Abstract

Thysanoptera species were collected from Stellaria media in autumn, winter and spring in different biotopes, in Hungary. The total number of the sampled specimens was 5121. 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. S. media provides a suitable site for winter refuge, and an alternative food source for a few species, which hibernate under bark, fallen leaves and dry grass as well as in the soil, leaving their winter quarters move and accu­mulate temporarily on this plant. Specimens of T. tabaci capable of harbouring tomato spotted wilt virus occurred in every investigated biotopes.
