In the present study table olives treated in field with kaolin and copper based products against "olive-fruit fly" were fermented using two selected strains of lactic acid bacteria (LAB). The fermentation process was monitored up to 260 days from brining through physico-chemical, microbiological and sensorial analyses. Results showed a dominance of LAB and yeasts and low level of Enterobacteriaceae counts throughout the whole process both in un-treated and treated samples. When investigating the effect of the single treatments on microbial dynamics, ANOVA results highlighted that copper based products affected significantly the control sample, while the sample inoculated with LAB starters maintained high level throughout the process, guaranteeing the fermentation process. Different behavior was revealed by yeasts population, which was partially influenced by copper treatment at the beginning of the fermentation. The polyphasic approach used in the present study, which combined sensory evaluation to microbial counts and physico-chemical characteristics, let to the conclusion on the importance of starter cultures in fermentation of table olives especially those treated with "non-conventional" pesticide, which could be used to prevent olive fly damage. © 2010 Elsevier Ltd.

The effectiveness of different methods for controlling the root-knot, Meloidogyne incognita, suitable in organic farming in protected crops, was assessed in tomato during the 2009-2010 crop cycle, on sandy soil in a coastal area of southern Sicily (Italy). The treatments tested were: 60 day soil solarization alone and combined with commercial formulations of plant extracts of Quillaja saponaria Molina, Azadiractha indica Juss., Brassica carinata A. Brown, Tagetes spp., mycorrhizal fungi (Glomus spp.), or pellets and extracts of A. indica. The formulations were applied three or four times at intervals of 30 days. Non treated plots served as a control. The application of plant extracts or the mycorrhizal fungi combined with soil solarization significantly reduced the population of M. incognita in the soil and suppressed root galling on tomatoes compared to both non treated and solarized control plots. All plant derived formulations combined with soil solarization increased marketable yield. The greatest increases were obtained using A. indica or the mycorrhizal formulations in combination with soil solarization.

The root-knot nematode Meloidogyne artiellia Franklin has been reported in various Italian regions on host plants belonging to the families Graminaceae, Leguminosae and Cruciferae, on which it is responsible for severe yield losses. It had never been detected in Sicily. In spring 2008, the nematode was found in different legume and cereal fields in the area of Caltagirone (province of Catania, Sicily). Fields infested with the nematode showed patches of stunted, chlorotic, withered and dwarfed plants. Moreover, ears of wheat were small and kernels appeared dried; finally, roots were scrubby. Infected plants were durum wheat (Triticum durum Desf.), barley (Hordeum vulgare L.), chickpea (Cicer arietinum L.), broad bean (Vicia faba L.), lentil (Lens culinaris Medik.) and vetch (Vicia sativa L.) Root observations showed brownings, small galls and mature females bearing egg masses and larvae at root bifurcations.

The amphitheater of Catania is one of the main architectural structures built during Roman domination of the town. It was constructed in two successive phases between the 1st and 2nd centuries A.D. and fell into disuse from the second half of the 4th century. Detailed geological and petrographic investigations allow better geomorphological reconstruction of the area where the monument was built. In particular, the western and eastern portions of the amphitheater are built on prehistoric lava flows, named Barriera del Bosco and Larmisi, respectively. We infer that the choice of site to build the monument was highly influenced by the morphological setting of the area. In fact, the location at the contact between two lava flow fields facilitated excavation and removal of rocks due to the incoherence of the scoriaceous lateral border of the lava flows. Integrating both archaeological and geological data has revealed that a large number of Neolithic, Greek, and Roman sites are located in the lava fields of Barriera del Bosco and Larmisi within the present urban district of Catania, indicating that during its long history the city was directly impacted by only one lava flow, namely in A.D. 1669. © 2015 Wiley Periodicals, Inc.

Prays citri (Milliere) (Lepidoptera: Yponomeutidae), citrus flower moth (CFM) is regarded as a key pest of nursery trees in Sicily. The larval activity causes damages to flowers and new shoots. In addition, the young larvae can penetrate the small fruits. The growers may spray several times per year prevalently with organophosphate insecticides. Starting from 2006 a new IPM approach was evaluated: we carried out experimental trials of different chemical compounds and tested the possibility of timing the insecticide applications by means of monitoring the male flights with pheromone traps. In the years 2007, 2010 and 2011, the efficacy of fosmet (organophosphate), flufenoxuron (Insect Growth Regulator) and Bacillus thuringiensis var. kurstaki, was evaluated on young lemon trees. The results, previously published, suggested that OPs could be substituted, or at least alternated, with IGRs and Bt for the control of CFM. Starting from 2006, pheromone (Z-7 tetradecenale) traps were placed for six years in two lemon nurseries, and the infestation level on flowers, young fruits and new shoots was recorded. The first plot (nursery located in Messina province) was subjected to an intensive spray program; the second plot (nursery located in Catania province) was submitted to a very low impact spray program. Only the data obtained in the Catania nursery produced a positive linear correlation between male captures and infestation percentage. Depending to economic target pursued, growers can themselves establish a maximum level of captures as an alert threshold.

Studies have shown that the footprint of a single eddy covariance (EC) system may not yield representative measurements of the turbulent fluxes at the field scale for sparse vegetated surfaces, whereas scintillometry, due to its larger footprint, may be more suitable for this purpose. However, the latter approach strongly relies on the Monin-Obukhov similarity theory (MOST) that strictly applies in the inertial sub-layer only. This work aims at experimentally confirm the reliability of displaced-beam laser scintillometer (DBLS) measurements over an olive orchard against two EC systems during summer and autumn months of 2007 through 2009. It was found that the DBLS underestimated both the momentum and sensible heat fluxes by 15 to 20% when established retrieval procedures were applied. A new method to determine the sensible heat flux from the DBLS based on the addition of a single-height wind speed measurement was tested, yielding estimates that compare well with the EC observations, with discrepancies in sensible heat fluxes of about 30 to 40 W m-2. © 2014 Patron Editore S.r.l.

A survey was conducted in Sicily, from 2007 to 2009, to obtain insights on specific composition, frequency and geographical distribution of cyst nematodes associated to crops of agricultural economic importance. Soil and root samples were collected mainly from crops showing chlorosis, poor growth and reduced yield. Cysts and larvae were extracted and identified to species level by comparative examination of morphological and morphometric characters. Confirmation of the species identity was also made by molecular analysis for some species. Seven species of the genus Heterodera Schmidt, 1871 and two of the genus Globodera Skarbilovic, 1959 were found. They were H. avenae Wollenweber, 1924, H. bifenestra Cooper, 1955, H. carotae Jones, 1950, H. goettingiana Liebscher, 1892, H. hordecalis Andersson, 1974, H. latipons Franklin, 1969 and H. schachtii Schmidt, G. rostochiensis (Wollenweber, 1923) Behrens, 1975 and G. pallida (Stone, 1973) Behrens, 1975. All species dectected are known to occur in Europe and the Mediterranean basin, but H. avenae, H. hordecalis, and H. latipons had not been reported from Sicily and H. bifenestra is a new report for Italy.
