Scientists from the U.S. Geological Survey found neonicotinoid insecticides in 74 percent of the water samples they analyzed from 10 major tributaries of the Great Lakes. The insecticides were "detected in every month sampled and five of the six target neonicotinoids were detected." Environmental Health News says the study "suggests the Great Lakes' fish, birds and entire ecosystems might be at risk" from the insecticides that are believed to be a factor in high mortality rates of honeybees.
Wild bumblebee queens exposed to neonicotinoid pesticides were 26 percent less likely to lay eggs than unexposed queens, says a study published in the journal Nature Ecology and Evolution.
Two new farm-based studies have provided some of the most compelling evidence to date that neonicotinoid pesticides are harmful to domestic and wild bees.The first study, paid for in part by $3 million from Syngenta and Bayer and published in the journal Science, “took place at 33 large farmland sites spread across the UK, Germany and Hungary.
The head of Donald Trump’s EPA transition team, Myron Ebell, is not only a climate-change skeptic. He also has a history of discouraging pesticide regulations, writes Tom Philpott at Mother Jones, pointing to Ebell's role as the director of the Center for Energy and Environment at the Competitive Enterprise Institute (CEI).
With the widespread adoption of genetically engineered crops — accounting for 94 percent of all soybeans and 93 percent of all corn in the U.S. in 2015 — the use of the herbicides rose, although insecticide use in corn declined, according to a new study published in the journal Science.
The level of neonicotinoid pesticides found on plants sold by large retailers to gardeners dropped to 23 percent this spring, according to a survey that looked at garden plants in 14 U.S. cities. In 2013 and 2014, neonicotinoid residue was found on more than half of the samples taken. Some experts blame the class of pesticides for Colony Collapse Disorder and other detrimental effects on pollinators.
