Phases of ognevka development on currants
The start of the departure of the butterfly depends on the weather and average daily
air temperatures. It usually coincides with the budding phase and
the beginning of flowering of early varieties of currants.
Five to seven days after the departure of the moth, they lay eggs in
flowers One female can lay up to two hundred eggs. Years of butterflies
lasts two to three weeks. Eggs from ognevka are white, oval, in size
about 0.75 mm. The main butterfly clutch is produced inside the flowers. AT
In egg, the future moth develops in about one week.
Newborn caterpillars whitish-yellowish, from two to three long
millimeters, with a black head.

moths are located in 5-7 pieces in the upper layer or on the surface
land under garbage, fallen leaves, clods of soil within a radius of
more than forty centimeters from the bush.

Methods of protection against ogniyevka on currants and gooseberries
Chemical and biological preparations
The protection of the currant from the fire is based on chemical and
biological preparations.
Chemical control of ognevka on currants is
spraying bushes before flowering and after. After
flowering usually use the following chemical
drugs:
• Actellic (0.2%),
• Kinmiks (0.05%),
• Spark M (0.1%).
• Fufanon (0.2%).
AT скобках указано процентное содержание (концентрация)
insecticide in the working solution.
Also used karbofos, kilzar, rovikurt.
The waiting period for all these insecticides is the same and equal
twenty days.
AT теплые годы с дружной весной обязательно опрыскивание
currants and gooseberries before flowering. It drastically reduces
the number of caterpillars and their damaging berries. AT эту
fenofazu currant development is desirable to use
drugs:
Kinmiks (0.05%);
Spark M (0.1%).
Great effect have the treatment of plants during periods of transition
caterpillars from one berry to another. But the “chemistry” on sauteed berries
can not be used because it threatens the environmental safety
harvest. Можно применять биоdrugs:
• Fitoverm (0.3%),
• Bitoxibacillin (1%),
• Lepidocide (0.3%), which is effective only against caterpillars

Waiting times
• Fitoverma – 2 days,
• Lepidocide – 5 days.
Of the biological preparations, Agravertine and Iskra-bio are also used.
Treatments against gooseberry moth combined with spraying
currants from other pests and diseases.
Agrotechnical techniques
Since the pupae of the gooseberry ognevka overwinter in the ground, fighting with
The following measures will help with wintering cocoons:
• Digging and hilling currant bushes in late autumn. ATысота
hilling – up to ten centimeters. From under the ground more than 5-7 cm
butterflies can not escape.
• Spread currants after flowering.
• Mulching the soil around bushes with compost or peat in front of
flowering. The layer of mulch under the bush makes it difficult for butterflies to come out,
and, thus, the number of this pest is reduced. Soil
can be covered with foil, paper, mulch paper. Clean cover after
flowering berries.
• Manually collecting and recycling damaged berries along with caterpillars
moths located in them.
