Indagini sulla presenza di Prays oleae in oliveti a conduzione biologica della Sicilia occidentale
Investigations on presence of Prays oleae in organic olive orchards of western Sicily. This paper reports a study on the population dynamics of the olive moth, Prays oleae (Bern) (Lep., Plutellidae) in four organic olive orchards in western Sicily (Italy), from 2007 to 2010. The influence of the phytophagous on the fruit drop was detected. Also, the efficacy of treatments with Bacillus thuringiensis var. kurstaki on damage reduction was evaluated. Flight trend was monitored using delta-wing traps (3/ha) containing the sexual pheromone ((Z)-7-tetradecenal), placed in each olive orchard. Traps were hung in the inner zone of the canopy to a height of 1.50 m, and checked weekly from May to 2-3 …
The Pattern of Rare Earth Elements Like a Possible Helpful Tool in Traceability and Geographical Characterization of the Soil-Olive System (Olea europaea L.)
The identification of a product, with its geographical origin, is a guaranty of the value of the foodstuff and protection from potential fraud. Extra virgin olive oil is produced or marketed as a single variety or a blend of two or more cultivars, often of different geographic origins. Therefore, to study a possible link between the soil and olive oil, we accounted crucial to analyse the behaviour of olive of different cultivars. We studied Rare Earth Elements (REE) amounts and their relationship to trace their distribution from soil to the olive pulp (Olea europea L.). The results obtained pointed out that the different cultivars of Olea did not drive significant differences in reciprocal …
Distribution of YLOID in soil-grapevine system (Vitis vinifera L.) as tool for geographical characterization of agro-food products. A two years case study on different grafting combinations.
The knowledge of a chemistry relationship between the soil and the agricultural products is an important tool for the quality assessment of food. We studied YLOID (Y, La and lanthanoids), recognized as very useful tracers due their coherent and predictable behavior, to trace and evaluate their distribution from soil to the grape in Vitis vinifera L. Because much of the world’s viticulture is based on grafting, and rootstocks have proved affect vine growth, yield, fruit and wine quality, we carried out experimental trials to analyse the YLOID distribution of two different red cultivars, grafted onto six different rootstocks, on the same soil. The YLOID amounts, the relationship Heavy vs Ligh…
DETERMINATION OF YLOID IN SOIL AND GRAPEVINE SYSTEM (VITIS VINIFERA L.) BY ICP-MS TECHNIQUE: A HOPEFUL PROXY FOR THE GEOGRAPHICAL CHARACTERIZATION OF FOOD PRODUCTS? A VALIDATION STUDY WITH DIFFERENT VARIETIES AND ROOTSTOCKS
The rising importance given from legislators and consumers to provenance of food purchased and/or eaten, in last years motivated several researches to identification of the geographical origin of food. The knowledge of a chemistry relationship between the soil and the agricultural products is an important tool for the quality assessment of food. YLOID (Y, La and Lanthanides) have recognized as very useful tracers because of their generally coherent and predictable behavior. This behavior can also be applied to explain the mechanisms of element intake by plants. Current knowledge suggests no preferential sorption of any element in overall root samples as well as in epigeal samples of several…
Strategie di controllo di Bactrocera oleae (Rossi) con metodi alternativi agli interventi convenzionali in oliveti biologici della Sicilia occidentale
This work reports studies on the population dynamics and safe control strategies of Bactrocera oleae in four unsprayed olive groves of western Sicily from 2007 to 2010. The main management tools for B. oleae evaluated were the“Attract and Kill” lures (Ecotrap Vioryl), the use of sardines (traditional practice) and Nu-lure (innovative) and the spinosad (innovative) which is a selective insect control product produced by the fermentation of a naturally occurring soil bacterium, Saccharopolyspora spinosa. Flies trend were carried out by pheromone traps and the level of infestation counting the number of fruits with pest eggs, larvae and pupae and hole hatching. Results showed that in all olive…
