Bee body mass, pathogens and climate influence heat tolerance

How well bees tolerate temperature extremes could determine their ability to persist in a changing climate. But heat tolerance varies between and within populations, so a research team led by Penn State entomologists examined bee physical traits — such as sex differences in body mass — to understand how these traits interact with environmental conditions, pathogens and other factors.

Scientists evolve a fungus to battle deadly honey bee parasite

The biggest scourge to bees is tiny—a mite the size of a pinhead that feeds on them and spreads deadly viruses. Getting rid of the parasite, Varroa destructor, is tough: Chemicals can kill it, but the mite has started to evolve resistance to the usual pesticides; moreover, these and other treatments can harm the bees themselves. Now, researchers have toughened up a mite-killing fungus so it can slay the bee slayers inside a hot beehive. If the new strain passes further tests, it could help honey bees around the world avoid a gruesome fate, and reduce the use of chemical pesticides.
