Pests are divided into two types:

  1. Leafy gall aphid.
  2. Gooseberry fruit aphid.

Danger of pests

It is important to do this as early as possible, since insects are able to multiply at lightning speed and quickly harm the shrub. How does this happen?

Each aphid is equipped with a mouth proboscis, which pierces young greens or tender shoots in order to suck out the sap of the bushes. This happens throughout the warm season, from spring to autumn.

When there is not enough food, the aphids form wings, and they fly from the currant bush to the nearby weeds. However, in the fall, the malicious family will still return to “ father's house”To start laying eggs. At this time, males appear, which fertilize females for further procreation.

Sucking vital juices from the stems, the pest colony oppresses the shrub so that it is not able to develop normally. Currant leaves begin to deform, the plant withers and dries up, ceases to bear fruit and eventually dies.

Signs of pests

First of all, it is necessary to regularly and carefully inspect currant bushes: aphids always hide on the inner (lower) side of the leaves.

What other signs should you look out for before starting a rescue operation? Here are some of them:

  • the growth of seedlings has stopped for no reason;
  • branches are bent and deformed;
  • the shape of the leaves curls and distorts;
