Everything has advantages and disadvantages. It is said that he is a beneficial insect because he feeds on the larvae of other insects. This is a beneficial insect, and its harm is mainly to domestic bees. In the past, the bees fed by my family were always taken away by him as food, so I hate it, too! It is also harmful to people. One of our young men went out to work, accidentally bumped into a hornet's nest, got stung, and then died of allergies!
Of course, as a wasp larva, eating it is also a good choice, but you have to consider whether you are allergic to high protein, and you can't eat it if you are allergic! In the biological chain, both are indispensable, and some creatures have both advantages and disadvantages. They have no subjective consciousness, as long as they are in their recipes, they will come to everything. But if nature lacks this link, it may cause a series of unpredictable chain reactions. But generally speaking, people can't provoke wasps for no reason. After all, wasps are a group, not just a few, so as long as you don't provoke wasps and stay away, there will be no attacks on people.
Wasp is a carnivorous and herbivorous animal. Why do you say that? Hornets will eat the same kind or the same kind of corpses, while herbivores will eat plants as food, which also shows the advantages and disadvantages. However, wasps still have a lot of use value and can be eaten. Bee pupa is a kind of edible insect rich in white paper and low in fat, with high nutritional value. It can also be made into medicine. The wasp larvae, adults and honeycombs can all be used in traditional Chinese medicine for oral administration and external application to treat poisonous insect bites, toxic furuncle and other diseases. The wasp can also be used to promote agricultural production, farmers can use artificial assistance to overwinter and build and move nests, and use wasps to control a variety of agricultural and forestry pests. Therefore, this problem cannot be generalized, but if you are a beekeeper, it is not an exaggeration to say that wasps are pests and beneficial insects.
