Anoplophora chinensis and A. glabripennis, two longhorned beetles, are natives of Asia and are considered some of the most dangerous woodborers worldwide. Their infestations often go undetected for several years, allowing both species to colonize new areas undisturbed and reach population levels which are difficult to eradicate. In Italy, A. chinensis was first detected in 2001 near Milan, and in over a decade the Lombardy Plant Protection Service (PPS) has developed enough experience to contain this xylophagous pest. Thanks to these efforts, the Lombardy PPS staff realized that public awareness is pivotal for a successful and effective eradication program. Since the beginning of the infestation, the Lombardy Region has mounted a notable campaign of information through communication media designed to inform residents of the problem. The tools used have yielded interesting results. © 2014 OEPP/EPPO. Source

Biomass and Bioenergy

Improving the knowledge of anaerobic digestion process parameters can lead to a reduction of anaerobic digestion units' start-up phase with subsequent increase of their competitiveness. For this reason the start up phase of a pilot scale biogas plant fed with cattle manure underwent a six weeks fully monitoring during which we recorded daily and specific biogas and methane productions as well as process parameters like temperature of the biomass inside the fermenter, feeding amount, digestate pH and FOS/TAC value (the ratio between organic acids content, expressed as g m -3 of equivalent acetic acid, and total inorganic carbon content of the fermenting biomass, expressed as g m -3 of CaCO 3). All data underwent multivariate statistical data processing based on principal component analysis (PCA) and linear discriminant analysis (LDA). At varying of the time required by the settling of biogas production (six weeks) different moments were differentiated and classified: according to multivariate analysis, among all the monitored process parameters, the FOS/TAC value was the one which better gave account of anaerobic digestion establishment and stabilization. © 2011 Elsevier Ltd.
