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.
Bees living in suburban habitats are still being exposed to significant levels of pesticides despite the EU ban on the use of neonicotinoid pesticides on flowering crops, new research from University of Sussex scientists shows. While the introduction of new EU restrictions on the use of neonicotinoid chemicals five years ago has reduced exposure of … More Study shows EU pesticide ban failing to protect suburban bees.
Pesticide regulations designed to protect honeybees fail to account for potential health threats posed by agrochemicals to the full diversity of bee species that are even more important pollinators of food crops and other plants, say three new international papers co-authored by University of Guelph biologists. As the global human population grows, and as pollinators … More Stronger pesticide regulations likely needed to protect all bee species, say studies.
Biologists at the University of California San Diego have demonstrated for the first time that a widely used pesticide can significantly impair the ability of otherwise healthy honey bees to fly, raising concerns about how pesticides affect their capacity to pollinate and the long-term effects on the health of honey bee colonies. Previous research has … More Common pesticide damages honey bees’ ability to fly
Scientists from the University of Würzburg have investigated the impact of a new pesticide on the honeybee. In high doses, it has a negative impact on the insects’ taste and cognition ability. In February 2018, the European Food Safety Authority (EFSA) confirmed that the pesticide group of neonicotinoids is harmful to bees. A novel pesticide … More Pesticides give bees a hard time
Pesticide exposure can dramatically impact bees’ social behaviors, study shows, For bees, being social is everything. Whether it’s foraging for food, caring for the young, using their bodies to generate heat or to fan the nest, or building and repairing nests, a bee colony does just about everything as a single unit. While recent studies … More Bees on the brink

Coles and Woolworths are abandoning an insecticide product which contains a controversial ingredient that has been linked to harming bee populations essential for pollination, The New Daily can reveal. More than 30,000 Australians have signed a petition, launched by global consumer group SumOfUs, calling on Australian retailers to stop selling insecticides containing neonicotinoids, including Yates Confidor which has been … More Woolworths and Coles cave in to pressure to abandon product accused of killing bees
Source: National Centre for Biological SciencesSummary:Although at least 75 percent of our crop species depend on animal pollinators, little is known about their flower preferences. As global insect populations decline, it is of utmost importance for us to understand what factors attract wild pollinators to flowers, and how these preferences differ in the face of … More Laws of attraction: Pollinators use multiple cues to identify flowers across continents
Seemingly indestructible Varroa mites have decimated honeybee populations and are a primary cause of colony collapse disorder, or CCD. Scientists have found genetic holes in the pests’ armor that could potentially reduce or eliminate the marauding invaders. The team’s results have identified four genes critical for survival and two that directly affect reproduction. Michigan State … More Varroa mites — bees’ archenemies — have genetic holes in their armor
