New faunistic data on leaf-mining species of Lepidoptera from central Poland are provided. Eight species are new for Lodz province: Stigmella alnetella, Tischeria decidua, Caloptilia betulicola, Leucospilapteryx omissella, Phyllonorycter issikii, Phyllonorycter platani, Phyllonorycter robiniella, Leucoptera malifoliella.

Leaf miner moths on common hazel in urban habitats and in the forest and on cultivated hazel on productive plantation without chemical treatments were studied regarding the composition of their species and structure of their abundance in 2000–2002. The presence of six microlepidopteran species belonging to 3 families was shown: Nepticulidae (2 species), Gracillariidae (3) and Coleophoridae (1). The main factor affecting the occurrence of microlepidopteran species feeding on hazelnut with respect only to quantitative composition, was the type of environment with variable degree of anthropogenic. Species from Phyllonorycter genus were dominant on cultivated hazel and on common hazel growing in urban habitats, while on hazel growing in the forest Phyllonorycter nicellii and Stigmella microtheriella species were dominant. The best conditions for development of mining Lepidoptera were on cultivated hazelnut plantation, where their abundance was significantly higher compared with common hazelnut.

The study was performed during two growing seasons (2002–2003). The experimental material was collected from hazel shrubs growing in three sites in Lublin. During the laboratory rearing that involved 1 922 larvae and pupae of 5 species of mining moths [Stigmella microtheriella (Stt.), Phyllonorycter coryli Nic., Phyllonorycter nicellii (Stt.), Parornix devoniella (Stt.), Coleophora serratella (L.)], 280 imagines of parasitoids were obtained. The most numerous group was Chalcidoidea f. Eulophidae – 93.2%, other species belonged to Braconidae –6.8%. The total parasitization of mining-moth larvae and pupae was 14.6%. The ratio of parasitization on mining moths for a particular complex of parasitoids oscillated from 7.8% to 41.2%. The highest parasitization ratio of mining moths was observed for the site II (16.3%) situated near a busy road.
