During the ripening of the fruits of the plant, aphids attack, so the main task of gardeners is to intervene in time to protect against these small insects. The deciduous part of the shrub with the presence of aphids is a crust covered with red spots that looks swollen. At black currant green leaves are wrapped in pipes, where hundreds of small insects are located on the inside.

An interesting fact is that the laid eggs overwinter unhindered on open shoots even at low temperatures.

In spring, in places where insects accumulate, the leaves swell and turn red. Young branches are missing nutrients for normal growth, so their development is suspended, and the leaves twist and deteriorate. The same applies to blackcurrant bushes, which are very fond of shoot aphids. The principle of deposition of larvae in these insects is the same as in red gall aphid, only the eggs are black and overwinter at the beginning of the kidneys. After the onset of heat, the larvae move to the upper parts of the kidneys, smoothly moving on to attack young petioles and green leaves.

When spreading, insects move along the shoots, the tops of which must also be removed along with the galls, where the insects settle. To dispose of unwanted plant material, take a bucket of water.

Aphids live on the underside of the leaves, forming rather large colonies, and manifest themselves by the appearance on the leaves of the so-called galls - convex growths of a dark red color. As the leaf ages, the galls may become yellowish or greenish. With a strong defeat, the leaves dry up and die, the growth of shoots is inhibited.

The size of adult aphids is 2.2 - 2.5 mm, the color is from lemon yellow to brown. Eggs laid in autumn overwinter in cracks in the bark near the buds. Hatching of pests begins quite early, during the blooming of the leaves. External signs lesions - galls - appear on the leaves during the formation of ovaries. The greatest number of pests reach in June. The flight of winged females begins in early summer and culminates in July, when aphids move to weeds where they feed until autumn. Then the females return to the currant to lay eggs. Wingless individuals can remain on the currant all season. Over the summer in middle lane several generations of aphids hatch (up to 8).
