protransvena Viggiani, E. sophia (Timberlake), E. strenua (Silvestri), and E. synaptrocera Huang & Polaszek; four new species, namely E. atricornis sp. nov., E. guangxina sp. nov., E. lineolata sp. nov., E. maglusalae sp. nov.; and two new records of species from Taiwan, namely E. fuzhouensis Huang & Polaszek and E. perniciosi (Tower). All specimens described are preserved at National Taiwan University, Taipei, Taiwan. Collecting methods depended on whether the whiteflies were collected in the field or were reared indoors. Furthermore, a key to species of Encarsia from Bemisia is provided along with detailed illustrated figures.
