摘要： Determining the best ratio of females to males of an insect's natural enemy is important for maximising population increase and promoting population establishment of a natural enemy. In this study, copulation behaviour, fecundity, progeny fitness and rate of population increase for the flea beetle, Agasicles hygrophila Selman & Vogt (Coleoptera: Chrysomelidae), were compared at different female percentage treatments (i.e., 80%, 66.7%, 50%, 33.3% and 20% females). The results showed that the copulation frequency and duration in males decreased, whereas those in females increased as the number of males increased. At 20%, 33.3% and 66.7% females, the rates of population increase were 3.4-, 2.17- and 0.79-fold higher than that at 50% females. Females at 20% and 33.3% were found to be optimal for mass rearing of the beetle
