The Medvedka (from the Latin Gryllotalpa) representsa small insect. It can damage the roots and appendages of plants, fruits and bulbs, seeds. Fighting with a bear becomes for many gardeners a matter of paramount importance - it causes a lot of problems. For agriculture, three types of bear have become special pests:
The fight against the bear has its own difficulties - this isthe insect freely moves in the water, flies through the air at night, and in the earth it is better to orient the mole. She got her name for the awkwardness and dark brown body of adult pests. Young individuals, in turn, received the name "top" for the grayish color of young insects, and for the presence of claws and denticulate nail files - "earthen cancer." The insect bear winters remarkably at a depth of up to 120 cm. The presence of the pest on the beds is spoken by mounds of rolled clumps of soil. When the spring comes, the bear wakes from hibernating in search of food. In May, June, pests appear on the surface during the breeding season. The bear is an insect that tends to put as many eggs as possible. The nest for the future offspring is built at a depth of 10-20 cm, where dark yellow eggs are deposited (300-500 pieces). The brood appears after 2 weeks, settling in the garden, greenhouses and getting yourself food.
Fighting against a bear
One of their effective ways to control the pestis early and deep plowing and loosening of the soil to a depth of 15 cm. This method destroys the courses of the bear, it does not allow to obtain food for itself, it destroys the larvae. In order not to attract pests from surrounding areas, it is not recommended to feed the soil and plants with fresh mullein. To scare off an insect, you can breed a bird droppings, watering them in dry weather. Close the road from neighboring areas will help sown on the border of the marigolds, the smell of which does not bear the bear. Hunters pits are excavated in autumn, when the temperature of the soil drops to +8 degrees. The depth of such pits is 50-60 cm (2 pits per 100 sq. M.). On the walls of the pit a film is fixed and is filled with not completely destroyed manure. The bear-catches into the pits for wintering, and after the onset of persistent frosts along with the manure it is scattered on the surface of the earth, where it dies from the cold. Hunters are also prepared in the spring for catching larvae, filler is fresh manure or chopped straw. Also heaps can be scattered on the ground, where the bear will crawl for the next masonry. After hatching, the larvae do not leave the nests and feed on manure. After 3 weeks, the manure with the larvae is burned or scraped into special pits.
Chemical protection against insect pestsIt is used if other methods have ceased to be effective. The carcinogenic drug "Thunder" or "Phenaxin" in granules is filled up in the course of the bears and is covered with earth. The seeds of rye, maize, barley, wheat are steamed to swell and sprinkled with Aldrin (50 grams per 1 kg) and buried at a depth of 3-5 cm. This must be done before the emergence of young shoots, otherwise the bear will feed on young plants. Insects smell the bait and, eating, die. The dead pests are collected from the surface in order not to poison the birds. In summer, in the courses of the bear, pour a little sunflower oil, and then water. The insect creeps up and dies. You can catch pests in cans of water, buried at the level of the soil. You can also flood the courses of the Medvedka with soapy water, dissolving 50 g of detergent in the bucket of water or 10 g of laundry soap. A 0.5-liter solution is poured into the hole, after which the bear dies below the ground or is selected to the surface.
Thus, the fight against the bear is very real. It is necessary only to conduct it competently.
