Bees are known by many people for their production of honey and royal jelly. Like other wild pollinators, they have much more important roles. They are a very important link in biodiversity, especially in pollination, which is necessary for plant reproduction, but they are eliminated by the careless and wild use of many pesticides, including neo-nicotinoids: immidacloprid, chlothianidin, thiametoxam. Bees contribute to the pollination of plants, which has a positive impact on the environment. They contribute nearly 80% of the pollination of plant species and are therefore the essential link for the survival, evolution and reproduction of the world’s flowering plants. Agricultural production and the honey sector are also important agricultural sectors.
They are the ones who pollinate plants and allow them to reproduce and evolve. Without bees, many plant species would disappear from our plates, such as lemons, oranges, almonds, apples, zucchini, and many others. Their contribution to the United States GDP is estimated at about $15 billion. But unfortunately, they are threatened with extinction because of human behaviour including the abusive use of chemical inputs, deforestation, water, air and soil pollution. In addition, there are pathology, agricultural practices and a lack of food resources.
The consequences are problematic for pollination, which for millions of years has ensured the reproduction of 70 to 80% of the world’s flowering plants. In addition, more than 70% of crops, including almost all fruit, vegetables, oilseeds and protein crops, spices, coffee and cocoa, or 35% of the weight of what we eat, depend heavily or totally on animal pollination. In some parts of the world, such as Sichuan (China), the disappearance of pollinating insects forces farmers to pollinate manually, as all pollinating insects have been decimated by pesticides.
It should therefore be noted that the disappearance of bees and other pollinating insects would have a catastrophic impact on world agriculture: it would reduce agricultural production and increase food prices, worsening the current global food crisis. The results show that global food balances would be significantly altered for three categories (fruits, vegetables and stimulants) if pollinators were to disappear altogether: global production would no longer be sufficient to meet needs at current levels.
