Abstract: The present investigation entitled, “Studies on the seasonal incidence of citrus psylla (Diaphorina citri Kuw.) in Nagpur Mandarin” was conducted during Ambia bahar of 2009-10. Eight-year-old Nagpur mandarin orchard selected for imposing treatments was, planted at spacing of 6.0 m X 6.0 m at Futala farm, College of Agriculture, Nagpur. Present investigation had components like studies on seasonal incidence of citrus psylla (Diaphorina citri Kuw.). The population of citrus psylla both nymph and adult were counted on the twigs of 5 cm fresh growth of the shoot. For population dynamics of citrus psylla (Diaphorina citri Kuw.) were recorded after every 7 days during Ambia bahar of 2009-10. Weather data during 2009-10 was obtained from Meteorological observatory in College of Agriculture, Nagpur, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola. The citrus psylla abundance was very low during January but with the increase in temperature in the end of February and March, the activity of adults increased. At the same time significant increase in nymphal population was observed during February and March. It was mostly associated with the flushing cycle indicating the preference of the pest for new flush. Citrus psylla prefers warm conditions with lower humidity regime which is evident from population rise in month of February and March.
