In the present study,we conducted a reciprocal cross experiment with two hosts(cotton and poinsettia)between B and Q sibling species of Bemisia tabaci to investigate the combined effects of rearing temperature(20℃ and 27℃)and host plants on development and several life history traits of B and Q B.tabaci.We found that the survivorship of B.tabaci immatures(egg to adult),irrespective of B and Q,was independent of rearing temperature and host plants.Females and males of either biotype reared at 27℃developed substantially faster than those at 20℃.However, female lifetime fecundity and female adult longevity at 20℃ were significantly higher than those at 27℃ on both host plants.Cotton was more suitable for either B or Q relative to poinsettia.Q gains advantages over B in terms of higher lifetime fecundity and female adult longevity,except slower development at the same rearing temperature and on the same host,which may at least in part shed some light on the displacement of B by Q.
