Anthophilous complex of alien plant Impatiens glandulifera Royle (Magnoliopsida: Balsaminaceae) in the City of Tomsk

Abstract

Impatiens glandulifera Royle is an aggressive invasive plant of Himalayan origin, one of the success factors of which is the high attractiveness to pollinators in the secondary range. In the anthophilous Impatiens complex in the city of Tomsk, 38 species of insects belonging to the orders of Hemiptera, Coleoptera, Hymenoptera, and Diptera were found. According to the number of species (84% of the species composition), as well as the number of individuals (99%), representatives of the order of Hymenoptera were dominated. Bumblebees Bombus pascuorum (Scopoli), B. hortorum (L.), and B. hypnorum (L.) and honeybee Apis mellifera (L.) were mass species. Some peculiarities of behavior of insects on the flowers of Impatiens were studied. The dynamics of abundance of insects of various ecological groups visiting Impatiens was studied in seasonal and perennial aspects.
