چکیده:

The brown mite Bryobia rubrioculus Scheuten is spreaded around the world and reported on different planthosts. This mite activates on some fruit trees. In the recent years this mite has many aspects of the economicimportance specially in country west areas such as Hamedan, the study conducted at 9 constant temperatures in the lab (15, 17.5, 20, 22.5, 25, 27.5, 30, 32.5, 35) (±۰٫۵), (L:D) (16:8), Rh(60±۵)% on leaf disc. The results showed the intrinsic rate of increase (rm) at (15-20) ºC was between 0.0414 – 0.0673 /day, but reduced from20 ºC to 32.5 ºC. The most amount of population parameters obtained for net reproductive rate (R0) and the intrinsic rate of increase (rm) at 20 ºC (6.58±۰٫۵۶ and 0.067±۰٫۰۰۳). Also the lowest amount of doubling time(DT) (10.67±۰٫۳۹ days) was at that temperature. Therefore, the 20 ºC can be the optimum temperature for the brown mite on sweet cherry. The results is applied to IPM (Integrated Pest Management) and used of the natural enemies for this pest on fruit trees under environmental conditions.
