While such disappearances have occurred throughout the history of apiculture and were known by various names disappearing disease spring dwindle May disease autumn collapse and fall dwindle disease1 the syndrome was renamed colony collapse disorder in late 20062 in conjunction with a drastic rise in the number of disappearances of western honey bee Apis mellifera colonies in North America.3 European beekeepers observed similar phenomena in Belgium France the Netherlands Greece Italy Portugal and Spain4 Switzerland and Germany albeit to a lesser degree5 and the Northern Ireland Assembly received reports of a decline greater than 50.Colony collapse disorder causes significant economic losses because many agricultural crops worldwide are pollinated by western honey bees. According to the Agriculture and Consumer Protection Department of the Food and Agricult
Bumble bee necklace silver Honey Bees vs Native BeesBy Robert Pavlis on April 23 2017This is not a comparison of honey bees and wild native bees. Instead I will discuss the missuse of the word bee and how this is leading the general public to reach all kinds of incorrect conclusions.Headlines about bees are common but many are incorrect or at least misleading. What do these headlines really mean Which bees are they talking aboutThe Bees are DyingWe Will All Starve If We Dont Save the BeesIs this a honey bee or native beeThe Honey BeeThe honey bee is a nonnative import into North America and most other countries. It is native to Africa or Asia but has been domesticated for hundreds of years. From Wikipedia a honey bee is any bee member of the genus Apis primarily distinguished by the production and storage of honey and the construction of perennial colonial nests from wax.Honey bees are farmed and kept in bee hives tho

See the differenceIf one taxonomic error is repeated in the media more than any other it is the inability to distinguish between honey bees Apis mellifera and bumble bees about 250 species in the genusBombus. Such errors are frustratingly common for insects that should be easy to recognize.Here for example is a recentstory that mistakes a bumble bee for a honey bee and here is one that does the opposite. Even the New York Times has stepped in this equivocation.Both honey bees and bumble bees are among the most abundant flowervisiting insects in the northern hemisphere. How do we tell the difference Ive made a chartBumble bees vary greatly in size but they tend to be furry and relatively pudgy. These two bees are sisters from the same nest.Honey bees are slender and more wasplike in appearance bearing a stronger more obvious pattern of stripes.Clear
Mykinkydope.com spp. look like bumble bees. The largest in California are the Central Valley carpenter bees X. tabaniformis orpifex more than an inch long. The females are solid black but the males are goldenblond. The males are sometimes nicknamed teddy bears because of their soft burly and fuzzy appearance. See the three California species at httpentomology.ucdavis.edunewsvalleycarpenterbees.html.Carpenter bees nest in soft wood and pithy stems of plants. Nests usually consist of tunnels half of an inch in diameter and 6to10 inches deep and may include several brood chambers. Carpenter bees may buzz like saws when constructing nests hence their name but they do not eat the wood. Instead they forage on flowering plants feeding on nectar with the females collecting pollen for their offspring. When they have a sufficient plug of pollen in a chamber females lay an egg on it and then seal the chamber with woodchips. Another plug of pollen is then added for numerous chambers per tunnel. Development from egg to larva to adult may take about three months. Carpenter bees overwinter as ad

Thailand live cam chat History of Africanized Honey BeesThe Africanized honeybee dubed by the media as killer bees is a cross between the European honeybee and bees from Africa. There are no records of ancient beekeeping in Africa the historical practice of beekeeping in Africa is relatively new compared to Europe. In Africa humans as well as animals the Ratel or honey badger among other predators would destroy the beehive to get the honey. Other extreme conditions of Africa likely created an enviroment were the more feral or aggressive beehive survived the fiercer the honeybees in their ability to protect their home and to relocate to liveable or safe areas likely would better survive. This could be what caused the African honeybee to developed differently over time than the honeybee from Europe.In the 1950s European honeybees were the preferred bee for South American. Though unlike African honeybe
Free limited video sex chat Bumble bee paradox solved1201AM GMT 31 Jan 2007The enduring puzzle of why bees and other insects are so good at flying has been solved paving the way for a new generation of robot insects measuring just a few inches to be built. Flying insects have plagued the worlds of science and engineering ever since the first calculation of bumblebee aeronautics was attempted at Gottingen University in the 1930s. Conventional aerodynamics seemed to suggest that the insect should not generate enough lift to fly. The bees stayed resolutely airborne and the sums caused consternation. The underlying problem turned out to be treating a wing as if it was fixed like in an aeroplane and thanks to studies over the past few years including the construction of robotic bees this bumblebee paradox has been solved extra lift comes when flexible insect wings slice through the air at a high angle of attack creating a large swirling vortex at their leading edge. In this way insect wings produce the vortices spinning masses of air which generate lift and help them move. Today Prof Ismet Gursul of the University of Bath will describe another step on the way for engineers to make air vehicles smaller than a human hand that can be used for detecting chemicals leaks and reconnaissance. His research was carried out as part of a programme to develop tiny aircraft with cameras and sensors which could be used in traffic monitoring border surveillance fire and rescue operations. As aircr
