In this work the authors give a list of mites (Acari, Mesostigmata) which have so far been found in the area of the Pieniny Mountains. This list was made up on the basis of their own studies, but those studies that had previously been conducted on the subject were also taken into consideration.
2165 specimens, representing 54 species in 12 families were identified. The most common species were: Veigaia nerriorensis, Pergamasus runcatellus, P. parvulus, Geholaspis longispinosus, Macrocheles tardus, Pergamasus brevicomis and Pachylaelaps vexillifer. The geographical distributions and ecological occurrence of all the species were compared.
The Uropodina of Polish pine forest were investigated. 20 species of Uropodina recorded for which the faunistic and ecologically analisis has been done.
Communities of mites (Acarida) were investigated on 6 plots representing 3 different types of the urban green in Katowice (housing estate lawns, park lawns and park forest). The mite fauna of the urban green was characterized by a lower number of individuals and a higher number of species as compared with the fauna of suburban and natural habitats. The share in the communities of predatory Gamasida was much higher in the urban habitats, unlike Oribatida. Avery low frequency of occurrence of species was characteristic of the investigated fauna. The species diversity appear to be a poor indicator of the structure of a mite community. The dominant species in urban green were discussed together with their morpho-ecological features.
There were investigated plastic strips with active ingredient flumethrin: Bayvarol-Strips (R). There were used 4 strips for a treatment. They were placed between combs of honey bee colony. The mean effectiveness of te medication was 95,6%. Bayvarol-Strips (R) were harmless for bees.
Studies were carried out on the occurrence of Uropodina in the Roztocze and Roztoczański National Park. In studied area there were recorded 44 species of Uropodina. The characteristics of the Uropodina mites of the 22 types of habitats were presented.
