Perils of commercial beekeeping

Honeybees pollinate crops but endure stress, parasites and disease. Solutions are coming. 

Paul Driessen

One of America’s earliest food crops – almonds – is also one of the most important for commercial beekeepers. Almonds depend on bees for pollination, but the explosive growth of this bumper crop taxes the very honeybees the industry needs to thrive.
California’s Central Valley produces over 80% of the world’s almonds, valued at over $4 billion in 2012. The boom is poised to continue, with new food products and expanding overseas markets increasing demand to the point that no young almond trees are available for purchase until 2016.
Demand for almonds translates into demand for pollination. So every year commercial beekeepers transport some 60% of all US honeybees to California’s almond groves in February and March, when it’s still winter in most other states. It’s one of their biggest challenges.
For one thing, bee colonies, especially those from northern states, lack sufficient time to emerge from their heat-conserving winter clusters. Some beekeepers thus maintain 20,000 to 30,000 hives. Each one requires careful inspection for diseases and parasites – a meticulous, Herculean task on such a scale.
Complicating the situation, beekeepers are trying to work within a large-scale agricultural system, using an insect whose husbandry practices have changed little since the nineteenth century. The larger the commercial beekeeper’s stock, the harder it can be to tend them and recover from financial setbacks in the form of lost bees.
Almond growers will need 1.5 million hives this year, estimates Colorado beekeeper Lyle Johnston. “It takes almost all the commercial bees in the United States,” to pollinate the almond crop, he says. The payoff can amount to half an individual keeper’s yearly profit.
However, bees can come back from California “loaded with mites and every other disease you can think of,” beekeeper Ed Colby explains. That can often mean bee colony deaths. Last year, US beekeepers experienced an average 30% overwinter bee loss; some lost 10% to 15% of their hives, while others lost much more. It’s a normal cost of doing business, but it can be painful.
Last year’s rate was higher than normal, and higher than any keeper would want. But it was not the “bee-pocalypse” that some news stories claimed. The real story is that efforts to identify a single unifying cause for higher-than-usual losses have failed. Scientists are discovering that multiple issues affect bee health.
Urban, suburban and agricultural “development has reduced natural habitats, clearing out thousands of acres of clover and natural flowers,” a 60 Minutes investigative report observed. “Instead, bees are spending week after week on the road, feeding on a single crop, undernourished and overworked.”
The migration itself is stressful, notes Glenwood Springs, Colorado Post-Independent reporter Marilyn Gleason. “First, there’s the road trip, which isn’t exactly natural for bees, and may include freezing cold or scorching heat. Bees ship out of Colorado before the coldest weather, and drivers may drench hot, thirsty bees with water at the truck wash.”
The convergence in almond groves of so many commercial bees from all over the country creates a hotbed of viruses and pathogens that can spread to many hives. The varroa destructor mite carries at least 19 different bee viruses and diseases, causing major impacts on bee colonies. Parasitic phorid flies are another problem, and highly contagious infections also pose significant threats. The intestinal fungus nosema ceranae, for example, prevents bees from absorbing nutrition, resulting in starvation.
The tobacco ringspot virus was likewise linked recently to the highly publicized problem known as “colony collapse disorder.” CCD occurs when bees in a colony disappear, leaving behind only a queen and a few workers. The term originally lumped together a variety of such “disappearing” disorders recorded in different locales across hundreds of years, as far back as 950 AD in Ireland. Thankfully, as during past episodes, these unexplained incidents have declined in recent years and, despite all these challenges, overall US honeybee populations and the number of managed colonies have held steady for nearly 20 years.
These days, perhaps the biggest existential threat to bees is campaigns purporting to save them. Extreme-green groups like the Center for Food Safety and Pesticide Action Network of North America are blaming an innovative new class of pesticides called neonicotinoids for both over-winter bee losses and CCD.
Allied with several outspoken beekeepers, the activists are pressuring the Environmental Protection Agency, Canada’s Pest Management Regulatory Agency and government regulatory agencies to follow Europe’s lead – and ban neonics. Instead of protecting bees and beekeepers, however, their campaigns will likely cause greater harm – because they ignore the multiple threats that scientists have identified, and because a neonic ban will result in farmers using pesticides that are more toxic to bees.
The European Union’s political decision to suspend neonic use came because France’s new agriculture minister banned their use. That meant French farmers would be at a distinct disadvantage with the rest of Europe, if they were the only ones unable to use the pesticide, noted British environmental commentator Richard North. They could lose $278 million per season in lost yields and extra pesticide spraying.
So the French agricultural ministry sought an EU-wide ban on all neonicotinoids. After several votes and a misleading report on the science, the European Commission imposed a ban, over the objections of many other EU members, who note that the evidence clearly demonstrates the new pesticides are safe for bees.
Years-long field tests have found that real-world exposures have no observable effects on bee colonies. Other studies have highlighted other significant insect, fungal, human and other issues that, singly or collectively, could explain CCD. Having analyzed scores of 2007-2012 bee death incidents, Canadian bee experts concluded that “…very few of the serious bee kills involve neonicotinoid pesticides. Five times as many ‘major’ or ‘moderate’ pesticide-related bee kills were sourced to non-neonic chemicals.”
In Canada’s western provinces, almost 20 million acres of 100% neonic-treated canola is pollinated annually by honeybees and tiny alfalfa leaf-cutter bees. Both species thrive on the crop, demonstrating that neonics are not a problem. Large-scale field studies of honeybees at Canadian universities and a bumblebee field study by a UK government agency found no adverse effects on bees.
Last October, a team of industry scientists published a four-year study of the effects of repeated honeybee exposure to neonic-treated corn and rapeseed (canola) pollen and nectar under field conditions in several French provinces. The study found similar mortality, foraging behavior, colony strength and weight, brood development and food storage in colonies exposed to seed-treated crops and in unexposed control colonies. This also indicates low risk to bees.
At least two more major, recently completed university-run field research projects conducted under complex, costly scientific laboratory guidelines (“good lab practices”) are awaiting publication. All indications to date suggest that they too will find no observable adverse effects on bees at field-realistic exposures to neonicotinoids.
Meanwhile Project ApisM., a partnership of agro-businesses and beekeepers, has invested $2.5 million in research to enhance the health of honeybee colonies. Switzerland-based Syngenta has spent millions expanding bee habitats in Europe and North America, through Project Pollinator. Bayer has built bee health centers in Europe and the United States, and Monsanto’s Beeologics subsidiary is developing technology to fight varroa mites.
None of that matters to the anti-pesticide activists. They are using pressure tactics to make Canada and the United States copy the EU. That would be a huge mistake. Science, not politics, should prevail.

BC Deer Protection Society should pay for damages



As a former Conservation Officer that had to deal with the aftermath of deer/human interaction, I applaud the efforts of councils to cull the deer population, it’s long overdue and needs to continue.  It’s a necessary part of wildlife population management. The attacks on people and pets are well documented in communities throughout BC and a cull is the only option that is viable. Deer do not belong on urban streets and in backyards. They have ample room to habituate outside of the communities.  All the rhetoric about “they were here first” is historically wrong. The early explorers  of this area wrote of lean times trying to find wildlife to hunt.  It’s only been thru proper management and continuing efforts of hunters and conservationists that deer have been allowed to thrive in the Kootenays.

It’s been over a month since Kazakoff and Sikora were charged and released for their alleged part in tampering of deer traps in Kimberley.  The BC Deer Protection Society’s (BCDPS ) only response is to ask for donations to fight the charges against their spokesperson. The societies act is fairly clear that donations have to be used to further the goals of the organization. In my view this is clearly outside of a not for profit society function. The directors of the BCDPS should be the ones paying not the general public. Are they condoning criminal actions while building a war chest for future actions? Instead of a defense fund the BCDPS should pay for the damaged traps and the contractors lost wages? It’s only fair considering all the financial damage they have inflicted on municipalities and individuals.

Anti Deer Cull groups need to come clean


Devin Kazakoff protesting in Cranbrook 2013
Devin Kazakoff spokesperson for the BC Deer Protection Society (BCDPS) and the Invermere Deer Protection Society (IDPS), has been charged with mischief, and disguising the face with intent to commit an offence.  Kazakoff and co accused Lucky Gene Sikora were alleged to have tampered with the deer traps in Kimberley on Feb 27th. Kazakoff and Sikora are enabled by multiple anti deer cull groups across BC and a registered political party in Ontario the Animal Alliance and Environmental Voters Party. Animal Alliance is run from Ontario by Liz White, the BCDPS is headed by Colleen Bailey of Cranbrook of which Kazakoff is a spokesperson, Kazakoff and Vince Zurbriggen are on record as the founders of the IDPS. These activists all share a common goal under the BC Deer Protection Coalition (BCDPC) giving themselves internal support and a larger donation base.
BCDPS spokesperson Kazakoff has been decrying the secrecy of councils by day while under cover of darkness he was allegedly wearing a mask to tamper with traps. Neither Liz White of the Animal Alliance or Coleen Bailey, head of the BCDPS have made any official statement to the media about the arrest of the BCDPS spokespersons.  Is the BCDPS shifting gears and adopting a Greenpeace style of activism?
The BCDPS, BCDPC and the Animal Alliance have had ample time to make a public statement about Kazakoff and Sikora. Ms. White and Bailey need to be reminded that it is their spokesperson that is facing serious criminal charges, have they nothing to say?  Colleen Bailey and Liz White have taken the time to post comments or articles on various media sources since the arrest but neither makes any mention of Kazakoff’s arrest.  They need to publically condemn what Kazakoff’s is alleged to have done.  Failure to do so could send these various deer protection groups down the road of eco-activism; embracing criminal activity to achieve their goals.
Is this really want  Colleen Bailey and Liz White want?
