| Description: |
| The two insects, above listed, are little coleopters similar between them and both xylophagous. The adults have cylindrical form with dimension between 4 and 7 mm, brown - blackish elytra, pronotom and head more dark. They live exavating tunnels in the wood; their grubs presents a light colour and a bulge in the terminal part of abdomen. Also the grubs are xylophagous the damage is provoked by numerous tunnels, presents in the medullary zone and in vine shoots, excavate at the end of summer. |
| Biology: |
| The two vine coleopters (bark - beetle) winters at the adult stadium inside of little cell excavated in the vine shoots; come out at the first hot (beginning of april) and go in search of run down vine shoots on which lay the eggs. At the end of june- beginning of july are born the grubs that move to the medullary zone. The new adults come out at the end of july-august and excavate tunnels along the vine shoots provoking the damages. The coleopters (bark - beetle) makes only one generation per year. |
| Damage: |
| The fight is agronomic and executes itself removing the plants and the runnig down vegetation or leave in the vine yard, april-may, some residuals of death prouning to favour the oviposition and after, at the end of may, burn all, destroying eggs and young stadium eventually presents. |
