Chemical composition of volatile and fixed oils from of Salvia argentea L. (Lamiaceae) growing wild in Sicily.
2015
The chemical compositions of the essential oil and of the non-polar extracts (petroleum ether, dichloromethane) of the aerial parts (flowers, leaves and stems) of Salvia argentea L. were determined by GC-FID and gas chromatographyâmass spectrometry analysis. 14-Hydroxy-α-humulene (40.1%) was recognised as the main constituents of the essential oil of S. argentea, together with 1,3,8-p-menthatriene (12.1%), globulol (7.4%) and β-sesquiphellandrene (5.8%). Tritriacontane (9.9% and 14.1%), heptacosane (8.4% and 10.5%), hentriacontane (8.3% and 10.9%), tetradecanal (8.4% and 10.2%) and methyldotriacontane (7.9% and 7.6%) were recognised as the main constituents of the extracts in petroleum …
Le isole Pelagie: un luogo straordinario anche per la fauna.
2015
Lampedusa e Linosa sono isole molto diverse fra loro, una calcarea, l’altra vulcanica; quindi è comprensibile che la fauna sia in buona parte differente. Tuttavia la maggioranza delle specie vi sono migrate attivamente o, nel caso di Lampedusa, rappresentano la testimonianza di un antico collegamento con la Tunisia. L’importanza faunistica delle Pelagie è dovuta ai taxa endemici ma anche alla presenza di specie africane al limite geografico della loro distribuzione (Lampedusa, di natura calcarea, si trova infatti sulla piattaforma continentale africana).
È possibile il biologico per le olive da mensa?
2017
La frontiera dell’olivicoltura biologica da mensa passa attraverso il controllo della mosca delle olive in aree pandacie a forte pressione del dittero. In queste aree è di grande ausilio l’irrigazione, che facendo raggiungere prima la pezzatura desiderata, consente di sfuggire in parte alle più dannose infestazioni d’inizio autunno; in assenza d’irrigazione, spesso le drupe, all’arrivo delle piogge, aumentano in volume insieme alle infestazioni. I mezzi di controllo suggeriti sono quasi totalmente volti a evitare l’attacco, mediante l’uccisione degli adulti (catture massali o “attract and kill”) o la repellenza (argille e composti del rame); se si esclude l’uccisione delle larve di prima …
Effectiveness of clays and copper products in the control of Bactrocera oleae (Gmelin)and Ceratitis capitata (Wiedemann) in organic farming
2008
Tests on the effect of clays (kaolin and bentonite) and copper products (hydroxide and oxychloride) in the control of olive fruit fly, Bactrocera oleae (Gmelin), and Mediterranean fruit fly, Ceratitis capitata (Wiedemann), were carried out from 2003 to 2006 in olive groves, and in 2005 and 2006 in organic orange orchards (early ripening cv. Navelina). Results demonstrate an efficacy of kaolin products in reducing attacks of Bactrocera oleae to olives and those of Ceratitis capitata to oranges. In olive groves, they gave similar or better results than copper hydroxide. Bentonite AG/W8 showed a significant reduction in punctures towards C. capitata. Bentonite products and BPLK kaolin are clea…
Influenza dell’altitudine e di due tecniche agronomiche sull’infestazione e i danni indiretti causati da Lobesia botrana (denis et Schiffermüller) (L…
2011
Two years (2008-2009) field observations were carried out to evaluate the effects of altitude, of kaolin application and of early leaf thinning practice on the infestation level and damages caused by grape moth Lobesia botrana. The difference of 80 m. a.s.l. significantly influenced the infestation level of grape moth, which was lower, of about 20%, at the higher altitude. The early leaf thinning practice did not influence the grape moth infestation nor the presence of sour bunch rot and grey mould on grapes. On the other hand, kaolin sprayings significantly reduced the infestation level in both altitudes (from 11 to 22%) as well as the presence of sour bunch rot and fungi. However, the per…
Effect of farming system and cheesemaking technology on the physicochemical characteristics, fatty acid profile, and sensory properties of Caciocaval…
2012
Abstract Caciocavallo Palermitano is a typical stretched-curd cheese that has been produced over the centuries in Sicily according to traditional cheesemaking technology and using raw milk from autochthonous cow breeds reared at pasture. The objective of this experiment was to evaluate the effects of the farming system and processing technology on the characteristics of Caciocavallo Palermitano cheese, with particular regard to the fatty acid profile. The farming system was either extensive, using autochthonous cows fed a pasture-based diet, or intensive, with specialized dairy cow breeds fed mainly hay and concentrate. The cheese-processing technology was either artisanal, using traditiona…
