Une étude révèle que les abeilles deviennent agressives sans pollen

Une nouvelle étude de terrain montre que les abeilles privées de pollen deviennent plus agressives et présentent des signes de stress. Les chercheurs ont simulé une pénurie de pollen sur une période de cinq semaines afin d'examiner les effets sur le comportement et la santé des abeilles.

Les recherches ont été dirigées par Elizabeth Walsh de l'Agricultural Research Service au sein de la Honey Bee Breeding, Genetics, and Physiology Research Unit à Baton Rouge, en Louisiane. Des scientifiques de la Pollinator Health in Southern Crop Ecosystem Research Unit à Stoneville, dans le Mississippi, ont également participé à ces travaux. Ils ont comparé un groupe expérimental d'abeilles ayant reçu une quantité limitée de pollen à un groupe témoin disposant de réserves adéquates.

California hybrid bees resist deadly Varroa mites

21 avril 2026 Rapporté par l'IA

A hybrid population of honeybees in Southern California demonstrates natural resistance to Varroa mites, a major threat to bee colonies. Researchers at UC Riverside found these bees carry 68% fewer mites and require far less chemical treatment. The discovery, detailed in a new study, suggests early-life defenses in larvae may hold the key.

UC Berkeley scientists detect alcohol in floral nectar drunk by bees and hummingbirds

25 mars 2026 Rapporté par l'IA

Researchers at the University of California, Berkeley have found ethanol in the nectar of most plant species examined, meaning pollinators like bees and hummingbirds consume alcohol daily. An Anna's hummingbird drinks an amount equivalent to one human alcoholic beverage per day, yet shows no intoxication. The findings, published March 25 in Royal Society Open Science, suggest evolutionary tolerance to low-level ethanol.
