In the years 1999-2000 the occurrence of eriophyoids on grasses was studied in the Wielkopolska region. 9 eriophyoid species were recognized on 29 grass species. Eriophyoids were present in 38 percent examined plant samples. The most often infested were Agropyron repens and Lolium perenne and the least Arrhenatherum elatus, Abacarus hystrix and Aculodes mckenziei were dominating eriophyoid species. The intensity of occurrence varied and was related to the eriophyoid species and the host plant. Feeding of some eriophyoids species caused either matting or browning or twisting of the leaf blades
