Abstract: Investigations on biology of sweet orange leaf miner, Phyllocnistis citrella (Stainton) were carried out under laboratory condition at Department of Entomology, College of Agriculture, Junagadh Agricultural University, Junagadh during 2016-17. The average incubation period, hatching percentage, first instar, second instar, third instar, fourth instar, total larval period and pupal period of P. citrella were (2.44 ± 0.49), (74.67 ± 3.66), (1.20 ± 0.25), (1.22 ± 0.25), (2.22 ± 0.25), (2.72 ± 0.25), (7.36 ± 0.55) and (11.12 ± 0.78), respectively. The longevity of male and female moth were (4.55 ± 0.51) and (6.44 ± 0.51) days, respectively. The pre-oviposition, oviposition and post-oviposition periods of the insect were (1.18 ± 0.24), (3.22 ± 0.25) and (1.20 ± 0.25) days, respectively. The fecundity was observed to be (54.47 ± 8.89) eggs /female. Sex ratio to male: female was found to be 1: 1.2.
