Non-contact exposure to dinotefuran disrupts honey bee homing by altering MagR and Cry2 gene expression

Non-contact exposure to dinotefuran disrupts honey bee homing by altering MagR and Cry2 gene expression Dinotefuran is known to negatively affect honeybee ( Apis mellifera ) behavior, but the underlying mechanism remains unclear. The magnetoreceptor ( MagR , which responds to magnetic fields) and cryptochrome ( Cry2 , which is sensitive to light) genes are considered to play important roles in honey bees’ homing and localization behaviors. Our study found that dinotefuran, even without direct contact, can act like a magnet, significantly altering MagR expression in honeybees. This non-contact exposure reduced the bees’ homing rate. In further experiments, we exposed foragers to light and magnetic fields, the MagR gene responded to magnetic fields only in the presence of light, with Cry 2 playing a key switching role in the magnetic field receptor mechanism ( MagR–Cry2 ). Yeast two-hybrid and BiFc assays confirmed an interactio...

“Global honey crisis”: Testing technology and local sourcing soars amid fraud and tampering concerns

“Global honey crisis”: Testing technology and local sourcing soars amid fraud and tampering concerns The World Beekeeping Awards will not grant a prize for honey next year due to the “inability” to thoroughly test honey for adulteration. The announcement comes amid the rise of honey fraud in the EU, where a 2023 investigation found that 46% of 147 honey samples tested were likely contaminated with low-cost plant syrups. Apimondia, the International Federation of Beekeepers’ Associations, organizes the event at its Congress, whose 49th edition will be held in Copenhagen, Denmark, in September 2025. The conference brings together beekeepers, scientists and other stakeholders. “We will celebrate honey in many ways at the Congress, but honey will no longer be a category, and thus, there will be no honey judging in the World Beekeeping Awards. The lessons learned from Canada 2019 and Chile 2023 were that adequate testing was impossible if we are to award winning honey at the Con...

Start the New Year Humming Like a Bee

Start the New Year Humming Like a Bee There are lots of opportunities to be as busy as a bee during these winter holidays. As we hustle toward the dawn of the New Year, it can be hard to notice that the natural world is actually suggesting something different for us right now. We’re past the solstice, but the winter still stretches ahead, the days are still short and the nights long. We’re being invited into a quieter, more inner-focused time. The ancient yogis were all about this inner focus. In India, for example, the Upanishads, the Sanskrit writings that accompanied the development of Hinduism — and alongside it, yoga — beginning around 800 B.C.E., went deeper than earlier texts had into philosophy and questions of being. With the goals of increased inner awareness and higher consciousness, yoga was at that time not yet as focused on the body or on asanas, as it now can tend to be. But the yogis did develop many practices to try to open the way to those goals. They discovered...

The largest “killer hornets” in the world were exterminated in the US

The largest “killer hornets” in the world were exterminated in the US The US informed that it had exterminated the worldʼs largest hornets, nicknamed "killer hornets" — they are capable of occupying a hive of honey bees in just 90 minutes, decapitating all its inhabitants and feeding their offspring to their own. This was reported by the Department of Agriculture in Washington. The hornets, which can reach five centimeters in length, were previously called Asian giant hornets, but in 2019 they were also spotted in Washington state near the Canadian border. In China, these insects killed 42 people and seriously injured 1,675. A dead northern giant hornet (below) next to a native bald hornet. According to experts, the hornets could have entered North America in plant pots or shipping containers. The hornet can sting through most beekeeper suits because it produces nearly seven times more venom than a honeybee and stings multiple times. Thatʼs why the Washington Departme...
