NOTES ON THE BIOLOGY AND ECOLOGY OF LABIDOSTOMMA(ACARI PROSTIGMATA LABIDOSTOMMIDAE) IN POLAND


Abstract


The current article is a brief summary of results obtained from long-term observations (for over 67 years) ofLabidostommatidae mites in Poland. The study is based on 21,470 samples collected in different environments anddifferent locations, and each of them had a different protection status. The analysis focuses on the frequency ofoccurrence and habitat preferencesof Labidostomma luteumKramer, 1879, Labidostomma denticulatum(Schrank,1776) and Labidostomma cornutum(G. Canestrini & Fanzago, 1878) in Poland. The results of the analysis show that L.luteumwas the most frequent species found in the analyzed material, whereas specimens of L. cornutumwere very rare.Moreover, the long-term research conducted in Poland since 1950 has allowed to analyze changes in the averageabundance of the examined species in this area. The results of the analysis has revealed a decrease in the abundance ofL. luteum, which is evident especially after 1990. Finally, the comparison of the abundance of Labidostommain legallyprotected areas and those without any legal protection shows that the mites definitely prefer areas with a lowanthropogenic pressure.
