Leafhoppers: Generalities




The leafhoppers they are small insects, whose scientific name is Empoasca vitis, very similar to tiny-sized cicadas, or to very small grasshoppers; they preferably infest the vine, but they can also be present on various ornamental species; this insect develops particularly in the summer, the adults prick the leaf page and suck its lymph, causing the decay of the plant, spots on the foliage, with consequent drying, presence of browning on parts of the foliage or thinner stems; often the small insects are clearly visible on the foliage, and they detach themselves when the leaves are shaken.
In addition to the direct damage caused by these insects, the leafhoppers carry some important diseases, including the golden flavescence of the vine, which is the cause of rapid death in vines.
On ornamental plants leafhoppers do not always produce irreparable damage, generally their presence is eradicated with the use of broad-spectrum insecticides. In organic farming, in the garden, the first remedy, to be used in case of infestations of slight entity, is the soft soap, which "washes away" insects and larvae from the foliage, containing the population.
In the vineyards and in intensive cultivation in organic farming, instead of leafhoppers instead they are introduced into the cultivations of antagonist insects. It is essential to intervene promptly, above all to avoid any damage caused by the diseases transmitted by the buzzers.
