Development, survival, and fecundity of the predator, Cybocephalus flavocapins Smith, reared on its host Aulacaspis yasumatsui Takagi, were studied at 24 degrees C, 70 +/- 10% RH, and photoperiod of 12:12 (L:D) h under laboratory conditions. Developmental periods for egg, larval, and pupal stages were 6.4, 12.1 and 14.3 d, respectively. The mean longevity of adults was 85.1 d. Raw life history data of all individuals were pooled and analyzed according to the age-stage, two-sex life table theory. The intrinsic rate of increase (r) was 0.05 d(-1) the finite rate of increase (lambda) was 1.05 d(-1), the net reproductive rate (R(0)) was 29.1 offspring, and the mean generation time (T) was 63.3 d. When we incorporated the age-stage variability of predation rate with the two-sex life table, our results indicated that the predation rates of larvae and adults were 743 eggs and 1595 scales, respectively. The net predation rate of C. flavocapitis is 1874 scales. Additionally, we compared life table results of C. flavocapitis with those of a previous life table study on Cybocephalus nipponicus because both species are currently used for the biological control of A. yasumatsui in Taiwan.
