Abstract: In order to explore the potential of leguminous plants as host plants for rearing Myzus persicae and Aphidius gifuensis, development duration and fecundity of Myzus persicae on four legume species, Pisum sativum, Vicia faba, Glycine max, and Vigna radiata, were tested. Further, biological characteristics, such as emergence rate, body type, adult lifespan, and parasitic capacity, of the wasp Aphidius gifuensis were compared between the wasps reared on leguminous plants, tobacco, and the progeny wasps reared on tobacco from parent wasps reared on V. faba plants. The results showed that aphids reared on G. max and V. radiata plants were of shorter developmental duration than those obtained on the other two plant species and produced offspring aphids of 22.3 and 25.2, respectively, which were significantly higher than that from P. sativum plants (21) and V. faba plants (18.2). Aphids obtained from P. sativum plants were the heaviest. Aphid propagation rate differed significantly between the host plants, and V. radiata was not a suitable host plant for the propagation of aphid and wasp. The emergence rates of mummy obtained from P. sativum plants (67.5%) and from G. max plants (78.33%) were significantly lower than those obtained from the other two plant species. No significant differences in sex ratio of the progeny aphids were detected between the host plant treatments. The adult progeny wasp lifespan (6.9 d) and tibia length of the hinder leg (573.5 μm for female and 493.5μm for male) obtained from tobacco plants were significantly longer than those obtained from the legume plants. The wasp parasitic capacity resulted from different host plants was ranked as:Nicotiana tabacum > V. faba > P. sativum > G. max. In the progeny wasps reared on tobacco from parent wasps reared on V. faba, the performance parameters were all equal or superior to those of the tobacco group. In conclusion, considering rearing period, time and space use efficiency, and economic cost, V. faba is potential as the most suitable host plant for the mass rearing of A. gifuensis.
