Appearance of a medvedka in a garden plot and garden
Adult insect in warmface or in the country
Let's start with a description. Recognizing an ordinary medvedka in appearance among other insects is not difficult: The size of an adult individual is from 3 to 5-6 cm, and sometimes even reaches a length of 8 cm, depending on the conditions of its habitat and “food”.This voracious pest eats everything in its path underground - the roots of plants, the seeds of freshly sown crops, even small insects. Where is the parasite and where does it come from?
How old is living? The whole cycle of life takes about 3.5 years. Appears usually from neighbors - careless gardeners.
The bear looks rather noticeable and frightening:
- the head and chest are covered with a common shell of dark brown color;
- has long whiskers, short tentacles and eyes on the head;
- soft belly, not protected by armor, three times longer than the cephalothorax;
- located at the end of the abdomen processes, resembling a mustache;
- wings long, thin, with scales;
- has 3 pairs of limbs: the front are short, thickened, covered with armor, resemble the claws of the crab, the middle ones are short, the back ones are long.
. Strong front claws and a shell-headed cephalothorax allow an insect to pull out long passages under the ground. In addition, the bear flies perfectly and even swims. She is mainly nocturnal, so she is not afraid of birds. In the evenings, when adult individuals crawl out of the ground and begin to fly from place to place, they make a sound very similar to the chirping of grasshoppers, only louder.
Determine that a pest has started up in the garden will help wilted plants. If the soil is not over dried, and the plants still die, you need to carefully inspect the surface of the earth. It is especially good to do this after a rain, then the moats, holes and loose hillocks of the earth dug out by the Medvedka are clearly visible.
As pest larvae look like
These mounds are most likely nests with laid eggs. To discover and destroy them is of paramount importance, since the development of the larvae occurs very quickly. And very soon hundreds of new voracious insects will grow. The nests are located at a depth of about 15 cm, during the day the medars usually “sit” inside, and in the evening they begin to move to the surface, destroying everything in their path.
The breeding period is at the end of May - the beginning of June, during the period of active work in the garden. If you stir up the nest, you can find a huge clutch of eggs, 500-600 pieces, which look like hemp seeds, which turn into larvae on days 14-17, which are already capable of causing significant damage to the garden.
Larvae have almost the same appearance as an adult individual, but still without shell and wings. They very quickly grow to 5-30 mm in length due to the fact that they feed on any vegetation on the site and cause significant damage. And then able to lay hundreds of new eggs.
How dangerous is the bear for vegetable crops
The pest beetle is equally dangerous for most vegetables and root crops. Powerful jaws allow Medvedka to easily finish off not only the root system of corn, cabbage, cucumbers, tomatoes, peppers, eggplant, but it is also easy to gnaw out significant pieces of root crops - potatoes, beets. Medvedka can completely destroy the seeds of carrots, radishes, and especially - cucumbers sown in the ground, damage the roots of garden strawberries, flower bulbs, roots of shrubs and underground stems.
Do not disdain this omnivorous predator and its own kind - they eat smaller insects living in the ground, worms, dragonfly larvae and ladybirds.
can start. Measures to combat the pest at different stages
Fighting a predatory pest, its complete extermination at home gardens is very laborious and troublesome. This is not a simple insect - the bear constantly changes its location, digs holes and passages and requires a sufficient period of time to track it down. Therefore, the most effective will be a comprehensive struggle with it, in several ways.
There are many fairly effective methods of dealing with this scourge, which can be divided into two types:
- extermination of polar bears with the help of toxic chemicals;
- insect extermination by environmentally friendly folk remedies.
Chemicals to destroy the beetle and protect the crop.
There are a number of the most potent chemicals that destroy Medvedka very effectively: Prestige, Medvetoks, Fenoxin Plus, Thunder, Aktar 25 WG, Bankol,"Parachute".Instructions for use are on each drug. The principle of operation is the same: the pesticide granules fall asleep into insects and / or nests dug by insects. Adults and larvae will die within 24 hours.
You can make bait and mix it with the drug. As bait will serve barley, wheat porridge, mixed with beer ( !) .A mixture of all the ingredients is rolled into balls and laid out in places of numerous passages, holes with larvae and insects, in the inter-row of beds that need protection - cabbage, tomato, cucumbers, potatoes, and root crops. An excellent bait is the mixture of chemical preparations and germinated seeds of cucumber.
As a chemical, you can use kerosene, zinc phosphide, hexachlorane. In the greenhouse, the control measures are similar.
How to deal with meddar effective folk methods
The principle of extermination is the same: to find a hole or aisles, lure the smell of bait and destroy the pest without harming the environment and themselves. Or, on the contrary, expel the bear by means of substances with a strong odor, which they do not tolerate. Here are some popular recipes widely used by gardeners:
- With ammonia .4 dessert spoons of sal ammoniac add to 10 liters of water, water the plants under the root with a solution( 0.5 liters for each), trying not to fall on the leaves. The smell of ammonia repels the bear, while the solution serves as a nitrogenous feed for the plants. The only drawback is that it quickly disappears, so it is advisable to repeat the procedure every 7–10 days. It is possible in the aisle to lay out the rags of cloth or rags dipped in ammonia water. The tool is not able to completely kill the beetles, but for some time just scare them.
- manure trap. Fresh manure( chicken droppings) acts on a bear like valerian on a cat. Therefore, they do not need to fertilize the land, but it will be very useful to make 1-2 traps for 1 weave. In early May, small piles of fresh manure spread out in the garden. After 15-20 days, you can check - surely there will be adult individuals and eggs laying. It will remain to take them away and destroy.
- Shadow Traps .Pieces of roofing material, cardboard, sheet metal, etc.spread out in open sunny places. In the daytime, Medvedki will surely climb under them, they can be easily destroyed, only you need to act quickly, without delay.
