The invasive mosquito Aedes japonicus japonicus is spreading in northeastern Italy.

Background: The invasive mosquito species, Aedes japonicus japonicus, was detected in northeastern Italy for the first time in 2015, at the border with Austria. After this finding, a more intensive monitoring was carried out to assess its distribution and to collect biological data. Herein, we report the results of four years (2015-2018) of activity.

Combined magnetic resonance imaging and high resolution spectroscopy approaches to study the fertilization effects on metabolome, morphology and yeast community of wine grape berries, cultivar Nero di Troia.

Effects of fertilization practices, mineral (M) and organo-mineral (OM), on molecular composition of Nero di Troia cultivar grape berries was studied using conventional chemical analysis, Magnetic Resonance Imaging (MRI) and H NMR spectroscopy on intact berries and extracts, respectively, and through analysis of yeast species developed on grape skins. Plants vegetative status did not differ between the two fertilization practices, whereas some grape juice chemical characteristics differed in fertilized grapes. MRI provided information on grape berries morphology through weighted images depending on spin-spin (T2) and spin-lattice (T1) relaxation times.

Maceration with stems contact fermentation: effect on proanthocyanidins compounds and color in Primitivo red wines.

Three Primitivo (Vitis vinifera, cv.) red wines were microvinified by means of different winemaking technologies: no stem-contact fermentation destemming 100% of grapes (D100); stem-contact fermentation destemming 75%, 50% of grapes (D75-D50) respectively. The objectives of this work were to improve proanthocyanidins content in wine, to monitor the relationships between anthocyanins/tannins and to detect the effects on the polymerization state of polyphenols after 12 months storage of wines.
