Abstract
To estimate the generation period of citrus psyllid, Diaphorina citri Kuwayama（Hemiptera: Liviidae）, we examined the temperature-dependent development of the insect during the pre-oviposition period and determined the developmental zero and effective accumulative temperature for development in a laboratory. Adults were reared at 15.9, 17.4, 20.1, 22.3, 25.0, 27.4, 29.9, and 32.5°C on new leaves of orange jasmine, Murraya paniculata（L.）Jack var. exotica（L.）C. C. Huang. The average pre-oviposition period at each temperature was 52.5, 26.9, 14.8, 9.6, 7.9, 6.0, 5.3 and 3.0 days, respectively. The mortality rate was highest at 32.5°C. Based on the results from 17.4 to 29.9°C, the developmental zero and effective accumulative temperature for the development of D. citri were 14.39°C and 80.45 s degree-days, respectively, during the pre-oviposition period.
