Inbreeding and disease are factors in decline of yellow-banded bumblebee

Clues show that their immune genes are under selection, pointing to disease as a likely cause of yellow-banded bumblebee. By sequencing the genome of the yellow-banded bumblebee, York University researchers have found that inbreeding and disease are likely culprits in their rapid decline in North America. This is believed to be the first time the genome … More Inbreeding and disease are factors in decline of yellow-banded bumblebee

Neonics put bumblebees at risk of extinction by hindering colony formation, study reveals

Exposure to thiamethoxam reduces the chances of a bumblebee queen starting a new colony by more than a quarter. Bumblebees are less able to start colonies when exposed to a common neonicotinoid pesticide, according to a new University of Guelph study. Prof. Nigel Raine has discovered that exposure to thiamethoxam reduces the chances of a … More Neonics put bumblebees at risk of extinction by hindering colony formation, study reveals

WHAT ARE NEONICOTINOIDS? TRUMP ADMINISTRATION ROLLS BACK BAN ON SYNTHETIC CHEMICAL PESTICIDES

A memo from the US Fish and Wildlife Service announced on Thursday that the Trump administration rolled back an Obama-era ban on neonicotinoids, a group of synthetic chemical pesticides that are linked to the decline of wild bee populations around the world. This ends a policy that had prohibited farmers on refugees from planting genetically engineered crops. The chemicals have been … More WHAT ARE NEONICOTINOIDS? TRUMP ADMINISTRATION ROLLS BACK BAN ON SYNTHETIC CHEMICAL PESTICIDES

Forty percent of invertebrate pollinators like bees and butterflies are facing extinction, according to a UN report released February 26

REUTERS/PETER BADERBY CHRISTINA PROCOPIOU   Pollinators are under threat—and that means that one in three bites of food that we eat is at risk. Additionally, this threat places the almost 90 percent of flowering plants needing pollination across the world on shaky ground, potentially endangering the wildlife that depend on them for food. According to a report sponsored by … More Forty percent of invertebrate pollinators like bees and butterflies are facing extinction, according to a UN report released February 26

Beetle adapts chemical mimicry to parasitize different bee species

A beetle that tricks bees into carrying it into their nests where it can live off their pollen, nectar and eggs adapts its deceptions to local hosts, according to research by Leslie Saul-Gershenz, a graduate student in entomology at UC Davis. Aggregations of the larvae of Meloe franciscanus beetles lure male digger bees (genus Habropoda) with … More Beetle adapts chemical mimicry to parasitize different bee species

Inbreeding and disease are factors in decline of yellow-banded bumblebee

Clues show that their immune genes are under selection. By sequencing the genome of the yellow-banded bumblebee, York University researchers have found that inbreeding and disease are likely culprits in their decline in North America. “The yellow-banded bumblebee has been declining throughout much of its range in North America, but we don’t know why,” says … More Inbreeding and disease are factors in decline of yellow-banded bumblebee
