中文摘要：
生物测定是检测害虫抗药性的一项重要技术。利用100mL插口圆底聚丙烯离心管对现在应用较多的粉虱成虫生物测定方法——琼脂保湿浸叶法进行了改进。改进后的方法不影响粉虱成虫的持续取食,具有操作简单、结果重复性好及无需对成虫麻醉等优点。同时发现茄子叶片对于B型烟粉虱Bemisia tabaci（Gennadius）B-biotype和温室白粉虱Trialeurodes vaporariorum（Westwood）成虫均是一种非常适合的生测材料。利用该方法分3次独立测定了烯啶虫胺对B型烟粉虱和温室白粉虱混合日龄成虫的毒力,结果具有很好的重复性。
英文摘要：
Bioassay is a very important technique for insecticide resistance detection.An improved bioassay method for adults of Bemisia tabaci （Gennadius）and Trialeurodes vaporariorum （Westwood）was reported in present paper.This method primarily composed of a cylinder tube,made from a centrifuge tube （38 mm in diameter and 107 mm in length） with bottom cut off and replaced with a piece of black cotton cloth to do the test.The nitenpyram treated eggplant-leaf disc,which was proved here to be a good material for the bioassay of adult whiteflies,was laid abaxial side down on a bed of agar gel inside the lid of the tube.The improved bioassay method described here offered a dependable,accurate,and relatively simple means to explore dose-response relationships in evaluating susceptibility of adult whiteflies to different varieties of insecticides.
