Panonychus ulmi is widely distributed in apple and vineyards worldwide. In Brazil, the first damages were observed in apple orchard and later in grapevine. The aim of this study was to evaluate feeding preference and biological traits of P. ulmi on different grapevine varieties (BRS Vitória, Merlot and Concord) and apple (Fuji) under laboratory conditions. The food preference experiment did not reveal any significant differences, but P. ulmi presented the lowest rate of oviposition in the Concord varietal, demonstrating an oviposition preference in V. vinifera varietals and general preference for apple. Mortality was significantly different between varieties, with the lowest mortality on apple and higher oviposition rate in this host. Higher viability occurred on Merlot and apple. Feeding preference studies are scarce, considering phytophagous mites and grape varieties, although they are important in the development of pest control strategies.
