Abstract

The population fluctuation of Panonychus citri was studied during two successive years on three citrus species at Giza Governorate namely: Lemon (Citrus limon L.), Sweet orange; Navel orange (Citrus sendonensis L.). The obtained results recorded negative correlation between number of mites and average temperature and positive correlation between mite population and average relative humidity. Moreover, the citrus red mite, P. citri has one annual peak of year abundance in March on Lemon trees, while on naval orange and sweet orange, the annual peak occurred in April during two successive years.
