ABSTRACT

The studies were carried out in the years 1999-2001 in apple orchards in the vicinity of Lublin (Poland). The purpose of the present study was to establish the species composition of parasitoids belonging to the order Hymenoptera and Diptera, and the degree of parasitization of caterpillars and pupae of leaf tortricids (Lepidoptera: Tortricidae) in apple orchards characterized by varying intensity of plant protection. Parasitic entomofauna was the most numerous in apple orchard without any chemical control, where the degree of parasitization of larvae and pupae of leaf tortricids ranged from 7.2% to 26.4% depending on the year of studies. In this apple orchard 23 species of parasitic Hymenoptera belonging to 2 families (Ichneumonidae and Braconidae) as well as 6 species of Diptera from the family of Tachinidae were isolated. Parasitoids from the family of Ichneumonidae (Hymenoptera) turned out to be the most effective, and the dominating species was ectoparasitoid Phytodietus segmentator Grav. The most numerous among all the parasitic Diptera: Tachinidae was Eumea linearicornis Zett.

Key words: tortricids, Lepidoptera, Tortricidae, parasitoid, Ichneumonidae, Braconidae, Tachinidae, apple orchard.
