ABSTRACT

Studies on the occurrence of Choreutis pariana (Clerck), the qualitative structure of the parasitoid complex of this phytophagous species, as well as the level of its parasitization, were conducted in Lublin during the 1996-1998 period. As a result of the study 1,167 larvae and pupae of apple leaf skeletonizer were collected and counted; their numbers varied according to the study sites. At the site where pesticides were regularly applied only one pupa of this species was collected. Numbers of Ch. pariana population were reduced by 11 species of parasitic hymenopterans of the Ichneumonidae and Braconidae families and the Chalcidoidea hyperfamily. The dominant species was Triclistus congener Holmgr., its contribution to the whole complex of parasitoids was over 45%. Total parasitization of apple leaf skeletonizer larvae and pupae was nearly 25%.

Key words: apple leaf skeletonizer, apple tree, Choreutis patiana, Hymenoptera – Parasitica, Lepidoptera, parasitization.
