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 effect of infestations of mango seed weevil, Sternochetus mangiferae (F.), on premature fruit drop of mangoes was investigated. Mango fruits ('Haden') of equal size were collected both off the ground and from the tree at four times during the season (June-August). If weevil-infested fruit were more prone to dropping than uninfested fruit, the prediction was that a higher infestation rate wo...

Fruit of European seedless cucumber were grown in a greenhouse under low and high phosphorus (P) fertilization regimes. Tissue P concentration of fruit (number one grade) from low-P plants was, on average, 45% of that of fruit from high-P plants. Fruit P status affected membrane lipid chemistry and fruit respiration after harvest. Mesocarp tissue of low-P fruit had a lower concentration of phos...

Concentrations of the macronutrients (K, Ca, Mg, Na, P and S) and micronutrients (Fe, B, Zn, Mn and Cu) in whole fruit, pulp, rind and albedo of fruit from young and mature 'Bellamy' navel orange trees were measured at fortnightly intervals during fruit development. The general order of abundance of the macronutrients were K > Ca > Mg ˆ P > S > Na and the abundance of the micronutrients followe...

In this study, the authors evaluated the effectiveness of the Energize Your Life! social-marketing campaign pilot study to improve knowledge, attitudes, and fruit intake among community college students. The authors used a cross-sectional, quasi-experimental, pre- and posttest design. They randomly selected community college students (N = 1,367) and exposed the intervention campus to fruit fair...

Auxin is one of the most prominent phytohormones regulating many aspects of fleshy fruit development including fruit set, fruit size through the control of cell division and cell expansion, and fruit ripening. To shed light on the role of auxin fruit ripening, we have previously shown that Sl-ARF4 is a major player in mediating the auxin control of sugar metabolism in tomato fruit (cv MicroTom)...

We applied a semi-mechanistic model of fresh matter accumulation to peach fruit during the stage of rapid mesocarp development. The model, which is based on simple hypotheses of fluid flows into and out of the fruit, assumes that solution flow into the fruit increases with fruit weight and transpiration per unit weight, and decreases with the maximum daily shrinkage of the trunk, which was used...

Rhagoletis juglandis Cresson is a specialist that deposits its eggs into the husks of developing walnut fruit. Like other walnut infesting ßies in the R. suavis group, R. juglandis actively superparasitizes its larval hosts. However, little is known regarding the degree to which hosts are reused and the ecological context under which host reuse occurs. This Þeld study examined the pattern of ho...

Plant species that bear fruit often utilize expansion of an ovary (carpel) or accessory tissue as a vehicle for seed dispersal. While the seed(s) develop, the tissue(s) of the fruit follow a common progression of cell division and cell expansion, promoting growth of the fruit. Once the seed is fully developed, the fruit matures and the surrounding tissue either dries or ripens promoting the dis...
