Beekeepers will also find detailed information and downloads about bee diseases in the beekeeping section of the Central Science Laboratory (CSL). Please use the link on the right - note that this link will take you OUT of the SBA Web Site.
The Quick Links at the top right of this page will guide you to a selection of download documents and other web sites that you may find helpful in relation to bee health.
Please direct all enquiries regarding bee health and disease to the Bee Health Convener. You will find contact details for the Bee Health Convener on the Executive page in the 'About' section of the main menu.
There has been much published, both in the national press, on radio and TV, and in scientific journals, about the effect of pesticides on bees. Perhaps the most worrying to beekeepers has been the use of the systemic insecticides known as the neonicotinoids, so called as they are new synthesised compounds similar to the natural but exceedingly potent chemical, nicotine.
Reaction to these, as to all pesticides, has ranged from the emotional, where people throw up their hands in horror and say they must be bad and should be banned immediately, to the logical, that looks carefully at the evidence and the relevance of the published research to colonies of bees in nature, as most of the research is done under laboratory conditions on small samples of bees. It is also important to ask what would be the result of banning neonicotinoids, as other pesticides, possibly more harmful, would replace them.
DEFRA is to be congratulated on preparing a review of the published papers that provides an unbiased opinion on their relevance to beekeepers. This can be accessed at http://www.defra.gov.uk/publications/2012/09/18/pb13818-pesticides-bees/.
This is a very important document, and is recommended reading for all beekeepers.

Apimondia Bee Health Symposium in Dublin had as its theme “From Challenges to Solutions”, and concentrated on Nosema, Varroa, and American Foulbrood (AFB). The Bee Health Convener attended this meeting on behalf of the SBA. His report can be downloaded from the quick links section at the top of the page.
Links to the external sites describing this research are on the home page. The background to this research is quite complex, and the SBA Bee Health Convener has provided the following additional information that those interested in this research may find useful:
What is RNAi?
Genes are made up of deoxyribonucleic acid, or DNA, and a gene consists of a strand of DNA with a sequence of nucleotides, the 'genetic code'.
The gene is a short part of the long DNA molecule (corresponding to the chromosome), and is copied to a ribonucleic acid (RNA) molecule, usually the length of the gene.
These RNA strands then move to the ribosomes, which are the power houses that make the proteins that the gene codes for. As they carry the information from the gene to the ribosomes, this RNA is called messenger RNA (mRNA).
RNAi, or RNA interference, is a technique whereby short strands of RNA are identified that will bind to the mRNA. The effect can be either the degradation of the RNA or, in some cases, to prevent it being formed.
The aim is to control a pest by sequencing a gene, that is essential to the survival of the pest, and identify suitable short RNA strands that will bind to the mRNA and prevent the gene functioning normally, leading to death of the cells and thus of the organism.
