The benefits and harms of the wasp are related to its food preferences, lifestyle. Unlike bees, insects are not loved by man because of the aggressive nature, painful bites, sabotage on the dacha.

There is a huge variety wasp, different way of life, behavior, strength of poison.

Benefit or harm

Wasps on the dacha

Adults eat nectar, bee honey, juices of ripe fruit, some vegetables. And also lemonade, kvass, beer. Protein food is required for feeding the larvae. Often, wasps can be found near meat and fish.In the wild, they hunt spiders, small and large insects. From here there are useful and harmful qualities of insects.

In the summer cottage from the nest and a large number of striped individuals get ridto avoid bite damage to the crop. Insects are especially dangerous for grapes. What do wasps with berries: just pierce them, suck juices. But they have a peculiarity not to eat one, but to damage different ones. At the puncture site, the berry begins to deteriorate, rot. Several dozen wasps in a vineyard can cause significant damage to the crop. To fight insects on grapes man uses special bags, traps, insecticides.

Dangerous settlement wasp family in the country, where there is an apiary. Predators are not averse to be fed with honey, and bees carry off their larvae to feed. A massive attack can destroy a beehive in half an hour. Beekeepers to trap predators place traps, destroy the nests mechanically - pour boiling water, burn.

Why do I need wasps

There is nothing superfluous in nature. Each insect performs its functions, which are regarded by man as benefit or harm. Wasps are needed in nature to regulate the number of insects - small, large. Scientists say that in the absence of the wasp family, a person would find out about such numbers of insect pests that they are not aware of right now.

A flexible body structure, powerful jaws, a sting with poison help skillfully cope with any prey, even one that is several times larger in size than the predator itself. If the public wasps destroy many different insects, the solitary choose one species or several. It is better for humans to find pests, their larvae under the ground, used as a live incubator for their larvae.

What is useful wasps of different species:

• Digging Larra hunts exclusively on the bear, with which a person is a continuous struggle on their site.To other representatives of the fauna indifferent.
• Digging wasp Ammofil - A single sandy wasp that destroys the larvae of the moths, which during mass reproduction destroys crops at a rapid pace.
• Giant scaled regulates the number of May rhinoceros beetles, Khrushchev, bronzovok. Despite the awesome appearance, a bite for a person is not dangerous.
• Tiny Spilomena troglodytes lead a desperate struggle with thrips, affecting garden, garden, decorative flower cultures.
• The benefits of social wasps - polistov, vespinov with a characteristic yellow-black color, are somewhat larger. They destroy spiders, leaf wrenches, larvae of moths, bronzovikov, gadflies, weevils, grasshoppers, locusts, bugs, leaf beetles. In urban environments - is the only large-scale enemy of flies.

Different kinds of wasps

This is not a complete list of potential victims of the wasp family. The location of the nest on the summer cottage can do more good than harm. If the hive is located far away from the garden, the vegetable garden does not particularly hinder, it can be used for your own benefit In autumn, the nest will become empty by itself.

On a note!

Why do we need wasps in nature even to pollinate plants, increase the yield of berries, vegetables, fruits, and provide beautiful flowering to ornamental crops. The wasps help to decompose the carcasses of animals, insects, carrying away protein foods to their larvae. The value of them in nature is underestimated by a person, therefore it is biased. But there is a reverse side of the coin.

An excessive increase in the number of the wasp family is a dangerous mass attack on the apiary, people's bites, damage to fruits and berries. Helping to regulate the number of insects birds, animals, the largest representatives of the same wasp family - hornets. The main regulator and enemy for insects is a person with insecticides. Due to rash actions, some species of wasps are listed in the Red Book as disappearing from planet Earth.
