The behavior of Phyllocnistis citrella Stainton was studied in relation to the time of oviposition and daily emergence rhythm in laboratory under controlled temperature, relative humidity and photoperiod conditions. A crepuscular and nocturnal egg-laying habit of P. citrella was recorded with approximately 95.4% eggs laid during the scotophase (10h). Out of the total eggs laid throughout 24h, about 45.4% was concentrated on the first two hours of scotophase. P. citrella adults had a synchronized emergence, with a male:female proportion of 1:1, with a consequent sexual ratio of 0.5.
