Bumble bees are among the most significant insect pollinators of many entomophilous plants. Therefore they have an important place in the terrestrial ecosystems of the boreal and subarctic zones. The populations of many species of Apoidea including bumble bees are strongly influenced by different anthropogenic factors, the most important of which are the destruction of habitat and food resources, chemical pollution of the environment, recreational pressure on biotopes and transport (Bogatyrev, 1985; Williams, 1986; Efremova, 1986; Kosior & Nosek, 1987; Butovskiy, 1989; Donath, 1989). The Moscow region has been chosen for our investigations as a model territory for the analysis of bumble bee population changes owing to urbanization and is characterized by strong anthropogenic influences upon all ecosystem components and also by the wide variety of landscapes and biotopes.
