Seasonal flight activity of sawflies (Hymenoptera, Symphyta) in submontane region of the Western Carpathians, Central Slovakia
文摘
Species representation and seasonality of adult sawflies (Symphyta) were studied using Malaise traps at three submontane study sites (Hriňová -HR, Mo?ovce -MO and ?tefanová -?T) in the Western Carpathians (Central Slovakia). One trap was operated at each study site continuously during the growing season, in MO in 1992, in HR in 1995 and in ?T in 1996. A total of 9,281 adults representing 244 species in 9 families were collected. Very rich sawfly assemblages were found. The highest species richness was in MO (181 species), followed by ?T (153 species) and HR (118 species). Pseudodineura fuscula was recorded from Slovakia for the first time. Adults were present in traps from the end of April through the first half of October. Most species occurred from the second half of May through the first half of June and finished flight activity by the end of June. Seasonal flight activities of the 16 most abundant species are analysed and discussed.
