Beautiful blooming orchids are the pride of any housewife. However, non-observance of the rules of care, inappropriate conditions for life and growth can provoke various diseases.

And on weakened plants, pests quickly appear that destroy it in a few weeks.

How to deal with such attacks? What pests most often attack phalaenopsis? This is discussed in this article.

What parasites infect these flowers?

Reference. Most often, pests look like small bugs, mostly white.

Their accumulation is large, therefore, it is difficult not to notice them. Most often, the orchid is attacked by:

  • aphid;
  • spider mite;
  • thrips;
  • worm.

As a result of their effect on the leaves, stems and flowers, lesions are formed, which are characterized by a brown color, dry to the touch, and sometimes, there are completely ruptures in the plant tissue.

What is the danger?

As a result of exposure to pests, plants stop growing, the process of providing moisture and nutrients slows down, in the end, the phalaenopsis dies.

At the initial stages of infection, the leaves begin to lose moisture and turn yellow rapidly, gradually curling.

If you run your hand over the surface of the sheet, you will find that it is completely covered with a slimy substance. On the stem, strange bumps, punctures, and affected areas begin to appear, so it is likely that the stem may simply break off.

All these listed phenomena indicate that plants are exposed to pests.

Which parts of the plant are affected?

As we have already found out, insects begin to appear from the very roots, most likely, they initially choose a substrate for life. It is there that they multiply, get stronger, and then rise up.

Therefore, the phalaenopsis root system is initially affected. Namely, thanks to the roots, the plant can feed and receive nutrients from feed and liquid. The affected roots cannot absorb moisture in the proper amount, so the plants begin to turn yellow rapidly.

Important! Insects begin to climb the roots, after which leaves meet them on the way. Therefore, the leaves closest to the substrate are affected first.

They turn yellow, lifeless, bite marks and dark spots appear on them.

Only then the insects climb the stem and go to the flowers. As a rule, this is already the last stage of the development of the disease, followed by the death of the plant.

How to check a flower for harmful insects?

Unfortunately, many neglect such a simple procedure, as a result of which, they endanger not only the orchid, but also other flowers at home.

The check is quite simple.

  1. To do this, you need to get the plant out of the protective plastic bag.
  2. Inspection begins with the roots, which are probably clearly visible through the plastic container. See that they are intact, without rotting, as well as dried rhizomes.
  3. In this case, the substrate should be homogeneous, without traces of any insects.
  4. Pay attention to the leaves. They should be healthy, fleshy, bright or dark green in color, with no signs of lack of moisture.
  5. Gently run your hand over the stem. It should be smooth, without thinning, as well as incomprehensible bumps in its structure.
  6. Flowers should be bright, firm, tight-fitting.

Attention! After the visual inspection is complete, sprinkle the orchid well with water. If there are insects, then they will probably drain from the drainage system of the pot along with the water. Pests can be easily spotted in clean liquid.
