Two neonics set for three-year extensions on registration
Health Canada’s pesticide regulator proposes to allow continued registration for two members of the neonicotinoid family of pesticides, both of which are under heavy scrutiny for their effects on bees and other pollinators. The Pest Management Regulatory Agency on Tuesday issued proposed decisions on clothianidin and thiamethoxam that would extend the products’ existing conditional registrations […] Read more
French court suspends pesticides over potential harm to bees
Paris | Reuters — A French court suspended on Friday the licence for two pesticides made by Dow Chemical, citing uncertainty over environmental risks including their effects on bees.

Data mining finds no honeybee colony risk from correct neonic use
An expedition through published and unpublished studies on neonicotinoid pesticides has led a Guelph research team to find no colony-level risk to honeybees from the seed treatments — if they’re correctly used. The University of Guelph team, led by toxicologist Keith Solomon and adjunct professor Gladys Stephenson, analyzed 64 papers from “open, peer-reviewed literature” on […] Read more
U of S research reveals controversial insecticides are toxic to songbirds
Saskatoon – Research at the University of Saskatchewan (U of S) has linked the use of insecticides to serious health issues in songbirds. “Studies on the risks of neonicotinoids have often focused on bees that have been experiencing population declines. However, it is not just bees that are being affected by these insecticides,” said Christy […] Read more
Global study finds trace neonics in much of world’s honey
A study by Swiss scientists has found trace levels of at least one neonicotinoid pesticide in three-quarters of the honey samples it collected from around the world. The study, spearheaded by a team from Switzerland’s Universite de Neuchatel and published in Friday’s edition of the journal Science, was meant to assess “global exposure of pollinators […] Read more
Field studies fuel dispute over whether neonics harm bees
London | Reuters — Two major studies into how bees are affected by a group of pesticides banned in Europe gave mixed results on Thursday, fuelling a row over whether the neonicotinoid pesticides are safe.

Long-term U.K. study links neonics to wild bee declines
London | Reuters — Wild bees that forage from oilseed rape crops treated with insecticides known as neonicotinoids are more likely to undergo long-term population declines than bees that forage from other sources, according to the findings of an 18-year study. The new research covered 62 species of bee found in the wild in Britain […] Read more
