Abstract: The selectivity and fitness of B-biotype of Bemisia tabaci(Gennadius) on different varieties of cotton was studied in lab. The results showed that the number of adult and egg on glandless cotton line ZH05372 was highest, and the ratio was 46.1% and 47.7%, respectively. The lowest was 23.4% and 23.1% on Cikang 1. There was significant difference in the fitness of B-biotype of Bemisia tabaci(Gennadius) on different varieties of cotton, indicating that the longest nymphal stage was found on ZH05372 and the survival rate of nymph was highest, while the verse trend was found on Zhecaimian 2 and Cikang 1. The longevity of adults on glandless cotton was also longer than those on the other two varieties. The fecundity on glandless cotton ZH05372 and Cikang 1 were greatly more than that on Zhecaimian 2.

Key words: Bemisia tabaci, B-biotype, cotton, selectivity, ecological fitness
