General reference

According to the general encyclopedia, scale insects are small semi-winged insectsthat are part of the superfamily of worms. This name is due to the presence of a hard coating of the body, resembling a shield.

This peculiar carapace consists of 1 or 2 connected skins, under them there is a wax secretory part (scale insects release adhesive liquid). False shields do not have a hard shell. Instead, insects have a thin shield formed of dying skin. Insects do not emit liquid, but inject poison into the plant.

REFERENCE! The carapace of the guards is part of the body; it is firmly attached to the body. In false shields, the shell is thin, it can be easily lifted. The sticky substance secreted by scabs provokes the onset of soot rot.

What types exist?

In nature, there are more than 2,000 species of scale insects and false shields. They are united by the fact that they are all pests for indoor and garden plants. The main differences for classification are color, size, object for parasitism. Our climate is characterized by such species:

• brown - affects ornamental plants;
• yellow and red pear;
• Rosanna - lives on blackberries and rose bushes;
• willow and poplar;
• Californian - can parasitize on 200 species of plants.

What does it look like?

The average size of the insect is 2.5 mm. Female scale insects (or shield aphids) are characterized by absolute immobility. On orchids, they look like small tubercles or warts. Males can fly, but their life span does not exceed 7-8 days. Both moths and mockworms males have 2 front wings. The female scabbard can be recognized by the presence of a translucent carapace that covers the body. Its color varies by species.

What danger is an insect?

Scale shield provokes the onset of soot rot:

1. The insect secretes a sticky liquid, which is an ideal medium for the appearance of fungi.

3. False shield injects poison into the orchid, under the influence of which the leaves become covered with colorful spots.
4. As the area of ​​such spots increases, the sheet dies.

An affected plant is an excellent food for ants. The pest larvae quickly spread and infect neighboring bushes.
