Formosan Entomologist 26 (2), 109-123
Abstract: The development, survivorship, longevity, fecundity, and population parameters of the citrus psyllid, Diaphorina citri Kuwayama were studied at 16, 20, 24, 28, and 32°C on three Rutaceae plants. The measured parameters listed below are for jasmine orange, Murraya paniculata (L.) Jack; ponkan, Citrus reticulata Blanco; and kumquat, Fortunella margarita (Lour.) Swingle, respectively. The average developmental period from egg to adult varied from 56.6, 59.9, and 56.7 days at 16°C, to 15.5, 15.0, and 14.6 days at 28°C. The low temperature developmental threshold from egg to adult was 11.25, 12.75, and 13.00°C, and the cumulated effective temperature was 250 degree-days on all three plants. The survival rate also varied from 82.9, 63.3, and 77.0% at 28°C, to 9.3, 37.8, and 18.2% at 16°C. Adults reared at 16°C on all three plants and at 32°C 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 at 28°C. The cohorts reared at 28°C had the highest intrinsic rate of increase (0.254, 0.221, and 0.182); finite rate of increase (1.289, 1.247, and 1.196); net reproductive rate (319.56, 265.27, and 380.68); and shortest population doubling time (2.7, 3.1, and 3.8days); and mean generation time (22.7, 25.3, and 32.7 days). Accordingly, we concluded that the optimal temperature range for D. citri population growth was 24-28°C, and jasmine orange was the most suitable host plant among the three plants tested.
