Populacija crvenog voćnog pauka (Panonychus ulmi Koch) proučavana je u veljači 2017. u integriranom voćnjaku jabuke ''Obreška'' (45°45′47″N, 16°27′04″E) metodom zimskog pregleda grana. Cilj istraživanja bio je ustanoviti brojnost zimskih jaja štetnika na pet različitih sorti jabuke ('Zlatni delišes', 'Braeburn', 'Gala', 'Idared' i 'Fuji'). Rezultati istraživanja pokazali su da se brojnost populacije crvenog voćnog pauka, na istom proizvodnom području, razlikovala ovisno o sortimentu jabuke. Brojnost populacije navedenog štetnika na sorti 'Fuji' statistički se značajno razlikovala od brojnosti populacije pauka na ostalim istraživanim sortama jabuke.

The European red mite population (Panonychus ulmi Koch) was studied in February of 2017 in IPM apple orchard ''Obreška'' (45°45′47″N 16°27′04″E) using the method of winter control of branches. The aim of the research was to determine the number of pest eggs during winter in five different apple varieties ('Golden Delicious', 'Braeburn', 'Gala', 'Idared' and 'Fuji'). The research results showed that the European red mite population differs between the varieties in the same production area. The pest population differs statistically between variety 'Fuji' and other apple varieties.
