This study was investigation for primary bionomical characteristics, emergence rate of wintering type pupa and oviposition preference, of Papilio xuthus. The emergence rate of wintering type pupa stored at cold chamber(4 ± 1oC) was 85%, after 10 months. The average emergence rate of wintering type pupa during storage was 89.6%, and the emergence periods were 7.9 ± 1.9days in room temperature. Mating ratio in large oviposition room, 6,000 × 6,000 × 3,500 mm(W × L × H), was 86.7 ± 5.8% higher than 63.3 ± 15.3% in small room, 2,500 × 3,000 × 2,000 mm(W × L × H). But the number of eggs in the large room were 137.0 ± 16.5 fewer than 141.7 ± 20.4 in the small room. As a result of oviposition preference experiment on three different host plants, 10 mated female laid 141.7 ± 27.8 on the leaves of Phellodendron amurensew more than 67.7 ± 20.6 on Zanthoxylum schinifolium and 77.0 ± 21.8 on Citrus unshiu. The egg periods were 4.4 ± 0.8 days after oviposition, and the hatchability was 92.2% in 25oC room condition. The larval period were 19.9 ± 2.1 days in the high temperature, long day condition(25oC, 14L : 10D). The headwidth of each developmental larval stage were 0.72 ± 0.02(1st), 1.19 ± 0.02(2nd), 1.65 ± 0.05(3rd), 2.43 ± 0.07(4th), 3.21 ± 0.12(5th). The pupal ratio was 91.6%. The pupal period were 8.8 ± 0.9 days, and the emergence rate was 92.2%.
