What’s making the bees all sick and killing them, too?

Found in Biology.


The pesticides they spray on plants is toxic and poisons them when they go to drink the nectar.

There are many things attributed to colony collapse disorder. Competition with other invasive species, infestation of mites, toxins from pesticides, and more many of which are still being researched.

Best evidence at the moment is that there are wide-spread infections of a disease carrying parasite, [varroa destructor](https://en.wikipedia.org/wiki/Varroa_destructor). A family of modern insecticides, the neonicotinoids, makes the bees less resistant to the mites.

While the number of bee colonies that die annually has increased, reports of their disappearance are [greatly exaggerated](https://usda.library.cornell.edu/concern/publications/rn301137d?locale=en).

In Denmark we had a problem last year with us having warm temperatures in January. So the bees thought it was summer time and they woke up and started working. When it a week later went freezing and snowing, they tried going back to their long sleep again, and that was what our big problem was, because it killed them.
This year we have a problem with our potatoes because it went freezing in April..
