The introduced Bombus terrestris has recently been naturalized in Japan and become dominant in some local communities. [] Key Result There were considerable niche overlaps in flower resource use between B. terrestris and B. hypocrita sapporoensis/B. pseudobaicalensis. Bombus terrestris also potentially competes for nest sites with B. hypocrita sapporoensis. During 3-year monitoring, B. pseudobaicalensis showed no noticeable change, but B. hypocrita sapporoensis decreased while B. terrestris increased…
Conservation ecological study of invasion of Bombus terrestris (Hymenoptera: Apidae) into a preserved area of the Notsuke Peninsula of eastern Hokkaido, Japan
Results indicate successful naturalization of B. terrestris in the native grassland vegetation and the species has potential to negatively affect native bumblebee species.
Reproductive disturbance of Japanese bumblebees by the introduced European bumblebee Bombus terrestris
The frequencies of interspecies mating between B. terrestris males and native bumblebee queens in the wild on the islands of Hokkaido and Honshu are determined by analyzing the DNA sequences of spermatozoa stored in spermathecae of native queens.
Differences in Pollen Resource Usage and Foraging Periods between the Exotic Bumblebee Bombus terrestris and the Native B. pseudobaicalensis and B. hypocrita sapporoensis in Hokkaido, Japan
Differences in plant resource usage between coexisting exotic and native bumblebee species in the Ishikari lowland region of Hokkaido suggest that these species have different flower preferences.
Examination of the visitation frequency and behavior of native and alien bumble bee species and resultant seed production in Corydalis ambigua, a native plant in Hokkaido, Japan, found introduction of alien B. terrestris may alter the native plant-pollinator mutualism.
Reproductive Interference in an Introduced Bumblebee: Polyandry may Mitigate Negative Reproductive Impact
Hybrid production in eusocial bumblebees in Japan is reviewed, by comparing introduced Bombus terrestris with native B. ignitus in Honshu and withnative B. hypocrita sapporoensis in Hokkaido, and additional new data is presented showing hybrid production between introduced B. terrestri and B. h.
Competitive effects of the exotic Bombus terrestris on native bumble bees revealed by a field removal experiment
Results show the competitive impacts of exotic B. terrestris on the queen abundance of the native species that are likely to share floral resources with B.Terrestris are shown, and the removal in 2005 affected the worker body size of neither B. Terrestris nor any native species.
Colony growth and reproductive ability of feral nests of the introduced bumblebee Bombus terrestris in northern Japan
The propagule pressure hypothesis appears to explain the probability of establishment of this invasive species, and B. terrestris may win usurpation contests against native species due to its large size, resulting in the decline of native bumblebee species.
Bombus terrestris, pollinator, invasive and pest: An assessment of problems associated with its widespread introductions for commercial purposes
It is recognized that this species is invasive, can island hop to new locations and may disturb local ecosystems, and the possible measures that must be taken to minimize the B. terrestris invasion are discussed.
Assessing the impact of the invasive buff-tailed bumblebee (Bombus terrestris) on the pollination of the native Chilean herb Mimulus luteus
Examination of the potential impact of the exotic bumblebee Bombus terrestris on the pollination service provided by the native pollinator assemblage of the herb Mimulus luteus suggests that in spite of being a quickly spreading species in Chile, B. Terrestris is still in the initial phase of invasion in this area.


Invasion Status and Potential Ecological Impacts of an Invasive Alien Bumblebee, Bombus terrestris L. (Hymenoptera: Apidae) Naturalized in Southern Hokkaido, Japan
The numbers of B. terrestris captured or observed have increased rapidly during the eight years since the evidence of its naturalization was found, and it clearly has the potential to compete with native bumblebees for floral resources and nest sites.
Abundance, body size, and morphology of bumblebees in an area where an exotic species, Bombus terrestris, has colonized in Japan
The effects of land use and bumblebee abundance on the number and body size of bumblebees collected using window traps in a lowland area in the southern Ishikari district, Hokkaido showed that dispersion from commercial B. terrestris colonies used in greenhouses positively affected the number of B. Terrestris caught by each trap.
Spatial and temporal pattern of introduced Bombus terrestris abundance in Hokkaido, Japan, and its potential impact on native bumblebees
The reduction in abundance of the native bumblebees in the sites of high B. terrestris abundance suggests the presence of interspecies competition between B. Terrestris and the nativebumblebees during the early part of the colony activity, although such reduction in B. ardens can be explained by habitat suitability.
Reproductive success of a colony of the introduced bumblebee Bombus terrestris (L.) (Hymenoptera: Apidae) in a Tasmanian National Park.
Results strongly suggest that B. terrestris is able to reproduce successfully in parts of Australia that still support almost exclusively native vegetation.

Abstract The niche breadth and overlap in nesting preferences of 15 species of bumble bees were investigated in Alberta. Some of the factors that influence the distribution of nesting sites and
Does the introduced bumblebee, Bombus terrestris (Apidae), prefer flowers of introduced or native plants in Australia?
Assessment of the ecological impacts of the European bumblebee, Bombus terrestris, in Australia must include the effects of altered pollination on recruitment rates in both introduced weeds and native plants, and reduced quantities of nectar and pollen of native plants on recruitment rate of dependent fauna.
Morphological variation in relation to flower use in bumblebees
For resource partitioning among bumblebee species, not only morphology but also other factors, such as habitat and seasonal preference, flower use, foraging behavior, and interspecific interactions are responsible.
Bumblebee commercialization will cause worldwide migration of parasitic mites
The results indicate that transportation of bumblebee colonies will cause overseas migration of parasitic mites of different origins.
Genetic differentiation of continental and island populations of Bombus terrestris (Hymenoptera: Apidae) in Europe
Microsatellite and mitochondrial DNA data call for the protection of the island populations of B. terrestris against importation of bumble bees of foreign origin which are used as crop pollinators as well as a severe bottleneck in the Canary island population.
