ABSTRACT: Sour cherry is considered as an economically important fruit tree, providing a valuable and delicious fruit across the world. Recently, large numbers of the brown mite,Bryobia rubrioculusScheuten (Acari: Tetranychidae) attacked sour cherry or-chards of Hamedan, Iran. In 2013, biological experiments were conducted on two sour cherry cultivars under constant conditions (26 ± 0.5)ºC, (L:D) (16:8), and (60 ± 5) RH. Pre-imaginal development time was 22.4 and 24.89 days, gross fecundity rate was 11.59 and 9.87 eggs, and r m assumed to be (was determined) 0.0164 and 0.0048 day -1 respectively. Few biological parameters of the brown mite had correlation with physiological aspects of the sour cherry. The results of this research provide important data about brown mite for integrate pest management
