Aphids, moths and mites are among the most well-known pests that threaten the ornamental and vegetable beds in our gardens, as well as the harvests of fruit trees and shrubs. We advise you on how to recognize the signs of an infestation by these pests and how to protect yourself effectively against them.
The most well-known pest is aphids.
Aphids are probably one of the most well-known pests, as these insects are harmful to almost all cultivated plants. They are small insects, measuring 2 to 6 mm, with a complex development cycle.
After fertilization, the female lays eggs in the autumn, which overwinter and hatch into winged females in the spring. They then fly over the vegetation and reproduce parthenogenetically (asexually). The unfertilized eggs then hatch into larvae, which then develop into wingless adults. Aphids are also widespread among aphids, so colonies can multiply very quickly. Most generations are wingless, only a few become winged, for example when searching for new plants.
Aphids are damaged by sucking large amounts of liquid, and plants react by twisting, curling or even changing the color of the damaged areas. Some species cause galls. The damaged areas are also covered with honeydew secreted by aphids. Honey is an important part of the diet of ants, which in return provide aphids with protection from predatory insects and parasites. Aphids are also important vectors of certain viral diseases, such as those affecting potatoes, cucumbers or ornamental plants.
protection against aphids
