News — social bees

Each month our Bee Informed Blog highlights current news, science, and research related to solitary bee conservation, food insecurity, and sustainability. 1. Native Bees Climb Social Ladder (County News) A native bee which nests in tree-fern fronds is helping scientists understand how life developed to be social and altruistic — and how bees evolved to purposefully hatch sterile young, a fact which defies Darwin’s natural selection theory. The Australian bee Amphylaeus morosus only recently made the jump from being a solitary species to a social one — which made them a perfect, and rare, animal to put under the metaphorical microscope.

Messing with the microbes within their hive-stored pollen hurts bumblebees Of the 20,000+ bee species on Earth, only about a dozen are used by farmers in commercial agriculture, and these crucial populations of managed bees have been declining at an alarming rate. Several factors, including increased use of pesticides, habitat fragmentation, emerging diseases, and reduced genetic diversity may be responsible for such bee losses. In response to this pollinator crisis, recent conservation efforts have led to stricter regulations on insecticide use. However, other agrochemicals such as herbicides and fungicides that do not directly target insects (such as bees) continue to...
