In any case, what is the purpose of the Hornets?

For those who ask what is the purpose of the Hornets, there is now a comprehensive answer. They are gluttonous natural enemies of pests. They can produce powerful antibiotics in their venom, pollinate plants, and even make nutritious snacks.

In the first major scientific review of the ecosystem services it provides, we revealed the benefits of hated insects to humans. It focuses on 33,000 known hunting wasp species, which carry st and live in every corner of the world.

Wasps and wasps are picnic pests that give wasps a bad reputation, and account for only a small percentage of all wasps species. But even they provide little-known help, such as hovering caterpillars on vegetable patches. Yellowjacket Venom is also being studied as a promising cancer treatment.

a lot of Insect population plummetedThreatening human well-being, but the wasp seems to be more resilient. However, even among entomologists, many people seem to avoid using them, and scientists say that more research is needed to understand them.

Professor Celian Sumner of University College London said: “When I tell strangers that I study the wasp, they will say: “Oh, what is the meaning of the wasp? “Why not learn about bees?” They are more useful. “Her previous research showed People hate wasps Because they don’t know what they did.

She said: “We are very satisfied with the idea of ​​bee sting, because we know that bees are performing well in the world.” “So we have collected evidence that can be used to put wasps on the map based on their ecosystem services. To give them more opportunities, wasps are as valuable as other insects like bees.

the study, Published in a magazine Biology Review, Analyzed 500 scientific reports on st bee. There are one hundred thousand known species of wasp, but seventy thousand are parasitic, stingless and well-studied. They have been used in agriculture without the use of pesticides to control pests. There are approximately 22,000 species of bees. Sumner said: “Wasps are the ancestors of bees, so bees are wasps that have forgotten how to hunt.”

The wasp is the top predator of the insect world.Recent studies have found that common Hunting wasps can control fall army insects Will attack the corn crops in Brazil and the borers that eat sugar cane. Scientists have found that the use of other predatory insects to protect crops is worth more than $400 billion a year, but hunting wasps has hardly been considered.

Yellow jacks and bumblebees are probably the most effective because they are social insects and live in large colonies. Sumner said: “So you have a lot of hunters going there and removing insects and arthropods.” About 1,000 species of hunting wasps are social. The rest are lonely.

“The lone wasps are super cool. Their venom contains an incredible cocktail that paralyzes their prey, and they also contain many antibiotics,” Sumner said. Many lonely wasps bury their eggs with their paralyzed prey to provide food after hatching. “Therefore, they want to ensure that food is preserved correctly.” The antibacterial properties of wasp venom, saliva and larval secretions have long been recognized in traditional medicine.

Sumner’s analysis found evidence that wasps visited at least 960 plant species, of which 164 were completely dependent on them for pollination. They include orchids, whose flowers attract male wasps by mimicking the rear end of female wasps.
