Juicy and sweet grapes like not only people. They do not mind eating wasps. They gnaw through the skin of the fetus without much difficulty, reaching the delicate pulp. And although they are not able to eat the whole crop, the berries that they “tried” rot, they as a result, the whole brush is affected by bacteria and fungus. Damage, thus, increases at times.
