As massive numbers of bees and other pollinators keep dying across the globe, study after study continues to connect these deaths to neonicotinoid pesticides (A.K.A. "neonics"). With the science piling up, and other countries starting to take critical pollinator-saving action, here's a quick primer on all things neonics:

The Center for Biological Diversity Thursday urged the U.S. Environmental Protection Agency to deny Bayer CropScience's request to allow the highly bee-toxic pesticide flupyradifurone to be sprayed on tobacco in states like Kentucky and North Carolina.
The Trump administration has lifted an Obama-era ban on the use of genetically modified crops and pesticides linked to bee decline in certain national wildlife refuges where farming is allowed, Reuters reported Saturday.

But a new study from the University of Guelph finds that honeybees aren't the only non-pest creatures that are coming into contact with the pesticides.

A major global assessment of global bird populations paints a grim outlook for our feathered friends.
A new report from BirdLife International finds that 40 percent of the world's 11,000 bird species are in decline, with one in eight bird species now under some threat of extinction.
Monday, the Washington Department of Ecology sided with Center for Food Safety and numerous other community and conservation groups, and denied shellfish growers a permit to spray imidacloprid, a neonicotinoid, on shellfish beds on Willapa Bay and Grays Harbor, in southwest Washington. The requested permit would have allowed shellfish growers from Willapa-Grays Harbor Oyster Growers Association to spray this neurotoxic insecticide into water for the first time, in order to kill native burrowing shrimp.

A study published Thursday in Current Biology is being hailed in a University of Exeter press release as a major "breakthrough" in developing bee-friendly insecticides. But some environmentalists think the research is asking the wrong questions to begin with.

The European Food Safety Authority (EFSA) concluded in a new assessment that "most uses" of three widely used neonicotinoids—imidacloprid, clothianidin and thiamethoxam—pose a risk to wild bees and honeybees, which play a crucial role in pollination across the globe.
The conclusion, based on analysis of more than 1,500 studies, will likely prompt a total ban on the pesticides from all fields across the European Union when the issue comes to a vote next month, the Guardian reported.
Conservation Groups, House Reps Call for EPA to Respect Science, Take Action on Pollinator-Killing Pesticides
Congressman Earl Blumenauer (D.-Ore.), alongside Representative Jim McGovern (D.-Mass.) and conservation, farmworker, farmer and consumer groups, on Wednesday reintroduced the Saving America's Pollinators Act, which aims to suspend the registration of certain neonicotinoid insecticides until the U.S. Environmental Protection Agency (EPA) conducts a full scientific review.
In addition, 16 environmental and conservation groups have collected more than 100,000 public comments urging the agency to rein in the rampant overuse of neonicotinoid pesticides—a leading cause of pollinator population declines.
The Canadian government is banning plastic microbeads in toiletries. Although designed to clean us, they're polluting the environment, putting the health of fish, wildlife and people at risk. Manufacturers and consumers ushered plastic microbeads into the marketplace, but when we learned of their dangers, we moved to phase them out.
Why, then, is it taking so long to phase out the world's most widely used insecticides, neonicotinoids? Scientists have proven they're harming not only the pests they're designed to kill, but also a long list of non-target species, including pollinators we rely on globally for about one-third of food crops.

Raising further concerns about the global food production system, a new study found that bees worldwide are being widely exposed to dangerous agricultural chemicals, with 75 percent of honey samples from six continents testing positive for pesticides known to harm pollinators.
"What this shows is the magnitude of the contamination," the study's lead author, Edward Mitchell, a biology professor at the University of Neuchatel in Switzerland, told the Denver Post. He said there were "relatively few places where we did not find any" contaminated samples.
Neonicotinoids, a common and highly controversial class of insecticides linked to catastrophic bee deaths, could be significantly lowering the sperm count of male drone honey bees and cutting their life span by a third, Swiss researchers found.
Researchers from the Institute of Bee Health at the University of Bern, Switzerland discovered that male drone honeybees that ate pollen treated with two popular "neonics"—thiamethoxam and clothianidin—produced nearly 40 percent less sperm than those that did not.
