General description of the insect

The common bear is a very harmful and rather resistant orthoptera insect from the bear family. This species inhabits the soil, laying rather long and deeply penetrating passages in it, ending in a nest. If you literally translate the word "bear" from Latin, then it sounds like a little cricket.

Indeed, in its way of life, this insect strongly resembles a mole. And the appearance of the bear adds significant similarities to them. The body length of adults of this species can reach up to 5 cm. If we consider the insect in proportion, then the abdomen turns out to be about 3 times larger than the cephalothorax.

At the end of the abdomen, the bear has a pair of filamentous cerci. The front of the insect is protected by a hard shell.

The bear can partially hide its head in it. On her head, paired eyes of a complex type, a rather long mustache and two pairs of tentacles, which serve as a frame for the mouth apparatus, are clearly distinguishable. The front pair of insect legs is ideal for digging soil.

Adult bears can fly quite successfully. But for this they definitely need warm air. Medvedka in Russia is widespread almost everywhere, with the exception of the northernmost regions. Also, this pest is found almost throughout Europe, in most of Asia and North Africa.

Biological features

Most often, the bear can be found on light sandy and sandy loam soils with moderate moisture. Too hard or too dry soils, this insect tries to avoid. Most of the bear's life cycle takes place under the soil surface. It comes to the surface quite rarely and mainly at night. For wintering, this insect goes to a depth of 2 meters.

The basis of the bear's diet is the roots of plants, as well as small earthworms and other insects. At night, you can hear the characteristic chirping of the males of this species. To do this, they build burrows widening towards the entrance, which greatly enhances the outgoing sounds.

Of the interesting features of this insect, it can be noted that adults can swim very well. The bear also has natural enemies with parasitic flies. For her laying of eggs, the female bear equips a nest, which is located close to the soil surface.

It can often be seen by its characteristic domed vault, which protrudes quite strongly above the ground. This is done so that the eggs are better warmed up by the sun's rays. One clutch can contain several hundred eggs at once. The larvae develop into an adult insect over several years.

Folk methods of struggle

The fight against the malicious bear has been going on for centuries. Of the most common folk methods, the following methods can be noted:

  • Beer trap
  • Manure trap
  • Water trap
  • Washing powder and soap

Beer trap. Suitable for the destruction of the bear in the summer. To make it, you need a 0.5 liter glass jar and some beer. The can is dug into the soil in an inclined state so that its neck is below the level of the soil surface.

The resulting recess with a protruding neck is closed with a sheet of slate or other available material. Water trap. As you know, the bear always goes to places with high humidity. Therefore, a can of water dug into the ground is quite successfully used to destroy it.

Autumn dung trap. Its principle of operation is based on the fact that in search of a place for wintering, bears very often climb into heaps of manure or compost. To arrange this trap, a hole about 60 cm deep is dug in the soil, which is then filled with manure or compost. Before the onset of severe frosts, the contents of the pit are removed, and the bears and their larvae found there are destroyed.

A solution of washing powder or soap. Some gardeners prefer not to bother constructing traps. To remove the bear, they use a solution of soap, which is poured in huge quantities into the holes of insects. In most cases, the effectiveness of this method is highly questionable.

Passive methods. Of the methods that do not require direct intervention, the sowing of strong-smelling crops should be mentioned. For example, for these purposes, you can use the well-known marigolds or marigolds.

Natural enemies. Also, some gardeners who are adherents of organic farming attract natural enemies to fight the bear. For example, hedgehogs, shrews or starlings.

Using barriers. They consist in protecting the root system of plants with plastic. Most often, plastic bottles are used for this, which are cut into rings and put on the roots when planting.

Insecticide control

The most effective way to kill a bear is to use special insecticidal agents. Special granular baits have proven themselves best. For example, Medvetox, Fenaxin or Thunder are highly effective.

They are scattered in the places of the passages and slightly embedded in the soil. Mass death of insects occurs rather quickly; in most cases, the next day, dead insects can be found on the soil surface.
