Citrus leaf miner is an important pest in citrus nurseries of Jiroft , Iran . In this study the population fluctuations of the insect was studied by weekly sampling and numbring of the total larvae and last larval stage percentage , in 3 different nurseries . Results showed that citrus leaf miner is emerged from the mid October and increased its population gradually to the end of fall . Because of the cold weather , the population density decreased from the mid January and reached to the minimum in the middle of February, and in the beginning of spring increased again and reached to its maximum in May. The larval percentage dynamic curves showes the pest has several generations a year in Jiroft . In laboratorial studies which leave traps used under 25°c and 70% RH conditions , average duration of egg , larval , prepupal and pupal stages were 3.65±1.37 , 8.95±1.85 and 7.5±1.91 days respectively .Meanwhile a larval parasitoide was collected from pupae and identified as Pediobius sp Key words: Citrus leaf miner , Biology , Population dynamics , Jiroft
