Hop flea beetle (Psylliodes attenuatus Koch) is the most important pest on hop (Humulus lupulus L.) which also feeds on hemp (Cannabis sativa L. spp. sativa var. sativa) and stinging nettle (Urtica dioica L.). It was found that in vitro hop flea beetles did not feed on weeds such as lambs quarters (Chenopodium album L.), gallant soldier (Galinsoga parviflora Cav.) and redroot pigweed (Amaranthus retroflexus L.). In comparison with Aurora hop cultivar, hop flea beetles in vitro statistically significantly preferred to feed on nettle leaves and on Savinjski Golding, Cekin and Taurus hop cultivars. In comparison with Aurora, hop flea beetles showed statistically significantly smaller preference to Bialobrzeskie strain hemp plants and Apolon, Blisk, Magnum hop cultivars and Japanese and Slovenian wild hops.
