Scientists at UBC are unravelling the mysteries behind a persistent problem in commercial beekeeping that is one of the leading causes of colony mortality — queen bee failure. This occurs when the queen fails to produce enough fertilized eggs to maintain the hive, and is regularly cited by the Canadian Association of Professional Apiarists as … More Scientists find clues to queen bee failure.
The reddish-brown varroa mite, a parasite of honeybees and accidentally introduced in the Big Island of Hawaii in 2007-08, is about the size of a pinhead. Yet, its effects there are concerning to entomologists because the mite is found nearly everywhere honeybees are present. A team led by entomologists at the University of California, Riverside, … More Bee mite arrival in Hawaii causes pathogen changes in honeybee predators.
A coalition that includes Environmental Defence and the Ontario Beekeepers Federation says proposed rule changes for neonicotinoids, or neonics for short, will make it easier for farmers to use them and harder for the government to track them. But the Ontario government, farmer organizations and pesticide manufacturers who support the changes say they would reduce … More Environmental groups say the Ontario government is proposing to weaken the province’s restrictions on a class of agricultural pesticides that some scientific studies blame for large declines in the populations of bees and other insects.
The immediate “no-regret” measures they propose include aggressively curbing planet-heating emissions and the use of synthetic pesticides. by Jessica Corbett, staff writer Highlighting the “strong scientific consensus that the decline of insects, other arthropods, and biodiversity as a whole, is a very real and serious threat that society must urgently address,” 73 international scientists on … More ‘Because Insects Are Key to Our Own Survival,’ 73 Scientists Unveil Global Road map to Battle Bugpocalypse.
The situation is dire with massive bee die offs — largely thanks to the continued use of bee-killing pesticides. Thankfully, the Saving America’s Pollinators Act (SAPA) would put a stop to these toxic chemicals. Scientists have warned that further decline of bees and other insects could lead us to a “collapse of nature’s ecosystems.” Currently, 40 percent of wild bees and other … More The numbers are in: Beekeepers faced their second highest losses in 14 years this past year.
They show beekeepers lost 44 percent of their colonies. This makes 2019 the second-worst year for bees since the surveys started almost 15 years ago. Bees pollinate 75% of our food crops. With their populations rapidly declining — largely thanks to toxic pesticides — we need all hands on deck to protect them and other … More BREAKING NEWS: This year’s bee die-off numbers were just reported.
During the past 20 years, insecticides applied to U.S. agricultural landscapes have become significantly more toxic — over 120-fold in some mid-western states — to honey bees when ingested, according to a team of researchers, who identified rising neonicotinoid seed treatments in corn and soy as the primary driver of this change. The study is … More Insecticides are becoming more toxic to honey bees.
Results point to a need for increased research, extension, and best management practices. Beekeepers across the United States lost 40.7% of their honey bee colonies from April 2018 to April 2019, according to preliminary results of the latest annual nationwide survey conducted by the University of Maryland-led nonprofit Bee Informed Partnership. Honey bees pollinate $15 billion … More U.S. beekeepers lost over 40 percent of colonies last year, highest winter losses ever recorded.
Wild bees in Europe are in trouble — more than 50 percent of local species are now classified as endangered. Recent findings indicate that, in farming areas, species that emerge in late summer are most acutely threatened. The pollination services provided by wild bees are indispensable, not only for ecological but also for eminently economic … More Insects in decline: On farmland, latecomers lose out.
Adjuvants not as benign as previously thought A new article reveals that adjuvants, chemicals commonly added to pesticides, amplify toxicity affecting mortality rates, flight intensity, colony intensity, and pupae development in honey bees. Adjuvants are chemicals that are commonly added to plant protection products, such as pesticides, to help them spread, adhere to targets, disperse … More Pesticides deliver a one-two punch to honey bees.
