NATURAL REGULATION OF THE APPLE LEAF-MINING MOTH POPULATIONS IN DIFFERENT TYPES OF HABITATS
Journal Title: ELECTRONIC JOURNAL OF POLISH AGRICULTURAL UNIVERSITIES - Year 2009, Vol 12, Issue 3
Abstract
The species composition of parasitoids and the degree of parasitization of leaf-mining moths feeding apple trees in habitats of different anthropogenic pressure was studied during three growing seasons. Twenty six species of parasitoid hymenopterans from the superfamily Chalcidoidea and the families: Braconidae and Ichneumonidae were obtained. Parasitoids from the family Eulophidae played the greatest role in parasitization of leaf-mining moths. At untreated sites, hymenopterans parasitisized 15.5% of hosts, while at the treated orchard, parasitization rate was 5.2%. Among founded parasitoids, the highest ecological tolerance showed Cirrospilus vittatus and Sympiesis gregori (obtained only from the treated orchards) and Sympies sericeicornis, Pnigalio pectinicornis and Apanteles xanthostigma occurring in both studied types of habitats.
