Phoenix canariensis represents one of the most relevant ornamental plants within Mediterranean environment. In the last few years the infestation of a curculio coleopteron, namely the Rhynchophorus ferrugineus, caused a widespread decimation of these palms. Unluckily damages caused by the insect are evident only in the advanced phase of the disease making futile almost any plant treatment. Early warning of this disease may represents the only way to setup efficient actions to fight the coleopteron in trees where it takes over, thus limiting its spreading in contiguous palms. This research aims to achieve the former result by processing: i) short and long-wave images of the crown acquired during day-time by a balloon platform, and ii) a time series of thermal images of the trunk recorded during night-time on the field. The research is based on the hypotheses that: j) the disease induces changes of both transpiration processes and crown shape, because the damages of vascular tissues; jj) the local increase of temperature within the trunk, due to anaerobic fermentation established within the palm, extends up enough to surface to be diachronically analyzed to localize the disease core.© (2011) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).
