In order to clarify the differences among biological parameters of Bemisia tabaci biotype Q in different tobacco varieties，we screened resistant varieties against Bemisia tabaci biotype Q. Development and reproduction of Bemisia tabaci biotype Q on six different varieties of tobacco were studied under the laboratory conditions ( 26℃±1℃, RH 70%-80%, photo-period L:D=14:10). The results showed that there were no significant differences among six tobacco varieties during developmental duration, whereas their survival rates, breeding rates and life parameters showed obvious differences. G28, G140, NC95 and K326, which are beneficial for population growth and reproduction of Q-biotype Bemisia tabaci, are susceptible varieties, and K326 is the most sensitive among them, whereas Yunyan85 and Gexin3 are the stronger resistant varieties.
