The sugar beet weevil (Bothynoderes punctiventris Germar 1824, Coleoptera: Curculionidae) represents the most significant sugar beet pest of the eastern Croatia's region. It is possible to control it by various methods, but the main tools for control are insecticides which often give very poor results. Due to the specific morphological structure, large feeding capacity and the small leaf area of plants at the time of insecticide application, insecticides often give very poor results and multiple treatments are implemented. Intensive use of insecticides altered the sensibility of beet weevil population and as a result there lies the possibilty that the weevils could become resistent. To avoid or at least mitigate the negative consequences of the resistance, it is neccesary to have good knowledge of pest sensibility to the insecticides. By using the pheromone traps, during the year 2019, nine population of the sugar beet weevil were collected in Osijek-Baranja county. The purpose of the adult sugar beet weevil collection was the laboratory sensibility testing on insecticides from the groups of organophosporus insecticides, piretroides and neonicotinoides. At the experiment reading, the number of the living and dead insects was counted and based on the mortality the efficacy of double dose, recommended dose and 20 % of the dose were calculated. Based on the efficeny results, the sugar beet weevil population were classified as highly sensitive, sensitive, mildly resistant, resistant and highly resistant. The most effective insecticide was chlorpyrifos and the 90 % of the population tested was sensitive and/or highly sensitive to this active substance. Less effective was insecticide lambda-cyhalothrin where 90 % of the tested population demonstrated certain level of resistancy. The weakest resistance was effectuated with acetamiprid where eight population showed high resistance and one population was resistant. The poor efficacy of the insecticide is not necessarily the consequence of the developed resistance but rather the consequence of the diminution of the sugar beet weevils sensitivity due to the specific morphological structure and their feeding capacity. To achieve satisfactory protection of the sugar beet from the sugar beet weevil, apart from permissible usage of plant protection products, the non-chemical control measures should be used.
