Bee deaths: EU to ban neonicotinoid pesticides

From BBC News

A vote in the EU has paved the way for the European Commission to restrict the use of pesticides linked to bee deaths in scientific studies.

Neonicotinoid chemicals in pesticides are believed to harm bees and the European Commission says they should be restricted to crops not attractive to bees and other pollinators.  But many farmers and crop experts argue that there is insufficient data.

Fifteen countries voted in favour of a ban - not enough to form a qualified majority. According to EU rules the Commission will now impose a two-year restriction on neonicotinoids - and the UK cannot opt out.

The UK did not support a ban - it argues that the science behind the proposal is inconclusive. It was among eight countries that voted against, while four abstained.

The Commission says it wants the moratorium to begin no later than 1 July this year.

Starvation Risk update

Following our post about bee starvation and what looks to be another few weeks of terrible weather, it is advisable to start thinking about feeding your colonies some form of pollen substitute. By now the winter bees will have started to die off and the production of brood to replace these loses are important. However, without suitable protein and nectar, the development of brood will be damaged and in some instances may not happen at all.

It is always better to source a pollen substitute from a commercial/ equipment supplier because the consistency of the product will always be assured and they are specifically designed to help boost a colony. However, if you cannot source a pollen substitute it can be made up by mixing 3 parts (by weight) soybean flour, 1 part dried brewer’s yeast (Saccharomyces cerevisiae) and 1 part dry skimmed milk. Prepare a solution of 2 parts by volume of sugar to 1 part hot water.

Let the solution cool and mix one litre of this solution with 400 grams of the substitute. Form it into a cake and wrap in grease proof paper, if necessary they can be stored in a freezer. When using cut a small hole in the paper and place the package hole side down on the top bars over the cluster and preferably over open brood. The bees will tear the paper away and feed on the cake. It is important that the cake remains moist or bees will ignore it, so maintain the paper cover over the top or wrap it in several layers of cling film and pierce a hole big enough for the bees to get in and feed on it.

The amount fed is variable depending on the strength of the colony and external conditions. A small colony on three frames may only need 50 grams a week whilst a very strong colony may require more.
Maintain feeding substitutes until there is an adequate natural pollen crop as it may be detrimental to the colonies development to stop beforehand. This is because brood food production may be affected leading to the starvation of larvae.

Remember homemade pollen substitutes can be very variable in nutritional value due to the different ingredient brands. Generally it is better to obtain a commercial honeybee pollen substitute as the quality is assured.

Pollen substitutes must not be used if the colony is starving because it is more important to get feed into the colony rather than protein. One your hives have suitable food stores, you may then place a pollen pate on the top bars, if there isn’t already a natural source coming in.

Finally it is also worth noting that in some parts of the country, bees are still reluctant to take liquid syrup but will use invert syrups such as ambrosia. If you find that your bees are taking neither then stick to fondant until the weather warms up.
