The mango spider mite, Oligonychus mangiferus (Rahman and Sapra) (Tetranychidae) and the mango bud mite, Aceria mangiferae Sayed (Eriophyidae) are serious pests of mango orchards in Egypt. The population dynamics of both species were studied on two mango cultivars (Zebda and Taimoor) under the natural climatic conditions of Assiut Governorate. Also, an annotated list was provided for the mite fauna inhabiting mango orchards during the present study and in previous Egyptian literature. The results showed that the population dynamics of both mite pests were affected by the ambient climatic conditions (temperature and relative humidity) and mango cultivar. The peak population of O. mangiferus was reported in October-November on leaves of both cultivars, while A. mangiferae was found regularly at almost all examined buds throughout the year. The checklist reported on 67 species belonging to 30 families and 52 genera. The predatory mites, Eucheyletia sp., Lepidocheyla gracilis Volgin (Cheyletidae) and Hemisarcoptes coccophagus Meyer (Hemisarcoptidae) were recorded for the first time in Egypt. Interestingly, the family Phytoseiidae represented the largest diversity of mites reported herein, with 10 species records. We anticipate that the results reported in the current study may encourage the establishment of control programs for these pests using phytoseiid mites.
