In the years 2001-2003, a study on thrips (Thysanoptera) was conducted in Lublin (south-eastern Poland). The aim of the research was to determine the species composition of the insects on selected plants from the Asteraceae family collected at sights of varying anthropopressures in Lublin. Fifteen designated sites, classified as semi-natural and anthropogenic, were located in different parts of the city. As a result of the study, the occurrence of 36 thrips species was recorded. The species dominating in the whole material were: Thrips physapus, Thrips trehernei, Thrips validus and Frankliniella intonsa. The greatest thrips species variety was characteristic of the following plant species: Hieracium umbellatum, Matricaria perforata, Taraxacum officinale, Erigeron strigosus. The research conducted shows that urban environment is quite rich in terms of thrips species diversity. The number of species caught indicates their tolerance to moderately adverse conditions in the city. The most important factor affecting the number of collected species is plant diversity. The sites of different levels of athropopressure varied both in their species composition and in the number of thrips found.
