Fruit striped moth from year to year feasts on cherries and cherries, as well as juicy apricots and fleshy plums. Nevertheless, in addition to stone fruit crops, it sometimes damages apple trees. Entering the fruit, the gluttonous caterpillars of pests begin to actively eat up the pulp, reaching the very bones. The result of such attacks is the manifestation of gum flow on the damaged areas (most often near the peduncles)
Meet the pest
The striped fruit moth is a small brownish-grayish moth, whose wingspan reaches a maximum of 14-16 mm.
Endowed with black heads and growing up to 12 mm in length, brownish caterpillars of pests overwinter mainly under the bark of young twigs, gnawing into it mainly in branched areas. You can notice such areas with the naked eye - they are given out by the dust-like accumulations of caterpillar excrement.
In the spring, as soon as tiny buds begin to bloom, harmful caterpillars gradually leave their wintering places and instantly bite first into the buds, and a little later into the middle of young shoots, which dry out rather quickly. After that, the gluttonous parasites move to other shoots, which later also die. A single caterpillar can easily destroy up to five shoots. Then the well-fed pests leave the damaged shoots and pupate, comfortably settling in the cracks of the bark.
In June, one can observe the appearance of the first generation of butterflies. In the daytime, they always hide, and with the onset of dusk, the females fly out to lay eggs. Eggs are laid by them on the shoot bark, as well as on fruits with leaves. And after about two weeks, hungry caterpillars hatch, immediately biting into the shoots with buds, which in turn leads to their early death. As soon as the caterpillars finish their feeding, they leave the previously attacked fruits with leaves and go in search of places for pupation. And closer to the end of summer, one can observe the appearance of harmful butterflies of the second generation. These butterflies also lay eggs, and the caterpillars hatched from them feed on the pliable shoot bark until autumn, making passages there in which they will winter.
On shoots and fruits attacked by harmful parasites, numerous influxes appear, from which gum subsequently begins to flow out with small inclusions of caterpillar excrement. Fruits hopelessly spoiled by pests fall off prematurely and rot almost immediately, which leads to a significant decrease in the volume of the crop and its quality.
How to fight
With the onset of early spring, they begin to spray fruit trees with yellow oil, and before the tiny buds bloom, it will not hurt to treat them with Nitrafen (3%).
Treatments with Chlorophos, Karbofos or Zolone give a good effect during bud break. In the summer, treatments with "Typhos" (0.1%) or "Metathion" (0.15%) help to cope with pests. If the trees are very badly damaged, then it is recommended to repeat the treatment after a couple of weeks.
At a temperature of more than twenty degrees, a biological product called "Entobacterin" (0.5%) can be used against pests. Some summer residents actively use hunting belts to catch gluttonous parasites, applying them not only to the trunks, but also to the main branches.
Shoots damaged by fruit striped moths must be promptly cut out of the crowns and burned as soon as possible. The carrion also needs to be collected and destroyed. Additional loosening of the soil under the tree crowns will not be superfluous.

It seems to many that insurance of houses and other items is a modern innovation of the 20th century. In the old days, they didn't do that kind of thing.

Gypsy Moth - A Thunderstorm Of Fruit Trees
Unpaired silkworms harm about three hundred species of vegetation. However, most often these parasites can be found on fruit trees, as well as on poplars with oaks. In the case of mass reproduction, harmful caterpillars entirely eat up leaves on solid territories, which almost always leads to drying out of trees. Therefore, it is extremely important to timely identify the appearance of intruders and take appropriate measures against them
Sly Top-sided Fruit Moth
The top-sided fruit moth is a small, but at the same time, very harmful insect. It causes irreparable harm to fruit crops and contributes to a noticeable reduction in harvest volumes. These pests are especially fond of the leaves of apple trees. Fruit trees are mainly harmed by caterpillars, actively making numerous mines in the leaves. If in time to identify the appearance of these enemies on the site and immediately take appropriate measures against them, the coveted harvest will be saved
Inconspicuous Striped Seed Nutcracker
The striped seed beetle is polyphagous and can damage very different crops. Its main habitat is forest-steppe and woodland. The larvae of the striped sowing nutcracker willingly eat young roots of cereals, and also damage root crops, stems, tillering nodes and sown seeds. The damage caused by the larvae of two and three years of age is especially noticeable. Adults of this variety of clickers are less harmful. Males are generally completely harmless, and females, although they
