ARTHROPOD BIOLOGY New Hosts of Western Cherry Fruit Fly, Rhagoletis indifferens (Diptera: Tephritidae), and Their Relationship to Life History Characteristics of This Fly WEE L. YEE AND ROBERT B. GOUGHNOUR USDAÐARS, Yakima Agricultural Research Laboratory, 5230 Fruit on apple varieties favored R. Pomonella ripen on average 3 4 weeks earlier than those on downy hawthorn (Feder et al. 1993, 1994) (Fig. 1).Because R. Pomonella live for a maximum of perhaps 1 month in nature, apple and downy hawthorn flies must differentially time their life histories to match the difference in the fruiting phenologies of their respective host plants.

Mendax (Curran) (Diptera: Tephritidae) are major economic pests of apple and blueberry fruits, respectively, in eastern North America. The taxonomic status of these flies as distinct species has been in dispute because of their close morphological similarity, broadly overlapping geographic distributions and inter-fertility in laboratory APPLE MAGGOT (RHAGOLETIS POMONELLA) ADAPTATION. A study of the biology of the. Apple maggot {Rha^oletis pomonella), togethei. With an investigation of methods of control. C^or- Solid-phase microextraction (SPME) and gas chromatography coupled with electroantennographic detection (GC-EAD) were used to identify a new blend of volatiles from apples as the key attractants for the apple maggot fly, Rhagoletis pomonella (Walsh).

Kelly, D'Youville College Resources Facts about Hawthorn and Apple Maggot Flies (Rhagoletis pomonella)The Organisms The apple maggot fly (Rhagoletis pomonella, Walsh) is native to eastern North America. Sep 23, 2017 Rhagoletis zephyria Snow and the apple maggot, Rhagoletis pomonella (Walsh) (Diptera: Tephritidae), are morphologically similar fly species that attack white-colored snowberry fruit (Symphoricarpos spp.) and yellow/red or dark-colored apple/hawthorn fruit (Malus/Crataegus spp.), respectively (). R. Pomonella is a major quarantine pest of apples (Malus domestica Borkhausen) in The apple maggot, Rhagoletis pomonella (Walsh), also known as the apple maggot fly and railroad worm, is native to North America. Originally, it fed on the fruit of wild hawthorn ( Crataegus spp.), but then became a primary pest of cultivated apples, especially in Ovipositional responses of apple maggot (AM), Rhagoletis pomonella (Walsh), females were studied in the laboratory on apples (var: Golden Delicious) treated with different rates of four protein hydrolysate baits in choice and no-choice tests. Protein hydrolysate baits at rates of 0.5 and 1% had no significant effect, but oviposition was greatly reduced at higher rates of 5 and 10%. Rhagoletis pomonella is representative of evolution; the race that feeds on apples spontaneously evolved from the hawthorn-feeding race in 1800 to 1850 CE after apples were introduced into North America. The apple-feeding race does not normally feed on hawthorns, and the hawthorn-feeding race does not normally feed on apples. In this study, we examine the rapidity and repeatability of the evolution of diapause life-history timing in a unique circumstance involving host-associated popula-tions of R. Pomonella in the Pacific Northwest (PNW) region of the USA. Rhagoletis pomonella is native to the eastern USA.

What has contributed to incipient speciation in the maggot fly? The original habitat of the North American maggot fly, Rhagoletis pomonella, was native hawthorn trees. About 200 years ago, some populations colonized newly introduced apple trees. Apple Maggot Rhagoletis Pomonella (Walsh) Injury: In the fruit growing areas of New York State the apple maggot (AM) or "railroad worm" is one if the most serious pests of apples. All apple varieties are attacked, but summer varieties and early fall varieties are especially subject to injury. The insect also attacks certain varieties of
