California Dearth Conditions

via HoneyLover Susan Rudnicki

Beeks—As you are probably reading everywhere, California is in the middle of a extended drought and this significantly affects the available food—pollen and nectar—for our bees. People can get a false sense of security about this problem since all around are extensive irrigated landscapes— golf courses, industrial parks, shopping malls with fountains and lush landscaping, apartment and condo blocks, and private homes.

However, all this is carried out by the importation of precious water from underground aquifers and water resources channeled from the middle and northern part of the state. Irrigation with re-claimed sewer water—-designated by the required violet colored pipes and valve box covers—is still a anomaly, unfortunately. Our streets are still running with rivers of wasted water, too.

For a simple tabulation of the history of the rainfall pattern, go here: http://www.laalmanac.com/weather/we13.htm

You will see, since 2000, we have been much under normal 8 years and only in excess 5 years—and not that much in excess, when the average for 135 years is only 15 inches. The population of California is projected to be 60 million by 2050, from the 34 million counted in 2007. The water is not going to be there to sustain this many people in the lifestyle currently practiced.

Many beeks are noticing their bees have small stores of honey, or sometimes, nothing. I am seeing cutouts with lots of brood, but almost NO honey/nectar stores. As beekeepers, this is important for us to monitor when doing inspections of our hives and when trying to support small nucs and cutouts after the trauma of the operations when we move them. We may need to feed our bees to help them manage the loss of available food supply—called a “dearth” –if we wish for them to be around for us come Spring. The best food for bees is their natural food—honey. This can be provided by frames of honey taken from strong hives. “junk comb” from cutouts, and honey purchased for the specific feeding purpose. A bee has a natural acidic pH in her gut that is supported by many strains of bacteria, fungi, and other microbes adapted to that pH environment. When we feed sugar or high fructose corn syrup, the more alkaline nature of these sugars alters the gut pH. Some scientists believe this is not beneficial to the gut microbes that serve the bee’s immune system. However, if the situation is one of the choice between starvation or feeding sugar, we may need to feed the sugar syrup to get by until there is a natural nectar flow.

4 States Just Got a Little Bit Safer for Bees

by Alicia Graef via care2.com

Environmentalists have been warning about the problems associated with a class of pesticides known as neonicotinoids (neonics) on pollinators and other wildlife, but now there’s some good news that comes with a decision from the U.S. Fish and Wildlife Service (FWS) to phase out these toxic chemicals on wildlife refuges in the Northwest and Hawaii.

Neonics can be used in sprays, but are often applied as a coating on agricultural seeds and when it is, it spreads throughout the plant as it grows making the whole thing poisonous to a variety of insects. Studies have shown that they can be lethal to honey bees, bumble bees and other species at high doses, but even a little bit can cause problems by making them more vulnerable to other stressors. They’ve also been linked to Colony Collapse Disorder and have recently been found to be harmful to aquatic invertebrates and birds.

That’s not just bad news for pollinators, it’s bad news for us and the wild animals who depend on them to help pollinate crops and other wild plants we all depend on for food.

Earlier this year environmental organizations petitioned the agency to ban both genetically engineered crops and neonics throughout the National Wildlife Refuge System over concerns about the dangers they pose to wildlife and protected species and because their use is inappropriate on land that’s supposed to be designated to protect wildlife and conserve habitats.

In a memorandum published by the Center for Food Safety earlier this month, the FWS acknowledged that neonics could have adverse effects on a “broad-spectrum of non-target species” and agreed that their use does not meet the intent of policies that are supposed to cause the least harm to wildlife and their habitats. The agency also noted that they’re not only potentially being used on agricultural crops that are grown on wildlife refuges, but that they may be getting introduced through plants used in restoration projects.

Kim Trust, the deputy regional director of the FWS, told the AP that the agency made the decision because it is concerned about the global decline in all pollinators.

As of now, refuge managers will be required to take other steps to avoid their use on close to 9,000 acres of land in Hawaii, Idaho, Oregon and Washington and should have neonics completely phased out by January 2016.

“We commend the Service for taking its first step to ban neonicotinoids in the Pacific region, and now we call on the agency to permanently institute this policy on wildlife refuges nationwide,” said Paige Tomaselli, senior attorney with Center for Food Safety. “Federal wildlife refuges were established to protect natural diversity. Allowing chemical companies to profit by poisoning these important ecosystems violates their fundamental purpose and mission.”

Beehive Air-Conditioning via @nytimes

Q. Why are honeybees drinking water from my birdbath?

A. The birdbath may be closer to the hive than a natural source of water, said Cole Gilbert, a Cornell entomologist. Or the bees may have discovered it while foraging for nectar and pollen, then returned when conditions in the colony changed.

Bees collect water from many nonpure sources — even urine, by one report, Dr. Gilbert said — but prefer pure water, like that in a birdbath, when specifically foraging for it.

The most important factor in a hive’s water requirements is temperature control in the area where larvae are raised.

Water is collected by the same means as nectar, by sucking through the proboscis, Dr. Gilbert said. It is stored in the honey stomach, a pouch where nectar is also stored. “When foragers return to the hive, the water is regurgitated and passed by trophallaxis, a fancy word for mouth to mouth, from the forager bee to a younger hive bee,” he said.

While the hive bee smears droplets on the comb, other bees hang out near the hive entrance, fanning their wings to increase airflow through the hive. The vaporizing droplets remove heat.

When extra water is needed, a hive bee signals to a forager bee by refusing to take her nectar for some time. When it is eventually accepted, the forager bee looks for water on her next foray.

List of Foods We Will Lose if We Don’t Save the Bees

By: Christina Sarich, Natural Society.

800px-Bee-apis-300x200

Many pesticides have been found to cause grave danger to our bees, and with the recent colony collapses in Oregonit’s time to take a hard look at what we would be missing without bee pollination.

In just the last ten years, over 40% of the bee colonies in the US have suffered Colony Collapse Disorder (CCD). Bees either become so disoriented they can’t find their way back to their hives and die away from home, or fly back poison-drunk and die at the foot of their queen. There are many arguments as to what is causing CCD, but the most logical and likely culprit is the increased usage of pesticides by the likes of Monsanto and others.

A study by the European Food Safety Authority (EFSA) has labeled one pesticide, called clothianidin, as completely unacceptable for use, and banned it from use entirely. Meanwhile, the U.S. uses the same pesticide on more than a third of its crops – nearly 143 million acres. Two more pesticides linked to bee death are imidacloprid, and thiamethoxam. These are also used extensively in the US, while elsewhere, they have been taken out of circulation.

Recently, the FDA also seized Terrence Ingram’s bees, a naturalist who had been studying bees for over 30 years, and had a  colony that was resistant to Monsanto’s Round Up. Ingram’s prized hives, along with their queens, were destroyed by the FDA, and Ingram was given no warning that his bees would be demolished.

Oregon bans some insecticides following bee deaths

By John Upton via grist.org

Bees and other insects can breathe a little easier in Oregon — for now. The state has responded to the recent bumbleocalypse in a Target parking lot by temporarily banning use of the type of pesticide responsible for the high-profile pollinator die-off.

For the next six months, it will be illegal to spray Safari or other pesticides [PDF] containing dinotefuran neonicotinoids in the state.

Oregon’s ban comes after more than 50,000 bumblebees and other pollinators were killed when Safari was sprayed over blooming linden trees to control aphids in a Wilsonville, Ore., parking lot. A similar incident in Hillsboro, Ore., was also cited by the state’s agriculture department as a reason for the ban.

Oregon Department of Agriculture Director Katy Coba said in a statement [PDF] that she has directed her agency to impose the ban to help prevent further such “bee deaths connected to pesticide products with this active ingredient until such time as our investigation is completed. Conclusions from the investigation will help us and our partners evaluate whether additional steps need to be considered.”

Somewhat confusingly, retailers will still be allowed to sell the products. It will just be illegal for landscapers and gardeners to actually use them. From The Oregonian:

“We’re not trying to get it off the shelves, or trying to tell people to dispose of it, we’re just telling people not to use it,” said Bruce Pokarney, a spokesperson for the department of agriculture.

While Pokarney acknowledged it would be difficult to cite individual homeowners, he said licensed pesticide applicators would be violating Oregon regulations if they use dinotefuran-based insecticides on plants in the next 180 days.

The temporary ban only affects pesticide use that might harm pollinators, like bumblebees. Safari is one of the insecticides restricted by the Agriculture Department. Most of the restricted insecticides are used primarily for ornamental, not agricultural, pest control.

Dinotefuran use in flea collars, and ant and roach control will still be allowed.

The Xerces Society, a nonprofit insect conservation group that’s helping to investigate the pollinator die-offs, thinks the temporary ban is a good idea. But Executive Director Scott Black said it would be an even better idea if sales of the pesticides were suspended, lest consumers unwittingly use them in violation of the law. “At a minimum, all products on the shelf should have clear signage about the restriction on their use,” he told Grist.

Guess who thinks the ban is not such a good idea?

“We do not believe the scope of these measures is necessary with the information available,” Safari manufacturer Valent said in a statement, “and we will work to get the restrictions lifted as soon as possible.”

READ: “Local organisation introduces urban beekeeping”

By Adel Heine via dailynewsegypt.com

The current trend of eating a healthy diet has inspired many to switch to organic produce. And while supermarkets now offer organic options, some are taking it a step further and are growing their own vegetables in their gardens, rooftops and balconies. Nawaya, a not-for-profit initiative that promotes true sustainability, organised a workshop recently that introduced yet another possibility to produce your own food: honey.

Urban beekeeping is becoming more popular around the world and according to Sara El Sayed, one of the founders of Nawaya; the workshop fits perfectly with the organisation’s goal of bringing people closer to producing their own food.

“Bees are vitally important to farming, they are needed to pollinate crops,” El Sayed said. “Keeping your own bees will allow you to have access to your own honey, of course,” she added.

Producing your own raw honey is also healthier, according to El Sayed. “Bees collect nectar in an area with a radius of three kilometres so the honey they produce comes from your direct surroundings. The immune system boost that honey provides is greatest when it is directly related to where you live,” she explained.

The workshop provided an introduction to the practicalities of keeping bees and how the bees live. “We do not have any in-house experts on beekeeping so we brought in two, each with a unique practice in beekeeping,” El Sayed said.

The first expert, Sheikh Said, works at St. Catherine’s in Sinai and his bees feed on plants that are endemic to the area. “The plants that grow around St. Catherine’s are used by the local population for their medicinal qualities and the honey that bees produce have these qualities too,” El Sayed said. “Sheikh Said brought one of his colonies with him and showed us how to maintain the lifecycle of the bees.”

Islam Siam, the second expert, works with Sekem and his bees produce a traditional kind of honey from the area around Assiut in Upper Egypt. “His colonies consist of bees that are native to Egypt, as opposed to many other beekeepers that keep an Italian variety of bees,” El Sayed said. “Also the bees are not kept in boxes but in traditional clay columns.”

Most honey is obtained by centrifuging the combs, but the honey Siam produces is made a little differently. “He uses the traditional way of crushing part of the wax in the honey, which means some of the pollen and the antibiotic that the bees produce to keep their own kind healthy is part of the honey. This makes it very healthy and a great boost for the immune system,” El Sayed explained.

Raw honey is believed to help with a variety of health issues besides strengthening the immune system. It is said to be good for many skin diseases as well.

“This workshop was an introduction to what it means to keep bees in an urban environment, how to do it and how to taste the different honeys. We plan to follow it up with how to build and maintain your own colony,” El Sayed said.

When asked if neighbours would not object to people hosting a swarm of bees on the balconies El Sayed said: “Bees are everywhere, we just do not notice them. Having a colony on your balcony might not be ideal but it would be very possible on a rooftop, especially one that is not used very often. Bees will not sting you unless you annoy them.”

To produce your own honey you would need to keep a colony for around one year but it shouldn’t take up too much of your time. “You need to monitor for disease, make sure the temperature for the colony is OK and that there is enough honey to get the bees through the winter months,” El Sayed explained. “It is not hard to do, it gives you a product that is very healthy and you help the environment because you will help to ensure that pollination takes place in your area.”

There are no concrete plans yet to organise the second beekeeping workshop but of those who attended the first one, more than half expressed an interest in having their own colonies. According to El Sayed, beekeeping also serves a greater purpose.

“Besides all the personal benefits we also felt it was necessary to raise the issue of the danger beekeeping is in. Not many people are aware that bees are under threat in many parts of the world due to the use of pesticides and without bees there will be no pollination which means no produce,” she said.

READ: How neglecting bees could endanger humans

Bees pollinate much of our food supply, but a pesticide threatens their survival
BY RICHARD SCHIFFMAN

If you are an almond farmer in the Central Valley of California, where 80 percent of the world’s production is grown, you had a problem earlier this spring. Chances are there weren’t enough bees to pollinate your trees. That’s because untold thousands of colonies — almost half of the 1.6 million commercial hives that almond growers depend on — failed to survive the winter, making this the worst season for beekeepers in anyone’s memory. And that is saying a lot, because bees have been faring increasingly poorly for years now.

Much of this recent spike in bee mortality is attributed to Colony Collapse Disorder, a mysterious condition where all the worker bees in a colony simply fly off as a group and never make it back to the hive. Scientists have been studying this odd phenomenon for years and they still aren’t sure why it is happening.

But a slew of recent studies have pointed an accusing finger at a class of pesticides, the ubiquitous neonicotonoids (neonics for short), which include imidacloprid and clothianidin, manufactured by Germany’s agro-giant Bayer, and thiamethoxam, made by Syngenta. The neonics, the world’s leading insecticides, are applied on a whopping 75 percent of the farmlands in America, according to Charles Benbrook, research professor at Washington State University’s Center for Sustaining Agriculture and Natural Resources. Neonics are a so-called systemic pesticide. That means that they are taken up by the plant’s vascular system and get impregnated into all parts of the plant that an insect encounters, including the leaves, seeds, nectar and pollen. Corn and soybean seeds are typically coated with the pesticide before planting. Fruit trees and many vegetables are sprayed.

Few researchers believe that the neonics alone are to blame for the bees’ troubles, which appear to result from a perfect storm of contributing environmental factors. Pollinators have been called the canaries in the coal mine for ecosystem health. The declining numbers of both wild species and domesticated bee colonies worldwide is regarded as a troubling barometer of the state of the environment, reflecting habitat loss, the spread of agricultural monocultures, infestation by viral pathogens and bee parasites like the Varroa mite, climate change and even electromagnetic radiation, which seems to interfere with bees’ homing ability.

But the neonics, which contains a chemical related to nicotine that attacks an insect’s nervous system, have been demonstrated to kill bees — and especially the queens — when applied in high enough doses. And a growing body of research suggests that at sub-lethal concentrations, these agro-chemicals mess with their navigation, foraging and communication abilities, throw off their reproductive patterns, and weaken bee immune systems, making them susceptible to sudden colony collapse.

One study published by scientists at Purdue University in 2012 showed high levels of clothianidin and thiamethoxam in bees found dead near agricultural fields. Other bees at the hives were observed exhibiting uncoordinated movement, tremors and convulsions, all signs of insecticide poisoning.

In yet another study conducted by scientists at the Harvard School of Public Health, which I reported on in Reuters last April, researchers actually re-created colony collapse disorder in several honeybee hives simply by administering small doses of a popular neonic, imidacloprid.

These and other recent studies led the European Union to call on Monday for a provisional ban on neonics for two years to see what impact this has on Europe’s endangered bees. The use of the pesticides had already been temporarily suspended in Germany, France and Italy.

The vote in Brussels was split (15 of the 27 EU countries voted for the ban). The British Newspaper the Observer said that there was “a fierce behind the scenes” campaign to prevent the ban. The paper reported that agricultural multinational Syngenta, facing what it called “serious damage to the integrity of our product and reputation,” threatened to sue individual European Union officials involved in publishing the damning report about the dangers of neonics. The U.K. voted against the ban, alleging that the science is inconclusive and that barring the pesticides would be hugely expensive and potentially cripple food production.

But the ban had lots of public support, including a petition signed by over 2.5 million Europeans. And it was universally applauded by environmentalists, who have been fighting for it for years. Andrew Pendleton of the U.K division of Friends of the Earth said: “This decision is a significant victory for common sense and our beleaguered bee populations. Restricting the use of these pesticides could be an historic milestone on the road to recovery for these crucial pollinators.”

Pressure has been building in the U.S. to restrict the neonics. A coalition of beekeepers and environmental groups filed suit in March against the U.S. Environmental Protection Agency for its failure to ban the pesticides, saying that the agency didn’t consider the impact of the pesticides on vital pollinators. The American Bird Conservancy published in March a review of 200 studies on neonics, including industry research obtained through the U.S. Freedom of Information Act, which concluded that the neonics are lethal to birds and other wildlife and to the aquatic systems on which they depend.

These threats to wildlife are significant, but the world’s attention is rightly focused on bees, which are responsible for pollinating nearly a third of our food supply. These industrious insects are in serious trouble. And if their decline continues unchecked, we humans may soon be in trouble too.
