According to United Nations data, more than 40% of invertebrates belt, especially bees and butterflies, are threatened to disappear. Finnish scientists could help tackle this situation through the first vaccine in the world to protect bees and prevent the fall of these insects, which could cause a global food crisis .
The bees contribute to pollination of 90% of the main crops in the world. But in recent years, these valuable insects have been disregarded by the "collapse collapse syndrome", it is a mysterious evil. I am accused of causing granite, pesticides, viruses or mushrooms, and even a mixture of many of these factors.
Its vertiginous decline, according to scientists, could increase the rise in food prices, and risk of hardship.
The vaccine, a team work product from the University of Helsinki, provides the necessary resistance to bees to tackle severe, potentially deadly macrobial diseases to communities that beillio.
"If we can save even a small part of the bees with this device, I believe we would do our good deeds, saving the world a bit" says Career Freitak, a projector researcher and project.
"It would even be a huge increase of 2 to 3% of the population of bees" confirms the AFP.
It was believed that in the past it is impossible to vaccinate insects, because they do not have antibodies, one of the main mechanisms that other people and animals use to fight diseases.
But in 2014, Freitak, an insect specialist and immunology, realized that butterflies fed with some bacteria transfer their immunity to a fluid.
Freitak and Heli Salmela, who were working on bees and proteins, created a vaccine against American foulbrook, the most beekeeper and behavioral bacterial diseases of the bees.
How do you "vaccinate" bees?
The treatment is administered to the queen of bees by sugar, in the same way that the children get the vaccine against polio.
Then, the queen transfers her immunity to older.
The team is trying to make the vaccine available in the market, but "there are many regulatory barriers" so it is expected "four to five years to reach the market is an optimistic estimate," according to Freitak
Scientists believe that many of the causes of losing blinkers are only diseases. There is also intensive agriculture, which reduces the variety of insect and pesticide feeding.
But the Freitak team believes that the protection of bee populations against diseases will make them stronger, and therefore prefer to resist other threats.
The European Union and Canada voted for the prohibition of prohibition of neonicotinoids, which were considered to be very harmful for the reproduction of bees.
According to the UN study published in 2016, the amount equal to 507,000 million euros of food grown every year depends directly on blinkers. The amount of food produced that depends on blinkers has increased by 300% over the last 50 years.
With the decline of bumblebees, some farmers have turned to honey or bee hire, 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 with research at the University of Graz in Austria, the famous actor, Karl von Frisch. He won his discoveries about bee dancing as a means of communication and applied to the human language of a Nobel Prize in Medicine in 1973.
