Wasps in the garden: helpers or enemies

Everyone knows these striped black and yellow insects that live in gardens, in personal plots, the main place of accumulation of which is containers of water, stinging very painfully all who disturb their peace. Gardeners, with varying success, are fighting wasps in their plots, reaching the use of poisonous substances. But is it necessary to destroy wasps?

Are they enemies or friends?

To begin with, there are many varieties of wasps, some attack themselves, others will not bite, even if you try to provoke them. The main thing is to know which wasps are especially poisonous and which are not.

What is the use of wasps

The wasps themselves are "herbivores" and feed on fruits, honey, jam and other sweets. But their larvae are real predators and feed adult cubs with various harmful insects and their larvae. Each type of wasp destroys certain pests. Let's take a closer look at what wasps exist, how they are useful, what types of harmful insects and larvae destroy and how they are dangerous. And in general, are they dangerous?

Paper wasps

Let's start with the most common type of wasp - paper wasps. There are more than one thousand of their varieties; more than 30 species live in Russia. These are the same wasps that sting painfully, live in attics, build houses for themselves, fly into the kitchen to smell of jam, spoil the fruit harvest and cause other harm. They are also very dangerous for apiary owners, as they destroy bees.

These wasps got their name due to the fact that they build houses from paper, which they themselves make from wood. They raise their offspring in these houses. By the way, over the summer, 1 wasp swarm can give birth to more than 4 thousand new individuals that leave their native nest, build their houses and again give birth to more than 4 thousand young wasps!

The benefit of this type of wasp lies in the fact that they feed their offspring with flies, ants, caterpillars, bees and other various crawling and flying insects. The main condition for these wasps is that they must have enough strength to defeat the "enemy" and bring the future food to the nest.. That is, if there is a swarm of wasps on the site, you will significantly reduce the number of harmful insects, and you do not need to use various pesticides. But against aphids, these wasps are useless, since adult insects feed on the secretions of aphids and, accordingly, do not destroy aphids.

Wall wasps

This species of wasps is very close relatives of the well-known paper wasps. They got their name due to the fact that they build their houses mainly on the walls of various premises. Unlike paper wasps, these wasps do not live in swarms, they are single wasps. They feed not only on fruit juice, but also on insects, as well as spiders, sometimes even the remains of vertebrates. They feed their larvae the same, with the exception of plant food.

Thus, on the site, these wasps will destroy various spiders and insect larvae, including the larvae of grinders, elephant beetles, leaf beetles, as well as caterpillars of leaf rollers and moths.

Scolia wasps

These Sami are large, ranging in size from 1 to 10 centimeters, and the most peaceful wasps. Such wasps will not sting even if a person picks them up. They use their sting only for their intended purpose - they prepare food for their larvae.

These wasps live in burrows in the ground in warm regions, as their larvae cannot develop in cool soil and will simply die. Despite its non-aggressive nature, this wasp is often attacked by people who are afraid of its size. By the way, scolia was included in the Red Book of the USSR and certain regions of Russia.

The diet of the larvae of these wasps includes the larvae of rhinoceros beetles, bronzes and beetles. By the way, there are cases when scoliosis was specially brought to some places, for example, to the islands of Hawaii and Mauritius, in order to destroy beetles and rhinoceros beetles on them.

Therefore, if you see a flying "helicopter" - an os of impressive size, do not be afraid of it and do not seek to destroy it, because it is extremely
