Border Bees Diary

Diary of a Beekeeper in the Scottish Borders

Beekeeping in the Scottish Borders

I have kept bees for eight years now – so I am no longer ‘a beginner’ – but many local beekeepers have forty years or more experience, so I am still a long way from being an ‘expert’.  I keep the local ‘native’ bee – i,e, British Black bees – Apis Mellifera Mellifera – rather than using imported Italian, Carniolan (Slovenian) bees.

My bees went into the winter of 2007 with five hives – all in good heart and all with first-year-queens (British blacks – or ‘local stock’. The bees were treated for varroa with Apistan strips in September and after Christmas I dosed them with Oxalic Acid – to guard against varroa gaining chemical resistance. I also tacked heavy duty plastic ‘skirts’ around the hives to shed the rain and wind – using builders damp-proof-membrane – so I thought everything had been taken care of.

When I last peeked into the hives – after Christmas – there were healthy populations of bees in all five hives and plenty of winter stores to see them through the cold months. When I revisited the hives in April I was shocked to discover that one of the hives was dead and another two were queenless – with only a small population of bees surviving.

CAUSES?

The main possible causes noted by the experts seem to be:

1. Varroa parasites and viruses

2. Nosema – dysentery

3. Prolonged cold

4. Accumulation of pesticides in stored food supplies

The general picture that is emerging throughout the UK is that there have been very heavy losses in some areas – lighter losses in others. East Lothian BKA conducted a survey which revealed 10% losses on average. Morayshire BKA reported losses in the 40-50% zone and in one case 12 out of 12 hives were lost.

My own hives are all Open Mesh Floors; all were treated for Varroa (Apistan) in September and seemed in vigorous good health. They were treated with oxalic acid using 3% solution and no more than 5 mls of solution per seam of bees – in early January. The three dead or severely depleted hives were discovered in mid April and I have been nursing my two remaining queenright colonies in the hope of breeding new queens at the end of May.

I took this photo of my best remaining queen on May 10th. Did not see the varroa mites through the veil while inspecting the hive, but did notice them on the enlarged photo today. Very depressing.

    Hi

    There is a deal going down in the craft a t present – what with Patersons’ investigations on queen failure: either to mate, or even survive the pre emerging stage in the cell. Even queen which appear to have mated produce colonies which do not thrive and eventually crash. The systemic pesticide issue, especially the imidacloprid ‘family’ is now high on the agenda. However there is a situation that up till now has been neglected and it is not high tech but basic nuts and bolts stuff!
    Consider the beekeeper who moderately successful at producing quees, despite Paterson’s findings, but who at the end of the active season has a dilemma – he has more stocks than he can overwinter successfully
    bearing in mind that it is only sensible to overwinter the number of colonies which the beekeeper can feed well. If beekeepers had access to economically priced sugar via perhaps a voucher scheme more colonies could be overwintered and thus at a stroke by having increased colony numbers overwintering the losses however high would hopefully overtime produce more surviving colonies year on year. The key is economically priced sugar which would encourage beekeepers to inccrease their colony numbers. A concerted effort collectively by UK beekeepers might just get a result.

    Afternoon Graham
    Picked up your site from the BBKA forum … good work!
    May I suggest you get your links to open up in a new page by inserting … target=”_blank” into your html … ie
