The development period, survival rate, longevity and fecundity of two whiteflies, Bemisia tabaci B-biotype and Trialeurodes vaporariorum (Homoptera: Aleyrodidae) were compared under different temperature laboratory conditions (15 degree C, 18 degree C, 21 degree C and 24 degree C). Egg development of B. tabaci B-biotype was significantly longer compared with that of T. vaporariorum at 15 degree C, 18 degree C and 24 degree C. Significantly longer pseudo-pupae development and lower survival rate were found in B. tabaci B-biotype at 15 degree C compared with those at 18 degree C, 21 degree C and 24 degree C. Significantly higher fecundity was found in B. tabaci B-biotype at 24 degree C compared with that at 15 degree C, 18 degree C and 21 degree C. However, the fecundity of T. vaporariorum was significantly lower at 24 degree C relative to that at 15 degree C, 18 degree C and 21 degree C. Significantly shorter 1st instar larval development was found in T. vaporariorum compared with that of B. tabaci at 15 degree C and 18 degree C. Significantly longer 2nd instar larval development was found in B. tabaci and T. vaporariorum at 15 degree C compared with that at 18 degree C, 21 degree C and 24 degree C. However, significantly shorter 3rd instar larval development was found in T. vaporariorum compared with that of B. tabaci at 15 degree C, 18 degree C and 24 degree C. The adaptive divergence of tolerance to relatively low temperature may be an important factor that results in the interspecific differentiation between the seasonal dynamics of these two whiteflies in China.
