Abstract
The development, survivorship, longevity, fecundity, and population parameters of the citrus psyllid, Diaphorina citri Kuwayama, were studied at 160C, 200C, 240C, 280C, and 320C on three Rutaceae plants viz. jasmine orange, Murraya paniculata (L.) Jack; ponkan, Citrus reticulata Blanco; and kumquat, Fortunella margarita (Lour.) Swingle. The average developmental period from egg to adult on jasmine orange, ponkan, and kumquat varied from 56.6, 59.9, and 56.7 days at 160C to 15.5, 15.0, and 14.6 days at 280C, respectively. The low temperature developmental thresholds from egg to adult, was 11.25, 12.75, and 13.000C on the respective plant, and the cumulated effective temperature was 250 degree-days on three plants. The survival rate also varied from 82.9, 63.3, and 77.0% at 280C to 9.3, 37.8, and 18.2% at 160C, respectively. Adults reared at 160C on three plants and 320C on ponkan failed to survive and reproduce. The mean longevity of females decreased with increasing temperature. A female on average laid 616.5, 523.5, and 795.5 eggs on the respective plant at 280C. The cohorts reared at 280C had the highest intrinsic rate of increase, being 0.254, 0.221, and 0.182, the finite rate of increase, being 1.289, 1.247, and 1.196, and the net reproductive rate, being 319.56, 265.27, and 380.68; and the shortest population doubling time, being 2.7, 3.1, and 3.8 days; and the mean generation time, being 22.7, 25.3, and 32.7 days on the respective plant. Accordingly, we concluded that the optimal temperature range for D. citri population growth was 24-280C, and jasmine orange was its most suitable host plant among the three plants tested.
