The Bee Crisis

Post: # 172166Unread post Gary Oak »

I suspect that humans discovered honey long before 4,000 years ago. Those old hives look like they would work quite nicely and could be made fairly easily too. That stone carving of beekeeping from ancient Egypt is a sight.

Of Bees and Men

Whether wild or domesticated, beehives have been used by humans for thousands of years. Representations and archaeological traces since prehistory and technical treatises for historical periods have offered a glimpse into this long coexistence, as the first interdisciplinary conference devoted to bees takes place this week in Paris.


Bees have been much talked-about ever since they began showing signs of disappearing. These endangered insects would take with them much more than their precious honey, as a third of our food (vegetables, fruit, grains...) actually directly depends on their work of pollination. "Honey flies," as they were called during the Middle Ages, have in fact become indispensable to humans over the millennia...


Prehistory, the time of wild beehives

"One of the oldest representations of harvesting products from beehives was found on the walls of La cueva de la Araña, a Spanish rockshelter frequented by hunter-gatherers during the late prehistoric period," recounts Martine Regert, a prehistorian and chemist at the laboratoire Cultures et environnements. Préhistoire, Antiquité, Moyen Âge.[1] "It depicts humans using ropes to climb cliffs in order to gather honey from wild hives clinging to the rock face—a practice still in use today in certain parts of India and Nepal!" In fact, it is highly probable that humans have always sought the products of beehives. "Certain large monkeys such as chimpanzees are also partial to them, using sticks to extract honey from wild beehives located in tree hollows in the forest."

Gathering wild honey on cliffs in India. This technique was already practiced during the late prehistoric period.

Archeochemistry and chemical analyses conducted since the 1990s on thousands of sherds of ceramic vessels from archaeological sites in Northern and Southern Europe as well as the Near East confirm iconographic information: while honey is poorly preserved through the ages, traces of beeswax with a distinctive chemical fingerprint have been found in the porous clay matrix of over 6,000 pieces of pottery dating between the 7th and 2nd millennia BC. "It’s impossible to say whether these containers were filled with honey still containing beeswax traces, with pure beeswax, or whether they were simply waterproofed with beeswax," Regert nevertheless observes. "Regardless, they confirm the importance of beehive products during the Neolithic."


The first domesticated beehives 4000 years ago?

It is difficult, however, to say with certainty where and when humans began to practice beekeeping with domesticated hives, in addition to harvesting honey from wild hives... "In the Bronze Age—which is to say 2000 BC in Western Europe—an enormous amount of bronze objects were produced using something called the 'lost wax' method, which requires a large quantity of wax. This intensification probably required the use of domesticated hives," Regert suggests. In any event, the first representations of domesticated hives can be found in Egypt starting in 2400 BC, in the sun temple of Abu Gorab. The hives depicted are made of ceramic cylinders, a technique that was widely used in Egypt, and later along the Mediterranean rim in Greece beginning in the 5th century BC, and Spain during the 3rd century.

Bas-relief in Louxor (700 to 500 BCE). The oldest representations of domesticated beehives can be found in Egypt, beginning in 2400 BCE.

"The treatises written by ancient authors such as Pliny the Elder, Cato or Aristotle, who took great interest in bees, did not recommend terra cotta hives, because the temperature changes are would have been too important," points out Vincent Jolivet, an archaeologist at the laboratoire Archéologie et Philologie d’Orient et d’Occident.[2] Other materials were mentioned during Antiquity for constructing domesticated hives: woven reed or rush, wood... In the latter, a tree trunk is hollowed out for bees to glue their rows of cells; the log is then placed vertically, and capped with a lid.

"We know honey was traded everywhere around the Mediterranean, and that it had numerous uses, naturally for food, but also as a base ingredient for preparing medicine and cosmetics, or as an embalming product," Jolivet continues. He adds that while being transported, Alexander the Great's body was immersed in a coffin filled with honey from Sicily (Hybla honey), the most prized at the time!


The permanence of know-how

Despite the development of sugarcane farming and refining in Syria and Egypt, and its spread to Southern Europe, notably in the Iberian Peninsula and Sicily, honey continued to be the primary main source of sugar throughout the Middle Ages in Europe, where sugar cane long remained a luxury product. For all that, beekeeping techniques evolved little in comparison to the ancient period. "The body of ancient know-how was transmitted up to the Middle Ages, and was copied and diffused without major novelties," confirms Sylvain Burri, a medieval historian at the laboratoire Traces.[3] The primary techniques for producing hives have seemingly remained the same, with geographical variation and traditions: hives made of wickerwork or straw in Northern France, Germania and Flanders, trunk-hives or cylindrical cork hives in Mediterranean regions, and ceramic hives in North Africa.
Image
During the Middle Ages, log hives were widely used in Mediterranean regions (log hives of Gérard Delenne, a beekeeper located in Ardèche).

The technique for gathering honey also evolved very little; in the absence of movable rows (invented only in the 19th century), harvesting was necessarily destructive, and required sacrificing part of the swarm by cutting into the rows. "There are two types of harvests," Burri points out. "A total harvest, which means sacrificing the entire swarm in advance by drowning or asphyxiation. Or a partial harvest, where the bees are smoked out of the hive, a part of which is then cut and the other part will feed the bees during winter.'" The most destructive techniques are especially found in forested areas, where there were many wild swarms, making it easy to start a new one.

While there is no lack of texts and iconography to help retrace the history of beekeeping, archaeological traces of hives are exceedingly rare, as the straw, wicker and wood that were chiefly used are subject to rot and suffer from the weather; the same is true of bee remains. The discovery in 2007 of thirty hives made of unbaked clay dating back to 900 BC, at the archaeological site of Tel Rehov in Northern Israel, is still an exception. But researchers may not have had their last word.

I would think since the beginning of human beings that they have been eating honey, and had hives in one way, or another.
The stone age tribes still left today eat honey.
King Tut had honey in his tomb still edible even.
Mead, and other ancient drinks where made of honey.
The ancient Greeks, Minoans, Romans used honey, and the theory is Honey is Ambrosia the food of the gods.

Those tiny bee brains have must have to have conscious thought to navigate and find the flowers that they are told about.

Among the Many Talents of the Humble Honey Bee: Arithmetic

Honey bees are capable of understanding complex arithmetic, according to a new study published Wednesday.

Scientists discovered that bees can “learn to use blue and yellow as symbolic representations for addition or subtraction,” according to the report published in the peer-reviewed journal Science Advances.

While many animals demonstrate an understanding of basic numbers for tasks such as foraging, shoaling, and resource management, more complex math can be done only by a limited number of nonhuman vertebrates.

The findings are significant because honey bees and humans are separated by more than 400 million years of evolution, meaning that “advanced numerical cognition may be more accessible to nonhuman animals than previously suspected,” the study found.

Scientists created an experiment using mazes to test whether 14 bees could use yellow and blue to add and subtract. The study found that the bees got the right answer 63% to 72% of the time.

While the testing pool was small, the findings are significant given that brains of bees are 20,000 times smaller than those of humans. According to Science magazine, this could lead to new approaches to artificial intelligence and machine learning.

Now here's some good news ! :thumbsup:

Bee-wildering! Hives of Notre-Dame in miraculous survival

Paris (AFP) – Some 200,000 bees inhabiting hives in Notre-Dame cathedral survived the inferno that engulfed the heritage landmark in a miraculous escape, their beekeeper said Thursday.

“The bees are alive. Until this morning, I had had no news,” said beekeeper Nicolas Geant who looks after the hives which are kept on top of a sacristry that adjoins the cathedral.

“At first I thought that the three hives had burned but I had no information” after Monday’s fire, Geant told AFP.

“Then I saw from satellite images that this was not the case and then the cathedral spokesman told me that they were going in and out of the hives.”

Geant said he had been taken aback by calls of support from all corners of the world.

He said that this kind of bee does not abandon its hive, instead gorging on honey and not abandoning the queen bee.

Each hive at Notre-Dame on average produces some 25 kilogrammes of honey each year which is sold to Notre-Dame staff.

It has become increasingly customary in the French capital for bee hives to be introduced at seemingly unlikely locations, including also at the Paris Opera.

World's largest bee not seen for 38 years rediscovered on remote Indonesian island

A group of scientists and insect enthusiasts has rediscovered the world's largest bee while on an expedition on a remote Indonesian island.
Key points:

The bee was last recorded in 1981 and before that in 1859
It doesn't die after stinging, has a 6cm wingspan and giant pincers on its head
The team found the bee in a termite mound after searching for five days in a tropical forest

Dubbed "the flying bulldog", Wallace's giant bee (Megachile pluto) has a wingspan of a whopping six centimetres.

The giant bee has only been documented twice before: when it was first discovered by naturalist Alfred Russel Wallace in 1859, and then again in 1981.

With no sightings since, it was thought to be extinct.

While researching the bee's whereabouts, the University of Sydney's Simon Robson and his colleague Glen Chilton of Saint Mary's University in Canada heard of a US-based photographer and a young entomologist who were planning to go search for it.

The four insect detectives decided to pool their resources and expertise.

Early one morning in January they met in Jakarta, and scrambled for a connecting flight to the Moluccas Islands to try their luck.

The bee was named after the cofounder of natural selection, Alfred Russel Wallace, who first identified it to science.

"It was basically four people who had a long-term interest in this bee just got together and said, 'let's spend the money, we're going to go see if we can find it'," Dr Robson said.

"We met, we found it, we had a fantastic time, it was great! It was one of the best holidays I've ever had!"

The group searched through forest on an island in north-east Indonesia for five days in stifling tropical heat, checking termite nest after termite nest for signs of the bee.

The female bees burrow their way into termite nests to lay their eggs, leaving behind a tell-tale hole big enough to squeeze through.

"We were in the forest and it was late in the afternoon, and we were wandering off for a late lunch and one of us spotted a termite mound," Dr Robson said.

"One of us climbed up the tree and the hole was lined with resin and that was very encouraging, and we finally got the torch in there and we could see the bee in there looking out at us."

From there, they put a plastic tube over the hole in the termite nest and coaxed the bee out with a blade of grass to be photographed before releasing it.
'We were very keen to get stung by it'

The bee collects nectar to feed to its young, but doesn't produce honey like the European honeybee or some Australian natives.

And also unlike the European honeybee, it doesn't die after stinging, according to Dr Robson.

"This bee could probably sting you quite happily and then sting you again, it wouldn't kill it," he said.

"In fact, if we'd found more we were very keen to get stung by it to see how painful it was. But because we only found one we didn't want to annoy it and we didn't want to upset it."

Wallace's giant bee also has a large set of pincers called mandibles on its head, which Dr Robson said could probably "do a bit of damage".

Because the bee has only been seen a handful of times, scientists still don't know much about it.

For instance, it's possible that it may be a primary pollinator for a particular tree species in the islands where it is found, said entomologist Tim Heard, who was not involved in the discovery.

"That's quite possible, but we don't know that. We don't really know what it pollinates or if the the plant that it pollinates has an obligate relationship to that bee," said Dr Heard, an Australian bee expert at the University of Sydney.

Regardless of its ecological niche, Dr Heard said it needed protection from threats such as deforestation for palm oil, which is rife throughout Indonesia.

"I think we have a responsiblity to preserve all life on this planet," he said.

"It being the biggest bee in the world, it's rare, and it was discovered by Wallace, who was a legend in his field — he discovered evolution via natural selection along with Darwin.

"The fact that it's such a spectacular species and is such an amazing product of evolution, we have an obligation to preserve it."

Dr Robson said he and his colleagues hoped the presence of the bee in the Moluccas Islands could become a flagship for environmental conservation and ecotourism in the region.

"Deforestation is the major threat to most things and that can sometimes come into [regions] very quickly," he said.

"We may be able to get this bee in the eyes of the public as something that's worth coming to see."

I see them as big as 2 1/2 inches here, not sure how big they are there, but in that pic they look comparable. Maybe we had some imported from Asia, wouldn't surprise me.

I must have seen stingless bees in Borneo however didn’t recognize them for what they are. They certainly are different looking. Perhaps the answer to how they came up with the spiral honeycombs is the bible scripture a friend showed me once “God gives every creature a certain knowledge” though I may not have remembered that scripture word for word.https://www.livescience.com/61492-spira ... xRD2PmBGBs

Can this be true ? This Beeflow bee food can increase worker bee flights by seven times !? If this is this is true then perhaps this beeflow bee food will help against colony collapse syndrome. https://www.bloomberg.com/features/2019 ... essweek-v2

Making Better Worker Bees

Beeflow says its proprietary nutrient liquid can supercharge pollination.

The beekeepers who help pollinate some 70% of the world’s crops charge $435 million for their services each year in the U.S. alone. One way farmers can increase their return on investment is to hire better bees.

Argentine startup Beeflow says it has more than doubled its tiny workers’ pollen-carrying capacity by feeding them custom compounds. The nutrients enhance the bees’ immune systems to handle colder conditions and also increase their attraction to the particular flower the farmer wants them to pollinate—blueberries, raspberries, or the all-important almonds. The 2-year-old company tested its insect fuel this season in the fields of a major California almond farmer and on raspberry crops for Driscoll’s, America’s largest berry grower. On deck: cherries and avocados.

Beeflow says its proprietary nutrient liquid can enable bees to carry out as many as seven times more flights, with each bee carrying more than double its usual pollen load.

Workers on the ground pour about a gallon of the liquid formula into each hive, which holds as many as 50,000 bees, close to double the beekeeping standard.

Beeflow estimates that a 9-acre pilot project at a blueberry farm in Aurora, Ore., this winter increased yields by 25% and berry size by 22%. Beeflow recently closed a $3 million round of seed funding to expand.

This can't be good for bees. Flying all those extra trips will reduce a bees lifespan which is short enough.

435 million dollars ! Beekeeping isn’t so hard. Surely they must do their own bees. I read or heard before that some people are using methods to use native bees as they tend to work longer hours.
