LE SOSTANZE DI ORIGINE VEGETALE NEL CONTROLLO DEGLI ACARI FITOFAGI E GLI EFFETTI COLLATERALI SUI FITOSEIDI

2016

I metaboliti secondari con caratteristiche biocide presenti in molte piante, possono rappresentare una buona scelta per il controllo delle popolazioni dei fitofagi nei processi agricoli ecocompatibili. In particolare nelle coltivazioni gestite in regime di agricoltura biologica o biodinamica, il controllo degli acari fitofagi risulta attualmente legato solo a tecniche di controllo biologico o tecniche colturali con risultati non sempre soddisfacenti. Nella presente revisione vengono riportate notizie sull’azione di diversi estratti vegetali nei confronti di acari fitofagi, nonché notizie sugli effetti collaterali di questi estrati nei confronti di alcune specie di acari predatori.

Underestimated impact of Red Palm Weevil introduction on iandscape biodiversity: the help of the molecular tools

2012

Alien species have been introduced both accidentally and intentionally. The last are and have been motivated by economic, environmental and social considerations (NOBANIS, 2010), as in the case of many palm species (Phoenix canariensis, P. dactylifera, Washingtonia filifera, W. robusta) in Sicily. These Arecaceae are important in the urban areas and they contribute to the typical Sicilian Panorama. On the other hand the accidental introduction of invasive alien species can be one a cause of the loss of native biodiversity, especially severe on islands and other isolated ecosystems. Phytophagous insects can cause biodiversity losses and may also have a strong impact on the economy of the isl…

SICILY AS THEORETICAL MODEL TO STUDY THE POTENTIAL IMPACT OF GENETICALLY MODIFIED PLANTS IN A HOTSPOTS OF BIODIVERSITY

2015

In Europe, especially in Italy, different considerations are necessary when potential GMPs are to be grown. In particular high biodiversity areas such as Sicily should have a more detail plans of potential benefits and risks assuring the conservation of biodiversity and endemic species. Sicily is one of the most relevant biodiversity hotspots in the Mediterranean area, with a vascular flora of 3252 species and 321 endemic taxa. Considering the latest IUCN categories and criteria, 401 taxa (12.4% of Sicilian flora) are under threat (categories “CR”, “EN”, “VU”), and 220 more taxa (6.8%) are “Near Threatened”. Sicily is also known to have a rich butterfly and coleopteran fauna including endem…

IMPOVERISHMENT OF SICILIAN (ITALY) HISTORICAL AND CULTURAL ASSETS BY AN ALIEN INSECT SPECIES: THE CASE OF THE RED PALM WEEVIL.

2012

Alien invasive species (IAS) have a disastrous impact on the biodiversity, cultural heritage and economy of a geographic area. The case of the Red Palm Weevil (RPW), an IAS that attacks the non-native palm species Phoenix canariensis, but also native species Chaemerops humilis, especially in urban and peri-urban areas, is reported. These palm trees have played an important role in Sicilian history and cultural heritage since the period of the Arab invasion. The accidental introduction of the RPW has remarkably changed the Sicilian panorama. In this study the chronology and the severity of the effects of RPW on palms so far detected, is reported. In only 7 years the RPW has drastically chang…

[ES] En esta tesis doctoral se discuten una serie de cuestiones científicas relacionadas con a la producción y el procesamiento de algunas especies de cítricos de especial relevancia en Sicilia y en el área mediterránea. Los objetivos se centran en estudiar la trazabilidad y sostenibilidad de la producción de algunas especies de cítricos, así como encontrar nuevas aplicaciones a los subproductos y productos de desecho de la industria, con el fin de mejorar su rentabilidad. Por lo tanto, los temas que se desarrollarán serán los siguientes: caracterización de los compuestos bioactivos presentes en aceites esenciales y en el hidrolato de diferentes especies de cítricos; seguimiento del efecto …

Potentiality of extensive green roofs soils in sustaining Mediterranean annual dry grassland of the EU-Habitat 6220*

2015

Nature-based solutions are defined as living solutions inspired by, continuously supported by and using nature (Final Report of the Horizon 2020 Expert Group on 'Nature-Based Solutions and Re-Naturing Cities'). In line with this statement and according to the European research and innovation policy agenda, green roofs (GRs) represent a fundamental requisite for urban sustainable development, being potential stepping stones for plants and animals, including those characterizing habitats of Community interest. In our work, we tested the suitability of green roofs in hosting Mediterranean annual dry grassland of the 92/43 ECC Habitat 6220* (pseudo-steppe with grasses and annuals of the Thero-B…

Microscopic findings and soil genetic “indicators” in support of pedoarchaeological studies

2015

Archaeologists use historical artefacts and archaeological records to reconstruct the communities that produced them and the environment in which they lived. Soil protects our buried or damaged heritage of archaeological and historic remains from depletion, damage, and any disturbance. Here are presented some preliminary results obtained in the framework of the FP7 Project "MEditerranean MOntainous LAndscapes: an historical approach to cultural Heritage based on traditional agrosystems (MEMOLA)" where ancient soils horizons are themselves archaeological records. In order to implement the MEMOLA archaeological study and to identify soil genetic "indicators", two integrated approaches were us…
