Mealybug: what is dangerous and how to fight

Mealybug - an insect that can live only with the help of another living organism. Parasitizing on one victim, the scarlet immediately finds the next. It was once used to produce red paint, but now it is known as the largest parasite in scale.

What does the parasite look like

Science knows more than 2,200 species of mealybug family. On its oval body, it has a white wax, resembling flour from afar. That is why this name is given. Males of the family are usually larger than females. The average size of a mealybug is up to 6-8 mm (like a larva of a ladybug). Although its size is small, it can be found in the early stages of plant disease.

Important! This insect can breed on greenhouse plants (tomatoes, cucumbers, etc.)

What is dangerous and where does it come from

A mealybug is comparable to a time bomb for flowers. It is dangerous because the plant is easily infected and quickly dies. The latter is due to the fact that the insect simply sucks the juice. The pest can be located both in the root system and in the leaf axils. Let us examine in more detail where the mealybug is taken.
