7 Hives at the end of the season

Submitted by will on Sun, 10/15/2017 - 20:28

I visited my out-apiary today and examined the removable hive floors for evidence of recent activity.

Three hives (D, F and G) show evidence of recent brood emergence. There were also hundreds of dead mites. Hive D had been especially prolific. There was also crystallised sugar which suggests that old honey is being eaten or cells are being cleaned out.

New comb and high weather in October

It's mid-October. The weather is supposed to be cooling but that's not what we're getting. Storm Ophelia is on its' way, bringing high winds and high temperatures. In Oxford we're forecast to get 40mph winds (fearties! fearties!) and 20C temperatures. The average October temperature is 10.1C (source: /node/191).

The weather must be helping the bees to forage because Hive H shows the tell-tale white wax platelets on the hive floor. These indicatethat they're building new comb.

Mite Crisis in Hive E

Hive E is having a Varroa mite crisis. I checked today and for the previous 2 weeks. Each time I found hundreds of dead Varroa mites.

High mite drop can be a factor in colony collapse. I don't expect them to perform well next season - if they survive through the winter. I expect them to be weakened, and any brood raised in early spring will be heavily infected with Deformed Wing Virus or other diseases symptomatic of Varroosis.
