The ovipositional characteristics of the endangered species Prosopocoilus astacoides blanchardi was investigated for indoor mass-rearing. This insect required 3 weeks or more for mating after emergence when introduced at the 1:1 ratio of male to female. Among temperatures studied at 16, 20, 24, 28, and 32℃, the pre-ovipositional period of P. astacoides blanchardi was longest at 16℃ with an average of 109 days after emergence, while it was shortest at 32℃ with an average of 59.4 days. The number of eggs laid at 24℃ was highest with an average of 40.6 per female. The average lifespan of adults at 16℃ was 208.8 days for males and 263.9 days for females, while at 32℃ 96.1 days for males and 130.3 days for females. The number of laid eggs was dependent on insect rearing chamber size. The oviposition-trees did not significantly (P > 0.05) affect the number of laid eggs and ovipositional period. The results of this study could be used as rearing data for the restoration and mass propagation of the endangered species P. astacoides blanchardi.
