Abstract

The brown mite, Scheuten thrives on sweet cherry, sour cherry and plum orchards of Hamedan in the western region of Iran. Development and fecundity of this mite was studied on sweet cherry at nine constant temperatures (15, 17.5, 20, 22.5, 25, 27.5, 30, 32.5 and 35 °C), 60 ± 5% relative humidity and a photoperiod of 16:8 h (light:dark). The developmental time from egg to adult ranged from 43.4 ± 0.63 days at 15 °C to 14.5 ± 0.37 days at 32.5 °C. The average longevity of adult females was 14.0 ± 0.88 days at 15 °C to 6.5 ± 0.67 days at 32.5 °C. The highest and lowest mean number of eggs laid by a female during life time was 13.8 ± 1.07 and 4.4 ± 0.88 at 20 and 32.5 °C, respectively. These results may be used to predict development and population fluctuations.
