Abstract: The development, longevity, fecundity and survivorship of Bemisia tabaci biotype B on Cucumis sativas L. (Beijing 202) at 7 constant temperatures (18, 21, 24, 27, 30, 33 and 36℃) and 3 humidity (55%, 75% and 95% RH) were studied. It showed that the developmental periods had 33.6 d from egg to adult at 18℃, and decreased as temperature increased. At 33℃ it takes 14.4 d to complete the period. The optimal range of temperature for B. tabaci biotype B development was from 27 to 33℃. The total survivorship of egg and larva was highest at 27℃. Extremely low and high temperature delayed the development and survivorship. Longevity of adult was shortened as temperature increased, varied from 41.3 to 10.4 at the range of 18-36℃, while the same changes happened in the fecundity per female. The total survivorship of egg and larva was highest (77.8%) at 75% RH. Longevity of adult was 27.5, 31.2 and 15.7 d and fecundity was 264.3, 220.0 and 110.4 per female at 55%, 75% and 95% RH respectively.
