Exclusion cages were used to compare the incidence and severity of feeding injury from brown marmorated stink bug, Halyomorpha halys (Stål) (Hemiptera: Pentatomidae), on ‘Redhaven’ peaches, ‘Golden Delicious’ apples, and ‘Smoothee Golden’ apples at harvest, following sequential periods of exposure to natural H. halys populations during the 2011 and 2012 growing seasons in Virginia. The fruit us...

Sixteen years of archived tufted apple bud moth, Platynota idaeusalis (Walker), trap capture data were compared with archived fruit injury data collected at the Penn State University Fruit Research and Extension Center to define the relationship of trap capture to fruit injury. Pheromone trap capture until 15 June was the best predictor of fruit injury at harvest. Using the regression equation ...

A method for locating apples was developed to process real-time video image sequences captured with an over-the-row harvester. The concepts of background modeling in RGB color were used, which is a novel approach to the apple segmentation problem. In background modeling, the distributions of background colors are approximated from real data. The algorithm developed for this task, Global Mixture...

Characterization of the spatial variability vegetative vigor in vineyards can help improve performance site-specific management practices, or with different rates. using canopy proximal sensing has been a widely disseminated technique; however, southeastern Brazil, where utilization annual double pruning results winter harvest, knowledge role improving vineyard not yet applied. This study aimed...

BACKGROUND Ethiopia faces cyclic food insecurity that alternates between pre- and post- harvest seasons. Whether seasonal variation in access to food is associated with child growth has not been assessed empirically. Understanding seasonality of child growth velocity and growth deficit helps to improve efforts to track population interventions against malnutrition. The aim of this study was ass...

MAIN OBJECTIVES Fresh fruits and vegetables become increasingly recognized as vehicles of human salmonellosis. Physiological, ecological, and environmental factors are all thought to contribute to the ability of Salmonella to colonize fruits and vegetables pre- and post-harvest. The goal of this study was to test how irrigation levels, fruit water congestion, crop and pathogen genotypes affect ...

Many important apple (Malus × domestica Borkh.) fruit quality traits are regulated by multiple genes, and more information about quantitative trait loci (QTLs) for these traits is required for marker-assisted selection. In this study, we constructed genetic linkage maps of the Japanese apple cultivars 'Orin' and 'Akane' using F1 seedlings derived from a cross between these cultivars. The 'Orin'...

Citrate is one of the most important organic acids in many fruits and its concentration plays a critical role in organoleptic properties. The regulation of citrate accumulation throughout fruit development, and the origins of the phenotypic variability of the citrate concentration within fruit species remain to be clarified. In the present study, we developed a process-based model of citrate ac...

Post harvest loss has been a bane to food security in Nigeria. Although increased crop yield has been found to be feasible. Post harvest losses especially in fruits such as citrus, banana and pineapple are enormous, the marketing system of these fruits places about 75% of the burden of these losses on the fruit marketers. This study evaluated post harvest losses in fruit marketing in Lagos metr...
