Leaf rolling on an apple tree is very common. It belongs to the Lepidoptera family of insects. Approximately twenty-five species of such insects are found in the gardens of Our Country. Among them there are also very harmful varieties. These include grapevine and oak leaflet. Their activity begins in early spring and ends in late autumn. There are many different ways to fight and some of them are really useful.
Appearance and description
You can distinguish a leaflet on an apple tree by its appearance. If other insect pests fold their leaves vertically on their backs, then the leaf roller folds them horizontally. Externally, the leaflet can be distinguished from other butterflies by common features, and the first of them is described above. However, different species have different colors, and each can be described separately.
- Cluster leafworm – the front wings are brown, decorated with a characteristic pattern of light stripes located transversely. They are also diluted with yellow and blue faint spots.
- Eastern codling moth – wings are dark brown, shaded with white strokes in seven pairs along the front edge. The tip of the wings is bordered with a black velvety line, and the hindwings are lighter, brownish-gray.
- Hawthorn leafworm – gray-brown front wings, in males they are yellowish. The pattern is dark brown, in the male it is distinguished by a clearly visible light tone. In females, the pattern is blurry. The hindwings are monochromatic, while females have a reddish coating.
- Pear codling moth – dark gray front wings, transverse wavy lines are clearly visible on them. The upper edge of the forewings has a brownish-brown spot. Hindwings are dark, brownish-gray. So the pest, the photo of which is presented below, primarily negatively affects the leaves and buds, and it can also damage entire inflorescences. The fringe is grey, with a prominent dark line at the base.
- Oak codling moth – pale green wings, sometimes yellow-green. Both pairs with blurry edges. They have a yellowish head and a gray abdomen, reaching eight centimeters in length.
- Plum codling moth – the front wings are gray-brown, with a purple tint. Mirror blurry, decorated with 3-4 black strokes or dots. The hindwings are gray or brown, and lighter at the base.
- The codling moth is a gray night butterfly, its wingspan reaches 15-20 millimeters. Light pink caterpillar with a brown head. Length – 18 millimeters, and pupae – from 9 to 12 millimeters, yellow-brown.
Also, leafworms are divided into two types – codling moths, which can be called a real problem for agriculture, and loaches. The second species lives mainly on young shoots of conifers. The leafworm reacts not only to fruit trees, the oak leafworm infects entire oak groves, and is considered very dangerous. Fruit and berry crops are also very affected by the leafworm, and for different crops there are different types of it.
What is dangerous?
Insect development in different cultures occurs in different ways. Bud spinner reproduces on horticultural crops, apple, cherry and pear. The caterpillar feeds on buds, then leaves, and then hides in them, rolling up dense lumps. Such lumps turn brown and dry up, and that part of the leaves that is at the top of the young shoot can be damaged.
In order to fully protect your garden from the leafworm, you must fight not only the moth itself, but also the caterpillar.
The wings of a dark gray butterfly are located behind. Caterpillars are brown. Rose leaflet is a cone and spruce butterfly. It develops on many cultures, eats leaves, and rolls them into a bundle or makes a lump out of them. The food area changes several times. The caterpillar also eats the fruits, leaving wounds of various shapes on them. Pest control is carried out by various methods. The currant leafworm reproduces and feeds only on fruit crops. They may be berry bushes or trees. Feeding on the edge of the leaf, the caterpillar after a while makes a bundle out of it. Dealing with such a pest can be difficult. The fruit leafworm at a certain time did quite a lot of harm, and it was also difficult to deal with it.
If we compare it with the hawthorn butterfly, then it has some advantage. It harms different types of fruit crops. Various measures are being taken to combat this pest. However, the prevention of its occurrence should always be carried out, as well as the fight. Apple leaflet – very dangerous for apple and pear trees. A very strong spread can allow it to appear in garden plots, and damage up to 75 percent of the entire crop. If such a butterfly appears, then infected fruits can become infected with another disease – fruit rot. For the fight, the same methods are used as for any other pest. Such codling moths harm horticultural crops quite strongly. Shrubs and fruit trees are also affected. A lot of effort is put into pest control, but completely getting rid of such a butterfly can be difficult.
Control measures
There are several methods for dealing with leafworms. The larvae are able to move from one plant to another, and in case of danger, slip out of the created cocoon. How to get rid of a pest? Every gardener should know this in order to protect the garden from danger and keep it clean. For a full-fledged fight, it is also necessary to carry out preventive work. To save time, you need to use insecticides, because if you start the development of insects, you can wait until a really difficult time comes for your garden. Special types of insecticides are designed specifically to control insects, moths and caterpillars.
Processing of the plant should begin even before it blooms.. It is best to use a not very cool day for processing, the temperature outside should reach up to +10 degrees. If the temperature is lower, the larvae may go under the bark, and the drug may not overtake them. The solution can be used in a ratio of 5 milliliters per 5 liters of water. The amount of water per landing is also determined, and 5 liters of water are used per landing. If caterpillars have appeared on your apple tree, it is best to start using the old proven method, namely, processing leaves that have been infected.
It is very important to prevent the caterpillar from leaving the cocoon it has created, and to hold it so that it does not run away. This method is very convenient because the plant cannot be damaged very much. There are several types of chemicals that can be useful for treating leaves and trees. All chemicals can act on the larvae that hide in the leaves. Some products can be used at a temperature of 22 degrees. In warm air, the drug may be less effective.
It is used when the plant is really in poor condition and damaged. There are also folk remedies for the struggle. In order not to use toxic drugs, you can use household and conventional means, such as tobacco infusion, or a decoction of wormwood. This treatment can be carried out after flowering. Some moth control measures can also be useful. For this, a special infusion is made, which is poured into jars and hung in the crown of trees. In addition to it, bread kvass can be used for prevention.
