Frankliniella occidentalis was reared on the leave of bush bean (Phaseolus bulgaris L.). at different temperatures (15℃, 20℃, 25℃ and 30℃) and 75% RH to determine its development rate, development threshold, survival rate and effective accumulative temperature. The results showed that the development rate of F. occidentalis increased significantly as the temperature increased from 15℃ to 30℃. The development threshold of egg, nymphal, prepupal, pupal and adults stages were 5.70℃, 7.04℃, 4.49℃, 6.84℃, and 6.23℃ respectively. The effective accumulative temperature was 219.73day·degree. The survival rate of F. occidentalis was highest at 25℃ (40.12%) and lowest at 30℃ (17.80%).
