ABSTRACT

Results presented in this paper are a continuation of studies the results of which are included in part I. They were concerning the species composition and number of leaf tortricids in apple orchards characterized by varying degrees of anthropopressure. The purpose of the studies presented in part II was to establish the structure of domination and frequency as well as the similarities of the species composition of leaf tortricids. The greatest differentiation of the domination structure of leaf tortricids was observed in the orchard without any plant protection. The group of eudominants included one species in the unprotected orchard, while in the other two, where protective treatments were performed, two species of leaf tortricids were included in each. Euconstants, which are the species of the highest frequency, were found out only in the orchard without any chemical protection. The smallest similarity of the species composition between leaf tortricids was observed between the orchard without any chemical control and the intensively protected one.

Key words: leaf tortricids, Lepidoptera, Tortricidae, apple orchards, domination, frequency structure, similarity of species composition.
