Pest Summary

Before proceeding with the destruction of the insect, you should make sure that it damages the currant fireboxrather than diseases or other insects: spider mites, aphids, moths. Recognize the pest will help the description and photo.

Appearance

From a large family of fireplugs, currants are occupied gooseberry. In addition to bushes of red and black currants, the insect is found on gooseberries, occasionally in raspberries. Distributed in the middle and northern strip.

What does an adult butterfly look like:

  • wingspan varies in the range of 2-3 cm;
  • body length 15 mm;
  • short threadlike antennae;
  • front wings of a nondescript gray color with a brown or dark shade;
  • hind wings of lighter color and bordered by dark fringe;
  • a small head with a slightly convex forehead is covered with scales that form a kind of cone.

On a note! In adult mumps, sexual dimorphism is pronounced. You can distinguish a female by a small ovipositor.

Larvae are 16-foot caterpillars with a length of 8 to 14 mm. In newborns, the color is pale yellow, green, which, as it grows older, acquires saturation and gray shades. The head is black. On the sides you can see blurry annular spots.

Brown pupae 9 mm long with 8 curved spikes on the cremaster.

Development Phases and Reproduction

Fighting the fire on the currant will be much more effective if you know the nuances of the development of the insect. Insects overwinter in the pupal stage in spider web cocoons in the upper soil layers. Years of butterflies coincides with the beginning of the budding of gooseberries and currants.

On a note! The mass departure of moth butterflies is observed in the second decade of May. Activity is shown only in the twilight, evening time.

A week after departure, adults begin mating. On the currant, the moth lays eggs in flowers, occasionally under the lower part of young leaves. The female approaches the process with all responsibility and places the embryos one at a time. In her life she is able to give life to 200 individuals.

After 7-10 days, from tiny white eggs, the size of which does not exceed 0.7 mm, voracious caterpillars appear. They braid young berries with a spider web, penetrate inside and eat out the flesh and seeds. Wrecking of larvae lasts almost a month. Having collected the required amount of nutrients, they go into the soil for pupation. One generation of offspring is possible per year.

On a note! Pupae can be arranged in groups in the soil or singly. But they are always in close proximity to the forage bush.

Signs of defeat and harm

The gardener should be alert for the following symptoms:

  • the appearance of the web on the bushes, a spider web can be braided several berries at once, among which there will be fresh, shrunken, wilted;
  • a hole is visible on the berry, from which a web stretches to nearby fruits;
  • upon careful inspection of the berry, the culprit of the web on the currant is also noticeable - the green caterpillar of the moth;
  • the appearance of dried fruits on the bushes, the color change of the berries.

The harmfulness of gluttonous insects can reach impressive proportions. Crop losses range from 50 to 90%.

Interesting! Blackcurrant larvae damage about 8-10 berries. On bushes with red damage is estimated at 15 berries, and on the gooseberry you can not count from 2 to 6 fruits. And this is only harm from one individual!

Ways to neutralize the pest

How to deal with the ognevka on currants, gooseberries, worries every gardener who is engaged in the cultivation of these useful crops. It is possible to defeat butterflies and their offspring if agricultural, preventive measures, and, if necessary, chemical agents are involved.
How to protect currant bushes from a moth:

  • In late autumn, deep hilling of gooseberry and currant bushes to a height of 10 cm is carried out. After flowering in spring, plants should be re-bent. A high earthen barrier prevents butterflies from flying out of the ground after pupation.
  • For the same purpose, mulch the soil near the bushes by means of peat or compost. The layer of organic components does not allow individuals to get out and significantly reduces their numbers.
  • In the case when the moth is spotted on the currant bushes, damaged clusters, berries are cut and disposed of. You can destroy the pest if you pour boiling water over it.
  • Regular pruning of bushes, thinning out thickets in the berry bushes, fertilizing with fertilizers - such measures contribute not only to the growth and full development of shrubs, but also are a good preventive measure against ognevka and other pests. In a well-lit, blown place insects start much less often than in dense thickets.

Folk recipes

  • Ash is a universal folk remedy for a number of pests. It is used both in dry form and for the preparation of infusions. Processing is carried out during the ripening period of berries. The third part of the 10-liter bucket is filled with wood ash. The remaining volume is filled with water and insisted in a dark place for 2-3 days.
  • Mustard powder is used in the same way. Dry matter is sprayed onto bushes and aisles. The solution is prepared from 50 g of powder and 5 liters of boiling water. Insist not less than 48 hours. Then they are thoroughly stirred and used for processing currant bushes when the berries ripen.
