The U.S. Environmental Protection Agency last week denied a legal petition by Center for Food Safety, Pesticide Action Network of North America and others, demanding that the agency fix its failure to regulate pesticide-coated seeds, which are known to be widely harming bees and other pollinators.Last week, the U.S. Environmental Protection Agency (EPA) denied a legal petition by Center for Food Safety (CFS), Pesticide Action Network of North America and others, demanding that the agency fix its failure to regulate pesticide-coated seeds, which are known to be widely harming bees and other pollinators.These crop seeds are coated with systemic insecticides...

**snip**Bees and other pollinators have been on the decline for more than a decade and experts blame a combination of factors: neonics, parasites, disease, climate change and lack of a diverse food supply. Honeybees don't just make honey; about one-third of the human diet comes from plants that are pollinated by the insects. Bees pick up the pesticide when they feed on fields grown from treated seeds. **snip**"What this shows is the magnitude of the contamination," said study lead author Edward Mitchell, a biology professor at the University of Neuchatel in Switzerland, adding that there are "relatively few places where...

A new study finds that a commonly used insecticide kills much of the sperm created by male drone honey bees, one reason why the bees are dwindling. The class of insecticide called neonicotinoids didn’t kill the drones. But bees that ate treated pollen produced 39 percent less live sperm than those that didn’t, according to a controlled experiment by Swiss researchers published Wednesday in the journal Proceedings of the Royal Society B. It essentially acted as an accidental contraceptive on the drones, whose main job is to mate with the queen — but not one that prevented complete reproduction, just...

A federal appeals court this week assailed the Environmental Protection Agency for approving a Dow AgroSciences insecticide linked to honeybee deaths, charging that the agency's action was based on flawed and inadequate data. The decision by a three judge panel in San Francisco was a huge win for beekeepers who have argued that the new type of insecticide targeted in the case one of the causes of "Colony Collapse Disorder" blamed for the deaths of millions of hives. It was a huge blow to Dow, which touted its pesticide Sulfoxaflor to investors. The company's stock took a hit on Wall...

Over 100 scientists worldwide, citing 800 studies, are demanding that the Obama administration follow Europe’s lead and put a moratorium on the use of a new-style pesticide blamed for the deaths of 30 percent of American honeybees every year. In a letter to the EPA and Agriculture Department, the scientists said there is overwhelming evidence from 800 studies that the pesticide family called neonicotinoids are to blame for the substantial declines in honeybees, bumblebees and butterflies, all pollinators needed to help farmers produce billions of dollars worth of food every year. “The 108 signers of this letter therefore urge you...

The mysterious vanishing of honeybees from hives can be directly linked to insectcide use, according to new research from Harvard University. The scientists showed that exposure to two neonicotinoids, the world's most widely used class of insecticide, lead to half the colonies studied dying, while none of the untreated colonies saw their bees disappear. "We demonstrated that neonicotinoids are highly likely to be responsible for triggering 'colony collapse disorder' in honeybee hives that were healthy prior to the arrival of winter," said Chensheng Lu, an expert on environmental exposure biology at Harvard School of Public Health and who led the...

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...

Three neonicotinoid insecticides are to be banned from use on crops that attract bees for two years in the EU. This follows a vote by member states yesterday. Although the final vote did not reach the majority needed for legislation to pass, the hung result allows the commission to decide further action. Tonio Borg, health and consumer commissioner, made it clear in a statement that the ban will proceed, citing a study by the European Food Safety Authority, published in January, that concluded that the pesticides posed a ‘high acute risk’ to pollinators, including honeybees. Applying clothianidin, imidacloprid and thiametoxam...

Europe is on the brink of a landmark ban on the world's most widely used insecticides, which have increasingly been linked to serious declines in bee numbers. Despite intense secret lobbying by British ministers and chemical companies against the ban, revealed in documents obtained by the Observer, a vote in Brussels on Monday is expected to lead to the suspension of the nerve agents. Bees and other insects are vital for global food production as they pollinate three-quarters of all crops. The plummeting numbers of pollinators in recent years has been blamed on disease, loss of habitat and, increasingly, the...

Scientists have been alarmed and puzzled by declines in bee populations in the United States and other parts of the world. They have suspected that pesticides are playing a part, but to date their experiments have yielded conflicting, ambiguous results. In Thursday’s issue of the journal Science, two teams of researchers published studies suggesting that low levels of a common pesticide can have significant effects on bee colonies. One experiment, conducted by French researchers, indicates that the chemicals fog honeybee brains, making it harder for them to find their way home. The other study, by scientists in Britain, suggests that...
