The European cherry fruit fly (Rhagoletis cerasi L.) is the most serious pest of cherries. 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 through the transport of infested fresh cherries, soil, or fruit from host plants grown in areas where this pest is found. In 2016, Canada confirmed this pest on wild honeysuckle at several sites in Ontario. In 2017, the APHIS found European cherry fruit fly on traps hung in wild honeysuckle plants and sweet cherry trees along the Niagara River in New York. This was the first U.S. detection of European cherry fruit fly.
If European cherry fruit fly becomes established in the New York and spreads to other parts of the country, it could threaten commercial cherry production along the Pacific Coast (California, Oregon and Washington), and in the Northeast (Maryland, New York and Pennsylvania), and in several Western and Central States (Colorado, Michigan, New Mexico and Utah), and affect U.S. cherry production.
