AB Results of an analysis of dipteran pests composition and changes of their importance in agricultural, horticultural and ornamental plants during the 20th century are given. Even 89 Diptera species have been registered as pests of these plants (1.1 % of all species known in the Czech Republic). Of these ca 14 (16%) species caused regular and important and other 23 (26%) species occasional damages. The remaining 52 (58%) species are unimportant, local and sporadic pests. Only small changes (10% maximally) in the species composition of more important dipteran pests have been registered during the century.
