Termite resistance of thermally-treated ash (Fraxinus excelsior L) and European beech (Fagus sylvatica L) against subterranean termites (Reticulitermes banyulensis) was evaluated. A laboratory no-choice feeding test following the standard EN 177 was performed to assess the efficacy of this thermo-modification against subterranean termites in the Mediterranean area. After 8 weeks period of exposure, results showed that durability against termites was slightly improved for thermally-treated beech wood, which was classified as moderately durable. However, in case of thermally-treated ash wood, samples were highly biodegraded by termites, revealing no increase in their durability and being classified as non durable. © 2013 Springer-Verlag Berlin Heidelberg.

Considering the decay risk of wood structures in temperate regions and the need to implement environmentally sound and healthy safe integrated pest management strategies, the main objective of this research was to detect xylophagous insects (especially termites) at an early stage as well as to relate the wood conditions in buildings (moisture content and temperature) to the infestation risk of the main wood-rotting fungi. To do this, an advanced sensor was developed. It sends a wireless alarm with the indication of termite activity inside the wood or with the warning signal that the conditions in the wood make it vulnerable to fungal settlement. After investigating the main detection parameters and testing different prototypes under varying laboratory conditions, a final sensor was developed for use in real conditions. Furthermore, a wireless network of these biodegradation sensors was developed and installed in three representative buildings for their automatic monitoring, forming an integral alarm system for wood degradation activity supported by an advanced remote sensing management. © 2012 Springer-Verlag.

The heartwood of Prosopis kuntzei showed excellent resistance against the basidiomycete Trametes versicolor and the subterranean termite species Reticulitermes banyulensis. The wood was classified as moderately durable in soil contact. The low mass losses are presumptively caused by leaching effects in addition to soft rot decay. © Springer-Verlag 2011.

A laboratory no-choice test following the standard EN-117 was conducted to evaluate the efficacy of wood modified with different technologies against subterranean termites of the genus Reticulitermes spp. European beech modified with DMDHEU, acetylated radiata pine, and furfurylated Southern yellow pine were used for termite testing. Before the bioassay, half the number of the specimens (including controls) was subjected to an accelerated aging test according to EN-84. The specimens were exposed for 8wk to the termites. Additionally, mass losses were measured. The results indicated that the feeding pressure was sufficient according to EN-117 for a valid test. Acetylated wood and DMDHEU-modified wood were classified as durable, showing excellent termite resistance. Furfurylated wood was resistant in the case of non-leached specimens; however, the leaching process led to a classification of non-durable. Thus, the new modification technologies open a real possibility of their use in the Mediterranean region as alternative preventive treatments against subterranean termites. © 2013 Elsevier Ltd.

We investigated the effect of wax-treated and biocide-free wood specimens against three different termite species. A laboratory no-choice test with Reticulitermes banyulensis Clément was carried out in Valencia (Spain) under Mediterranean conditions for eight weeks. Scots pine sapwood (Pinus sylvestris L.) fully impregnated with distinct waxes was used. Two field trials were conducted with Coptotermes acinaciformis (Froggatt) and Mastotermes darwiniensis Froggatt in northern Queensland (Australia) with wax-impregnated beech (Fagus sylvatica L.) for 16 weeks. All three subterranean termites are of major economic importance in their respective regions. The results indicated that feeding pressure by the termites was sufficient within all trials for a valid test. Wax-impregnated Scots pine sapwood was classified as durable. No termites survived the test. The results showed an aging process under submersion conditions, which lead to a classification of moderately durable. The paraffin treatment showed good termite resistance under both test procedures, and was classified as durable. The Australian field trials showed a decreased mass loss of wax-treated beech, in which an amide wax showed excellent termite resistance. The results indicate a clear dependence of the termite resistance on the type and ratio of wax used and the feeding preferences of the specific termite species. © 2010 Elsevier Ltd.
