Fipronil and imidacloprid reduce honeybee mitochondrial activity
Bees have a crucial role in pollination; therefore, it is important to determine the causes of their recent decline. Fipronil and imidacloprid are insecticides used worldwide to eliminate or control insect pests. Because they are broad‐spectrum insecticides, they can also affect honeybees. Many researchers have studied the lethal and sublethal effects of these and other insecticides on ...

Risks of neonicotinoid insecticides to honeybees
The European honeybee, Apis mellifera, is an important pollinator of agricultural crops. Since 2006, when unexpectedly high colony losses were first reported, articles have proliferated in the popular press suggesting a range of possible causes and raising alarm over the general decline of bees. Suggested causes include pesticides, genetically modified crops, habitat fragmentation, and ...

Dancing Bees Waggle the Way to Happier Habitat
Honeybee waggle dancers are helping researchers identify conservation best practices. The question scientists at the University of Sussex in the U.K. had was simple: Where do honeybees find food? But finding a way to answer that simple question seemed not so simple. Tiny radio or GPS trackers have a limited range, and it would take huge amount of work to survey fields on foot. Instead, ...

The newest strategy for saving bees is really, really old
With pollinators in decline around the world, conservationists turn to traditional farmers for answers. In northwestern India, the Himalaya Mountains rise sharply out of pine and cedar forests. The foothills of the Kullu Valley are blanketed with apple trees beginning to bloom. It’s a cool spring morning, and Lihat Ram, a farmer in Nashala village, shows me a small opening in a log hive ...

Bumble bee pollinators in red clover seed production
Bumble bees pollinate red clover (Trifolium pratense L.) but impact on seed production depends on the species, abundance, and synchrony with bloom. The objectives of the current study were to examine pollination by a native bumble bee, Bombus vosnesenskii (Radoszkowski), determine the bumble bee fauna associated with red clover in Oregon, and assess if seed set is limiting. In a cage study, ...

Metal contaminant accumulation in the hive: Consequences for whole colony health and brood production in the honey bee (Apis mellifera L.)
Metal pollution has been increasing rapidly over the past century, and at the same time, the human population has continued to rise and produce contaminants that may negatively impact pollinators. Honey bees (Apis mellifera L.) forage over large areas and can collect contaminants from the environment. The primary objective was to determine whether the metal contaminants cadmium (Cd), copper ...

EPA Releases Preliminary Risk Assessment for Neonicotinoid Insecticide Imidacloprid
On January 6, 2016, the U.S. Environmental Protection Agency (EPA), in collaboration with California’s Department of Pesticide Regulation (DPR) announced the release of a preliminary pollinator risk assessment for the neonicotinoid insecticide, imidacloprid (Preliminary Risk Assessment or Assessment). In its assessment, EPA states that imidacloprid potentially poses a risk to hives when the ...

Fipronil promotes motor and behavioral changes in honey bees (Apis mellifera) and affects the development of colonies exposed to sublethal doses
Bees play a crucial role in pollination and generate honey and other hive products; therefore, their worldwide decline is cause for concern. New broad‐spectrum systemic insecticides like fipronil can harm bees, and their use has been discussed as a potential threat to bees' survival. In the present study, the authors evaluated the in vitro toxicity of fipronil and noted behavioral and motor ...

World Bee Day
The 20th of May marks World Bee Day, aiming to raise awareness about the importance of bees in our ecosystem. Bees are vital to pollinate the food we eat as well as the trees and flowers which are habitats for wildlife, thanks to bees we can enjoy a range of foods from apples to coffee. Approximately 75% of the world’s crops depend, to some degree, on pollinators to provide high yields of good ...

Agroecology can help fix our broken food system. Here’s how.
The various incarnations of the sustainable food movement need a science with which to approach a system as complex as food and farming. This story was co-published with Food Tank, a nonprofit organization focused on building a global community for safe, healthy, nourished eaters. Thumb through U.S. newspapers any day in early 2015, and you could find stories on President Obama’s ...

No impact of DvSnf7 RNA on honey bee (Apis mellifera L.) adults and larvae in dietary feeding tests
The honey bee, Apis mellifera L. is the most important managed pollinator species worldwide and plays a critical role in pollination of a diverse range of economically important crops. Due to this species' importance to agriculture and its historical use as a surrogate species for pollinators to evaluate the potential adverse effects for conventional, biological and microbial pesticides, as ...

Woodland Burial Sites
The Funeralcare Co-operative Plan Bee Wildflower Meadow Creation As part of the ambitious Plan Bee project (which aims to save the plight of honey bees and pollinators across the UK), the Funeralcare Co-operative Woodland Burial Sites have been awarded funding to create bee friendly wildflower corridors. BritishFlora are managing the habitat creation of two wildflower meadows in Dorset of up ...

USGS Study Points To Biofuel Crop Related Land-Use Change Reducing Honey Bee Habitat
On August 29, 2016, the U.S. Geological Survey (USGS) published a study on the result of land-use changes on North and South Dakota commercial honey bee colonies in the journal Proceedings of the National Academy of Sciences. USGS scientists found that grasslands and other landscape features favored by beekeepers were decreasing, with crops that are avoided by beekeepers, such as corn and ...

EPA Registers Long-Term Uses for Sulfoxaflor
On July 12, 2019, the U.S. Environmental Protection Agency (EPA) announced in a Decision Memorandum that it has registered new uses and restored previously registered uses for sulfoxaflor. EPA has approved the use of sulfoxaflor on alfalfa, corn, cacao, grains (millet, oats), pineapple, sorghum, teff, teosinte, tree plantations, and restored the uses on citrus cotton, cucurbits (squash, ...
