Ground beetles: description

Speaking about what a ground beetle looks like, you need to know that the species of this beetle are diverse and we have up to 2700 of its subspecies. Differences will be in size - the size of the body, legs, antennae, color, some features of the development of insects.

Did you know? In total, more than 32,000 (!) Representatives of the ground beetles family are known in the world.

Often found garden ground beetle is a large moustached beetle up to 1.7-3 cm in length, of dark graphite color with a metallic luster. On the body on the flaps - small golden-dents and oblong grooves.It has developed strong legs that allow you to quickly and deftly move, and also, as the ground beetle is a predator, powerful strong jaws.

Features of the life cycle of ground beetle

Females lay 50 to 80 eggs at a time, choosing for this fertile, fairly wet area in the upper layer of the earth. Then the eggs appear from the larvae. With the passage of time (from 3-4 weeks and in some species up to two years), the larva of the ground beetle turns into a pupa, which then becomes an adult insect. Adult individuals are nocturnal - they hunt at night, but during the day they remain in shelter. What does the ground beetle eat and where does the ground beetle live? It feeds mainly on caterpillars, towaiting worms, slugs, snails, as well as small insects, flies, clams, seeds and plant roots. The dwelling where the ground beetle lives is either shallow soil layers, or on the surface at the base of grasses, bushes, under stones. Ground beetles live in small groups, which may include beetles of different species.

Did you know? Ground beetle is a long-lived beetle. Lives - 3-5 years and winter well, hiding under barns, warehouses, the foundation of houses.

What is the use of ground beetles in the garden, how to attract ground beetles

Ground beetles eat harmful garden insects, caterpillars, snails and slugs, which destroy home gardens and garden crops. The ground beetle is the easiest, natural and environmentally friendly way to combat these pests. That is, if the ground beetles are many, then you can do without chemicals and drugs to combat garden pests. And thus get a clean crop and avoid unnecessary spending on chemical protection.

Ground beetle saves the crop by destroying both mature pests and, in fact, does not allow them to multiply. Meanwhile, not all chemical products act equally well at different stages of pest development, and precisely because of this, it is necessary to do several sprays per season.

Important! AT an average of one ground beetle in the summer months kills from 150 to 300 larvae, pupae and adult caterpillars.

Therefore, these orderlies do not need to be destroyed, but on the contrary, it is desirable to increase their population in the area. If the question is how to quickly attract more ground beetles to your garden or garden, then, first, you need to create a habitat for them. To do this, leave at the site pieces of wood bark, piles of leaves, sawdust, small stones - all that will serve as a refuge for beetles. And secondly, if possible, do not use chemical pest control agents.Ground beetles are sensitive to chemicals that also have a destructive effect on them.

Who feeds on the ground beetle are birds, but they do it infrequently because of one particular feature of the beetles. At danger (as well as for immobilization of prey), beetles emit an unpleasant substance, so the birds try to avoid ground beetles.

Can a ground beetle harm the garden

For gardens, more precisely fields and crops, grain (black) ground beetle or hunchbacked pune is dangerous. And the reason is what this ground beetle eats. Instead of garden pests, it eats leaves, seedlings (larvae) and grain of cereals, and both cultivated, which is especially important, and wild. In addition to the fact that beetles eat grains, they sap an ear, and whole grains are showered on the ground. Approximate yield losses can be 30-35 grains in 10-12 days from one adult beetle.

The ground beetle on the description differs from the garden. It is richly black in color, smaller - 1.3-1.6 cm in length, with short brown or red antennae, perfectly adapted to the arid and hot climate. The peak of the invasion of bred beetles on crops - the end of May and the beginning of June.

Did you know? Black ground beetle can also affect maize. And sometimes with a shortage of food to survive, it can feed on weed seeds.

How to deal with ground beetle

The ground beetle pest is susceptible to the following insecticides - pyrethroids, neonicatinoids, organophosphates. These are chemicals used in the fields for spraying and seed dressing before sowing. There are also agrotechnical techniques, how to deal with black ground beetle. This is a complete harvesting of the previous crop, respect for crop rotation, deep plowing and plowing of stubble; additional cultivation is also desirable.

Farmers will not be superfluous to know about natural, accessible to everyone and harmless methods of pest control in gardens and orchards.
