Background. Of great importance for bumblebees is the availability of a food base in two significant periods of life: at the beginning of flight activity after leaving wintering and at the end of flight activity in the period before wintering. The purpose of the work was to analyze the interacting groups of the interspecific association of bumblebees of Omsk forest-steppe at the beginning of flight activity after leaving wintering. Materials and methods. Field determinants are used in the work; the taxonomy of bumblebee species is given by Williams P. Results. Taking into account the timing of summer of each species included in the interspecific association, we identified the period of the beginning of the flight activity of bumblebees – from the 1st decade of May to the 3rd decade of June. Depending on weather conditions during the period of leaving the winter, the timing of flight activity may shift. Conclusions. At the beginning of the flight activity of bumblebees of the interspecific association of the central forest-steppe of the Omsk region from the 1st decade of May to the 3rd decade of June, the main forage plants are 28 species from nine families. The interspecific association of the central forest-steppe of the Omsk region at the beginning of flight activity, after leaving wintering, consists of several interacting groups, which at certain periods are formed from a different number of bumblebees. |
