Mealybug – the sucking insect is a close relative of the scale insects. The parasite, 5 mm in size, settles mainly in the recesses of the leaf axils, but can also live around the buds of pedicels or in the orchid flowers themselves. The mealybug larva looks like a light gray fluff, resembling a small piece of cotton wool. The mealybug lays eggs, enveloping them in white threads not only on plants, but also in other places so that the larva can feed on its own.

Damage is caused by vagrant larvae and adults – females, which pierce the leaf film and suck nutrients from the plant. Digestive enzymes secreted by worms enter the leaf during soft tissue bites and negatively affect the metabolism of plants. The infected plant weakens, becomes vulnerable to any other diseases.
