There are few things that could be worse than finding varroa in your hive, but the small hive beetle (SHB) may come close. This unpleasant squatter, which originated in sub-Saharan Africa spreading to Australia and US, has been sighted uncomfortably close to home in Italy. What is SHB and why don’t we want it?
“It is small, only about 5.7mm in length, black and with tiny clubbed antennae. Each female beetle can lay up to 1,000 eggs, hidden away in crevices in the hive or laid in comb containing pollen or brood. These hatch, after a few days, into tiny larvae which feed on bee eggs and larvae, pollen and honey, tunnelling through the wax in the process…Their faeces get into the honey, causing it to ferment and become frothy and unusable, even for bee feed. There is no webbing, as with the wax moth larvae…but the combs become slimy and the beetles, in addition to weakening a colony and depleting it of brood and/or stores, can become a serious threat to survival.” The Honey Bee Around and About Celia Davis
That makes the wasps bothering our bees seem positively nice! So what’s the chance of SHB causing problems in the UK?
BeeCraft, the magazine of British beekeepers, held a chat about SHB as part of their BeeCraft Live series. The BeeCraft team were joined by University of Florida researcher Jamie Ellis to chat about what impact SHB might have on British beekeepers if it does arrive in the UK.
I was hopeful from this general chit-chat that beekeepers in the US and Australia have learned to live with SHB, and that our cold damp climate might be in our favour for a nasty squatter that doesn’t like long winters. EDIT: However, in the comments below some beekeepers have found SHB may be fairly resilient to the cold, that where it has brought down colonies it can be devastating, and suggest that we do need to be vigilant in ensuring it doesn’t arrive on the UK. I wholeheartedly agree with that!
