In natural nature, there is always a struggle for space and food. There are no winners in this fight. A biological balance is simply established when beneficial representatives of the fauna restrain the rate of reproduction of pests. And such pests, usually polyphagous representatives of the fauna, are capable of destroying huge areas with vegetables, grains and fruit and berry crops in a day. On cultivated lands, the true owners of gardens and vegetable gardens begin to fight with such pests in their own ways. In this article, we present to you six of the most dangerous pests of horticultural crops and measures to combat them.

1. Ticks are cosmopolitan omnivorous pests

Among the mites, the most famous and widespread are spider mites (Tetranychidae). Of the 50,000 species, more than 1,250 are found everywhere, including Antarctica. Spider mites are very small arachnids. Males 0.3-0.6 mm, females up to 1.0 mm. The body of a spider mite is rounded, covered with small bristles, sometimes with microscopic warts. On the head there are 2 pairs of eyes, the sucking mouth apparatus. The legs are five-membered. The body coloration of a spider mite is variable and depends on the color of the main host. Most often, ticks are red, green, brown, yellowish-green, dirty green in color.

By piercing the tissue, the spider mite sucks out the cellular contents.

Spider mite hazard level

Spider mites, accumulating a plant, are capable of completely destroying it in 3 days. The gluttony of ticks, coupled with the speed of reproduction (7 days pass from clutch to adult), cause literally epiphytotic damage to the leaf mass of green plants under optimal environmental conditions, which will never recover and must be destroyed.

To protect them from the environment, ticks braid their place of residence with a thin web (not all species). They live in colonies under leaves, lumps of earth. Eggs remain viable up to 5 years.

What crops do ticks infect?

All types of mites belong to the group of dangerous pests of garden and berry and park crops. Pests inhabit all plants, including flowering and indoor plants. They are especially attracted by all fruits, strawberries, beans, onions, jasmine, roses. From flowering - begonias, gladioli, tulips, hyacinths, orchids and others.

External signs of plant damage by ticks

On the leaves of an infected plant (in bright light), yellow spots, small holes, silvery traces (cobweb), a change in the color of the plant, and deformation of the leaf blade are visible. The defeat of plants by spider mites is usually epiphytotic.
