November 12, 2013 Why Bees Must Keep Buzzing
Are you aware that honeybees in America generate in excess of $44 billion in commerce, annually? I’ve been intrigued with bees all my life. They continue to show my colleagues important new information. Bees are most certainly modern-day canaries in coal mines, worldwide.
Recently, Italian researchers from the University of Trento found that just like humans shake with their right hands, honeybees also greet each other by predominantly using their right antennas. Apparently, the right antenna picks up on certain ‘social cues’ including recognition of their hive mates.
Bee brains might be small, but they are packed with about 960,000 functional neurons (compared to 86 billion for humans). Bee neurons enable them to clearly recognize a human face as well as exactly communicate by dancing where food (nectar and pollen), water and tree resin (used along with bee enzymes for making potent anti-microbial propolis or glue) are located as far as eight miles away.
A team of scientists lead by Cardiff University has just revealed some fascinating secrets of bees’ honeycomb.
Honeycomb is a precise hexagon, six-sided, wafer-thin wax that honeybees make from their abdomen, which provides phenomenal strength for storage of honey. Two pounds of beeswax supports 48 pounds of honey! By the way, over a half a century ago the aeronautics industry recognized the strength of honeycomb and adapted nature’s design to enhance the bending and stiffness of aircraft wings, as the wings must support loads of fuel in the aircraft.
It turns out that honeycomb starts out as a circle and gradually forms into a hexagon. The subtle flow of wax is turned semi-molten by the heat of 113 degrees from a special class of worker bees. The wax becomes elastic, stretching like toffee forming a tiny point that becomes a perfect angle within the hexagon. Some incredible physics and math occur in order to form honeycomb.
Frighteningly, something is going very wrong around the globe in our environment: 20,000 species of bees are showing scientists they are in trouble. Just 20 years ago across America each of our 2.4 million commercial beehives produced about 100 pounds of honey. Today they each produce almost half that amount. In part, their natural diverse forage has been drastically reduced or more likely destroyed altogether. Bees, like to dine, not dissimilarly to people, at smorgasbords. Monoculture food crops cannot supply bees with enough nutrition.
This much we do know. Over the past 110 million years, plants and bees have co-evolved; they depend on one another, when bees die en masse and rapidly all-hell-breaks-loose: Global food security is jeopardized. Researchers affiliated with the Rocky Mountain Biological Laboratory at Crested Butte, Colorado recently discovered by removing just one species of bumblebee that one third fewer seeds were produced in Rocky Mountain subalpine wildflowers.
There’s one class of pesticides known as neonicotinoids with about 1,000 kinds available, globally. When honeybees are exposed to as little as four billionths of a gram of neonicotinoid’s they suffer irreparable poisoning.
Last week, the European Health & Safety Authority banned a fourth neonicotinoid (Fipronil). This week, 36,000 solitary bees were found dead in all 12 nesting boxes on a farm in Niestetal, Germany; poisoned pollen has been implicated. A couple weeks ago, 37 million honeybees died in 600 hives on an organic honey farm in Elmwood, Canada just after corn seed coated in neonicotinoid’s was planted. A few weeks before that, 55 American linden or ‘bee trees’ were sprayed with a neonicotinoid (Safari) and 50,000 bumblebees perished in Wilsonville, Oregon.
In order to keep the bees buzzing it is clearly time to stop pesticides that are known to kill them. If the bees die, we die. We need The Save America’s Pollinator Act of 2013. I signed the petition and encourage you, to do so.
