What to do if aphids appear on the pear, how to treat and how to get rid of
Pear and other fruit plants are often affected by various diseases. The yield 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 the tree in order to get rid of it?
Insect description
Aphid is an insect with a small translucent body. It reaches 5 mm in length. It can be white, green, gray, pink and black. It is impossible to notice one individual, unlike the whole colony.The insect reproduces rapidly, covering branches, leaves and fruits. During the summer, there are 10 to 15 generations. 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 vital activity of insects. Aphids spread quickly with the help of garden ants. They feed on the excrement of the pest, so they are interested in moving it.
Ants protect the insect from enemies. To get rid of aphids, first of all eliminate the ants.
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 which species the insect belongs to, it has a woolen or waxy coating.
Pear is one of the favorite pest trees. Gall aphid prevents the growth of leaves and further contributes to their curling and falling off. Krasnogallovaya feeds on the juice of the formed shoots and foliage.
Signs of appearance
If aphids have settled in the garden, this can be understood by the following phenomena:
- a sweetish sticky mixture appears on the branches, leaves and the ground around the tree;
- leaves curl into a tube and dry up;
- buds and young shoots are covered with a dark bloom;
- flowers and ovaries fall off.
In places where aphids are biting pears, a purple tint appears. The liquid that covers the leaves and branches is called honeydew. Dark bloom on buds and shoots - sooty fungus.
Why is an insect dangerous?
The vital activity of aphids negatively affects the growth of the pear. Due to black bloom, the leaves lose their ability to photosynthesize. Over time, shoots and leaves dry out, the tree weakens and loses its frost resistance.
