Experts say that wasps are beneficial insects, why do rural people say that wasps are pests?

Wasps are indeed pests for beekeepers, after all, eating bees is powerful, and it is seriously harmful to the beekeeping industry, but many friends ignore one point, that is, in addition to eating bees, hornets will also eat a lot of insects, so if we are not beekeepers, but farmers who grow crops, and hornets remove pests for our crops, then hornets can also be counted as beneficial insects. Regardless of whether an insect is a beneficial insect or a pest, if the number is extremely rare, then this insect naturally becomes a protected insect, after all, biological diversity needs species diversity to maintain, from the perspective of ecological balance, whether it is an animal or a plant, less is precious.

Experts say that wasps are beneficial insects, not that they have not been stung by wasps, but the farmer guesses that the main reason is that wasps are also useful. As mentioned earlier, wasps eat insects, but in fact, not only bees, but also some pests that harm crops are also the objects of hornets. Moreover, the wasp is poisonous, and it is also because of this that the wasp has a certain health care effect.

In the folk, there is the practice of making wine in a hornet's nest, and in addition, hornet pupae and hornets are all good medicines and health products.

Hornets are poisonous and will not actively sting under normal circumstances, but there will also be cases where humans mistakenly enter the territory of hornets and be stung in a mess, from this point of view, for people, it is aggressive, there is a certain harm, no one should like to be stung by wasps. It is a very common situation for hornets to eat cotton bollworms and armyworms, and attacking bees and humans is a very rare individual case, and like snakes, it can also be regarded as beneficial insects. Although the hornet is poisonous, it will not take the initiative to sting people many times, wild activities, find that the hornet frequently appears in your field of vision, you must be careful, pay attention to observation, find the hornet's nest in time, so as to turn around in advance to avoid being stung.

Wasps are poisonous and sting, which cannot be a reason for everyone to hunt and kill wasps, on the contrary, it is also a beneficial insect for humans, and we should protect wasps.

This is because many people have been stung by wasps, and they feel that after being stung by wasps, many people have been harmed by wasps, so they say that wasps are pests.

Because these insects can harm crops, especially fruits, eating fruits is very powerful.

Because it will cause harm to humans, and many melons and fruits may be affected, there is such a saying.

Wasps are beneficial insects because wasps eat insects that are harmful to crops and are good for the growth of crops.

I think the wasp is a beneficial insect because it is a pollinating insect that can help some plants impart pollen and make the plants flower and bear fruit, so it is beneficial and not a pest.

Although wasps sting, hornets are beneficial insects.

Wasps spread pollinating substances to plants, causing no other harm to the environment or people, and can effectively reduce the occurrence of pests and diseases.

They are beneficial insects, and they do not actively attack people, but are very diligent in spreading pollen.

They are pests because they bite people and pose a threat to people's lives and health.

Beneficial insects, if we are not engaged in the agricultural industry, the understanding of wasps is only an insect, from a broad sense of beneficial insects, hornets can prey on insects, can be regarded as beneficial insects.

If the insect is harmful to us and the number is large, in this case the insect naturally becomes a pest. Conversely, if an insect has little effect on us, or if it is still helpful to us, then this insect can be counted as a beneficial insect. Adult hornets like to prey on some insects, such as bees, which are the main targets of hornets.

So farmers say that wasps are pests, mainly because they often hurt people and are useless in the eyes of farmers. Rural called wasps, scientific name wasps, wasps, in a variety of bees, hornets are large and toxic, there are many kinds of wasps, there are as many as 200 species recorded in China, among the many wasp species, the toxicity is also different, the most poisonous sting 3-5 times can take a small life, and the general hornet, sting twenty or thirty times, ordinary people can not parry.

Armyworms and some moth pests, and can play a role in pollination, from these aspects of wasps are still very good beneficial insects, many agricultural growers will also raise a certain amount of wasps, the purpose is to use to eliminate pests in agriculture and forestry, to play a biological control pest effect. The main food of the wasp is the pest, and it has a wide range of food, especially for the flower pests of cotton.

Hornet pupae and wasps are highly nutritious delicacies and health products, and people are vying to taste them. In medical and health care theory, hornets are full of treasures. The bee venom of the wasp is superior to that of the bee and has a greater effect.

Bee pupae and beehives are all good medicines and health products, which have a good effect on human health.

Wasps are beneficial insects, they are like bees, they are a member of nature, and without them, there will be more pests. Our crops will be harvested less, and with wasps, we will use fewer pesticides, which will be healthier for our bodies.

The three drugs that hornets are most afraid of are methrin, cypermethrin, and permethrin, which can kill hornets, and at the same time are also the nemesis of Ma Feng bees, so we can also use these three pesticides in our daily life to drive away hornets. So what are these three pesticides, you can continue to read and understand.

1. Amethrin: It can affect the nerve center system of insects, can be used to control mosquitoes, flies, cockroaches and other health pests, has a strong knockdown effect, and can be mixed with health insecticides for human and animal safety when used to make aerosols to use.

2. Cypermethrin: It has strong toxicity, the appearance of the original drug is white to cream crystals, soluble in aromatic hydrocarbons, ketones and alcohols, and destroys the function of the nervous system by interacting with the sodium channel of pests, and can be used to control a variety of insects such as flies, cockroaches, mosquitoes, wasps, lice, etc. in public stool sanitation and animal husbandry.

3. Permethrin: It is a low-toxicity insecticide, characterized by its mode of action based on contact killing and stomach toxicity, no systemic fumigation, its insecticidal spectrum is extensive, can be used to control a variety of pests on fruit trees, and is also suitable for the treatment of wasps and other insects.

4. This method of picking the nest is most suitable for dealing with the hornet's nest that has not yet become a scale, and the specific method is to cover the hive with a bag at night or on a rainy day when the hornets are all returning to the nest.

There are these reasons why it is easy to attract wasps at home, one is that there is food in the house to attract wasps, such as all kinds of meat and ripe fruits, which are extremely attractive to wasps. Two:

There is a hornet's nest near the home, and the hornets are also prone to nesting, and if the distance is more than 500 meters, it may become lost. Three: The home environment is suitable for hornets to nest.

Four: There is a hornet's nest at home.

Wasps are beneficial insects. Wasps are not only the main way to spread pollen, but also feed on cotton bollworms, armyworms and other insects that are harmful to crops, and have a great contribution to crops.

Wasps are beneficial insects. In general, the benefits of wasps to humans outweigh the harm, and hornets mainly feed on cotton bollworms, armyworms and other insects that are harmful to crops. Distributed all over the world, it is intimidating to see.

about 16 mm long, antennae, wings and tarsal segments orange; The body is jet black and shiny, with yellow stripes and paired spots. Wasp stings are painful but not as toxic as common wasps.

Wasps are the natural enemies of bees, and some large hornets often fly to cities, villages, near houses and apiaries to catch bees, most of which are used to feed larvae and some to enslave and work.

Wasps are addicted to sweet substances, and ripe grapes, apples, pears and other fruits, as long as the fragrance is overflowing, will attract wasps to bite and cause reduced yields. In addition, wasps like to prey on larger pests, and rarely care about aphids, red spiders, etc., so when using wasps, it is necessary to pay attention to the application of other natural enemies such as grass ridges and ladybugs.

According to research by a team from the University of Michigan in the United States, hornets also reason logically, such as transitive reasoning. The reason why this ability has evolved may be because of the structure of society. Hornets spend a lot of time fighting for dominance, and transitive reasoning is very important to figure out the dominance relationship.

This type of study has been conducted on bees, but has not been found to use the same reasoning process. Perhaps this is because the same ruling class has not been formed.

Wasps are beneficial insects.

Wasps, on the other hand, feed mainly on small insects such as cotton bollworm and armyworm. This small bug is generally harmful to our food crops, so wasps are classified as beneficial insects.
