The vital role of bees in pollination and how to protect them

13/01/2024

Did you know that bees are responsible for pollinating 80% of the plants we consume? Different bee species, whether solitary or social, all play a crucial role in preserving biodiversity and our food supply. However, bees are currently threatened by factors such as pesticides, loss of natural habitat, and diseases. In this article, discover the importance of bees in pollination, different bee species, the threats they face, and measures to protect them. Learn how you can contribute to the protection of these essential pollinators for our planet.

Different bee species :

There are over 20,000 bee species worldwide. Bees are insects belonging to the order Hymenoptera, just like wasps and ants. Bees can be divided into two main groups: social bees and solitary bees.

Social bees live in organized colonies with a queen laying eggs and workers taking care of food, hive protection, and honey production. Well-known social bee species include domestic bees and bumblebees.

Solitary bees, on the other hand, do not live in colonies. Each female lays her own eggs and cares for her offspring alone. Solitary bee species include mason bees, leafcutter bees, and carpenter bees.

The crucial role of bees in pollination :

Bees are important pollinators for many plants. While collecting nectar and pollen, bees inadvertently transfer pollen from one flower to another, enabling fertilization and the production of fruits and seeds. About 80% of flowering plants depend on bees and other insect pollinators for reproduction.

Bees are particularly crucial for the pollination of food crops. Crops such as apples, cherries, strawberries, tomatoes, peppers, and squash rely on bees for pollination. Without bees, the production of these crops would be significantly reduced.

Threats to bees :

Unfortunately, bees face numerous threats that endanger their survival. The main threats to bees include habitat loss, pesticide use, parasites, and diseases.

Habitat loss is a major threat to wild bees. Bees require diverse habitats for food, shelter, and reproduction. However, bee natural habitats are often destroyed by urban growth, intensive agriculture, and deforestation.

Pesticide use is also a major danger to bees. Pesticides are used to protect crops from pests and diseases, but they can also harm bees. Pesticides are absorbed by plants and transferred to pollen and nectar, which can poison bees that consume them.

Parasites and diseases are also threats to bees. Parasites like varroa, a mite that feeds on bees, can weaken and kill entire colonies. Diseases such as American and European foulbrood pose additional threats to bees.

Measures to protect bees :

Fortunately, there are measures we can take to protect bees. Here are some of the most important measures:

  • Planting flowers : Bees need food to survive, so planting flowers that provide nectar and pollen is an excellent way to help them. Choose native flowers adapted to your climate and avoid plants treated with pesticides.
  • Avoiding pesticides : Avoid using pesticides in your garden or lawn, or choose organic products safe for bees.
  • Protecting bee natural habitat : Protect bee natural habitats by preserving wild areas and avoiding deforestation.
  • Supporting beekeepers : Beekeepers play a crucial role in bee preservation. Buy local honey from responsible beekeepers and support research and training programs for beekeepers.
  • Raising awareness : Raise awareness among your family, friends, and community about the importance of bees and the threats they face. Encourage others to take steps to protect bees.


In conclusion, bees are important and essential pollinators for our planet. Different bee species, whether social or solitary, all have a crucial role in plant pollination. Unfortunately, bees face many threats that endanger their survival, but we can all take measures to protect them. By protecting bees, we also safeguard our environment and future.
