Each month our Bee Informed Blog highlights current news, science, and research related to solitary bee conservation, food insecurity, and sustainability. 1. Murder hornets given new common name by entomologists (Associated Press) The invasive hornet found in Washington state that has been referred to as the Asian giant hornet or murder hornet has a new name. Washington state Department of Agriculture officials said Monday that the Entomological Society of America (ESA) has adopted “northern giant hornet” for the species Vespa mandarinia in its Common Names of Insects and Related Organisms List. Continue reading... 2.

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. The...

Each month our Bee Informed Blog highlights current news, science, and research related to solitary bee conservation, food insecurity, and sustainability. 1. The loss of insects is an apocalypse worth worrying about (Vox) Perhaps you don’t think much about the value of dung beetles. But without them crawling around farms, stables, and wild savannas today, the world would be pretty, er, shitty. What about the importance of small, mosquito-like flies called midges? Without them, there’d be no chocolate and likely no ice cream because they pollinate both cacao and the plants that feed dairy cows. “There are lots of tiny little things...

Mason bees are susceptible to many parasites and diseases, increasing over time, especially when the same nest materials are used for multiple seasons. One of the most destructive diseases of cavity-nesting bees is chalkbrood, which is caused by the fungal pathogen Ascosphaera. Several species of Ascosphaera exist, including Ascosphaera torchioi (affects mason bees), A. larvis, and A. aggregata (affects alfalfa leafcutter bees). Chalkbrood disease also affects honey bees, but it is caused yet another species of the fungus—Ascosphaera apis. Adult bees are not affected by chalkbrood, but they contribute to its spread. Adult masons pick up Ascosphaera spores from flowers and transfer them to the pollen ball they create for their...
