Life without bees isn’t life at all. Seriously, have you considered just how empty supermarkets would be if the tiny, bumbling insects went extinct? Since the 1980s, bee populations have diminished dramatically. At least 61 culprits – from viruses to pesticides – have been blamed, but scientists are still groping for answers. One culprit in particular – the mite – is thought to be a major …
Mapping Study Pins Wild Bee Decline on Intensive Farming Practices
A national study suggests that intensive farming is perhaps the greatest danger to wild bee survival. Led by University of Vermont scientist Dr. Insu Koh, the research team is the first to compare the species’ population over time with the location of pollinator-dependent crops. The researchers found that between 2008 and 2013, the abundance of wild bees dropped in almost …
Tiny Parasite May Contribute to Declines in Honey Bee Colonies by Infecting Larvae
Biologists at UC San Diego have discovered that a tiny single-celled parasite may have a greater-than expected impact on honey bee colonies, which have been undergoing mysterious declines worldwide for the past decade. In this week’s issue of the journal PLOS ONE, the scientists report that a microsporidian calledNosema ceranae, which has been known to infect adult Asiatic and European honey bees, …
Inside the Wonderful World of Bee Cognition – Where We’re at Now – Felicity Muth
As I wrote about in my last post, bees are capable of learning which flowers offer good nectar rewards based on floral features such as colour, smell, shape, texture, pattern, temperature and electric charge. They do this through associative learning: learning that a ‘conditioned stimulus’ (for example, the colour yellow) is associated with an ‘unconditioned stimulus’ (nectar). Learning simple associations like …
