Many fruit boring insect pests are difficult to control because of the short time span during which the damaging stage can be targeted before it becomes protected by the host fruit. We investigated the host location behaviour of the codling moth Cydia pomonella (L.) (Lepidoptera: Totricidae) to its apple host ( Malus domestica Mill.) in the laboratory, with a view to the potential for extending...
IMPORTANCE Fruit consumption is believed to have beneficial health effects, and some claim, "An apple a day keeps the doctor away." OBJECTIVE To examine the relationship between eating an apple a day and keeping the doctor away. DESIGN, SETTING, AND PARTICIPANTS A cross-sectional study of a nationally representative sample of the noninstitutionalized US adult population. A total of 8728 adu...
Apple maggot, Rhagoletis pomonella (Walsh) (Diptera: Tephritidae), is a pest of major concern to apple, Malus x domestica (Borkh.) production in eastern North America. Host plant resistance to apple maggot among apple germplasm has been previously evaluated among a small number of exotic Malus accessions and domestic hybrid selections. However, a large number of exotic accessions housed in USDA...
Infield pre-sorting is intended to remove processing-grade (inferior) fruit that are not suitable for the fresh market, so growers can handle sorted apples differentially in postharvest storage and packing achieve cost savings. To this goal, we developed an apple infield grading sorting system, which singulation, rotation, transportation achieved by using simple, compact pitch-variable screw co...
in this paper, productivity of and demand for water throughout eqlid’s sugar beet growers in 1385 were investigated. to address the objective 100 growers were selected using two-stage cluster sampling, then required dataset was obtained by interviewing and completing questionnaire. in order to study factors affecting sugar beet production, cobb-douglas production function was applied. based on ...
Apple maggot fly, Rhagoletis pomonella (Walsh) is a major pest causing considerable economic losses of fruits in North America. During the development of international trade, apple maggot fly has become a threat to Chinese agriculture. In this study, CLIMEX and ArcGIS were used to predict the potential geographical distribution of apple maggot fly in China. The parameters used in CLIMEX for app...
Apple is a fruit crop cultivated worldwide. Apple orchards are exposed to a diverse set of environmental and biological factors that affect the productivity and sustainability of the culture. Many of the efforts and costs for apple production rely on reducing the incidence of fungal diseases, and one of the main diseases is apple scab caused by the fungus Venturia inaequalis. The economic impac...
The most crucial problem of apple harvesting robot is to get the exact location and the maturity degree of the target. A system of apple maturity discrimination and positioning based on the multi-spectral technology and laser triangulation ranging principle is researched. Signal transmission, signal reception, signal processing, the CPU processing and several PC components are involved in the s...
To growers, stickiness means higher costs for insect control and reduced cotton marketability. To ginners, stickiness may mean special handling and processing requirements. At the textile mill, stickiness means reduced processing efficiency, lower yarn quality, and in severe cases total shut down. For everyone concerned, stickiness means reduced profitability. Stickiness occurs when excessive s...
In the current study, the fatty acids composition of 30 monovarietal apple juices from six cider apple varieties belonging to two categories was analyzed. The different apple juices were obtained from three consecutive harvests (1997, 1998, and 1999). The fatty acids concentration in apple juice together with chemometric techniques such as principal components analysis (PCA), soft independent m...
