In order to investigate the reproductive traits of Monochamus saltuarius, 25 pairs of adults were reared under constant conditions of 25°C, 90-100% R. H. and a photoperiod of 12L-12D. The mean oviposition ratio (number of eggs/number of oviposition marks) was 0.51. The mean lengths of preoviposition and oviposition periods were 11.2 and 41.7 days, respectively. The mean lifetime fecundity was 69.7 eggs ranging from 0 to 172 eggs. Lifetime fecundity is divided into two components, i.e. oviposition period and rate. Actually, it was highly correlated with each of these components. Oviposition period is correlated significantly with longevity while oviposition rate is with adult female size. However, there were no correlations between oviposition period and rate nor between longevity and body size. Dissection showed that the number of ovarioles in a female averaged 21.5 and did not vary in proportion to material body size.
