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.
