Abstract: The experiment on population dynamics of Citrus psylla, Diaphorina citri Kuwayama in relation to abiotic factor was conducted round the year during 2017-18 at ASPEE College of Horticulture and Forestry, Navsari Agricultural University, Navsari. Two peaks of citrus psylla in a year were observed. Highest psyllid population (10.23 nymphs and adults/twig/plant) were observed during 34th standard meteorological week (SMW) in a month of August while, it remained lowest (0.20 nymphs and adults/twig/plant) during 52nd SMW during winter season in a month of January. Second peak was observed during 16th SMW (8.75 nymphs and adults/twig/plant) in a month of May. Population of D. citri was highly significant and positively correlated with minimum (‘r’= 0.728**) and average temperature (‘r’= 0.675**), morning (‘r’= 0.509**), evening (‘r’= 0.620**) and average relative humidity (‘r’= 0.639**), rainfall (‘r’=0.362**) and wind velocity (‘r’= 0.449**).
