A New Alfalfa Nectarophage from the Genus Timia Wiedemann (Diptera, Ulidiidae) in the Forest-Steppe of the Middle Volga Region

In the forest-steppe of the Middle Volga region, flower thrips, parasitic Hymenoptera and flies Timia abstersa (Ulidiidae) prevailed among the nectar collectors of alfalfa, accounting for 10–27, 19–47 and 21–52% of their total density, respectively. There is no any morphological adaptation for polli...

Description
Summary:In the forest-steppe of the Middle Volga region, flower thrips, parasitic Hymenoptera and flies Timia abstersa (Ulidiidae) prevailed among the nectar collectors of alfalfa, accounting for 10–27, 19–47 and 21–52% of their total density, respectively. There is no any morphological adaptation for pollination in T. abstersa . Pollen grains of alfalfa were not found on the surface of the body and in the crop of T. abstersa . They penetrate into the alfalfa flower from its side through the gap between the sail and the oar to absorb nectar. Flies of the genus Timia have short proboscis and obtain nectar in alfalfa flowers using a long special appendage of the oral disk. The highest total density of T. abstersa flies was observed in wide-row alfalfa crops of the second year of life. The alfalfa cultivar had a significant impact on the density of flies on its flowers.
