Sažetak
European red mite (Panonychus ulmi Koch) is one of the most common apple pests. Weather conditions, as well as pesticides, affect red mite development. This mite also shows preferences to particular apple varieties. This research was conducted in Zadar County (Croatia) during three years (2016 - 2018) using the winter control of branches method. In 2016 the highest average number of overwintering eggs was found on Gala (338,33), Cripps Pink (241,33) and Red Elstar (247) until on Golden Delicious and Summer Red lower number was observed. In 2017 the highest abundance was noticed on Cripps Pink (40) and Golden Delicious (24) but still low compared with the previous year. In 2018 the highest number of overwintering eggs was found on Granny Smith (20). Number of overwintering eggs on Golden Delicious and Summer Red was similar in 2016, 2017 and 2018. During this research, no one variety showed a critical number of overwintering eggs.
