“…The study of the dynamics of T. urticae shows that its population is sensitive to low temperatures. In Tunisia, T. urticae is active in citrus orchards, mainly in summer and autumn, from mid-June to mid-November and prefers varieties of the Clementine group (Lebdi Grissa and Khoufi, 2012). This explains the low numbers of mites during the sampling period from February to mid-May.…”

“…This is confirmed by Lebdi Grissa (2010) who mentioned that this mite is active in spring and disappears in summer in Tunisia when the temperature increases. According to Lebdi Grissa and khoufi (2012), it occurs on citrus from December to May, usually on Maltese orange varieties. In Brazil, this mite develops preferentially in the driest and coldest environmental conditions of the year (autumnwinter), which are the most favorable for its development and reproduction on citrus (Silva et al, 2012).…”

“…Tetranychidae, Tenuipalpidae, Tarsonemidae et Eriophyidae (Lebdi Grissa and Khoufi, 2012). Spider mites (Acari: Tetranychidae) are the most important phytophagous mite pests in agricultural crops worldwide (Hoy and Jeyaprakash, 2005;Walter et al, 1995).This family of mites includes five stages of development, egg, larva (with three pairs of legs), protonymph, deutonymph and adult (with four pairs of legs in the last three stages) (Kasap, 2009).…”

Phytophagous mites of the family Tetranychidae are important pests of citrus in Tunisia, reducing the quality of the product in marketing value every year. In this study, the population dynamics of Tetranychus urticae, Panonychus citri and Eutetranychus orientalis were studied in the nursery and in the field from the beginning of February until the end of May. The results showed that the population dynamics of these three mites varied with temperature. The evolution of the T. urticae population showed three peaks in February, mid-March and April. In addition, the population of E. orientalis showed four peaks in February, March, April and May. For P. citri, this mite is active in winter and spring when climatic conditions are favourable for its development. Field monitoring has shown that the fauna of predatory mites linked to these three plant pests is diverse. Three species (Neoseiulus californicus, Phytoseiulus persimilis, Euseius stipulatus) of the phytoseiid family have been identified. Given the diversification of predatory mites and their importance in the regulation of phytophagous mites, it is necessary to favor biological control by conserving these species, for which it is important to reason chemical control.
