Who is it?

Spider mite (lat.Tetranychidae) is an animal that belongs to the type of arthropods, arachnids, a subclass of mites. The most famous member of the family is the common spider mite. It is a pest of indoor, garden, agricultural crops. It is found on all continents where there is vegetation, except for Antarctica.

The main distinguishing feature of the spider mite is the ability to secrete a web, for which he received his name. With this thin veil, they wrap a plant in which they later live. Also, this species can change the green color to orange or red. It all depends on what the parasite eats and where it lives.

What are the reasons for the appearance?

Maintaining a collection of indoor flowers at the proper level requires constant replenishment. Infection may occur:

• upon purchase of a new copy;
• because of the bouquet brought flowers;
• during the exchange between flower growers sprouts;
• when a tick enters a room with wind through an open window or window.

Nothing to do here, because visually difficult to recognize the presence of a spider mite on a plant. At first, it can be inactive, being in a state of diapause.

Most often, the pest settles on plants with delicate and succulent foliage, in particular on indoor roses. And, as a rule, roses are grown in warm and dry conditions, mistakenly believing that this microclimate is as comfortable as possible for a flower. Meanwhile, such parameters are most successful for active reproduction of the spider mite. And if measures are not taken in time, then in a fairly short time all nearby flowers will be infected.

A harmful insect can also damage a flower if it is improperly looked after. For example, during the period of active vegetation, a rose needs a sufficient amount of water, with a lack there is a high risk of being hit by a tick.

Pest Description

Tetranychidae is an omnivorous pest that differs in its internal structure from insects. The length of the females is on average 0.5 mm, and the males are even smaller. Ticks have 4 pairs of legs, while sucking insects have 3 pairs. The body is elongated, flat, divided into three departments. It has no chitinous cover. The structure of the eyes is simple, there are two pairs of them. The spider mite sucking mouth apparatus.

Ticks live in colonies. One generation of spider mites lives from 12 to 24 days. The female lays over 100 eggs for her life. So for a year animals can leave from 8 to 18 generations. The higher the temperature and the drier the air, the more actively pests develop. Under adverse conditions, ticks fall into suspended animation, and in this state can be for a long time in dry leaves, earth, while not losing viability.

What is the danger?

The spider mite causes irreparable damage to the plant, up to death. On the leaves of a houseplant, it is placed on the back side, and the juice is sucked out. Depending on the number of individuals of Tetranychidae, one can judge the state of a room rose, but in any case it does not look healthy and blooming.

Initially, the pest damages the lower parts of the flower, then moves to the outside of the leaf plate. After damaging young sprouts. With mass settlement, pests destroy inflorescences and all non-woody parts of the rose.
