Abstract

The vast land of Iran, with its diverse climate and geographical location, is known as a suitable habitat for different types of thyme. Thyme (Thymus spp.), a plant of great nutritional and medicinal value, holds a special place among pasture plants. Consequently, investigating the factors that threaten the survival of this plant is important. Two species of thyme, T. kotschyanus (Boiss. & Hohen) and T. pubescens (Boiss. & Kotschy ex Čelak) have significant habitats in the pastures of Alborz province. In this research, pests and diseases of these two species were investigated in 14 different stations in Alborz province. The samples were collected at three time points (May, July and September) and the collected insects were taken to the laboratory for identification. The results indicated the presence of six types of pests on thyme species: Aphis serpylli, Haplothrips reuteri, Tetranychus urticae, Aeolothrips mongolicus, a mite of the genus Bryobia, and also Cuscuta spp. as a parasitic plant. Alternaria leaf spot was also detected on thyme leaves. The results of this research are reported for the first time It can be used by regional managers and stakeholders and help in the protection of Thymus species in the rangelands of Alborz province.
