A number of people have mentioned varroa mites and the problems they cause for domestic and wild bee populations. For those interested mycologist Paul Stamets has been trialing the addition of polypore extract to bee food (water / sugar water) to boost their immune system. Results on smaller sample set (~100 hives) was near total eradication of the mites (I think broken wing disorder was diminished too). Next trial is on sample size of 10k+ hives.

Since domestic and wild bees comingle this should reduce transmission from domestic to wild bee populations, and hopefully give wild bees a chance to recover.

For those interested you’ll be able to find Stamets talking about this on YouTube in his talk “Into The Mycoverse”, and elsewhere, I’m sure.
