"If the bee disappeared off the surface of the globe then man would only have four years of life left. No more bees, no more pollination, no more plants, no more animals, no more man." Albert Einstein
The number of managed colonies dropped from 5.9 million in 1947 to 2.4 million in 2005. While scientists have identified potentials causes of this year’s colony decline, there is no evidence that a single major problem has led to this long-term decrease. However, my experimental observation has shown that bees’ immune systems have been weakened significantly due to a number of factors. Once their immune systems have been compromised, colonies are less capable of overcoming such problems as mites, extremely cold weather, solar activity or diseases and viruses (as is probably the case with the Colony Collapse Disorder). The overall set of issues that has had a negative impact of bee immune systems can be divided into two groups: those that directly depend on bee management techniques, and those that do not. As such, the purpose of this article is to consider how beekeepers can help strengthen the immune systems of colonies in order to prepare them to combat a plethora of negative factors that the colonies will face continuously.

Abstract
Since seed coating with neonicotinoid insecticides was introduced in the late 1990s, European beekeepers have reported severe colony losses in the period of corn sowing (spring). As a consequence, seed-coating neonicotinoid insecticides that are used worldwide on corn crops have been blamed for honeybee decline. In view of the currently increasing crop production, and also of corn as a renewable energy source, the correct use of these insecticides within sustainable agriculture is a cause of concern. In this paper, a probable-but so far underestimated-route of environmental exposure of honeybees to and intoxication with neonicotinoid insecticides, namely, the atmospheric emission of particulate matter containing the insecticide by drilling machines, has been quantitatively studied. Using optimized analytical procedures, quantitative measurements of both the emitted particulate and the consequent direct contamination of single bees approaching the drilling machine during the foraging activity have been determined. Experimental results show that the environmental release of particles containing neonicotinoids can produce high exposure levels for bees, with lethal effects compatible with colony losses phenomena observed by beekeepers.
In 2006, when beekeepers began to report that their hives were suffering from a mysterious affliction, a wide variety of theories were offered to explain what was going on. The bees were suffering from a virus, or a fungus, or a mite, or from stress, or, according to one much publicized hypothesis, they were being addled by cell-phone signals. (Supposedly the transmissions interfered with the bees’ navigational abilities.)
The Pennsylvania beekeeper Dave Hackenberg was one of the first to draw attention to the problem of Colony Collapse Disorder, or C.C.D., and, as a result, he became a celebrity, at least in apian circles. I interviewed Hackenberg in the spring of 2007, and he told me he didn’t believe that the culprit was a virus or a fungus or stress. Instead, he blamed a new class of pesticides called neonicotinoids. Now it looks like Hackenberg was onto something.
Over the last few weeks, several new studies have come out linking neonicotinoids to bee decline. As it happens, the studies are appearing just as “Silent Spring,” Rachel Carson’s seminal study of the effect of pesticides on wildlife, is about to turn fifty: the work was first published as a three-part series in The New Yorker, in June, 1962. It’s hard to avoid the sense that we have all been here before, and that lessons were incompletely learned the first time around.
In the first of the new studies, published online in the journal Science, British scientists raised bumblebees on a diet of pollen, some of which had been treated with a widely used neonicotinoid called imidacloprid. Those colonies that had received the treated pollen suffered significantly reduced growth rates and produced dramatically fewer new queens. In the second, also published in Science, French researchers equipped honeybees with tiny radio-frequency tags. They fed some of the bees sucrose treated with thiamethoxan, another commonly used neonicotinoid. Then they let the bees loose to go foraging. The bees that had been exposed to thiamethoxan were much less likely to return to their hives. “We were quite surprised by the magnitude of the effect,” said one of the study’s authors, Mickaël Henry, of the French National Institute for Agricultural Research in Avignon.
In a third study, to be published soon in the Bulletin of Insectology, seemingly healthy honey colonies were fed high-fructose corn syrup that had been treated with imidacloprid. Within six months, fifteen out of the sixteen hives that had been given the treated syrup were dead. In commercial beekeeping operations, bees are routinely fed corn syrup, and corn is routinely treated with neonicotinoids.
“I believe one reason that commercial beekeepers are experiencing the most severe Colony Collapse Disorder is because of the link between high-fructose corn syrup and neonicotinoids,” said the lead author of the study, Chensheng Lu, a professor at Harvard. (Bayer CropScience, one of the world’s largest producers of neonicotinoids, has disputed Lu’s paper, as well as the other two.)
After the results of Lu’s study were reported, I reached Hackenberg on his cell phone. He was in Pennsylvania, where his bees were pollinating apple trees, and he was preparing to take them up to Maine to pollinate blueberries. He told me that because of the freakishly warm weather in the Northeast last month everything was flowering two to three weeks earlier than normal.
“This more or less proves what we thought all along,” Hackenberg said of the three recent studies. He pointed me to a lawsuit that several beekeeping organizations filed in March against the Environmental Protection Agency. It charges that the E.P.A. violated its own rules by allowing clothianidin—yet another neonicotinoid—to be widely used despite the fact that the field studies the agency had ordered on the effects of the pesticide had never been performed. In a leaked memo from 2010, two E.P.A. staff members raised concerns about allowing mustard and cotton seed to be treated with clothianidin, noting that the field tests that had been completed had been deemed to be inadequate.
“I think we’ve got a toxic mess,” Hackenberg told me. “I know we do.”
Neonicotinoids, which were introduced in the nineteen-nineties, are neurotoxins that, as the name suggests, chemically resemble nicotine. They’re what are known as systemic pesticides: seeds are treated with the chemicals, which then are taken up by the vascular systems of the growing plants. According to the Pesticide Action Network, at least a hundred and forty million acres were planted with neonicotinoid-treated seeds in 2010. This is an area larger than California and Florida combined.
In “Silent Spring,” Rachel Carson wrote of systemic pesticides with particularly vivid horror:
The world of systemic insecticides is a weird world, surpassing the imaginings of the brothers Grimm. It is a world where the enchanted forest of the fairy tales has become a poisonous forest. It is a world where a flea bites a dog and dies…where a bee may carry poisonous nectar back to its hive and presently produce poisonous honey.
“The hives were dead silent,” Lu, the author or the corn-syrup study, said of the boxes treated with imidacloprid. “I kind of ask myself: Is this the repeat of Silent Spring? What else do we need to prove that it’s the pesticides causing Colony Collapse Disorder?”

Monsanto, the massive biotechnology company being blamed for contributing to the dwindling bee population, has bought up one of the leading bee collapse research organizations. Recently banned from Poland with one of the primary reasons being that the company’s genetically modified corn may be devastating the dying bee population, it is evident that Monsanto is under serious fire for their role in the downfall of the vital insects. It is therefore quite apparent why Monsanto bought one of the largest bee research firms on the planet.
It can be found in public company reports hosted on mainstream media that Monsanto scooped up the Beeologics firm back in September 2011. During this time the correlation between Monsanto’s GM crops and the bee decline was not explored in the mainstream, and in fact it was hardly touched upon until Polish officials addressed the serious concern amid the monumental ban. Owning a major organization that focuses heavily on the bee collapse and is recognized by the USDA for their mission statement of “restoring bee health and protecting the future of insect pollination” could be very advantageous for Monsanto.
In fact, Beelogics’ company information states that the primary goal of the firm is to study the very collapse disorder that is thought to be a result — at least in part — of Monsanto’s own creations. Their website states:
While its primary goal is to control the Colony Collapse Disorder (CCD) and Israeli Acute Paralysis Virus (IAPV) infection crises, Beeologics’ mission is to become the guardian of bee health worldwide.
What’s more, Beelogics is recognized by the USDA, the USDA-ARS, the media, and ‘leading entomologists’ worldwide. The USDA, of course, has a great relationship with Monsanto. The government agency has gone to great lengths to ensure that Monsanto’s financial gains continue to soar, going as far as to give the company special speed approval for their newest genetically engineered seed varieties. It turns out that Monsanto was not getting quick enough approval for their crops, which have been linked to severe organ damage and other significant health concerns.
Steve Censky, chief executive officer of the American Soybean Association, states it quite plainly. It was a move to help Monsanto and other biotechnology giants squash competition and make profits. After all, who cares about public health?
“It is a concern from a competition standpoint,” Censky said in a telephone interview.
It appears that when Monsanto cannot answer for their environmental devastation, they buy up a company that may potentially be their ‘experts’ in denying any such link between their crops and the bee decline.
Government tyranny: Illinois Department of Agriculture secretly destroys beekeeper’s bees and 15 years of research proving Monsanto’s Roundup kills bees.
Full Article: An Illinois beekeeper with more than a decade’s worth of expertise about how to successfully raise organic, chemical-free bees is the latest victim of flagrant government tyranny. According to the Prairie Advocate, Terrence “Terry” Ingram of Apple River, Ill., owner of Apple Creek Apiaries, recently had his bees and beehives stolen from him by the Illinois Department of Agriculture (ID of A), as well as more than 15 years’ worth of research proving Monsanto’s Roundup to be the cause of Colony Collapse Disorder (CCD) destroyed.
It began last summer when Ingram, who teaches children about natural beekeeping, gave a sample of his honeycomb to IDofA inspector Susan Kivikko (http://www.agr.state.il.us/programs/bee ... ctors.html) at a beekeeper’s picnic. Ingram explained that his bees would not touch the comb, and asked Kivikko if it could be tested for chemical contamination.
Kivikko told him that IDofA does not test for chemicals, presumably because its policy is to actively promote them, and instead took the comb and had it tested for “foulbrood,” a disease that Ingram says is greatly overblown. When the test allegedly came back positive, Kivikko proceeded to get the ball rolling on a witch hunt that would eventually lead to the illegal seizure and destruction of Ingram’s personal property.
Not only did Kivikko, as well as her colleague Eleanor Balson and superior Steven D. Chard, break the law by trespassing Ingram’s property on numerous occasions without a warrant, but they also committed numerous crimes by stealing his hives and equipment and destroying pertinent evidence before a hearing, which Ingram believes may have ultimately been rooted in a deliberate conspiracy by the state to hide the truth about Roundup, and subsequently steal his most vibrant bees.
Of particular interest was Ingram’s extensive research on Monsanto’s Roundup herbicide, which began several years ago when hundreds of Ingram’s hives had died. He later determined that Roundup sprayings near his property were to blame, which prompted him to actively research the subject and closely monitor his hives in conjunction with this research from that point onward.
What he gathered, and subsequently taught to others, was concrete evidence that Roundup kills bees. He also used this information and his many years of experience to develop and refine ways of growing strong, chemical-free bees in spite of Roundup sprayings, a move that apparently upset ID of A, which operates primarily to serve the interests of chemical companies rather than the interests of the people.
“Is Illinois becoming a police state, where citizens do not have rights?” asked Ingram, who has been deliberately denied his rights, to the Prairie Advocate. “Knowing that Monsanto and the Department of Agriculture are in bed together, one has to wonder if Monsanto was behind the theft to ruin my research that may prove Roundup was, and is, killing honeybees.”

Here we go again. Yet more research has been published in the world's most prestigious, peer-reviewed journals showing that extremely widely-used pesticides have very damaging effects on bees, yet the only response from the government is inaction.
The new paper, published in Nature, shows that bumblebees foraging naturally and exposed to realistic doses of pesticides suffer in two key ways. First they are about twice as likely to die: two-thirds of the bees are lost when exposed to two pesticides compared to only a third when not exposed. Second, the exposed bees are half as successful in gathering food.
The new results reveal, again, shameful failings in the regulatory regime. The ecotoxicology tests currently required only look at honey bees. Yet bumblebees, the subject of the new research, are just as important in providing the pollination that creates much of the food we eat. Tomatoes, for example, rely on bumblebees. Furthermore, bumblebees are very different, bigger in size individually, but living in colonies of just dozens, compared to the tens of thousands in honey bee colonies.
Another failing is that current tests require just 96 hours of exposure, but the new research only saw the damaging effect after three weeks. "If we had done our study for just 96 hours, our conclusions would have been very different," says Nigel Raine, at Royal Holloway, University of London, one of the research team.
Yet another failing is that pesticides are only tested individually, not in the combination bees are exposed to in reality. The new work clearly shows a damaging cumulative effect from a combination of just two pesticides.
The reaction from pesticide manufacturers is the same as ever: the experiments are "unrealistic". Raine rejects this: "It is hard to see what you could do better." I think he has a point. The only truly "realistic" experiment would have no intervention at all, meaning you could collect no data. The manufacturers are making the perfect the enemy of the good. They also claim their own data shows there are no harmful effects, yet have not published it.
The manufacturers do have some scientists supporting their view that there is too little evidence of harm to act. James Cresswell, an ecotoxicologist at the University of Exeter, said:" It certainly wouldn't be fair to say that this research spells doom for wild bees."
Creswell also criticised research published the journal Science in March, which showed that honeybees consuming one pesticide suffered an 85% loss in the number of queens their nests produced. Subsequently, Creswell was granted £136,000 by pesticide manufacturer Syngenta to fund a research post. Cresswell said there was no connection between the two. "I consider myself an impartial scientist," he told me, adding he had not spoken to Syngenta until after his criticism was sent to Science.
The UK government has already reviewed some of the evidence of the serious harm pesticides cause to bees but, unlike other countries, chose to do nothing. But parliament is now investigating the issue, with the call for evidence open until 2 November.
"Ministers may want to start doing their homework on pesticide policy and biodiversity, because we will be calling them before parliament to answer questions," said Joan Walley MP, chair of the Environmental Audit Committee, when announcing the enquiry. "In particular, we will be scrutinising the evidence behind the government's decision not to revise pesticide regulations or follow other European countries in temporarily suspending the use of insecticides linked to bee decline."
The questions are mounting: this latest research shows the need for answers is becoming ever more urgent.
Bee-harming pesticides escape European ban
European commission proposal to suspend the use of neonicotinoids fails to gain backing of UK and Germany

The world's most widely used insecticides, linked to serious harm in bees, will not be banned across Europe. The European commission proposed a two-year suspension after the European Food Safety Authority deemed the use of the neonicotinoids an unacceptable risk, but major nations – including UK and Germany – failed to back the plan in a vote on Friday.
The result leaves environmental campaigners, scientists and some politicians bitterly disappointed. "Britain and Germany have caved in to the industry lobby and refused to ban bee-killing pesticides," said Iain Keith, at campaign group Avaaz. "Today's vote flies in the face of science and public opinion and maintains the disastrous chemical armageddon on bees, which are critical for the future of our food." He said Avaaz and other groups would now consider a legal challenge.
The chemical companies that dominate the billion-dollar neonicotinoid market, Bayer and Syngenta, will be relieved, as will the UK government. Ministers had argued that more scientific evidence was needed and that a ban could have caused disproportionate damage to food production.
Conservationists argued that even greater harm results from the loss of bees and the vital pollination service they provide. Almost three-quarters of the UK public backed the proposed ban, according to a poll released on Wednesday, and Avaaz had amassed 2.5m signatures across Europe in support.
EC officials said: "The commission takes note of the member states' response to its proposal but remains committed to ambitious and proportionate legislative measures."
Suspensions have previously been put in place in France, Germany, Italy and Slovenia, but the EC proposal would have applied across all 27 member states. Friday's vote by member states' experts on the standing committee on the food chain and animal health failed to reach the required majority either in favour or against the suspension.
About three-quarters of global food crops rely on bees and other insects to fertilise their flowers, and so the decline of honeybee colonies due to disease, habitat loss and pesticide harm has prompted serious concern.
A series of high-profile scientific studies in the last year has increasingly linked neonicotinoids to harmful effects in bees, including huge losses in the number of queens produced, and big increases in "disappeared" bees – those that fail to return from foraging trips.
The UK's environment secretary, Owen Paterson, faced criticism from one of his Conservative predecessors. Lord Deben, who as John Gummer was environment secretary, said: "If ever there were an issue where the precautionary principle ought to guide our actions, it is in the use of neonicotinoids. Bees are too important to our crops to continue to take this risk."
Paterson had said in February: "I have asked the EC to wait for the results of our field trials, rather than rushing to a decision." However, the results were not available at Friday's meeting because the field trials have been seriously compromised by contamination from neonicotinoids, the world's most widely used insecticide. Prof Ian Boyd, Defra's chief scientist, said: "At the control site, there were residues of neonicotinoids in pollen and nectar."
Green MEPs across Europe had written to every nation's environment minister, including Paterson. "By spreading uncertainty via apparently 'science-based' arguments, the agrochemical companies are acting as 'merchants of doubt' and are therefore blocking effective action by European policymakers," said the letter.
The EC proposal was to ban the use of three neonicotinoids from use on corn, oil seed rape, apples, carrots, strawberries and many other flowering crops across the continent for two years, after which the situation would have been reviewed.
Evidence submitted to an ongoing parliamentary inquiry in the UK cites a long list of failings in the existing regulation of neonicotinoids. Currently, only the effects on honeybees are considered, despite 90% of pollination being performed by different species, such as solitary or bumblebees, hoverflies, butterflies, moths and others. Another failing is that the regime was set up for pesticide sprays, not systemic chemicals like neonicotinoids that are used to treat seeds and then spread through the growing plant.
Even the National Farmers Union, which argues that there is no need for change, admitted: "It is very well-known that the current pesticide risk assessment systems for bees were not developed to assess systemic pesticides."

US government sued over use of pesticides linked to bee harm
Beekeepers, conservation and food campaigners accuse Environmental Protection Agency of failing to protect the insects

The US government is being sued by a coalition of beekeepers, conservation and food campaigners over pesticides linked to serious harm in bees.
The lawsuit accuses the Environmental Protection Agency (EPA) of failing to protect the insects – which pollinate three-quarters of all food crops – from nerve agents that it says should be suspended from use. Neonicotinoids, the world's most widely used insecticides, are also facing the prospect of suspension in the European Union, after the health commissioner pledged to press on with the proposed ban despite opposition from the UK and Germany.
"We have demonstrated time and time again over the last several years that the EPA needs to protect bees," said Peter Jenkins, an attorney at the Centre for Food Safety who is representing the coalition. "The agency has refused, so we've been compelled to sue."
"America's beekeepers cannot survive for long with the toxic environment EPA has supported," said Steve Ellis, a Minnesota and California beekeeper and one of the plaintiffs who filed the suit at the federal district court. "Bee-toxic pesticides in dozens of widely used products, on top of many other stresses our industry faces, are killing our bees."
The EPA declined to comment on the lawsuit, but said in a statement: "We are working aggressively to protect bees and other pollinators from pesticide risks through regulatory, voluntary and research programmes. Specifically, the EPA is accelerating the schedule for registration review of the neonicotinoid pesticides because of uncertainties about them and their potential effects on bees." However, even the accelerated review will not be completed before 2018.
The pesticides named in the lawsuits are clothianidin, manufactured by Bayer, and thiamethoxam, made by Syngenta. Neither company chose to comment on the lawsuit, but industry group Crop Life America (CLA) is representing some of the companies.
"The CLA fully supports and trusts the rigour of EPA's review process for crop protection products, including neonicotinoids," said Ray McAllister, senior director of regulatory affairs at CLA. "This class of product represents an important component of modern agriculture that helps farmers protect their crops. Neonicotinoids are thoroughly tested and monitored for potential risks to the environment and various beneficial species, including honeybees."
A series of high-profile scientific studies in the last year have increasingly linked neonicotinoids to harmful effects in bees, including huge losses in the number of queens produced, and big increases in "disappeared" bees that fail to return from foraging trips. Disease and habitat loss are also thought to be factors in the recent declines in populations of bees and other pollinators.
A proposal to suspend the use of three neonicotinoids across the EU ended in a hung vote on 15 March. But Tonio Borg, the European commissioner for health and consumer policy, said this week he would take the proposal to appeal. If member states maintained their positions, the insecticides would be suspended. "The health of our bees is of paramount importance," said Borg. "We have a duty to take proportionate yet decisive action to protect them wherever appropriate."
The lawsuit against the EPA argues that, via "conditional registrations", the regulator rushed the neonicotinoids into the market without sufficient examination and since that time has failed to take account of new information. "Pesticide manufacturers use conditional registrations to rush bee-toxic products to market, with little public oversight," said Paul Towers, at Pesticide Action Network, part of the coalition.
The action by the coalition, which also includes the Sierra Club and the Centre for Environmental Health, follows an emergency petition in March 2012 which demanded the EPA suspend the use of clothianidin but was not acted upon. Also issued this week was a report from the American Bird Conservancy, which said the "EPA risk assessments have greatly underestimated [the risk to birds], using scientifically unsound, outdated methodology."
Scientists discover what’s killing the bees and it’s worse than you thought

As we’ve written before, the mysterious mass die-off of honey bees that pollinate $30 billion worth of crops in the US has so decimated America’s apis mellifera population that one bad winter could leave fields fallow. Now, a new study has pinpointed some of the probable causes of bee deaths and the rather scary results show that averting beemageddon will be much more difficult than previously thought.
Scientists had struggled to find the trigger for so-called Colony Collapse Disorder (CCD) that has wiped out an estimated 10 million beehives, worth $2 billion, over the past six years. Suspects have included pesticides, disease-bearing parasites and poor nutrition. But in a first-of-its-kind study published today in the journal PLOS ONE, scientists at the University of Maryland and the US Department of Agriculture have identified a witch’s brew of pesticides and fungicides contaminating pollen that bees collect to feed their hives. The findings break new ground on why large numbers of bees are dying though they do not identify the specific cause of CCD, where an entire beehive dies at once.
When researchers collected pollen from hives on the east coast pollinating cranberry, watermelon and other crops and fed it to healthy bees, those bees showed a significant decline in their ability to resist infection by a parasite called Nosema ceranae. The parasite has been implicated in Colony Collapse Disorder though scientists took pains to point out that their findings do not directly link the pesticides to CCD. The pollen was contaminated on average with nine different pesticides and fungicides though scientists discovered 21 agricultural chemicals in one sample. Scientists identified eight ag chemicals associated with increased risk of infection by the parasite.
Most disturbing, bees that ate pollen contaminated with fungicides were three times as likely to be infected by the parasite. Widely used, fungicides had been thought to be harmless for bees as they’re designed to kill fungus, not insects, on crops like apples.
“There’s growing evidence that fungicides may be affecting the bees on their own and I think what it highlights is a need to reassess how we label these agricultural chemicals,” Dennis vanEngelsdorp, the study’s lead author, told Quartz.
Labels on pesticides warn farmers not to spray when pollinating bees are in the vicinity but such precautions have not applied to fungicides.
Bee populations are so low in the US that it now takes 60% of the country’s surviving colonies just to pollinate one California crop, almonds. And that’s not just a west coast problem—California supplies 80% of the world’s almonds, a market worth $4 billion.
In recent years, a class of chemicals called neonicotinoids has been linked to bee deaths and in April regulators banned the use of the pesticide for two years in Europe where bee populations have also plummeted. But vanEngelsdorp, an assistant research scientist at the University of Maryland, says the new study shows that the interaction of multiple pesticides is affecting bee health.
“The pesticide issue in itself is much more complex than we have led to be believe,” he says. “It’s a lot more complicated than just one product, which means of course the solution does not lie in just banning one class of product.”
The study found another complication in efforts to save the bees: US honey bees, which are descendants of European bees, do not bring home pollen from native North American crops but collect bee chow from nearby weeds and wildflowers. That pollen, however, was also contaminated with pesticides even though those plants were not the target of spraying.
“It’s not clear whether the pesticides are drifting over to those plants but we need take a new look at agricultural spraying practices,” says vanEngelsdorp.
