Solar Eclipse

Today, there is a total eclipse of the sun at various times right across the USA from Oregon to South Carolina.

How will bees react? Please tell us of your observations. Email info@vita-europe.com

Here are some reports of earlier eclipses that we reported on in 2015.

Vita’s first Basingstoke allotment harvest

Despite opening its trials apiary in a Basingstoke allotment late this season, Vita has harvested a crop. Well, actually it’s two Basingstoke beekeepers who have done the harvesting.

Derek Western, one of the Basingstoke beekeepers, said: “I wasn’t expecting any harvest this year, but we were surprised by one colony. Next year should see a lot more as all colonies will have had a chance to build up and forage for a full season.

“Interestingly, there’s a marked difference between honey from the Vita Apiary and that harvested from my own apiary on a nearby allotment, even though they are only one mile apart. The Vita apiary honey is  light and floral honey with an aftertaste of lime.”

Paulo Mielgo, Vita’s apiarist is sharing the jars amongst the team.

Pollen-rich diets help combat varroa

We have known that honey bees use plant resins with antibiotic properties to control pathogens in the colony, but a multi-national team of researchers has just shown that pollen-rich foods help too.

In investigating this “social immunity”, they tested to see if pollen is beneficial for honey bees infested with the parasitic mite Varroa destructor which is associated with deformed wing virus (DMV).

First, they studied the effects of pollen on the survival of infested bees in the laboratory and in the field. They observed that a pollen-rich diet can compensate the negative effects of mites. They went on to identify the beneficial pollen compounds.

Under lab conditions, pollen did not have much effect on bees without varroa, but it did lengthen the lives of those infested by the mite. In the field, although the sample size was small, the effect was more dramatic with all of the control colonies dying out while two pollen-fed colonies survived.

The researchers think that it is the lipidic compounds of pollen that have a positive effect – but they don’t rule out other compounds. They even think that bees may be deliberately selective in their foraging to get the right balance of macronutrients.

Asian hornet predictions in the UK

Asian Hornet

With the ability to spread at the rate of 70-80 km per year, what are the prospects if the Asian hornet (Vespa velutina) takes hold in the UK?

The first Asian hornet nest was discovered and destroyed in the UK last year, so researchers have tried to predict its spread in Britain if it can establish itself. Their work is inevitably hypothetical, but it has been based on the eight-year experience of events since the arrival of the hornet in France.

Prevention of the spread of the Asia hornet is a pressing concern because in France its diet consists about 50% of Apis mellifera, with other valuable pollinators contributing to the rest.

The researchers set about creating a mathematical model to try to predict the track of the potential invasion. They made some assumptions: the average distance for a queen to fly to set up a new nest is 28 km, but fortunately it is not expected to do well as it travels north and they have tentatively expected it not to establish itself at all in northern England. They have even managed to factor in eradication attempts.

After 10 years, the invasion could be widespread with more than 50,000 nests with as many as five nests in each km2 in certain areas. After 2o years, an area’s carrying capacity is expected to have been reached.

Uncontrolled expansion will be disastrous say the researchers, so detection and eradication is vital. They think that limited local searching would result in a a finite – and often short – time until control efforts fail. New incursions are likely to increase over time as the hornet becomes further established in mainland Europe.

In France, only 48% of nests have been detected and this is not enough to control an invasion, say the researchers. Nonetheless, valuable lessons can be learned from the French experience.

The year 2017 is thought to be critical to the immediate future – if more nests are found, the prospects are not good, but if none are discovered this will be reassuring giving the possibility that the south of England is not a conducive environment for the hornet.

Meantime, Vita suggests putting its Apishield Asian hornet traps in place to monitor – and to protect.
