Flight periods of the cherry fruit fly, Rhagoletis cingulata (Loew), were compared in the major sweet and tart cherry-growing regions of Michigan, among neglected orchards, managed orchards, and natural areas containing the ancestral host, black cherry. Traps were deployed from early June to late September 2005 and 2006. Captures indicated that cherry fruit fly has an early flight (June-July) i...

The genus Rhagoletis Loew includes about 65 known species distributed throughout Europe, Asia and America. Most species are oligophagous, attacking only a few closely related host plants. The European cherry fruit fly R. cerasi is the economically most important pest species in Europe. R. batava and R. alternata can also cause economic damage in Europe. In addition to these sp...

A study was conducted to determine the abundance of potential foods and the feeding substrates and behaviors of the western cherry fruit fly, Rhagoletis indifferens Curran (Diptera: Tephritidae), in 2005, 2006, and 2007 in central Washington state. Aphid colonies with honeydew, a presumed food source for flies, were not seen on randomly selected branches of sweet cherry trees, Prunus avium L., ...

The western cherry fruit fly, Rhagoletis indifferens Curran (Diptera: Tephritidae), is an endemic herbivore of bitter cherry, Prunus emarginata (Douglas ex Hooker) Eaton, but ∼100 years ago established on earlier-fruiting domesticated sweet cherry, Prunus avium (L.) L. Here, we determined if eclosion times of adult R. indifferens from sweet and bitter cherry differ according to the phenology of...

All commercial sweet cherry trees are either budded or grafted. The part of the tree above the graft/bud union is known as the scion and the part below the graft/bud union is known as the rootstock. Sweet cherry scion cultivars have been selected over millennia for many reasons, but over the past century, breeding programs have concentrated mainly on achieving improved characteristics such as y...

Automation in cherry harvesting is essential to reduce the demand for seasonal labor for cherry picking and reduce the cost of production. The mechanical shaking of tree branches is one of the widely studied and used techniques for harvesting small tree fruit crops like cherries. To automate the branch shaking operation, different methods of detecting branches and cherries in full foliage canop...

Chinese cherry [Cerasus pseudocerasus (Lindl.) G.Don] is a commercially important fruit crop in China, but its structure patterns and domestication history remain imprecise. To address these questions, we estimated the genetic structure and domestication history of Chinese cherry using 19 nuclear microsatellite markers and 650 representative accessions (including 118 Cerasus relatives) selected...

in thirty-three wild cherry (prunus avium l.) accessions from central serbia, tree, leaf, fruit, and stone morphological characters were evaluated during three consecutive years. the goal was to detect relationships between the genotypes and to identify the most useful traits for discrimination among them. the study revealed a high variability in the set of the evaluated wild cherry accessions ...

(1) Background: The aim of the study was to use innovative sensor technology for non-destructive determination and prediction of optimum harvest date (OHD), using sweet cherry as a model fruit, based on different ripening parameters. (2) Methods: Two cherry varieties in two growing systems viz. field and polytunnel in two years were employed. The fruit quality parameters such as fruit weight an...
