| Abstract | ||||
| Ecological studies on the apple rust mite Calepitrimerus baileyi Keifer was conducted for one year in an abandoned Anna apple orchard in Egypt Population dynamic of the eriophyid apple prey was affected by climatic conditions, and vertical distribution, and about 11 generations were recorded whole year. Leaves at middle levels of apple cultivar were found preferable to the mite feeding than those at the top and bottom. C. haileyi successfully developed to adult stage when reared on leaf discs from soft lateral apple branches. At 16 and 37°C, the adults began to slow down activity and then died. It was able to develop at temperature between 23-35oC and 65% R.H. Adult life cycle and longevity decreased with increasing temperature. Fecundity was highest at 35°C and averaged 23 eggs per female. Life table parameters showed that the intrinsic rate of natural increase (rm) increased with temperature increase to a maximum of 0. I 58 at 35°C. Population of C. baileyi multiplied I 5.94 times in a generation time f 17.47 days at 35°C and recorded 8.79 times in a generation time of 25.8 days at 23°C under laboratory conditions. | ||||
