Abstract: The effects of four leguminous host plants on growth and development of Arma chinensis were determined. The results show that host plants had no effect on nymphal weight, adult sex ratio, fecundity and egg hatching rate. The fecundity of A. chinensis fed Phaseolus vulgaris was 24.13, and the egg hatching rate was 59.34%, which were significantly lower than those of the control and the other host plant groups. The developmental duratioin and pre-oviposition period in the Vicia faba group and the Pisum sativum group were significantly lower than those in the control and the other host plant groups. The weight of A. chinensis in the V. faba and P. sativum groups increased significantly. The survival rates of A. chinensis in V. faba (83.62%) and P. sativum (84.36%) were significantly higher than those in the control and the other host plant groups. V. faba and P. sativum seedlings grew quicker and could be used for a longer time. In conclusion, V. faba and P. sativum seedlings can be used as alternative host plants for large-scale rearing of A. chinensis.
