Trap Spacing and Placement: To avoid possible interference among lure attractants, do not place traps for European cherry fruit fly and other target pests in the same tree.
Method Notes:
11/28/2016: Traps may also be placed in honeysuckle, another significant host of Rhagoletis cerasi. If the plant is large enough, the trap can be hung from the main stem. If the plant is unable to support the trap, hang it from a metal or wooden stake placed in close proximity to the plant, making sure the trap is level with the crown of the plant.
11/28/2016: In addition to traps, sweep netting is an approved sampling technique for surveys in cherry and honeysuckle. Sweep netting around honeysuckle has been found to be an effective method for detection of adult flies in Canada.
10/03/2016: This trap is a gridded, paper yellow sticky card with a protein bait loaded into the adhesive. Note: this trap does not contain ammonium acetate. A separate ammonium acetate lure is required.
The trap must be the Sticky Card, Yellow, Baited trap available through the PPQ Trap and Lure Ordering Database.

Lure Notes:
12/12/2016: Ammonium carbonate lures have also been shown to be effective for Rhagoletis cerasi. However, in order to standardize data and survey supply procurement, it is preferable that states use the ammonium acetate lures available through the Survey Supply Ordering Database. Negative data may be reported if states conduct trapping for other target fruit flies using ammonium carbonate lures. However, it is imperative that traps must be placed in one of the two Rhagoletis cerasi hosts: cherry or Lonicera (honeysuckle). Negative data may not be reported from trapping conducted in other fruit fly hosts. Ammonium carbonate lures will not be available through the Survey Supply Ordering Database. The length of effectiveness of this lure and dispenser type varies depending on the manufacturer. Consult the manufacturer"s instructions for the lure.
10/03/2016: The Ammonium Acetate Lure in the patch form is no longer being produced. For 2017 surveys, the lure is available in a "polycon" dispenser. If you have patches, you may continue to use them, as long as they are still effective. Please note that the patches are effective for 28 days but the polycons are only effective for 14 days.
Identification
ID/Diagnostic: Morphological
Morphological: R. cerasi can be distinguished from many of the Rhagoletis species present in North America by the combination of its predominantly blackish body and its wing pattern. Rhagoletis cerasi adults can be distinguished from these other species by their wing patterns; the three species of Rhagoletis present in the United States that attack cherries lack the intercalary band and have a forked apical band or an apical spot. There are two species of Rhagoletis in the United States that have intercalary bands, R. basiola and R. meigenii; however, these species do not look very similar to R. cerasi.
Mistaken Identities:
Not present in U.S.: Rhagoletis berberidis
There are three Rhagoletis species found in North America that infest cherries: R. cingulata, R. indifferens, and R. fausta. (black cherry fruit fly) (USDA, 1983).
