Description of the insect
Aphids are insects with a small translucent body. It reaches 5 mm in length. May be white, green, grey, pink and black. It is impossible to notice one individual, unlike an entire colony. The insect reproduces quickly, covering branches, leaves and fruits. During the summer, 10 to 15 generations occur. The female lays up to 60 eggs.
Causes of aphids
When the summer weather feels warm outside, aphids multiply. Rare rains do not interfere with the life of insects. Aphids spread quickly with the help of garden ants. They feed on the pest's excrement, so they are interested in its movement.
Ants protect the insect from enemies. To get rid of aphids, ants are eliminated first.
Pest varieties
There are a large number of aphid species in nature. 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 waxy coating.
Pear is one of the favorite trees of pests. Gall aphids inhibit the growth of leaves, further causing them to curl and fall. The red gall feeds on the sap of the resulting 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 ground around the tree;
- the leaves curl into a tube and dry out;
- buds and young shoots are covered with a dark coating;
- flowers and ovaries fall off.
Where pears are bitten by aphids, a purple tint appears. The liquid that coats leaves and branches is called honeydew. Dark coating on buds and shoots is caused by sooty fungus.
Why is an insect dangerous?
The vital activity of aphids negatively affects the growth of pears. Due to the black coating, the leaves lose their ability to photosynthesize. Over time, the shoots and leaves dry out, the tree weakens and loses its frost resistance.
Methods for controlling aphids
Depending on the scale of the infestation, aphid control is carried out using different methods:
- chemical;
- biological;
- folk remedies.
The group of main methods of insect control also includes prevention. The event is considered no less important. The final result depends on the correctness of a person’s approach.
Chemicals
The essence of the method is to spray the pear with insecticides. It is distinguished by its speed of action and efficiency. When using medications, safety precautions are followed.
"Fufanon"

"Aktellik"
One of the best preparations for treating pears against insects. Aphid colonies die 3 days after spraying the tree. The effectiveness of use lasts for a month. During this time, the aphids completely die or leave the garden.
"Bankol"
Refers to intestinal agents. Remains in the tree cells for a long time and retains its strength. “Bankol” is recommended to be used during the flowering of pears, so that before the harvest the chemicals leave the tree and the fruits are edible. Spraying is carried out before rain. Moisture does not wash away a significant portion of Bankol from leaves, branches and flowers. The cost is low, so it is available to every buyer.
"Aktara"
Systemic action against aphids.The result of application appears a month after spraying the tree. Remains on branches and leaves after rains. "Aktara" destroys not only aphids, but also other insects that have settled on the pear.

The resulting solution is diluted with 12 liters of water and grated soap is added.

Preventive measures to protect pears
Gardeners often try to protect trees from aphid infestations. To do this, do not neglect the rules of prevention:
- In late autumn, the bark is cleaned of contaminants and treated with antiseptic preparations. The tree trunk circle is dug up, and the bark near the base is whitened.
- It is useful to pour boiling water over the pear bark and the soil around the tree. A simple step can help get rid of pest eggs.
- In spring, a sticky belt is hung on the tree to protect it from pests.
- When the buds have not yet bloomed, the tree is sprayed with insecticides. This allows you to destroy the first insect larvae.
Prevention does not imply complex actions on the part of humans. If everything is done correctly, the gardener will not have to fight aphids during the season. This way the harvest will be preserved.
