The adult longevity, developmental period from egg to adult, age specific survival rate (lx), age specific fecundity (mx) and maturation of ovarian eggs of Lysiphlebus japonicus ASHMEAD, which parasitizes the citrus brown aphid Toxoptera citricidus (KIRKALDY), were examined under different constant temperature conditions. Longevity decreased with temperature. The developmental period from egg to adult decreased with temperature at a range between 12℃ and 25℃. The number of mature ovarian eggs increased rapidly during 24 hr after emergence. Egg maturation was accelerated by oviposition. These traits in ovarian development resulted in the maximum value of m_x at the first day of adult life. Lifetime fecundity was higher at 25℃ than at 20℃, although adult parasitoids survived longer at 2O℃. On the basis of the results, r_m of this parasitoid at 20℃ and 25℃ were estimated to be 0.243 and 0.441,respectively. Since r_m of the parasitoid is much higher than that of alate hosts but nearly equal to that of apterous ones, the probability of successful control of T. citricidus by L. japonicus may depend on the morph and age distribution of the host in a colony at the time of the onset of parasitoid attack.
