Dissertation note: Thesis (M.Sc.) - Cairo University - Faculty of Agriculture - Department of Nematology Summary: Experiments were conducted at Menoufia governorate to study the population fluctuation of european red mite, panonychus ulmi Koch, infesting two apple cultivars; Anna and Golden dorset and their response to environmental factors (temperature and relative humidity) during 2011, 2012 and 2013 seasons. In addition, the susceptibility of two apple cultivars to mite infestation was estimated. Also, biology and life table parameters of P. ulmi were studied. The control of P. ulmi motile stages and overwintering eggs during two seasons were conducted. The results revealed the following: Mite populations reached its peak in April on golden dorset cultivar, and in May on Anna cultivars during 2012 season; while reached in May for Anna and Golden dorset cultivars during 2013 season. The peak of P. ulmi overwintering eggs found during the end of November in seasons 2012 and 2013, and the lowest numbers recorded at the end of March during two seasons, 2012 and 2013. The temperature and R.H. % positively affected population growth of P. ulmi on Apple cultivars during the two seasons. Anna cultivar was more significant susceptible to infestation than Golden dorset cultivar. It recorded 21.92 (71.3%) moving mite stages / leaf during season (2012) and 35.14 (62.9%) moving mite stages / leaf during season 2013
