Aphids: description and types

Both in greenhouses and in the open field, aphids on peppers multiply very quickly. Its colonies cause significant damage to plants, they can even cause their death.

The pest is widespread, it migrates easily. Pepper can affect several of its varieties at once.

Why aphids are dangerous

In addition to the fact that aphids suck juices from young leaves and shoots, it carries many diseases. Even if the pest has not infected the plantings, it produces sweet honeydew, which contaminates the leaves and promotes the development of fungi.

Even the saliva of aphids is dangerous for peppers, it contains substances that are toxic to plants, in addition, it contains viruses that can cause rapidly spreading ailments.

Where does aphid come from

Aphids overwinter in soil or fallen leaves. The eggs of the pest can also be stored in the bark of trees or shrubs. The awakening of adults who survived the winter occurs with the onset of warm days.

Ants contribute to the spread of the pest. They transfer aphids from one bush to another, protect it, because The favorite food of ants is honeydew, a sticky sweet liquid secreted by parasites.

Signs of aphids on pepper

The appearance of ants on the beds should be an alarming signal for the vegetable grower. Aphids should be found on the back of the sheets; upon close inspection, insect eggs can also be seen there.

Further, whitish spots form on the leaves, sticky traces of the honeydew appear, the growth of the plant slows down, and the leaves begin to fade and dry. Pepper flowers crumble without giving an ovary. Deformation of young shoots can be observed. The yield is significantly reduced. Infection of young bushes can lead to their death.

Aphid reproduction is activated with an increase in air temperature; during the summer, one female can reproduce 10 new generations.

Lack of struggle will lead to the fact that the population of insects in the beds will be in the thousands.

Greenhouse conditions are especially favorable for the life and reproduction of the pest, therefore vegetable growers should be especially attentive to the condition of the peppers. When the first signs of damage are found, measures should be taken to eliminate pests immediately.
