In order to effectively control Myzus persicae using the parasitoid Aphelinus asychis as a biological control agent in the greenhouse, biological characteristics such as the effect of temperature, host stage and host plant on parasitization, fecundity, longevity, sex ratio, development time, behavioral response on host, host plant and oviposition and host feeding behavior of A. asychis were evaluated. When A. asychis exposed to 40 individuals of each instar of M. persicae for 24 h at 25°C, 1st, 2nd, 3rd, 4th instar nymphs and adult were parasitized at 47.8%, 70.0%, 32.2%, 14.4% and 7.8%, respectively. There was a difference in the amount of parasitism depending on the host plant utilized by M. persicae. Aphids were most heavily parasitized on Chinese cabbage (44.1%) followed by pepper (34.2%). The lowest parasitization occurred on aphids reared on radish (23.3%). Second instar nymphs were most heavily parasitized and adult aphids were rarely successfully utilized.
