Flying threat: Why are killer

Bees in UK

Wild honey bee colonyBy Zoe Gough Reporter, BBC Nature Wild colonies would be surviving on their own in remote areas or in cavities

New analysis implies there may be no crazy honey bees located in England or Wales, but how much does their particular disappearance matter?

Inspite of the current international issue at the wellness of managed honey bee shares, the presence - and potential advantages - of wild local honey bees is usually over looked.

Wild colonies is associated with UNITED KINGDOM's local honey-bee subspecies Apis mellifera mellifera, also referred to as the European dark bee, enduring by themselves in remote places or in a range of cavities.

It has been recommended that condition wiped them in the early twentieth Century, however across most parts of the UK there continue to be anecdotal sightings of colonies flourishing without person intervention.

Dr Catherine Thompson obtaining feral coloniesAnd the reality that unmanaged bees haven't been eradicated is of interest to those attempting to protect honey bees. But no empirical research reports have already been performed to simplify the situation.

Dr Catherine Thompson, from University of Leeds, attempt to explore the perseverance, hereditary variety and disease burden of crazy honey bees in The united kingdomt and Wales.

She identified three remote places at the very least 6.2 miles (10 km) from any known apiaries (Tywi Forest in Wales, Ennerdale woodland, Cumbria additionally the Kielder woodland in Northumberland) and sampled all of them making use of bee traps, lures and observations. No crazy honey bees were discovered.

Mcdougal figured you can find not likely become any big, remote colonies of crazy honey bees remaining in The united kingdomt and Wales and, thus, she turned her attention to feral honey bees - colonies residing in the crazy which can be thought to have escaped from managed shares.

Genetic evaluating between your handled and feral colonies showed close similarities (2.5% distinction) which she recommended meant that feral colonies were likely to be swarms from handled colonies.

The managed colonies were further separated into the ones that had been addressed the varroa mite and people that were not.

Varroa mites (Varroa destructor) joined the united states in 1992, and generally are regarded as the most destructive parasite in honey bees and an important cause of winter months colony loss.

Dr Thompson unearthed that the feral and non-treated managed colonies had a dramatically advanced of Deformed Wing Virus (DWV), which can be transmitted to bees because of the varroa mite, than the managed colonies that were treated.

By going back to the feral sites every spring and autumn for the following 36 months she found those colonies with high degrees of condition were unlikely to endure.

The outcomes of Dr Thompson's pathogen burden study are due to be published into the record PLoS One.

"This study is essential given that it shows bee keepers that they are ultimately in charge of honey bees", Dr Thompson told BBC Nature. "If they stopped looking after their particular bees it is likely there would be no bees left.

"It is beekeepers' obligation to keep healthy and top quality bees which means that continue with a programme of research into honey-bee health, honey bee genetics and also the health regarding the landscape by which we keep them."

Tim Lovett from the British Beekeepers Association said the study reiterated his organisation's founding maxims.
