The research focused not only on the complexity of pests in grasslands but also on individual pest species; their biology and the severity of damage, with special regard to seed feeders of some frequent herd’s grass species. The observed pests are showed in two ways, both taxonomically and according to their localization on the crop that is where they cause damage. An attempt was made to present the results being easily understandable for practitioners.application/pdfpests of grassesroot feedersleave feedersseed feedersfolyóiratcikkOpen Accesshttps://doi.org/10.34101/actaagrar/62/2166Acta Agraria Debreceniensis62Acta agrar.
