Abstract EN

Spider mites of the family of Tetranychidae are considered as economic pests of lemon trees and cause serious damages.

The aim of this research was to study the population dynamics of citrus red mite Panonychus citri (McGregor) and citrus brown mite Eutetranychus orientalis (Klein) in three lemon orchards located in different sites in Latakia governorate (Syria), from April 2011 to March 2013.

Three to five of P.

citri population peaks were recorded in different months during the study period.

The highest densities of this species were recorded in the beginning and in the end of winter and also in the beginning of spring.

The citrus brown mite was, however, found only during autumn 2011, in particular, on September and October.

The results of the present research revealed data about changes in population dynamics of tetranychid mites and this could be useful and implemented in mite-control programs in Latakia governorate.
