Wild Mediterranean fruit fly females, Ceratitis capitata (Wiedemann), from an essentially monophagous population on the island of Hawaii were exposed to natural mock orange (Murraya panieulata) or sweet orange (Citrus sinensis) host fruit hung from branches of potted trees for 3-day periods in field enclosures. Subsequently, when flies were released individually onto potted trees harboring one ...

The purposes of this study were to discover dietary factors which induce or suppress the development of liver cancer, and to analyze the features of the geographic distribution of liver cancer death and related factors. First, the relation between liver cancer mortality and food consumption was analyzed by correlation coefficient analysis. Multiple regression and principal component analyses we...

Huanglongbing (HLB), considered the most serious citrus disease in the world, is associated with the nonculturable bacterium 'Candidatus Liberibacter asiaticus' (Las). Infection of citrus by this pathogen leads to reduced plant vigor and productivity, ultimately resulting in death of the infected tree. It can take up to two years following initial infection before outward symptoms become appare...

Using machine vision technology to grade oranges can ensure that only good quality of fruits is to be exported. One of the most prominent issues in the post-harvest processing of orange is the efficient determination of skin defects with the intention of classifying the oranges depending on their external appearance. Color, texture, shape and size are the important grading parameters that dicta...

In layman’s terms the Kepler Conjecture from 1611 is often phrased like “There is no way to stack oranges better than greengrocers do at their fruit stands” and one might add: all over the world and for centuries already. While it is not far from the truth this is also an open invitation to a severe misunderstanding. The true Kepler Conjecture speaks about infinitely many oranges while most gro...

Terpenoid volatiles are isoprene compounds that are emitted by plants to communicate with the environment. In addition to their function in repelling herbivores and attracting carnivorous predators in green tissues, the presumed primary function of terpenoid volatiles released from mature fruits is the attraction of seed-dispersing animals. Mature oranges (Citrus sinensis) primarily accumulate ...
