Scale insects are considered a formidable pest of all plants because they spread easily and adapt to insecticides. Knowing how to control them will bring the desired results.
Description of the scale insect pest
It belongs to the family of sucking pests—Pseudococcids. It can easily be confused with a scale insect, a distinguishing feature being the presence of a waxy shell that completely encloses the body and can be easily torn off.
They are very active year-round. They are not picky eaters, feeding on both garden and indoor plants, including poisonous ones. Upon detection, immediate control and preventative measures should be taken; otherwise, the scale insects will become established and difficult to remove.
Houseplants most susceptible to scale insect attacks
Many plants are susceptible to pest attacks. Orchids are the most popular. Ficus, ivy, cyperus, palms, tangerines, asparagus, lemons, and rhododendrons are also particularly popular.
Avoids fluffy plants such as violets, eschynanthus, and also Gesneriaceae species.
They can enter your apartment with soil brought from the garden or with the purchase of a new plant. Therefore, it's necessary to inspect not only the flowers themselves but also the soil.
What does a plant affected by scale insects look like?
The presence of scale insects is indicated by the presence of brown spots, followed by the shedding of infected parts. This occurs because the pest sucks out all the plant's vital energy, draining it of its vital energy.
The following distinctive features can be identified:
- the appearance of sticky spots;
- yellowed leaves, as well as stunted flower growth;
- presence of brown tubercles.
Causes of scale insects
The main cause is believed to be purchasing a new plant and introducing it too early into existing plants. To avoid this, carefully inspect the new plant and place it away from other plants for a while. Rinsing the leaves and stems with warm water is a good idea.
Mature specimens typically settle on a single plant and feed on its sap, leaving other flowers alone. Young specimens are very active and easily migrate to neighboring plants.
Various methods of combating scale insects
