The struggle with winter pests in the bark of trees

Wintering in fruit trees - what they are and how to fight
Winter trees are spent in deep sleep.
In the same state are their eternal companions - pests.
Since the summer or autumn, they have been "troubled" about their rest, following the instinct of procreation, adult insects. They have attached them in cracks of a bark, under fallen or specially attached to branches leaves, on the dried (mummified) and left to winter fruits.
February is not the best time to get rid of wintering nests, which are potential eaters of leaves, shoots, flowers, ovaries and fruits.
Against the background of bare branches their nests, oviposition and other adaptations are particularly well visible. The destruction of the nests is now convenient because the land has not thawed by this time, and the snow cover is small and the garden can move freely.
To make it easier for you to orient yourself in the variety of winter nests of pest of fruit trees, we give their drawings, a brief description and methods of processing the nest sites with chemical preparations.

HARVEST
In late July, small white cocoons are woven into damaged leaves of the caterpillar, in which they winter. Such leaves attached to the branches by caterpillars do not fall during the winter. These are winter nests, and in each there are up to 40 caterpillars. When the buds open, the caterpillars crawl out of their nests, damage the kidneys, and then the leaves. Wintering nests must be removed during the winter using the simplest devices. The collected nests are burned.
RED FRUIT TILES
Eggs on fruit branches are very small, orange. With a large cluster, they can be detected. On young trees, eggs are killed in winter, gently scrubbing with a coarse cloth. In adult tall trees, from mites, eggs can be disposed of only in the spring by treatment with the same drugs listed in the description of the means of combating the apple-tree ermine moth.
ZLATUGUZKA
Caterpillars hatch in late July - early August, live in whole broods and eat leaves, leaving only veins. The damaged part of the branch with the leaves of the caterpillar is entwined with a dense white web, forming large, so-called winter nests in which they winter. Nests must be removed and burned.
THE YABLON MINING MOLE
Caterpillars of the second age of this pest in the period of flowering of apple trees form large cobweb nests-colonies.
Damage is so severe that sometimes the trees stand with brown, as if burnt leaves. Winter pest nests are subtle caterpillars of the first age
- are under the egg shields
- small furry formations of a yellowish-brown color on the branches of an apple tree.
The nests are very small and unsightly, and yet try to identify them and clean them with a metal brush or a rough cloth in the set dishes or on a covered film. Cleaning should be burned.
And yet the main struggle will have to be postponed until the spring and before the buds are dissolved, treat the trees with ZOV (600 g per 10 L of water).
Along with the application for early spring treatment of the drug ZOV, good results are also obtained using the DNOC pesticide. In Ukraine, it does not apply to those allowed for use on household plots. But in Russia there is no ban on it. In our markets and in a network of specialized stores, it is sold. With careful application, in compliance with safety rules, it is not at all more dangerous than other authorized drugs. Apply it in a concentration of 0,4-1% (40-100 g for 10 L of water). But it's necessary early, before the buds are blooming.
GREEN APPLE APPLES
Everyone knows the colossal damage that trees inflict on trees in the summer. And the wrecker winters on the thin branches of the apple tree in the form of dark green elongated eggs, which during the winter turn black and shiny. They can be detected only on young, low trees and destroyed by wiping the branches with a coarse cloth. In spring, get rid of the eggs, and then the larvae can be sprayed with the drug ZOV (400 g per 20 L of water).
Rozannaya LISTOVERTKA
It damages many fruit trees - apple, pear, currants, cherries. Eggs hibernate, which the female lays, tiling in groups, but looks like a single smooth shield. Such oviposites (shields) first have a pale green color, but then acquire a brownish-gray hue, reminiscent of the color of the bark of an apple tree. It is difficult to notice them, but they are usually located on thick branches and tree trunks. They are destroyed mainly by treatment in the early spring with the Call of Preparation (500 g per 10 l of water).
WHEEL SILK PROPERTY
Call it a ringed coconut. Butterfly lays eggs with silvery rings on thin branches.
Branches with oviposition are cut off with a crown pruner and burned.
The Noble Medlion (The Apple Leaf)
It damages the kidneys, rosettes of flowers and leaves. Damaged flowers are lost, which reduces the yield. At the end of summer the female lays on the branches yellow, very small oblong eggs. Eggs are deposited on young branches, and they can be destroyed by cleaning with a coarse cloth. But it is most reliable to treat the trees before blossoming of the kidneys before dissolving the kidneys with ZOV preparation (200 g per 10 L of water).
APPLICATION BLADE SHIELDING SHIELD
A small insect that gets its name for the shape of the shield that covers the body of the female. Scutellum brown or brown, painted in the color of the bark of the tree on which the scutellum parasitizes. The length of the shield is 3-4 mm. Under the flap is a pear-shaped female of milky white color.
The pest causes great damage to the tree, sucking the juice out of it, and can lead to its death. Hibernate eggs under the scutes. The bulk of the pest can be destroyed in the winter, cleaning trunks and branches with pest shields. Cleaning should be carefully collected and burned. In the early spring, treat the trees with 308 Preparation (400 g for 10 L of water).
MUMIFIFIED FRUITS
In the dried fruit, which firmly hold on the branches, winter spores of fruit rot, scab and many other diseases. Fruits are removed and burned.
CALIFORNIA SHIELD
The most dangerous quarantine pest that damages about 150 species of fruit, ornamental and forest plants. In the gardens, the biggest harm is caused by apple, pear, plum, cherry plum, cherry and apricot. I had to see the trees of plum trees, which, from damage to the California shield, died during the summer, and by the autumn the leaves dried up, crumbled, the wood was becoming lifeless.
Winter larvae of the first age under a dense shield dark gray or black. During the winter, it is necessary to clean the trees from the shields of this dangerous quarantine pest. Shields are cleaned with hard brushes, by laying a pre-subtree film or tarpaulin. Cleanse thoroughly and burn.
In the spring, before bud budding, treat the trees with ZOOM of high concentration (600 g per 10 L of water).

KRASNO-GULL (SILVER) APPLICATIONS
Many people remember the summer picture of the condition of the leaves of the apple tree, wrapped inwards with a characteristic cherry red or pink coloration. This is damage to red-head aphids. It hibernates the pest in the form of brilliant eggs of dark blue color under the dead scales of trunks and thick branches of an apple tree. Most adult trees are damaged, and therefore it is unlikely that they will be able to get rid of the wintering forms of the pest. Destroy oviposition can be sprayed early in the spring with ZOV.

Leaflets do not have a place in the garden
The leaf rollers are multifaceted - not only fruit trees like them, but also forest, ornamental shrubs. Caterpillars live in folded leaves - hence the name of insects. The most dangerous for garden plants - rosannaya and variegated leaf rollers. Hibernate eggs on the bark of boles and branches. Caterpillars appear at the beginning of flowering plum, cherry. They gnaw on buds, buds, leaving only "skeletons" from young leaves. After settling among the inflorescences and ovaries, the growing caterpillars tighten their webs.
On the ovaries and fruits gnaw grooves, reaching sometimes pits. As a result, the damaged fruits fall off or, while continuing to grow, become ugly, which we have observed on our site more than once.
How to deal with pests?
In autumn or winter (in the second half of February) we carefully clean the trunks from the old bark, we update the whitewash.
In the spring, before budding buds, we treat plants with insecticides. Re-treatment is needed when the caterpillars emerge from eggs: for apple and pear - before flowering, for stone (cherry, cherry, plum, plum) - immediately after it. If sprayed later, there will be almost no effect, since the caterpillars already hide in the swirling leaves, and thus are protected from the full impact of "chemistry".

How to defeat a tortilless
The bunching leaf is a dangerous grape pest. Outwardly, it is a small butterfly, its wingspan is slightly more than 1 cm, the caterpillars are also small - up to 2 cm. The insect lays eggs in the cracks of the vine bark, under fallen leaves, in wooden props. Larvae hibernate at the stage of pupae in cocoons; in spring they turn into butterflies, which again lay eggs. The caterpillars emerging from them begin their destructive activity: they entangle inflorescences with a cobweb, eat flowers and ovaries. Each caterpillar can destroy: up to 30 buds! Caterpillars of the summer generation destroy berries - each can eat up to 10 berries.
To prevent this, during the massive summer of butterflies and the release of caterpillars, in a dry weather, treat the plantation with insecticides. Fortunately their choice in the market is now big.

The shield is a small but very dangerous pest of indoor and garden plants. It is very easy to recognize by the wax shell that covers the body of the insect.
The plants affected by the scabbard become sticky. On the leaves appear yellowish spots. It is interesting that most often the scutellum affects palms, cacti, chlorophytum, sheffler (or sheffler), some ivy, citrus, oleander, dracen, ficus and fat.
Often a pest enters our homes through open windows. Therefore, it is better to put a fine mesh immediately. Also, scabbards can fall into the premises with donated bouquets. While flowers please us in a vase, insects manage to spread around the house. Another loophole may become contaminated soil, so it is important to monitor its quality and plant plants in the decontaminated soil.
If the infection does occur, the affected plant must first be isolated from the healthy and placed in a bright cool place. Sill wipe with alcohol solution.
With mild lesions it will be enough to wash the plant several times with a solution of laundry soap. In later stages, it will be necessary to periodically clean the leaves of the pest and treat the plant with preparations. Remove the scabbard can be a soft brush, soaped with laundry soap, or cotton swabs, soaked in alcohol. When processing chemicals, plants should be taken to places where there are no people, to wear a mask and gloves.
