During 2018, we investigated the efficacy of insecticides with different modes of action in the control of green peach aphid (Myzus persicae Sulzer) by performing field trial. The experiment was performed in nectarine orchard at locality Petrijevo (municipality Smederevo, Serbia), according with the standard EPPO method. Results of the field trial indicate good efficacy of insecticides from the group of neonicotinoids in the control of green peach aphid at this locality. The efficacy of imidacloprid was 95.92 - 98.38%, while the efficacy of acetamiprid was slightly lower but still good (94.57 - 97.41%). Methomyl, compound from the carbamate group, had poor efficacy (60.51% - 81.99%), as well as chlorpyrifos, a representative of the organophosphate group (2,49% - 34.02%). Insecticides from the pyrethroide group also showed poor efficacy at this locality. Thus, the efficacy of bifenthrin was 44.38% - 50.64%, whereas the lambda - cyhalothrin had an even lower efficacy in the control of M. persicae (28.44% - 42.88%).
