Although the existence of pollinator decline can be difficult to determine, a number of possible reasons for the theoretical concept have been proposed, such as exposure to pathogens, parasites, and pesticides; habitat destruction; climate change; market forces; intra- and interspecific competition with native and invasive species; and genetic alterations.
With the decline of both wild and domestic pollinator populations, pollination management is becoming an increasingly important part of horticulture.Factors that cause the loss of pollinators include pesticide misuse, unprofitability of beekeeping for honey, rapid transfer of pests and diseases to new areas of the globe, urban/suburban development, changing crop patterns, clearcut logging ...
Honey bee starvation is a problem for bees and beekeepers.Starvation may be caused by unfavorable weather, disease, long distance transportation or depleting food reserve. Over-harvesting of honey (and the lack of supplemental feeding) is the foremost cause for scarcity as bees are not left with enough of a honey store, though weather, disease, and disturbance can also cause problem
Apocrita (wasps, bees and ants) Hymenoptera is a large order of insects , comprising the sawflies , wasps , bees , and ants . Over 150,000 living species of Hymenoptera have been described, [ 2 ] [ 3 ] in addition to over 2,000 extinct ones. [ 4 ]
The metabolism of bees and humans is sufficiently different that bees can safely collect nectars from plants that contain compounds toxic to humans. The honey produced by bees from these toxic nectars can be poisonous if consumed by humans. In addition, natural processes can introduce toxic substances into honey produced from nontoxic nectar.
A 2018 review by the European Food Safety Authority (EFSA) concluded that most uses of neonicotinoid pesticides such as clothianidin represent a risk to wild bees and honeybees. [ 5 ] [ 6 ] Neonicotinoids have been banned for all outdoor use in the entire European Union since 2018, but has a conditional approval in the U.S. and other parts of ...
No, it's not a BBC Nature Video. It's a short video documenting the fight for survival between a bumble bee and a spider, and it's shot (and beautifully narrated) by London musician Keith John Adams.
Varroa destructor, the Varroa mite, is an external parasitic mite that attacks and feeds on honey bees and is one of the most damaging honey bee pests in the world. [2] [3] A significant mite infestation leads to the death of a honey bee colony, usually in the late autumn through early spring.
