Western cherry fruit fly, Rhagoletis indifferens Curran (Diptera: Tephritidae),is a major pest of sweet cherry, Prunus avium (L.) L., in the Pacific Northwest of the United States. Spinosad bait is applied weekly to kill flies before they develop eggs, but its effects on oviposition by reproductively mature flies are unknown. In this study, the main objective was to identify insecticide bait tr...

To elucidate metabolism of ascorbic acid (AsA) in sweet cherry fruit (Prunus avium 'Hongdeng'), we quantified AsA concentration, cloned sequences involved in AsA metabolism and investigated their mRNA expression levels, and determined the activity levels of selected enzymes during fruit development and maturation. We found that AsA concentration was highest at the petal-fall period (0 days afte...
