Bees are being drugged by pesticides

Resultado de imagem para ABELHAS MORTAS
Bees are insects that live in extremely organized societies, producing a series of substances very used by the man like the wax, the propolis and the main one: the honey. The bees collect the nectar from the flowers and store it in a structure of their body called the vesicle. In the hive, they produce some enzymes that react with nectar producing glucose and fructose, honey sugars as we know it. Millions of flowers are visited daily by the thousands of worker bees that live in a beehive. The bees act in a very radius of action in search of the nectar, reaching distances that can surpass the three kilometers of distance of the hive. But this large capacity of bees in collecting nectar, a fact of extreme importance in the potential of honey production, is becoming a big problem. A study carried out in Switzerland with 198 honey samples from all continents indicated the presence of nicotine-based pesticides in 75% of them, including samples of honey collected in Brazil. Despite these scary data, all samples of honey showed levels of these pesticides well below the permitted limits, according to European legislation. Approximately 10% of honey samples had four to five different types of neocotinoids. The samples of honey with the highest concentrations of this group of agrotoxic were collected in Europe, North America and Asia.But the most disturbing picture is with the insect. In several parts of the world, the bee population is decreasing mainly due to the indiscriminate use of agrochemicals, compromising not only the production of honey but also the pollination of most plant species. To make matters worse, another study in the UK has indicated that bees that are surviving are becoming addicted and dependent on this pesticide, just as nicotine vitiates smokers by acting on nerve receptors of insects. With this, bees are looking for exactly the flowers contaminated by these pesticides.
 
We are drastically altering the natural pattern of living things, and the worst: we have no idea of ​​the vast majority of the changes we make in the environment and social life of these insects. We need constant studies and research in these characterizations to know how to act in the face of this great environmental damage
