The paper contains a short biological and taxonomical review, and methods of collecting, rearing and mounting, of parasitoids of the superfamily Ichneumonoidea infest-ing immature stages of wood-boring beetles.
Ichneumoninae communities occurring In pine cultures and canopies of pines (Pinus silvestris) are described In the consecutive stages of secondary succession of subcontinental (Peucedano-Pinetum) pine forests in Puszcza Białowieska. The parameters analysed Include species composition (136 species), structure of dominance as well as indices of species diversity, species composition similarity and dominance structure similarity. The following communities were identified: the Ichneumoninae community of the culture stage, which was markedly distinct from the others, a transitional-type community of the young stand and communities specific to older stands, where the community's core (parasitoids of the Microlepidoptera of pine) becomes stabilized - in the pole wood.
The paper provides information on the ichneumonid wasps (Hymenoptera: Ichneumonidae: Cryptinae) parasitising predatory wasps of 3 families of Aculeata (Hymenoptera: Vespidae, Pompilidae, Crabronidae) in Poland. Altogether 10 species of parasitoids have been reared from 13 species of wasps. The paper gives the first reliable information of the parasitoids of Trypoxylon minus DE BEAUMONT, 1945 (Crabronidae).
