Leafworm: what kind of pest is it and how to deal with it


If the leaves of the plants curled up in a tube or formed a bunch around the inflorescence, there is almost no doubt that the plants in your area were attacked by a leaflet.

The pest, of which there are about 25 species, can significantly spoil the flora on the site. And in appearance he is more than modest - a nondescript butterfly, which you will not immediately notice. The main harm is done to her offspring, caterpillars. They can significantly harm the plant: destroy half of its fruits, buds and, so to speak, mutilate 60% of the leaves.

Description of Insect Pest

Leafworms are tortricides, a family of butterflies, among which there are completely harmless creatures, and those are also gluttons. Caterpillars of this butterfly eat almost everything indiscriminately: leaves, buds, fruits.

How to recognize a butterfly pest? Its wingspan reaches 30 mm, but can be half as much. By color, the insect may be light yellow, and may approach a brown color. But in general - the pest has colorful wings. The body of the insect is thick, the surface of the body is covered with a large number of hairs. The butterfly makes excellent use of its camouflage “robe”: during the day, it avoids appearing in prominent places, and in the evening it is remarkably hidden in greenery. Against the background of a tree, it's really difficult to see it. Therefore, it seems that this pest is almost elusive.

We have about 70 species of leaflets. But not all of them are harmful. But who in the first place should be "on the pencil" at the summer resident, is this:

  • mesh;
  • rose;
  • brown;
  • kidney
  • grape
  • subcrustal;
  • variegated gilded leaflet.

These uninvited guests appear in May and until August actively flutter in our gardens. During this period, they give two generations of offspring. The insect lays eggs already on the second or third day after arrival. Where exactly - it depends on the type of caterpillar. Someone exclusively on the buds and leaves, someone on the bark and branches. In one generation, the pest can lay up to 300 eggs.

Caterpillars appear already on the tenth day and immediately set to work. If the caterpillar appeared on a leaf, there it will live and eat. The insect has the ability to secrete a cobweb, with its help it folds a leaf across, with jewelry accuracy along the main vein. When the caterpillar is hungry, it will stick out of its house and bite off a piece of it. If you scare these insects, they will hang on a spider web on a leaf, and then will be blown by the wind to neighboring trees.

Damage to the leaflet

Note that this insect is not limited to harming only typical garden deciduous trees, but also spoils currants, apple trees, and pears. Gardeners are accustomed to such a separation of these pests:

  • shoots: harm young shoots of conifers;
  • codling moths: lay larvae where they have already done harm.

In order not to lose the crop (and these insects are famous for massive invasions), you need to regularly inspect the trees. If you see leaves rolled up by a cobweb into a tube, then the caterpillar has reached your possessions. If possible, it is better to immediately tear off the leaf, but hold it in your hand so that the caterpillar does not have time to crawl out. At an early stage of attack on plants, this method is effective.

How to deal with a pest

Fortunately, enough fighting methods. Consider the most popular of them.

Preventive method

So that the green leaflet does not have time to damage your plants, you can be proactive. Even before the buds bloom, the plants are sprayed with "Prophylactin". Experienced gardeners are advised to inspect the tree branches: if oviposition is noticed, they need to be cut and then destroyed. Among the preventive methods is the treatment of plants by Isegar. It turns out that the butterfly sits already on a poisoned surface.

Leaf picking

The simplest and most effective method. Saw leaflets folded into a tube, tear them and destroy. Hold the leaf tightly, otherwise the insect may slip and hang on the spider web. But if the plant is already damaged enough enough, this method will not work.

Chemicals

The most commonly used are: Accord, Aivengo, Fatrin. Means belong to pyrethroids, they work well if the air temperature fluctuates around 22 degrees. In warmer weather, the means of struggle will, alas, be ineffective. Do not use if the plant is slightly damaged.

Folk remedies

Opponents of toxic agents in their garden appear the following alternative. Even before flowering in the garden, you can spray:

  • infusion of tobacco;
  • infusion of wormwood;
  • infusion of tops;
  • infusion of tomato;
  • potato infusion.

After flowering plants processing is repeated. You can also fight directly with a butterfly: in the crown of trees, not lower than 1.5 m from the ground, a can is hung out, one third filled with some kind of fermenting liquid. The volume of the can is not less than a liter. The liquid may be bread kvass or, for example, dried fruit compote. Such lures are hung at night, this is a period of greater activity of the pest. Only in the morning the trap needs to be removed so that beneficial insects do not fall into it.

You can simply hang a trap belt from burlap on a tree trunk. It is cleaned after harvesting, and hung out in July. Subsequently, the belt is burned. This method works well, although it seems at first glance ineffective.

Day butterflies can be collected manually, they are inactive. True, they are problematic to notice on the bark of trees. We advise you to read the article on hunting belts that help protect the garden from pests.

And although this pest is considered a strong rival to the gardener, the struggle with the leaflet is not particularly difficult. And if you worry about the problem in advance, this misfortune of your site may not touch.

Have a good harvest!
