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.
The rearing of 3864 larvae and 1005 pupae of 10 apple leafminers species was conducted in 1996-1998. Parasitoids were obtained from 7 of 10 species of moths involved in the rear. As a result 2092 imagines of parasitoids were obtained belonging to 35 species from 5 families and 9 subfamilies of terebrantia (Hymenoptera - Parasitica). Achrysocharoides latreillei CURT., Cirrospilus diallus WALK., Sympiesis gregori BOUCEK, Elachertus inunctus NEES and Triclistus spilacularis THOMS. are reported as parasitoids of leaf-mining moths occurring on apple trees for the first time.
The aim of presented investigation was to determine the composition of scale insects species and intensity of their occurrence on some greenhouse’s ornamental plants. The investigations were carried out in the greenhouse of Maria Curie Skłodowska Botanical Garden in Lublin in years 2002–2004. Eight species belonging to seven botanical families were observed: Abutilon striatum cv. Thomsoni, Cyrtomium falcatum Presl., Dizygotheca elegantissima (Veitch), Hedera helix L., Hypoestes phyllostachya Presl., Nerium oleander L., Passiflora guadrangularia L., Ruscus aculeatus L. The quantitative analysis of the studied material was performed making use of the following ecological indicators: number and density. Identification of the scale insects species was performed on the basis of microscope slides. Three species of the scale insects belonging to three families were observed on ornamental plants: Pseudococcidae [Pseudococcus maritimus (Ehrh.)], Coccidae [Saissetia coffeae (Walker)] and Diaspididae (Aspidiotus nerii Bouchè). The scale insects were noted on all species of studied plants. Observed scale insects are typical polyphagous and all of them are considered as harmful pests in greenhouses. Among scale insects inhabiting this group of plants distinctly numerous on particular host plants were S. coffea and A. nerii. On the studied plants scale insects were stated at four degree of density.
Ten hymenopteran species of the family Ichneumonidae (2 species) and superfamily Chalcidoidea (8 species) had been reared from cocoons of Callisto denticulella (THNBG.). Such parasitoids as Gelis areator (PANZ.), Chrysocharis pentheus WALK., Pedobius saulius WALK., Dibrachys cavus WALK., Eupelmus fulvipes FÖRSTER, Eupelmus urozonus DALMAN, Eurytoma goidanichi BOUCEK and Parablastothrix montana ERDÖS had not been reported from the host before. E. fulvipes, E. goidanichi and P. montana are species new to Poland.
49 species belonging to the families Nymphalidae, Lycaenidae, Pieridae, Hesperiidae and Papilionidae were found in „Uroczysko Lipnik” and made about 28% of the total number of Rhopalocera species ever reported from Poland. In the study area found to be present Lycaena dispar. It is the only one protected species of Rhopalocera occurring in the study area.
