There are many beetles of the vine, some of these cause very serious damage, and their control must be carried out with determination and rapidity, to avoid that the plants suffer excessively and bring to maturity a poor and low quality crop. Other pests, on the other hand, tend not to produce excessively numerous generations, and their damage is almost exclusively "aesthetic", which does not affect the productivity of the entire plant.
The fight against many of these insects is difficult, because the body repaired by a rigid armor is unlikely to be damaged by the most common insecticides, unless it is possible to directly strike the insects with the chosen product. Since most of these insects have a mainly nocturnal activity, it is very difficult to practice truly effective treatments. Often the fight takes place against the larvae or the eggs, or with particular cultivation care.
The most harmful beetles
Among the most harmful insects of this type we can mention the oziorrinco, which indiscriminately attacks fruit and ornamental plants: the larvae are present in the soil, and devour the root system; the adults have mainly nocturnal action, and from the ground they climb on the plants, mainly consuming the shoots and the young leaves. The bark beetle of life is an insect that digs tunnels in the branches: the females lay the grapes in circular tunnels, dug in the nodes of the twigs, especially in dry wood or in decay. The adults feed on the shoots in the spring, and dig tunnels in the wood for winter shelter.
The scribe adults feed on buds and buds, which dry out; the larvae eat the roots. The rhizotropic larvae of the vine eat the thinnest and most delicate roots. Clearly only large populations cause damage to plants; the presence of some specimens is completely harmless in a vineyard, but must be checked to prevent a single adult from laying many eggs.
