General information about the pest

Aphids belong to the insect superfamily, the order of beetles. More than three thousand species are known, some of which inhabit Europe. Size ranges from 2 to 7 mm. The insect has a proboscis, which pierces a leaf or a plant. It feeds on vegetable sap, releasing a sweet liquid - a drop, which attracts ants and other insects. In all species there are winged and wingless individuals.

The pest appears in spring from the larvae hatched from eggs laid on the host plant in the fall. After molting, the larvae, feeding on the sap of young shoots, begin to multiply, producing wingless females.

These insects in one month can reproduce three generations, numbering more than a hundred thousand individuals. When the stems of young plants become rigid, the winged aphid appears, which flies to another place and the reproduction process repeats again.
