Varroa Resistance

7 Hives at the end of the season

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.

Anticipating a balancing of the host-parasite relationship

Parasites rely on another organism for aspects of their feeding and/or reproduction. Whilst parasitism is a complex subject, the relationship between Western Honey Bees and Varroa mites is relatively simple. The mites live entirely with and on the bees. Food, reproduction and transport is all provided by bees. In this case, if the host dies so does the parasite.

Winter Losses: 5-NIL

Colonies can fail over winter. Surveys suggest that about 10% fail in a good year; more in a bad one. At the moment, none of my colonies have failed. I'm happy.

It's too early to be certain that all will survive into summer. Each colony will strike a balance between brood production and foraging. If they make too much brood when the forage is poor, they may starve.

Failure can happen because of disease, starvation or an external event. There are lots of diseases and lots of events. There is only one cause of starvation.
