Aphids on currants: characteristics of the pest
It is not difficult to see signs of a pest on currants. There are a very large number of species of this pest. So, for example, if bubbles and dark bulges appear on the leaves or on the branches of a red or white currant bush, it means that leaf aphids have settled here. This is only one of 4 thousand species of the aphid family.

Aphids on currants: insect damage
In addition to the above-described harm, the parasites make the plant very weak, unable to fight various diseases, which begin to actively spread over the area where a lot of this pest has bred. Allocating a sticky mass, aphids leave it on the stems and branches of currants, which is why the air does not pass through the bark well. In addition, pathogenic fungi and bacteria actively multiply in this sweet substance. After the aphid has divorced on the bush, the currant gets sick from sooty dew.
Ants, which, it would seem, help us get rid of the insect pest, on the contrary, contribute to an even stronger spread of aphids around the site, as they help the pests move, transporting them to different places where they continue to actively reproduce. Ants do not leave aphids alone, because, as lovers of sweets, they also love this very honeydew.
