Abstract: Investigations on population dynamics of leaf miner, Phyllocnistis citrella infesting sweet orange were carried out under field condition during 2016-17 at Horticultural Research Station, Junagadh Agricultural University, Junagadh. The infestation of P. citrella (14.90%) started from 1st week of December, 2016 (48th SMW) and showed first peak (19.80%) during 5th week of December (52nd SMW). The infestation again increased and reached to its second peak (22.50%) during 3rd week of September (37th SMW). There was negative highly significant impact on the incidence of leaf miner due to MaxT [-0.501**] and wind speed [-0.559**] but there was no any significant linear correlation either negative or positive between incidences of leaf miner population for rest of the physical factors. However, MinT [-0.202] were negatively and relative humidity (RH1 [0.173], RH2 [0.195]) were positively whereas bright sun shine hours (BSS) [-0.100] were negatively correlated with the incidence of leaf miner population but the relationship was non-significant.
