Potatoes are one of the most important agricultural food products, used in human diet, industry and cattle feeding. Due to its more intensive production, there is growing occurrence of pests. In addition to the potato beetle, damage to potatoes is caused by mole crickets, wireworms, white grubs (cockchafer), aphids, and potato moth. By feeding and their activity on potatoes, pests can significantly impair the quality of tubers, and destroy much of the crop. Other than pests, potatoes are affecteced by many other species, useful and indifferent species. Such species play an important role in regulating the pest population, so they are important in every crop. The aim of this study was to determine the composition, abundance and ecological characteristics of potato entomofauna at the experimental area of the Faculty of Agriculture. Entomofauna was collected using a Malaise trap. The Malaise trap is a specialized trap (tent-like appearance) for tracking primarily flying insects. Catches were inspected once a week throughout the study period (a total of 15 inspections starting from planting to potato extraction). The collected entomofauna was sorted into orders and determined to species where possible. When the number of orders was determined, their ecological characteristics, dominance and frequency were determined. During the research period, a total of 12 890 arthropod individuals were identified. The largest share of the collected fauna were members of the class Insecta (12 790 individuals). In addition, members of the class Arachnida were identified in the number of 100 individuals. The largest number of collected insect fauna consisted of individuals of order Diptera (6 469 individuals). All identified entomofauna was classified according to certain characteristics into groups of harmful, beneficial and indifferent individuals. Of the total number of identified entomofauna, the largest number consisted of harmful individuals (53 %), followed by beneficial (38 %) and indifferent individuals (9 %).
