This paper presents data referring to spreading ability of main aphid species from potato cultivations, for a period of two years 2005-2006. In these two experimental years the number of main aphid species was converted in unit of spreading by estimating the value of species virulence and virus infestation danger. The knowledge of the mobility capacity of the main aphid species from potato cultivations constitutes a basic element of the integrated potato pest control.
