European cherry fruit fly – Rhagoletis cerasi
The European cherry fruit fly (Rhagoletis cerasi L.) is the most serious pest of cherries in Europe. Damage associated with this pest is caused by larval feeding in the fruit pulp, which can result in losses of up to 100% if left uncontrolled. This pest may be introduced to new areas with fresh cherries or with soil or fruit from host plants grown in areas where this pest occurs.
