Researchers could have detected vaccines that protect bin technology


Scientists believe they have discovered in Finland's first vaccine in the world to protect bin and avoids the collapse of the population of these insects, which can cause a global food crisis.

Bina actually contributes to pollination of 90% of the most important crops in the world

But in recent years these valuable insects have been decimated by "Colony Collapse Syndrome", a mysterious evil. It is accused of causing myths, pesticides, viruses or fungi, and even a mixture of several of these factors.

According to the UN, more than 40% of invertebrate pollinators, especially bees and butterflies threatened with extinction.

Its strong decline can, according to researchers, create one rising food prices, and the risk of difficulties.

Medical advance

The vaccine, product of the work of a team of University of Helsinki, provides bin with the necessary resistance to combat serious microbial diseases, potentially fatal to pollinator groups.

"If we can even save a small amount of bees with this invention, I think we would do our good deed, save the world a little," he said. Dalial Freitak, researcher who leads the project.

"There would even be a large increase of 2 to 3% of the population of the bipolar", Confirms to AFP.

It was thought earlier that it was impossible to vaccinate insects because they do not have antibodies, one of the most important mechanisms that humans and other animals use to fight disease.

But in 2014, Freitak, an insect and immunologist, realized that butterflies fed with some bacteria transmitted their immunity to their offspring.

Freitak and Heli Salmela, who worked with bees and proteins, created a vaccine against American foul bread, the most widespread and destructive of bacterial diseases at the bee.

The treatment is administered to the queen of the queen using a sugar, just as the children receive the vaccine against polio. The queen then sends her immunity to her offspring.

The team tries to make the vaccine available on the market, but "There are many legal obstacles" so waiting "four to five years to come to the market is an optimistic estimate", according to Freitak.

Different reasons

Researchers believe that diseases they are just one of the many reasons of the loss of pollinators. It is also intensive agriculture, which reduces the diversity of insecticides and pesticides.

However, the Freitak team believes that the protection of biblical diseases against diseases will make them stronger and therefore better equipped to resist other threats.

the European Union and Canada They voted for the ban on neonicotinoids, which are considered very harmful for the reproduction of bees.

According to a United Nations study published in 2016, the equivalent of 507,000 million euros corresponds to food grown annually on pollinators. The amount of food produced depends on pollinators increased by 300% over the past 50 years.

With the reduction of pollinators, some farmers have turned to beard or manual pollination, as in the case of fruit trees in some regions of China.

In Helsinki, the project is supported by external funding, but the team intends to continue its research in University of Graz in Austria, the famous zoologist Karl von Frisch. His discoveries about the dance of bin as a communication method and its application in human language deserve him the Nobel Prize in Medicine in 1973.
