How power lines affect the behavior of bees?
Source:
around the world there has been a dramatic reduction in the number of bees
Bees are one of the most beneficial insects on our planet. Basically, they are extremely important for people's lives pollination of agricultural crops. According to the labor of the bees gets an income of $ 15 billion. However, in recent years, beekeepers from different countries notice a mass extinction of these amazing insects. The reason for this phenomenon is considered to be a catastrophic amount of and active use in vegetable fields to deal with pests that also have a negative impact on beneficial bees. Recently it became known that the extinction of insects also fault stretched along the field lines.
In may 2018, the newspaper published the results of a study in which scientists have noticed that some groups of bees produce less food than others. It turned out that this is due to the presence between them and the source of food lines. Then the researchers could not determine the cause of this behavior of insects, but in the new scientific work that was given the exact answer — in the path line of bees causes them stress.
Today, the lines stretched almost everywhere
Dangerous power lines?
The fact that around the high-voltage cables for transmission of electric power is constantly there are very powerful electromagnetic fields. Scientists have long understood that their impact can feel the many living beings, but exactly how they affect the bees, all this time, remained a mystery. To find out, the entomologist Sebastian shepherd and his colleagues decided to conduct a little experiment. He was described in a scientific journal .
In the new science of bees exposed to electromagnetic radiation for 17 hours. This duration was chosen due to the fact that that's how much time the bees are sleeping in the nests, located under the wires of transmission lines on a meter height from the ground. After a set period of electromagnetic effects, the researchers tested how well the intelligence of bees. Inside a special container they tried to teach him to associate the smell of certain flowers with a faint but unpleasant for them shocks.
About bees exposed current
A Control group of bees that was not exposed to electromagnetic radiation the beginning to avoid "dangerous smell" after only five attempts. But the test group of bees learned to associate floral scent with a kick much longer. This implies that transmission lines reduce the ability of bees to learn, and hence reduce the chance to survive in difficult conditions. Besides, exposed to radiation, the bees showed more aggressive and often attack each other.
With all of this, Sebastian Shepard says that line . However, the fact that they have a negative impact on their health, no doubt. Perhaps in the near future researchers will consider the impact of electromagnetic radiation on bees, taking into account the harm used in the fields of funds against insects. It is likely that they will make very interesting discoveries.
It has become a tradition that at the end of the article, I recommend the documentary material on the appropriate topic. This time I want to recommend film production in 2012. The authors of this work are interviewing different scientists and describe in detail the life of these insects and their role in the modern world. The problem of extinction of bees in the movie, incidentally, is also affected.
