Control of Bactrocera oleae and Ceratitis capitata in Organic Orchards: Use of Clays and Copper Products.

Tests on the effect of clays (kaolin and bentonite) and copper products (hydroxide and oxychloride) in the control of olive fruit fly, Bactrocera oleae (Rossi), and Mediterranean fruit fly, Ceratitis capitata (Wiedemann), were carried out from 2003 to 2006 in olive groves and in organic citrus orchards (satsuma, clementine, ‘Navelina’ orange). Results demonstrate an efficacy of kaolin products in reducing attacks of B. oleae on olives and those of C. capitata on citrus fruits; in olive groves the clays gave similar or better results than copper hydroxide. Bentonite AG/8W showed a significant reduction in punctures by C. capitata. Bentonite products and BPLK kaolin are washed off by rainfall more easily than Surround WP kaolin. In contrast to the effect of copper hydroxide on B. oleae in olive groves, no tested copper product showed a significant reduction in C. capitata punctures on citrus fruits. Clays are very useful tools to control tephritid and other insects and are also environmentally friendly, but currently, they are not permitted as products for plant protection in European and Swiss organic farming

Effect of pressing method on the sensory quality of organic apple juice

There is a need for alternative, gentle processing methods that can be used for processing of organic food products. The pressing methods used for organic apple juice include the slow rack-and-frame press and the faster water press or belt press. The aim was to evaluate the influence of these three pressing methods on the sensory quality of cloudy organic apple juice produced from two apple cultivars

Le rappresentazioni del corpo "anaisthētos" nel "Corpus Hippocraticum": una 'via negativa' verso la conoscenza

This paper seeks to investigate the medical representations and descriptions of ἀναισθησία as we find them in the Hippocratic Corpus. It represents an attempt to analyze both the cognitive and the physiological aspects of perception and, above all, its distortion and/or absence in Hippocratic medicine. The medical phenomenology of ἀναισθησία will be considered in respect to both its outcomes (inability to perceive the outside world; inability to perceive one's internal states), but also in the light of, and in connection with, other phenomena like the absence/suspension of phonation, disturbances of breathing, alteration of the body's motor functions, and insensibility to pain

Primi studi sulla biologia e sul controllo di Cydia funebrana (Treitschke) in susineti biologici siciliani

First studies on biology and control of Cydia funebrana (treitschke) in Sicilian organic plum orchards. Cydia funebrana (Treitschke), considered the key pest in the Sicilian plum orchards. Few studies were carried out in Sicily concerning C. funebrana life cycle, forecasting models and the effectiveness of some products permitted in organic plum orchards. In 2010 researches were carried out in three Sicilian plum orchards, two in Palermo Province (Monreale and San Giuseppe Jato) and one in Agrigento Province (Castrofilippo), in order to monitor the population, to evaluate damage levels caused by the plum moth and to estimate how many generations it could complete by Charmillot’s forecasting model. In addition, in San Giuseppe Jato, the effectiveness of mineral oil and Spinosad, products permitted in organic farming, was evaluated on three different plum cultivars, Angeleno, Friar and Stanley. Field data showed that the plum moth completes at least three yearly generations. Moreover, clear differences have been found among the cultivars compared in San Giuseppe Jato orchard, Angeleno being the most susceptible to the moth attack. Local plum cultivars in Monreale were more susceptible to plum moth attack than all the other ones. Charmillot's model about generation numbers by temperature records, provided an overestimate of the C. funebrana generations. The only orchard in which the infestation level was very low was that in Castrofilippo. Field trials did not show adequate efficacy of tested products to reduce C. funebrana damages

Foliar Applications with SUNRED® Biostimulant Advance and Uniform Fruit Ripening in Orange and Olive

This study evaluated the effect of foliar biostimulants on fruit quality of adult 'Valencia' orange and 'Biancolilla' olive trees. Half of the selected orange and olive trees were sprayed twice before harvest with the SUNRED® commercial mix containing phenylalanine, methionine, mono-saccharides and oxylipins from plant extracts as well as potassium salts and urea. Orange and olive yields and fruit quality were measured at harvest, and fruit peel color was determined by digital image analysis. Phenolic and sensory profiles were also determined in the olive oil. In orange, the foliar spray increased TSS:acid ratio and peel color uniformity, while in olive, it increased peel color uniformity, oleocanthal, and 3,4-DHPEA-EDA and decreased oil spiciness. The results of this study suggest that foliar sprays with the SUNRED® biostimulant in pre-harvest may improve fruit quality of 'Valencia' orange and 'Biancolilla' olive by advancing and uniforming fruit ripening

Comparative Analysis of Simplified Daylight Glare Methods and Proposal of a new Method Based on the Cylindrical Illuminance

This paper analyzed the accuracy of simplified glare analysis methods compared to the Daylight Glare Probability (DGP) through a parametric study. It consisted of glare calculations in a sample office room, with varying façade layout and orientation. Calculations were performed with Radiance, obtaining the simplified and full glare indices for each case. The different options were compared for discrete daylight conditions as well as for complete annual simulations. As a final output of the research, a new metric is proposed based on the cylindrical illuminance. This has the advantage of retaining the vertical component of illuminance, while being view independen

Degenerate parabolic models for sand slides

Abstract The morphodynamic evolution of the shape of dunes and piles of granular material is largely dictated by avalanching phenomena, acting when the local slope gets steeper than a critical repose angle. A class of degenerate parabolic models are proposed closing a mass balance equation with several viscoplastic constitutive laws to describe the motion of the sliding layer. Comparison among them is carried out by means of computational simulations putting in evidence the features that depend on the closure constitutive assumption and the robust aspects of the models. The versatility of the model is shown applying it to the movement of sand in presence of walls, open ends, columns, doors, and in complicated geometries
