Abstract: This paper studied the effects of four leguminous host plants and five temperature regimes on the growth and development of Frankliniella occidentalis, and analyzed the start temperature for F. occidentalis development and the effective accumulative temperature for this thrips at its different development stages. At the same temperature regimes, there was a significant difference in the development of F. occidentalis feeding on different host plants, and at different temperature regimes, this difference was not the same. The development of immature F. occidentalis was the fastest when feeding on Phaseolus vulgaris, while the slowest when feeding on Vicia faba, with a significant difference between them. The development of the thrips at each development stage decreased with increasing temperature, and there was a linear relationship between the developmental rate and temperature. The start temperature for F. occidentalis development and the effective accumulative temperature for this thrips at its different development stages differed with host plants, being the lowest (6.35 ℃) and the highest (331.36 degree-days) for the immature F. occidentalis on V. faba, respectively.
