Life table parameters were calculated for the blue metallic ladybeetle, Curinus coeruleus Mulsant, fed with the Asian citrus psyllid, Diaphorina citri Kuwayama, at temperatures of 26 - 28° and 75 - 85% RH and natural photoperiod in the insectary of Faculty of Agriculture, Universiti Putra Malaysia. The development of immature stages took 19.1± 0.3 days; mated adult females lived for 34.2 ± 4.7 (range 24-39) days and produced a mean of 80.3 ± 13.6 progeny female-1 during oviposition period of 21.3 ± 1.4 days, with a sex ratio of 1:1.8 (:). The net reproductive rate (R0) was 59.1 and the capacity for increase (rc) was 0.113. The finite rate of increase (λ) was 1.29 female-1 day-1 while the intrinsic rate of natural increase (rm) was 0.116 female-1 day-1. Each female contributed 60.2 individuals to the population in a mean generation time (T) of 35.3 days. , Ibrahim, Y.B., Ibrahim, R. and Osman M.S.
