Abstract

This work was carried out in a private farm  of citrus orchard sited at Minia Elkamh district , Sharkia governorate, Egypt, during two successive years 2013/2014 and 2014/2015. Selected citrus trees represented three varieties ( noval orange , sweet orange and mandarin). The aim of this study was to monitor population fluctuation of citrus leaf-miner, Phyllocnistis citrella Stainton (Lepidoptera: Gracillariidae) on noval orange, sweet orange and mandarin , as well as to know the effect of air temperature , relative humidity and dew point on population fluctuation of larvae. The obtained results revealed that  number of P. citrella larvae /leaf were more on noval orange than sweet orange and mandarin trees. Phyllocnistis citrella populations increased during summer months and declined during fall and winter. During the study period, 4-5 peaks of pest populations recorded on the summer shoots and 1 peak on the fall and winter shoots. Statistical analysis of the obtained data show that there are positive correlation between  population of  P. citrella  and each of temperature, relative humidity and dew point.
