Image of the Week: Varroa Parasitic Mite

argylesock says… Varroa mites are bad news for bees. This is the third of three articles about pollinators, from the Wellcome Trust blog, which I’m passing on today.

B0009404 Varroa destructor, honey bee mite, SEM

This week’s image is of the little mite that might cause the end of food production as we know it. The varroa parasitic mite attacks the honey bee populations needed to pollinate a range of valuable crops including sunflowers, almonds and tomatoes. After attaching itself to the underside of the bee, the mite sucks the hemolymph, a substance that surrounds all the bees’s cells.

It is only possible to see this varroa mite so clearly because the image was created using a scanning electron microscope. Verroa mites are actually only 1.5mm by 1mm making them almost impossible to see on a live adult bee. In reality this mite would also be a red brown colour providing camouflage against the surface of its victim. All images created with a scanning electron microscope are originally colourless, and in this image the purple and green colouring was added later to help us see…

About argylesock

I wrote a PhD about veterinary parasitology so that's the starting point for this blog. But I'm now branching out into other areas of biology and into popular science writing. I'll write here about science that happens in landscapes, particularly farmland, and about science involving interspecific interactions. Datasets and statistics get my attention. Exactly where this blog will lead? That's a journey that I'm on and I hope you'll come with me.
