The European Cherry Fruit Fly (Rhagoletis cerasi) is a pest of Prunus spp. and lays its eggs in ripening cherry fruit. Surveys are conducted because of the presence of potential host material in Wyoming. It has not been found in the US. To date, it has not been found in Wyoming. Fifty-nine total traps have been placed throughout twenty-three counties in Wyoming.
Wyoming European Cherry Fruit Fly Survey is conducted by the Wyoming Pest
Detection / CAPS Program. A sticky trap with an attractant is placed on or near
the host plant from May until August. The traps are monitored for suspects and
serviced once a month. If suspects are found they are sent to the University of
Wyoming for further identification.
