Fig trees are one of the most economically important fruit crops in Egypt. The current research aimed to study the population dynamics and chemical control of some phytophagous mites associated with fig orchards in Tanan village, Qalubia governorate, Egypt, from Mar. 2022 to Feb. 2024. The results showed the incidence of 12 mite species belonging to 12 genera in eight families. Koch (Tetranychidae), (Cotté) and Meyer & Ueckermann (Eriophyidae), as well as Keifer (Diptilomiopidae) have become as important phytophagous mites on “Sultani” fig. The predatory mites, Athias-Henriot and Ribaga (Phytoseiidae), and Gonzalez (Stigmaeidae) are the most commonly associated with phytophagous mites in fig trees. The phytophagous mites, , , , and have two annual peaks on fig leaves, with in late June and mid-Oct., in June and early Oct., and in mid-May and mid-Nov., while in mid-June and mid-Oct. The correlation coefficient between phytophagous mites and the weather factors showed a significant positive correlation with temperature but an insignificant correlation with relative humidity. Two sprays of the six acaricides, vertimec, solo, danisaraba, ceflo, magnifico, and envidor were used to control the previous phytophagous mites in fig orchards. All tested acaricides recorded a high mean reduction percentage after two sprays during the 2023 season. Spiromesifen and abamectin had the highest reduction percentage among all mite pests.
