Description of the pest

Pear leafworm is a small insect that can jump and fly well. It appears immediately after the snow melts. The insect has developed wings. In winter, it hides under tree bark and fallen leaves.

• The body of an adult sucker (imago) in the summer is painted red-orange or green-brown with longitudinal light stripes on the abdomen.
• Transparent wings with dark orange streaks fold along the body. Closer to winter, the body becomes black.
• The head has a triangular shape. It has two large and three small eyes, and also has a proboscis, with which the insect draws juice from the green part of the plant.
• The length of an adult insect is up to 2.8 mm.
• Insect quickly jumps or flies from one tree to another.
• Each female is capable of laying between 450 and 1100 eggs. The eggs are oval, 0.4 mm long. First they are white, then they turn orange.

The larva goes through several stages in its development. Great harm to fruit trees is the larvae of the psyllid of the last phase of development (nymph).

Insects suck the juices from the plant and contribute to the development of a fungal disease. Therefore, it is so important to identify the problem in time and start the fight with proven and effective drugs.

Development cycle

For wintering, adults (their body is dark in color) go into cracks under the bark or under fallen leaves. As soon as the air temperature after winter is set at -1-2 degrees (approximately the last days of March), insects begin their active life.

When the air warms up to +5 degrees, the suckers begin to mate. Males die immediately after mating, while females live up to 46 days. The first laying of eggs at the base of the kidneys occurs at a temperature of +10 degrees.

The warmer the air, the faster the larva goes through all stages of its development. At a temperature of +10 degrees, the nymphs begin to appear after three weeks, and at a temperature of +23 degrees - after a week.

Stages of larval development:

1. The first phase is different in that the insect has a dark orange body up to 0.56 mm long with dark stripes on the back.
2. The size of the body reaches 0.73 mm, the color brightens.
3. The insect grows up to 1 mm, the body becomes a light gray hue.
4. The nymph grows to 1.37 mm, the body color is greenish-yellow, the outlines of the wings become visible.
5. Resemblances to adults appear. The size increases to 2 mm, the color of the body becomes brown-greenish.

What is dangerous insect

Reproduction of the sucker is most often occurs only on young, well-bearing pears. Nymphs suck juice from leaves, buds, pedicels and fruits. Excess juice you drink comes out as a sticky compound.

The affected areas become infected with fungal diseases, the immunity of the tree decreases, the buds, leaves dry up and fall off. Fruits that have matured grow small, misshapen and bitter.

Causes of occurrence

There are several unfavorable factors that contribute to the appearance of suckers on fruit trees:

• wet, warm weather favors reproduction;
• pear varieties with late fruit ripening are the most damaged;
