Abstract： Frankliniella occidentalis (Pergande) is one of the most important invasive pests, which has caused serious damage on leguminous vegetables in Guiyang, Guizhou. The life tables of experimental populations of F. occidentalis feeding on leaves of Glycine max, Vigna sinensis, Phaseolus vulgaris and pod of P. vulgaris were constructed at 25℃. The results showed that the survival rate of immatures of F. occidentalis was highest on pod of P. vulgaris, and it was similar on other three leguminous vegetables. The intrinsic rate of natural increase (r m) was highest on pod of P. vulgaris (0.1626) and lowest on leaf of V. sinensis (0.0834). The net reproductive rate (R0) was highest on pod of P. vulgaris, and lowest on leaf of G. max. The results indicated that pod of P. vulgaris was the most suitable food to F. occidentalis. In stable age composition, the percentage of immature period was higher and that of adulthood was lower.
