“…6A and B). Variable responses by R. pomonella to fruit volatile odors from lures within and across Þeld studies are common (e.g., Reissig et al 1982Reissig et al , 1985AliNiazee et al 1987;Jones and Davis 1989;Reynolds and Prokopy 1997;Stelinski and Liburd 2002) and could be affected by many factors, including the physiological state of ßies (age and hunger) and the environment (fruit loads and ripeness, competing odors, temperature, precipitation or humidity, and wind currents). Also, the blends may not show the speciÞcity in mixed-tree settings such as Skamania that they do in single tree settings because of ßy movement among different trees.…”

The apple maggot fly, Rhagoletis pomonella (Walsh), is an introduced, quarantine pest of apple (Malus domestica Borkhausen) in the Pacific Northwest of the United States. In the eastern United States where the fly is native, fruit volatiles have been reported to be more attractive than ammonia compounds to R. pomonella. However, the opposite may be true in the western United States. Here, we determined whether newly identified western apple and western hawthorn fruit volatiles are more attractive than ammonium carbonate (AC) to R. pomonella in apple, black hawthorn, and ornamental hawthorn trees in western Washington State. In all three host trees, sticky red sphere or yellow panel traps baited with AC generally caught more flies than traps baited with lures containing the four newly developed fruit blends (modified eastern apple, western apple, western ornamental hawthorn, and western black hawthorn) or two older blends (eastern apple and eastern downy hawthorn). Fruit volatiles also displayed more variation among trapping studies conducted at different sites, in different host trees, and across years than AC. The results imply that traps baited with AC represent the best approach to monitoring R. pomonella in Washington State.

“…Besides fruit odor, components of the odor of food also are attractive to R. pomonella (HODSON 1943(HODSON , 1948NEILSON 1960). The major food-type attractant, ammonia, has been used primarily in combination with sticky yellow rectangle traps to monitor presence of R. pornonella in and nearby orchards, particularly in western North American and eastern Canada (PKOKOPY 1968(PKOKOPY , 1975REISSIG 1974REISSIG , 1975ALINIAZEE et al 1987;JONES and DAVIS 1989;WARNER and SMITH 1989). Sticky yellow rectangles are considered to be visual mimics of foliage (PKOKOPY 1968).…”

The influence of odor and visual stimuli on the effectiveness of sticky red spheres in capturing Rhagoletis pomonella (Walsh) flies in a commercial orchard unsprayed after June was investigated.Unbaited 8-cm red spheres (presently recommended size) captured significantly more female and male R. pornonella flies than unbaited 10-cm red spheres. Sticky 8-cm red spheres baited with 1, 2, or 4 2dram polyethylene vials containing 2.5 ml butyl hexanoate at a distance of 15, 30, or 60 cm from the sphere captured significantly more female and male R. ornonellu than unbaited spheres. Spheres baited with 2 or 4 vials of butyl hexanoate, however, l d not significantly increase R. pornonella captures compared with spheres baited with 1 vial. The distance of 1, 2 or 4 butyl hexanoate vials within a range of 15-60 cm around a sphere had no significant effect on R. pornonellu captures. A combination of 1 capped 2-dram vial (with a single 3-mm opening) containing ca. 5 g ammonium carbonate and 1 vial of butyl hexanoate, as lures, increased female and male R. pornonella captures over unbaited spheres significantly more than either 2 vials of ammonium carbonate alone or 2 capped vials of butyl hexanoate, between which there was no significant difference. A protective conical roof partially obscuring a sphere, regardless of colour, significantly reduced R. pornonella captures. The relevance of these findings to potential improvement in use of baited spheres for R. pornonella control in commercial orchards is discussed.

“…A pressing need exists to develop better diagnostic markers to more efÞciently distinguish R. pomonella from R. zephyria, even though morphological methods are also available (Yee et al 2011). This development would improve current monitoring efforts in Washington based on adult trapping in which R. zephyria is not infrequently captured near apple orchards (AliNiazee et al 1987). In addition to potentially identifying ßies caught on traps, identiÞcation of pupae from fruit could be accomplished within hours instead of the months needed when adults are reared for morphological identiÞcations.…”

The apple maggot, Rhagoletis pomonella (Walsh) (Diptera: Tephritidae), is a serious introduced quarantine pest in the apple (Malus spp.)-growing regions of central Washington and Oregon. In August 2011, seven fly larvae of unknown origin were discovered infesting fruit of an exotic Chinese crabapple, Malus spectabilis (Aiton) Borkhausen, in Kennewick, Benton County, WA. If confirmed, Chinese crabapple would have represented a new host for R. pomonella in Washington and triggered quarantine measures in a surrounding three-county region of the state. Here, we establish, based on five microsatellite loci, the identity of the crabapple-infesting larvae as the western cherry fruit fly, Rhagoletis indifferens Curran, representing a new host record for the fly. Morphological analysis of six flies reared to adulthood confirmed the genetic identification. The results demonstrate the utility of integrating rapid genetic identification methods with field surveys of economic pests, which decreased detection times by months, and avoided enacting costly quarantine measures that saved local and federal bodies > US$0.5 million in monitoring, inspection, and control costs. We discuss current ongoing efforts to develop rapid, accurate, and inexpensive on site DNA-based detection tools for R. pomonella that would have general applicability for the control of pest insects.
