Abstract
Bumblebees, as pollinators of many plants, are the most important ecological component of natural and natural-anthropogenic ecosystems. The purpose of the research is to identify the structure of the food reserve of bumblebees living in the forest biotopes of the Leningrad province, as well as to study the dynamics of its changes during the period of bumblebee activity from April to September. The food reserve of bumblebees of forest ecosystem of the studied area of the Leningrad province includes 81 species of plants belonging to 23 families, which is 43% of the total diversity of honey-bearing and pollen-bearing plants of the Leningrad province. According to the timing of flowering and the inclusion of species in the structure of the food supply, four periods can be distinguished: spring (April – May), early summer (June), summer (July – August) and autumn (September). The spring period is characterized by a low species diversity of the forage base. Early summer – a sharp increase in the species diversity of the food supply. Summer – stabilization at the level of maximum values. Autumn – a sharp drop in the species diversity of forage plants. Analysis of the structure of the bumblebee food supply shows that at the beginning of the first period (April), the core of the food supply are plants of Salicaceae. Starting from the second decade of May, the structure of the fodder base is being restructured, as a result of which a single dominant is not allocated. In June (the second period), Fabaceae become the nucleus, and in the third and fourth periods they are replaced by Asteraceae. The greatest species diversity is characterized by Asteraceae – 19 species. The second group (9 – 10 species) consists of Fabaceae and Lamiaceae. The third group (7 – 4 species) – Scrophulariaceae, Salicaceae, Rosaceae, Apiceae. 16 plant families are represented in the food reserve by 1 – 2 species. Thus, a group of 7 plant families accounts for 74% of the species diversity of plants in the food reserve of bumblebees.
