Abstract:
Проведены полевые наблюдения за цветущими растениями Alisma plantago-aquatica в Московской области. Цветок A. plantago-aquatica функционирует в течение одного светового дня в промежуток времени с 9:00 до 20:00. Белые лепестки имеют четко выраженную двуцветную контрастную окраску в ультрафиолетовом свете, которая, вероятно, служит указателем нектара для опылителей. Цветки активно посещали насекомые в период времени с 11:00 до 15:00. Среди посетителей были отмечены жесткокрылые (Coccinellidae), двукрылые (Drosophilidae, Hybotidae, Muscidae, Sepsidae, Syrphidae) и перепончатокрылые (Apidae) насекомые. Мухи-журчалки (Syrphidae) и пчелы (Apidae) в данном исследовании были отмечены в качестве наиболее массовых посетителей цветков. ...

Abstract in english:
Field observations of flowering plants of Alisma plantago-aquatica were carried out in Moscow Region (Russia). The flower of A. plantago-aquatica remains anthetic from 9:00 a.m. to 8:00 p.m. White petals of A. plantago-
aquatica show contrast pattern in UV light, with the pattern serving as a nectar guide for pollinators. The flowers were visited by insects in daytime from 11:00 a.m. to 3:00 p.m. Coleopteran (Coccinellidae), dipteran (Drosophilidae, Hybotidae, Muscidae, Sepsidae, Syrphidae) and hymenopteran (Apidae) insects were observed as flower visitors. Hoverflies (Syrphidae) and bees (Apidae) were noted as the most frequent visitors.
A large number of pollen grains of A. plantago-aquatica was found on their bodies, that proves their major role in pollination of the plant. Based on original as well as literature data, we can conclude that the hoverflies are the most stable and effective pollinators of A. plantago-aquatica in different parts of the species habitat. The bees (Apidae) were recognized as pollinators of A. plantago-aquatica for the first time in this work. An experiment on flower isolation has confirmed the studied species to be a self-compatible plant. However, the plant requires insects for the most effective cross-pollination.
