Anonim

Pear and other fruit plants are often affected by various diseases. The productivity of trees and bushes depends on this. Insect pests also cause a lot of trouble. With the appearance of aphids on a pear, the question arises - how to process a tree to get rid of it?

Insect description

Aphid - an insect with a small translucent body. In length reaches 5 mm. Available in white, green, grey, pink and black. One individual is impossible to notice, unlike a whole colony. Insect breeds quickly, covering branches, leaves and fruits.During the summer, from 10 to 15 generations occur. The female lays up to 60 eggs.

Causes of aphids

When summer warm weather is felt outside, aphids breed. Rare rains do not interfere with the life of insects. Aphids spread quickly with the help of garden ants. They feed on the excrement of the pest, so they are interested in its movement.

Ants protect the insect from enemies. To get rid of aphids, ants are eliminated first.

Pest varieties

In nature, there are a large number of aphid species. The insect can be white, black, gray, brown, pink and other colors. Depending on what species the insect belongs to, it has a woolen or wax coating.

Pear is one of the favorite trees of pests. The gall aphid prevents the growth of leaves and further contributes to their twisting and falling off. The red gall feeds on the juice of the formed shoots and foliage.

Signs of appearance

If an aphid has settled in the garden, this can be understood by the following phenomena:

  • a sweetish sticky mixture appears on branches, leaves and the ground around the tree;
  • leaves roll up and dry;
  • buds and young shoots covered with a dark coating;
  • flowers and ovaries fall off.

A lilac hue appears in places where aphids bite the pears. The liquid that coats leaves and branches is called honeydew. Dark coating on buds and shoots - sooty fungus.

Why is the insect dangerous?

The activity of aphids negatively affects the growth of the pear. Due to black plaque, the sheets lose their ability to photosynthesis. Over time, the shoots and leaves dry out, the tree weakens and loses frost resistance.
