Furthermore, I A. pisum i -reared larger I A. asychis i also parasitized more I M. persicae i and I A. pisum i than I S. avenae i -reared smaller I A. asychis i , while the parasitic capacity of I A. asychis i on I S. avenae i was not affected by host aphids. However, whether I A. pisum i is a suitable host for mass-rearing I A. asychis, i or whether I A. asychis i reared on a larger host aphid ( I A. pisum i ) could be more advantageous for further biological control has never been examined. In aphid parasitoids, I S. avenae i is one of the most common host aphids used for mass-rearing aphid parasitoids [[19]]. When provided with I M. persicae i and I A. pisum i , AP-reared I A. asychis i parasitized more aphids than that of the SA-reared I A. asychis i ( I A. pisum i : I t i = 1.319, df = 4, I p i = 0.2575; I M. persicae i : I t i = 2.706, df = 8, I p i = 0.0268).
