Abstract

Mango varieties are liable to attack by several mite pests, such as mango bud mite, Eriophyes mangiferae (Sayed); mango leaf rust mite, Togonotus mangiferae (Keifer); mango rust mite, Metaculus mangiferae (Attiah); mango leaf coating mite, Cisaberoptus Kenyae Keifer and mango red mite, Oligonychus mangiferus (Rahman and Sapra). The predaceous mites Amblyseius swirskii A.-H., Typhlodromus mangiferus Zaher and El-Borolossy and Agistemus exsertus Gonzalez were recorded in different localities. Ecological studies on Taimour, Hindi and Zebda varieties in Giza Governorate indicated that C. kenyae and T. mangiferae have one annual peak of seasonal abundance in November, whereas for the variety Alphons the peak was in December. The population density of E. mangiferae has one annual peak in August on Taimour, in November on Hindi and in October on Alphons and Zebda.M. mangiferae has one annual peak in October on different mango varieties. The population density of O. mangiferus has one annual peak in April. The population fluctuation of mite species inhabiting Taimour mango variety in Fayoum showed that E. mangiferae and C. Kenyae have one annual peak in November. T. mangiferae has one annual peak in October, while O.mangiferus has one annual peak in April. M. magniferae was not found in Fayoum Governorate.
