We realized a faunistic research of praticol insects at four meadow study sites in the mountain regions Babia hora and Pilsko (Horná Orava Protected Landscape Area). The etomological material was collected by slipping of herbal layer of the studied grasslands during the vegetation period 2018 (from May to October). Total recorded insects represented 1907 specimens. belonging to 10 generas and 50 families. Coleoptera (44 %), Hemiptera (24 %) and Diptera (16 %) were the dominant generas. In the region of Babia hora, the abundance and species richness of entomocenoses were lower in the meadow habitat affected by tourism (Site A: N = 381 ex., S = 71 sp.) in comparing with the agriculturally used meadow - mowed meadow (Site B: N = 563 ex., S = 109 sp.). Similar result is also recorded in the region of Pilsko, where the study site affected by tourism shows a lower number of insects and species richness (Site C: N = 386 ex., S = 48 sp.) in comparing with the agriculturally used meadow locality without tourism influence (Site D: N = 577 ex., S = 63 sp.). The seasonal dynamic of Coleoptera on study sites is also presented. Diversity is evaluated by Shannon - Wiener Diversity Index (Babia hora: dA = 2,726 vs. dB = 3,361 and Pilsko: dc = 2,347 vs. dD = 2,612) and their values are considerable high, which points to the ecological stability of the compared meadow ecosystems.
