Three Seasons of Bees and Other Natural and Unnatural Things
Contents:
Evidence from Japan [] and South America [] indicates bumblebees can escape and naturalise in new environments, causing damage to native pollinators. Greater use of native pollinators, such as Bombus ignitus in China and Japan, has occurred as a result.

In Canada and Sweden it has been shown that growing a mosaic of different crops encourages bumblebees and provides higher yields than does a monoculture of oilseed rape, despite the fact that the bees were attracted to the crop. Bumblebee species are declining in Europe, North America, and Asia due to a number of factors, including land-use change that reduces their food plants.
In North America, pathogens are possibly having a stronger negative effect especially for the subgenus Bombus. Small farms depended on horses to pull implements and carts. The horses were fed on clover and hay, both of which were permanently grown on a typical farm. Little artificial fertiliser was used. Farms thus provided flowering clover and flower-rich meadows, favouring bumblebees. Mechanisation removed the need for horses and most of the clover; artificial fertilisers encouraged the growth of taller grasses, outcompeting the meadow flowers.
Most of the flowers, and the bumblebees that fed on them, disappeared from Britain by the early s. The last native British short-haired bumblebee was captured near Dungeness in The bees are directly exposed to the chemicals in two ways: The species Bombus hortorum in particular has been found to be impacted by the pesticides; their brood development has been reduced and their memory has been negatively affected.
Additionally, pesticide use negatively impacts colony development and size. Bumblebees are in danger in many developed countries due to habitat destruction and collateral pesticide damage. The European Food Safety Authority ruled that three neonicotinoid pesticides clothianidin , imidacloprid , and thiamethoxam presented a high risk for bees. The Bumblebee Conservation Trust considers this evidence of reduced brain function "particularly alarming given that bumblebees rely upon their intelligence to go about their daily tasks.
Bee colonies that had been affected by the pesticide released more foragers and collected more pollen than bees who had not been dosed with neonicotinoid.

Of 19 species of native nestmaking bumblebees and six species of cuckoo bumblebees formerly widespread in Britain , [] three have been extirpated, [] [] eight are in serious decline , and only six remain widespread. Some bumblebees native to North America are also vanishing, such as Bombus balteatus , [] Bombus terricola , [] Bombus affinis , [] [] and Bombus occidentalis , and one, Bombus franklini , may be extinct. In the bumblebee researcher Dave Goulson founded a registered charity, the Bumblebee Conservation Trust , to prevent the extinction "of any of the UK's bumblebees.
The queens were checked for mites and American foulbrood disease. Agri-environment schemes spread across the neighbouring area of Romney Marsh have been set up to provide over hectares of additional flower-rich habitat for the bees. By the summer of , workers of the species were found near the release zone, proving that nests had been established.
The restored habitat has produced a revival in at least five "Schedule 41 priority" species: Williams, [] to assess the threat status of bumblebee species worldwide using Red List criteria. Bumblebee conservation is in its infancy in many parts of the world, but with the realization of the important part they play in pollination of crops, efforts are being made to manage farmland better.
Enhancing the wild bee population can be done by the planting of wildflower strips, and in New Zealand, bee nesting boxes have achieved some success, perhaps because there are few burrowing mammals to provide potential nesting sites in that country. According to 20th-century folklore , the laws of aerodynamics prove the bumblebee should be incapable of flight , as it does not have the capacity in terms of wing size or beats per second to achieve flight with the degree of wing loading necessary.
The origin of this claim has been difficult to pin down with any certainty. McMasters recounted an anecdote about an unnamed Swiss aerodynamicist at a dinner party who performed some rough calculations and concluded, presumably in jest, that according to the equations, bumblebees cannot fly. The following passage appears in the introduction to Le Vol des Insectes: First prompted by what is done in aviation, I applied the laws of air resistance to insects, and I arrived, with Mr.
Others say Swiss gas dynamicist Jacob Ackeret — did the calculations. The calculations that purported to show that bumblebees cannot fly are based upon a simplified linear treatment of oscillating aerofoils. The method assumes small amplitude oscillations without flow separation. This ignores the effect of dynamic stall an airflow separation inducing a large vortex above the wing , which briefly produces several times the lift of the aerofoil in regular flight. More sophisticated aerodynamic analysis shows the bumblebee can fly because its wings encounter dynamic stall in every oscillation cycle.
Additionally, John Maynard Smith , a noted biologist with a strong background in aeronautics, has pointed out that bumblebees would not be expected to sustain flight, as they would need to generate too much power given their tiny wing area.
However, in aerodynamics experiments with other insects, he found that viscosity at the scale of small insects meant even their small wings can move a very large volume of air relative to their size, and this reduces the power required to sustain flight by an order of magnitude.
The orchestral interlude Flight of the Bumblebee was composed c. It represents the turning of Prince Guidon into a bumblebee so he can fly away to visit his father, Tsar Saltan, in the opera The Tale of Tsar Saltan , [] although the music may reflect the flight of a bluebottle rather than a bumblebee. This early attempt at " surround sound " was unsuccessful, and the music was excluded from the film's release.
Or The Bumble Bee , under the pseudonym "T. Where Watts wrote "How skilfully she builds her cell! How neat she spreads the wax! Bumblebees appear as characters, often eponymously, in children's books. The surname Dumbledore in the Harry Potter series — is an old name for bumblebee. Rowling said the name "seemed to suit the headmaster, because one of his passions is music and I imagined him walking around humming to himself". Tolkien , in his poem Errantry , also used the name Dumbledor, but for a large bee-like creature. Al-Ghani ; Ben the Bumble Bee: How do bees make honey? Bumblebee is the name of a prominent character in the Transformers franchise.
His name denotes his black-on-yellow vehicle paint job, directly referencing the bee genus because of its black and yellow stripes. Bumblebee is also the name of an automotive racing stripe that wraps around the grill instead of down the centre of the vehicle; it can be found mainly on Chevrolet Camaros which happens to be the Transformers Autobot's most popular vehicle mode.

Even veteran beekeepers say it takes more effort to keep their bees alive these days. It is shelf stable with a long life. The results under such circumstances are that a very large force of bees that should be out working are employed fanning-, both inside and out, and often a considerable part of the colony will be hanging outside the hive in enforced idleness until it is ready to swarm.

Buff-tailed bumblebee Bombus terrestris. Healthy bees will invade a dying hive to steal its honey. When they do, they carry the mites with them back to their hives.
The University of Minnesota Bee Squad, a group that provides beekeeping education and mentoring in the Twin Cities, is seeing more healthy hives become rapidly infested with mites and the viruses they carry. Fall is an especially critical season, says Rebecca Masterman, the Bee Squad's associate program director. Masterman says she's also encouraging commercial beekeepers to check their bees more often for surprise mite infestations. A new online mite-monitoring project lets beekeepers anywhere in the country share data on infestations that will help researchers track the spread.
A mite control experiment this summer should provide more information about how to best treat mites in bee colonies. One threat to honeybees is the varroa mite, seen here invading the pupae of a developing bee. Untreated infestations will kill colonies.

Bees face other challenges beyond mites, including poor nutrition, disease and pesticides. Even veteran beekeepers say it takes more effort to keep their bees alive these days. It just sounds so awful. It's such a beautiful bee colony and to have to stick some kind of a treatment in there seems so unnatural," she says.
