摘　　要：【目的】研究烟粉虱Bemisia tabaci(Gennadius)对同种寄主不同品种的选择性及适生性,可为该寄主抗性品种的选育和烟粉虱的综合治理提供理论依据。【方法】在温度(29±2)℃、湿度80%±5%的自然光照温室内,进行B型烟粉虱对不同茄子品种的选择性以及这些品种对其生长发育、繁殖、存活和生命表参数的影响实验。【结果】B型烟粉虱对茄子不同品种的选择及适生性具有一定的差异,在14个茄子品种或材料中,B型烟粉虱对黑马紫长茄的选择性最强,对龙茄1号的选择性最弱;B型烟粉虱从卵发育到成虫的存活率在辽茄3号上最低,在龙茄1号上最高;世代发育历期在辽茄3号上最短,在徐州长茄上最长。此外,B型烟粉虱在苏崎茄、扬茄1号和紫圆茄上的种群趋势指数(I)分别为68.7215、37.4675、25.6245,表明B型烟粉虱对这3个品种的适生性为苏崎茄>扬茄1号>紫圆茄。[Objectives] To provide basic information for developing new varieties of whitefly-resistant eggplants, and to investigate the host-preferences for, and fitness of, Bemisia tabaci （Gemladius） B-biotype with respect to different eggplant varieties. [Methods] The preference of B. tabaci B-biotype for different varieties of eggplant and the effect of feeding on different eggplant varieties on B. tabaci B-biotype＇s growth, production, survival and life-table parameters were studied in a greenhouse under T=（29~2）~C, RH=80o/~：5% and natural lighting. [Results] The results show that the B. tabaci B-biotype clearly preferred some of the fourteen varieties, or strains, of eggplant tested, over others. The most preferred eggplant variety was Heimazichangqie and the least preferred was Longqie No.1. The survival and the reproduction of B. tabaci also differed significantly on the different varieties, or strains, of eggplant; highest fitness was observed on Longqie No.I, and the lowest on Liaoqie No.3. The shortest developmental duration was on Liaoqie No.3 and the longest on Xuzhouchangqie. The population trend index （1） on the Suqiqie, Yangqie No. 1 and Ziyuanqie eggplant varieties was 8.7215, 37.4675 and 25.6245, respectively, and the relative fitness of Bemisia tabaci on these eggplant varieties was, in descending order, Suqiqie〉Yangqie No. 1〉Ziyuanqie.
