Survey Information

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.

The 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.
