A vaccine can save bin from extinction

Finnish researchers may have discovered the first vaccine in the world to protect bins and avoid reducing the population of these insects. Its extinction can cause a global food crisis.

Bina contribute to pollination of 90% of the most important crops in the world. But in recent years these insects have been decimated by the "syndrome of colony collapse of the bin". The reason for their disappearance can be mites, pesticides, viruses or fungi, and even a mixture of several factors.

According to the UN (UN), over 40% of invertebrate pollinators, especially bees and butterflies, They are threatened with extinction.

According to researchers, its extinction would generate an increase in food prices.

The queen bee should get the vaccine

The vaccine is developed in bin resistance needed to fight microbial diseases serious, potentially lethal to pollinator communities.

before It was thought 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 an insect and immunologist specializes in the fact that butterflies feed certain bacteria They transferred their immunity to their youngsters.

Researchers Freitak and Heli Salmela, who worked with bees and proteins they created a vaccine against "American foul bread", the most widespread and destructive of bieb's bacterial diseases.

The treatment would be administered to the queen of bees with the help of a sugar, just as children receive polio vaccine. In this way, the queen bee transmits immunity to the rest of the colony.

The team tries to make the vaccine available on the market, but There are many regulatory barriers so it would take four to five years to get to the market.

According to a UN study published in 2016, corresponding to EUR 507 million of farmed food Each year, they depend directly on pollinators. The amount of food produced as a result of pollinators has increased by 300% over the past 50 years.

With the reduction of pollinators, some farmers has turned to behead or manual pollination, as is the case with fruit trees in some regions of China.
