Studies were conducted in the temperate forests of the European part of Russia (territory of the Republic of Mordovia). Beer traps with bait made of beer and sugar were used for the studies. Three plots were selected for the study, which differed in the composition of plants at the edges, adjacent open ecosystems and types of forest ecosystems. The forest was adjacent to this open ecosystem and there was no transition zone of shrubs. Eight traps were used in each plot (1,2 - edge-below, 3,4 - edge-above, 5,6 - forest interior-below, 7,8 - forest interiorabove). They were located 1.5 m (further named as "below" traps) and 7.5 m (further named as "above" traps) from the ground level. During the experiments, 52306 specimens from 28 families of Diptera were captured. In terms of total abundance, representatives of 25 families were present in the lower traps and species from 27 families were present in the upper traps. The general pattern was the highest abundance of Diptera at the edges in all plots. Nine families (Tipulidae, Anisopodidae, Lonchaeidae, Milichiidae, Drosophilidae, Anthomyiidae, Fanniidae, Muscidae, Calliphoridae) accounted for 93.3% of all Diptera abundance in all plots. The families Tipulidae, and Drosophilidae were the most abundant in lower traps within forest ecosystems. The families Lonchaeidae, Milichiidae, Anthomyiidae, Fanniidae, and Muscidae were most abundant in upper traps at the edges of forests. The families Anisopodidae, Calliphoridae were the most abundant in the lower down edges. [ABSTRACT FROM AUTHOR] |
