Three species of parasitoids, Perilitus coccinellae (Schrank) (Hymeoptera: Braconidae), Phalacrotophora sp. (Diptera: Phoridae) and Degeria luctuosa Meigen (Diptera: Tachnidae) were found from the aphidophagous ladybeetle, Harmenia axyridis (Pallas). The parasitoids escaped from the pupal or adult stage of the host. Percentage parasitism of a solitary parasitoid, Perilitus coccinellae showed 5.2%. A gregarious pupal parasitoids, Phalacroto-phora sp. occured an average of 4.38${pm}$12.47 (with a range of 1∼8) from a mummy and showed 0.4∼6.7% of parasitism. A Solitary adult parasitoids, Degeria luctuosa took 17.6${pm}$4.5 days at 25$^{circ}C$, 16 L:8 D in escaping from the host adult collected in late October and early November. The last stadium larva escaped (n=10) became pupa in 9 hours. Adult emergence after pupation (n=42) took 6 to 12 days (mean=8.6 days). Yearly parasitism of Degeria luctuosa showed a fluctuation of 21,1％∼0.7%. The difference between percentage parasitism checked by host disection and the number of the parasitoid escaped was 2.2%, showing about 18% of the parasitoids could not develope normally and died inside of the host body after all. In a labolatory rearing of host collected in field, Degeria luctuosa shortened the longevity of the host adult with a maximum span of 35 days only (about a half of the unparasitized host lived for 3 months), and blocked egg development and the oviposition of the host.
