ln the years 1998-2001 the occurrence of eriophyoid mites on grasses was studied in Poland. The survey showed that the grass-inhabiting eriophyoid fauna is represented in Poland by six genera and 29 species. Nine of the species have been described as new to science, i.e. Aceria absentia, Aceria erecti, Aceria flexuosae, Aceria glomerivagrans, Aceria nardusi, Aceria stipaespinulata, Aculodes holcusi, Aculodes multitricavus and Jaranasia sesleriae; and four have been recorded in Poland for the first time, i.e. Aceria anthocoptes (Nalepa), Aceria aculiformia Sukhareva, Aceria calamagrostis Sukhareva, Aceria taurica Mitrofanov et Sharonov. The known species have been redescribed and supplemented. Males, nymphs and larvae of Aceria aculiformia, Aceria eximia Sukhareva, Aceria tosichella Keifer, Abacarus acutatus Sukhareva, Abacarus hystrix (Nalepa), Aculodes dubius (Nalepa), Aculodes mckenziei (Keifer) have been described for the first time. A key to determination of females of grass-inhabiting Eriophyoidea in Poland has been given. The information about host plants, feeding habits, distributions and plant injuries caused by mites have been provided. To determine the degree of mite infestation on grasses the values of its prevalence, intensity and density have been calculated. On the basis of mite infestation, classes of mite specificity (specialists l, specialists ll and generalists) and classes of hosts (accidental, accessory and specific) have been adopted. Grass-inhabiting eriophyoids in Poland may have host specificity varying from narrow to extreme. About 60% of species are specialists l limited to one host species, about 20% are either specialists ll which live on two or three host species and generalists which have broad host range. The most widely distributed and abundant eriophyoids on grasses in Poland were: Abacarus hystrix, Aculodes mckenziei and A. dubius.
