DIFFUSIONE DI CLOSTEROCERUS CHAMAELEON (GIRAULT) INTRODOTTO IN SICILIA, SARDEGNA E CALABRIA PER IL CONTROLLO BIOLOGICO DI OPHELIMUS MASKELLI (ASHMEAD…
2008
Ophelimus maskelli, eulofide galligeno di Eucalyptus spp., introdotto in Italia nel 2000, provoca disseccamento e caduta anticipata delle foglie attaccate. Nel 2003 è stato avviato dal Volcani Center (ARO, Israele) e dal CSIRO (Australia) un programma di controllo biologico, introducendo nel 2005 in Israele il parassitoide eulofide Closterocerus chamaeleon (Girault). Nella primavera 2006 l’istituzione israeliana ha inviato al Dip. SENFIMIZO di Palermo foglie di Eucalyptus con migliaia di galle parassitizzate da C. chamaeleon. Dopo i necessari test sulla valutazione del rischio ecologico dell’introduzione, nella prima metà di maggio il parassitoide è stato rilasciato in Sicilia in cinque euc…
Phytotoxic effects of Lantana camara, Eucalyptus camaldulensis and Eriocephalus africanus essential oils in weeds of Mediterranean summer crops
2009
Abstract The essential oil composition of Lantana camara , Eucalyptus camaldulensis and Eriocephalus africanus was analyzed by means of GC and GC–MS and bioassayed in order to determine their activity against Amaranthus hybridus and Portulaca oleracea . E. camaldulensis essential oil, with spathulenol as the main compound, was the most effective, completely inhibiting germination and seedling growth on both weeds. The essential oil of E. africanus , rich in artemisia ketone, showed activity similar to that of E. camaldulensis on A. hybridus , but it was not so effective against P. oleracea , and L. camara essential oil, with high percentages in sesquiterpene hydrocarbons, also showed higher…
Sensory analysis integrated by palynological and physicochemical determinations plays a key role in differentiating unifloral honeys of similar botan…
2015
Summary Myrtaceae honeys produced in Sierra Morena (southern Spain, Andalusia) are obtained from both Eucalyptus camaldulensis and Myrtus communis, and honeys can be easily confused when classified as they come from the same botanical family. The characterisation was intended on the basis of their physicochemical, sensory and palynological properties. Cluster analysis (CA) and principal component analysis (PCA) allowed us to make a distinction between two honey profiles. The first one corresponds to the European sensory profile described for Eucalyptus unifloral honeys. The second profile, which sensory characteristics are absolutely different, has not been previously described. Classificat…
Carbon stocks in a 50‑year‑oldEucalyptus camaldulensisstand in Sicily, Italy
2015
Eucalyptus stands in semi-arid areas may contribute to enhance carbon (C) stocks in both biomass and soil. However, the limited information available is mainly focused on short-rotation plantations. In this study, the above- and below-ground C pools in five 50-year-old Eucalyptus camaldulensis Dehnh. stands planted on Miocenic evaporitic deposits in Sicily, Italy, with a xeric and thermic pedoclimate, were measured. Above-ground biomass was determined by partitioning and weighing branches, stem and leaves. Below-ground C pools included the determination of litter, root biomass, and soil organic and inorganic C. In terms of the above-ground biomass, the E. camaldulensis stand accumulated on …
