Wasps, along with bees, are valuable for the economy, ecosystem and human health.

We used to hate wasps and love bees, as the latter pollinate crops and produce honey. However, such

the division is due to ignorance of the role of wasps in the ecosystem.

Wasps are not well understood compared to othersinsects, only scientists are beginning to understand their value and importance, the authors say. In a new work, they examined the main functions of bees, as well as their global role in our lives.

Wasps are predators.These insects are biocontrolled and protect crops worth $ 416 billion annually. However, this figure almost completely ignores the wasp contribution.

However, these insects regulate populationsarthropods such as aphids and caterpillars that damage crops. Solitary wasp species tend to fight a specific pest, and groups of wasps hunt a large number of species at the same time.

Researchers say wasps can be usedfor pest control in developing countries, especially tropical ones. To do this, farmers need to bring populations of local wasp species to them: this can be done with minimal risk to the environment.

Also, wasps, along with bees, are pollinated.The authors write that they discovered how wasps visited 960 plant species, and 164 of them are completely dependent only on aspen pollination. These were, for example, some types of orchids.

Many wasps are also versatile.pollinators that roam a wide variety of plants, so the researchers say they could serve as backup pollinators if the plant loses its native primary pollinator.
