The dramatic decline in wild populations of these five species occurred about the time that a disease outbreak was reported in populations of commercially raised western bumble bees, which were distributed for greenhouse pollination in western North America. The timing of this suggests that an escaped exotic disease organism may be the cause of this widespread loss.

One possible cause of decline in native bumble bees appears to be introduced parasites carried by bumble bees imported from Europe for greenhouse pollination. These bees frequently harbor disease organisms and their escape from greenhouses can lead to pathogen spillover into native species. Disease, notably chalkbrood (caused by the fungal pathogen, Ascosphaera aggregata), also has …

The word ‘bumblebee’ is a compound of ‘bumble’ +’bee’ –‘bumble’ meaning to hum, buzz, drone or move ineptly or flounderingly. The generic name Bombus assigned by Pierre Latreille in 1802, is derived from the latin word for a buzzing or humming sound. – angle of elevation and depression problems with solutions pdf The decline of the bumble bees and cuckoo bees (Hymenoptera: Apidae: Bombini) of Western and Central Europe Andrzej Kosior, Waldemar Celary, Paweł Olejniczak, Jan Fijał, Wiesław Kro´l

Plant native plants! Bumble bees need a stable source of nectar and pollen throughout the growing season, so plant a suite of native flowers that bloom from early spring to fall. Native plants are recommended because they are beneficial to other insects and wildlife as well.

The European honey bee (Apis mellifera) is a widespread and economically important invader long suspected to competitively suppress many native bee species. Yet the extent to which this introduced species alters native communities remains controversial, reflecting ongoing debate over the importance of resource competition in regulating pollinator populations. I experimentally tested the
The approximately 250 known species of bumble bee (genus Bombus) are found predominantly in temperate regions of the northern hemisphere. This region also contains much of the world’s human population and the most intensive agricultural regions. Probably as a result of this, many bumble bees appear to be undergoing dramatic declines in range.
Evidence of drastic decline was found in Bombus affinis, Bombus fervidus, and Bombus terricola, as well as significant decline in Bombus vagans with data suggesting it has been ecologically replaced by Bombus impatiens over time.

A recent study in New Hampshire (Tucker and Rehan 2017) discovered that Bombus terricola made up 40% of the bumble bees sampled in the White Mountain National Forest, so it seems that this bee is still doing well in wilder, higher places, even in the eastern United States.
value of honey, bees are becoming a growing generator of income, livelihood strategy and means of food security for many small-scale producers and forest dwellers in many developing countries. Clearly, the benefits that bees and other small pollinators bring us go beyond human food. Thanks to these pollinators, farm animals have diverse forage sources and hence more flexibility to adapt to an
