中文摘要:为明确浙江省不同地区以及不同寄主植物上的烟粉虱Bemisia tabaci寄生蜂种类,更好地利用寄生蜂对烟粉虱进行生物防治,通过对浙江省8个地区进行田间烟粉虱末期若虫或伪蛹采样,并将其带回实验室内饲养直至寄生蜂成蜂羽化进行形态学鉴定。结果表明,在浙江省8个地区共采集到3490头烟粉虱寄生蜂,其中蒙氏桨角蚜小蜂Eretmocerus mundus Mercet、狄氏桨角蚜小蜂Eretmocerus debachi Rose & Rosen和浅黄恩蚜小蜂Encarsia sophia (Girault & Dodd)的数量最多,比例分别达到了53.0%、27.8%和9.9%;在温州发现的寄生蜂种类最多,共有10种;在20种寄主植物种类或品种上共发现10余种烟粉虱寄生蜂,其中17种寄主植物上共有的烟粉虱寄生蜂有蒙氏桨角蚜小蜂、12种寄主植物上共有的是浅黄恩蚜小蜂、10种寄主植物上共有的是狄氏桨角蚜小蜂;表明这3种寄生蜂是浙江省广泛分布的优势种类。

Abstract:In order to investigate the hymenopteran parasitoids of the whitefly Bemisia tabaci in Zhejiang, east of China, the later-instar nymphs and pseudopupae of B. tabaci were sampled from various host plants in Hangzhou, Ningbo and Wenzhou biweekly or monthly and in other regions of Zhejiang irregularly. All samples were brought back to the laboratory for rearing until the emergence of parasitoids for identification. The results showed that the greatest diversity of native parasitoid species attacking B. tabaci was observed in Wenzhou. Ten species of parasitoids were found, which emerged from the whiteflies on 21 host plants. Eretmocerus mundus was found to emerge from the whiteflies on 17 host plants, Encarsia sophia on 12 host plants, and Eretmocerus debachi on ten host plants. Er. mundus, Er. debachi and En. sophia were the most abundant parasitoids, accounting for 53.0%, 27.8% and 9.9% of all parasitoid specimens reared from B. tabaci, respectively, indicating that these three species were the dominant parasitoids of B. tabaci distributed in Zhejiang Province.
