摘  要：
【目的】研究华南地区烟粉虱Bemisia tabaci 2种优势寄生蜂古桥桨角蚜小蜂Eretmocerus furuhashii和双斑恩蚜小蜂Encarsia bimaculata不同发育阶段的形态及个体大小.【方法】利用解剖与显微拍照技术比较了2种蚜小蜂的胚后发育过程、个体形态及大小.【结果和结论】2种蚜小蜂的发育世代均经历卵、1~3龄幼虫、预蛹、蛹与成虫7个发育阶段.在相同条件下,古桥桨角蚜小蜂的世代发育历期(15.9 d)要长于双斑恩蚜小蜂(14.4 d);随着发育龄期的增加,2种蚜小蜂的体长、体宽、头长与头宽都不断增加,但古桥桨角蚜小蜂各个虫态的体长、体宽、头长及头宽均明显大于双斑恩蚜小蜂.

摘  要：
【Objective】To investigate the development and morphology of two dominant parasitoids Eretmocerus furuhashii and Encarsia bimaculata of Bemisia tabaci in South China. 【Method】The postembryonal development and ontogeny morphology of two aphelinid parasitoids were investigated by anatomy and microphotograph.【Result and conclusion】Both parasitoid species experienced seven stages in one generation,including egg,1-3 instar larvae,prepupae,pupae and adults,but the developmental time of Er.furuhashii was obviously longer than that En. bimaculata. With the developmental time increased,the body length and width and head of length and width of both parasitoids enlarged. In general,the body and head length and the body and head width of Er. furuhashii were all significantly larger than those of En. bimaculata.
