Pesticides cause abnormal growth of the brain in bees
Source:
The Bees are disappearing. Well-known that this sad fact is directly linked to the use of pesticides, actively used in modern agriculture. Anyway, a long time researchers could not understand the mechanism of action of chemicals on the insects, considered to be one of the most important to humans. According to calculations, the planet will completely lose bees after 25 years, which in turn will entail not only decrease the amount of honey on store shelves, but will also reduce the production of world food supplies up to 75%, because bees perform an important function in the reproduction of crops. For a more detailed study of the causes of death insects, scientists have conducted a number of studies that have shown that pesticides can affect , causing a decrease in its activity.
Why bees are dying?
Bee — important to the global ecosystem organisms, about the incredible level of intelligence which we have already written in our articles. Despite its tiny dimensions, the bees manage to make a crucial contribution to the wellbeing of many ecosystems, while carrying out only one function — the function of pollinators. In carrying out its main task, the bees help to reproduce and grow plants, thus providing a direct impact on humans. Unfortunately, according to experts, currently, there is not only decrease the quantity and quality of agricultural crops, but also of pollinators, because some species of bees are already on the verge of extinction. The first article about the impact of chemicals on insects was published in the journal .
Deciding to examine the impact of pesticides on the brains of bees, scientists have identified several pupae of bumblebees feeding them for feeding nectar is contaminated with pesticides. Subsequently hatched bees were scanned using the technology of micro-computer tomography, but the results of the conducted experiment does not please the animal rights activists: the brain of young bees could not develop properly. The result is damage to an area of the brain responsible for learning, bees were no longer able to fully perform its functions, thereby undermining the survival of the entire colony.
computed tomography of the brain of the bumblebee showed abnormalities in the area responsible for learning
After analyzing the results of computed tomography, the researchers also found that groups of bees, which for a long period of time were exposed to pesticides had an abnormal brain structure. The so-called “mushroom body”, which is responsible for the ability of bees to learn, showed significantly smaller size in comparison with other groups. Experts also managed to come to the view that a colony of bees which were exposed to the pesticide exposure from the earliest age, was marked by a very weak learning ability. After repeating the scan, the scientists noted that the brain of the larval groups did not change even after complete elimination of harmful substances from the diet of insects.
It is Worth noting that pesticides are a bad influence not only on the body of bees, but also on us. Daily eating of fruits and vegetables and even various types of cereals, we can get symptoms of poisoning if the concentration remaining in the food chemicals would exceed the maximum rate. However, despite the toxicity of the additives used, farmers still actively used support mixture to protect their fields against disease and to stop, unfortunately, not going.
Pesticides destroy the faithful helpers of man — of bees,
