What does aphid look like

Black aphid is one of the most common species along with green aphid. It is an insect with a dark-colored body, 1.5 to 2.5 mm long. Has an angular head with antennae located on the forehead. Wings can be present (one pair) or absent (depending on the stage of development). The legs are walking, the front pair is jumping, due to which they easily move along the branches of viburnum and other plants.

Black aphids go through several stages of development:

  1. Egg - the pest hibernates on viburnum and other perennials.
  2. The founder is a wingless larva. Appears in spring from an egg and begins to feed on juices. After breeding, it gives another 50 larvae.
  3. Wingless virgin. These are the larvae that were born from the founder. Give several new generations.
  4. The settler is the stage of the winged generation of aphids.
  5. Normal male and oviparous female - emerge from the larvae of the previous generation and lay eggs again for the winter, after which the cycle repeats.

Black aphid feeds on plant juices, which leads to wilting of the leaves.

Pest colonies are very dangerous, as insects stick to all plants, methodically destroying them. They harm delicate leaves, flowers, ovaries, buds, buds. This leads to a decrease in the yield of viburnum, so you should get rid of the aphids as soon as possible.
