The food preference of Eurydema ornatum (L.) (Heteroptera: Pentatomidae) was determined in six cultivated plants belonging to Cruciferae; white cabbage, broccoli, cauliflower, brussels sprouts, red cabbage and radish. Experiments were conducted at 25 plus minus 1 degree C, 55 plus minus 5% relative humidity with a 16 h light: 8 h dark photoperiod in the laboratory. The results indicated that significant difference was seen in nympal stage, adult stage and together with nympal and adult stages. While the most preferred plant was found as white cabbage, the lowest preference was seen in Brussels sprouts in nympal stage. On the other hand, while white cabbage and cauliflower were found the most preferred plants, the lowest preference was seen in Brussels sprouts in adult stage. When the nympal and adult trials was evaluated together with, white cabbage was found the most preferred plant and Brussels sprouts was found the lowest preferred plant.
