Growth and reproduction were compared between Toxoptera citricidus and Aphis citricola. Comparisons were also made among the first generation, which consisted of fundatrices, the second generation, and the subsequent summer generations of each species. In both species, fundatrices developed more slowly than second and subsequent generation individuals. The fastest development took place in the summer generations in T. citricidus and the second generation in A. citricola. Capacity for increase, net reproductive rate and the maximum fecundity were largest in the second generation in both species. The difference in maximum fecundity between the summer generations and the first two generations in A. citricola was less than that of the same category in T. citricidus. Net reproductive rate of T. citricidus was usually larger than that of A. citricola. Reproductive schedule as displayed by the distribution of age specific fecundity changed with temperature and among generations. As for cohort generation time, the second generation was intermediate between the first and summer generations in T. citricidus, while in A. citricola the first and second generations were nearly the same.
