Plant viruses, and aphids as their vectors, are limiting factors in sugar beet production. Viral plant diseases are currently impossible to treat but knowing the flight patterns of aphids can help in reducing the number of potential virus vectors. Monitoring of aphid flight activities in sugar beet fields was done using yellow water traps from April to the end of November. During the two years of investigation, a total of 5514 specimens from 75 different taxa were collected. The highest number of individuals was recorded at the end of May/beginning of June at all localities. This is the period when sugar beet develops intensively, so the risk of virus infection is the highest. The most numerous species were Aphis fabae Scopoli, Aphis spiraecola Patch., Phyllaphis fagi (L.), Myzus persicae (Sulzer), Rhopalosiphum padi (L.), Sitobion avenae (Fabr.), Acyrthosiphon pisum (Haris) and Therioaphis trifolii (Monell). The most important vectors are A. fabae, A. spiraecola and M. persicae. Aphis fabae is a species that feeds on sugar beet and causes significant damage both by feeding and by its vector activity. Myzus persicae was the most abundant in autumn, A. spiraecola was present throughout the whole flight-monitoring period. Among the caught aphids, twelve species alien to Europe were collected.
