The most frequent species were (in order of frequency): Thrips tabaci, T. atratus, Frankliniella intonsa, Aptinothrips rufus, T. minutissimus, T. nigropilosus and Anaphothrips obscurus. The number of species as well as the composition of the species occurring on S. media depends on the characteristics of biotopes. The number of species considerably increased in spring from 15 to 43. Among them seven species occurred from autumn through winter till spring.
