How to protect yourself from pepper pests in a greenhouse

When growing peppers in a greenhouse, the gardener is faced with a lot of unpleasant surprises. The most dangerous are pests. Insects spoil fruits, root system, leaves, stems. We will consider the description and photo of pepper pests in the greenhouse and their treatment in the article.

Causes and signs of pests on pepper

How to protect yourself from pepper pests in a greenhouse

The main reasons for the appearance of insects on pepper are as follows:

  1. Flight from other cultures. For example, aphids are thrown from tomato, cucumbers... Pests attack both greenhouse plants and those growing in the open field.
  2. Contaminated soil... Often, beginners ignore pre-sowing decontamination work or transfer the land with insect larvae from an open area.
  3. Failure to comply with agrotechnical rules. Improper watering and feeding, as well as untimely work on the destruction of larvae lead to active reproduction of pests.
  4. Unfavorable climatic conditions... Some insects are attracted by heat, others by too wet soil. If you pour the peppers and do not air the greenhouse in time, the conditions will be favorable for the early development of diseases due to the influence of pests.
  5. Dense plantings. Sunlight does not penetrate between plants. The soil does not warm up and insects appear.

The signs of pests are as follows:

  • weakened stem;
  • pepper withers quickly;
  • late blight, gray rot and bacteriosis appear.

In advanced cases, the diseased plant dies. Insects, along with infection, continue to infect neighboring peppers and other greenhouse crops.

What harm do they do to the plant

How to protect yourself from pepper pests in a greenhouse

Insects suck juice from stems and leaves, devour roots and fruits. Most often, the larvae of adults cause the death of plants. Their secretions and waste products provoke the appearance of infections. This is late blight, gray rot and bacteriosis. They, in turn, destroy groups of plantations.

What are the pests of pepper in the greenhouse

Insects attack pepper even if all agricultural rules are followed. Therefore, at the first sign of their appearance, they immediately begin a struggle to save the pepper and neighboring crops.

Naked slugs

How to protect yourself from pepper pests in a greenhouse

Molluscs without a shell look quite harmless. However, they are able to destroy not only peppers, but also cabbage, beets, and cucumbers. More often, adults attack young bushes.

Signs of appearance:

  • rounded holes on the leaves;
  • slimy traces;
  • rotting pepper;
  • excrement on the stem and leaf plate.

In the daytime, naked slugs hide under the ground, vegetation, boards, stones. A comfortable environment for them is thickened plantings, high humidity. But mollusks die in extreme heat, and are activated only during prolonged rains.


This insect spoils the green mass of the bush and fruits. The scutellum has a rounded body about 2 mm in diameter. The body is covered with a protective brown shield, so the pest is not visible.

The danger is the larvae. They quickly penetrate the leaf plate, sucking the juice out of it. At the same time, the surface of the plant is covered with round dark plaques, a sticky bloom.

Reference. Female scale insects live in a sticky plaque that larvae continuously excrete. They move into a stationary lifestyle, constantly feeding on the plant.

This pest is not easy to find in a greenhouse, but traces of larvae in the form of twisted pepper leaves are noticeable.

Whitish butterflies lay eggs on the underside of the leaf plate. Then voracious larvae appear and begin to actively suck the juice from the plant.


  • twisted leaves;
  • sticky honeydew;
  • death of bushes.

Isolation of whitefly larvae is a favorable environment for the reproduction of pathogenic fungi. In advanced cases, pepper dies from bacteriosis.

  • groups of green insects in individual areas of the pepper;
  • transparent sticky coating on the leaves;
  • ants;
  • eaten edges of leaf plates;
  • yellow, twisted leaves;
  • cessation of the development of the bush, twisted tops;
  • dried inflorescences and deformation of the fruit.

Ants do significant harm to the pepper, but they leave the greenhouse on their own when the aphid is completely killed.

Spider mite

  • web;
  • holes in the leaves;
  • death of inflorescences and ovaries;
