    Abstract

    In the framework of an international training program organized by the University of Palermo in Siem Reap, Kingdom of Cambodia, during a visit of the National Museum in Phnom Penh, the Authors noted signs of termite attack on the external wooden beams of the southern portico of the inner garden (see Figure 1). Considering the risk connected to the presence of such insects in a wooden structure, a preliminary investigation of the roof was performed in order to verify the presence of the termites in other parts, particularly in the bearing elements of the roof structures as, in an anthropic environment, termites represent a high risk level for wooden elements [1-10]. Identification of the termite s species is very important for the proper design of any restoration intervention. In fact, drywood termites (e.g. Kalotermitidae) have colonies consisting of few thousands of individuals of the various castes and the whole nest is within the wooden element they feed on [11,12]; on the contrary, colonies of subterranean termites (e.g. Rhinotermitidae) consist of several hundreds of thousands of individuals (up to more than one million) and have their nest in the ground. They move back and forth between the nest and the wooden elements they feed on by passing through dark galleries that they build using excrements and soil grains glued together with saliva. The latter are definitely the most destructive [11-15]. These biological differences require different methodologies for disinfestation and preventive conservation.
