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.
Studies on parasitoids living on larvae of leaf-miners resulted in obtaining 29 species of Braconid wasps reared from mining Lepidoptera. Out of them 23 are for the first time recorded from Poland. For each species essential information on hosts, hosts’ food plants and localities are given.
