The research was carried out in the years 1991–1994 in agricultural landscape of medium mosaic degree in the area of Łęczyca. It covered parasitoids of the Pimplinae subfamily (Hymenoptera, Ichneumonidae), inhabiting refugium habitats such as shrubberies, field borders, roadsides and forest edges. The method used was scooping in order to catch imagos. 48 species were found, which made up 36.1% of this subfamily’s domestic fauna and 63.1% of those reported for Wielkopolska. Dominant species were Endromopoda detrita (Holmgr.) (D = 19.5%), Itoplectis maculator (F.) (D = 11.5%), I. alternans (Grav.) (D = 11.3%), Pimpla contemplator (Muell.) (D = 9.2%) and Zaglyptus multicolor (Grav.) (D = 7.1%). The greatest species diversity was reported from the forest edge (34 species), while the highest number was found in the shrubberies (268 individuals). The greatest stability of species composition was found in the shrubbery communities. The greatest species similarity between communities was reported for the shrubberies and the forest edge (SM = 53.5%). The highest similarity in terms of quantity occurred between the groups on the field border and road edge (Re = 64.5%).
