Abstract

Abstract Scars caused by the ovipositional and feeding activities of the western flower thrips, Frankliniella occidentalis (Pergande), on ‘Thompson Seedless’ and ‘Calmeria’ table grapes, Vitis vinifera L., had no effect on many measurable quality attributes of the fruit. Scarred berries showed no apparent differences in size or average weight when compared to undamaged fruit. However, scarred ‘Thompson Seedless’ berries had a higher soluble solids content. The acid content was not affected by any type of scar and all fruit had soluble solids to acid ratios of at least 20:1. Scarring did not affect the weight loss of fruit in short-term storage at 0.6°C, and scarred berries were not injured by sulfur dioxide fumigation.
