The termite resistance of wood impregnated with nano-zinc oxide and nano-zinc borate dispersions
2016 - IRG/WP 16-30691
In this work, the effects of the impregnation with nano-ZnO and nano-ZnB dispersions on the termite resistance of European beech wood were investigated. Three different concentrations (namely 0.5%, 1% and 2%) of the above two materials were tested. Water leaching effect was also investigated. It was concluded that a severe effect in terms of termite workers mortality is induced by the use of both ...

Wood properties modification by an enzymatic assisted treatment with phenolic extractives
2016 - IRG/WP 16-30696
Extractives of sawdust and bark from P. pinaster and, condensed tannins (CTs) from P. radiata bark were used to treat beech and pine veneers in combination with an oxidative enzyme, in order to stably graft such extractives onto the veneers. First, the antifungal activity of P. pinaster phenolic extractives against wood decay fungi was studied. These extractives were also used to hydrophobize pi...

Is the SPM 15 effective? Survival of Pine Wood Nematode under thermal treatments
2017 - IRG/WP 17-40775
The pine wood nematode Bursaphelenchus xylophilus (Steiner and Buhrer) Nickle (PWN) is the causal agent of “Pine wilt disease” affecting coniferous forests, and since its detection in 1999 in Portugal, has obligated the European Union to take action to prevent its spread (Decision 2006/133/CE). The main measure applied is the International Standard for Phytosanitary Measures ISPM No. 15 (ISPM ...

Potential of totora and derivatives as sustainable lignocellulosic material
2019 - IRG/WP 19-40859
Totora (Schoenoplectus californicus C.A. Mey. Soják) is a macrophyte from the Cyperaceae family that grows in the Americas from California to Chile. This plant has long been used by several cultures such as the Ohlone in California, the Moche in Peru, or the Incas in Los Andes. Some communities have maintained its traditional use until the present, such as the communities living nearby Lake San P...

Effect of enzymatic inhibitors on the population of Reticulitermes grassei and their associated microbiota
2023 - IRG/WP 23-11008
Termites are pests that invade urban, agricultural and forest environments worldwide. They are economically important owing to the damage they cause to wood, wood products, building materials, agricultural products and forests. There are many methods for its control, but many of them cause negative environmental effects due to their toxicity. In termites, dietary change or antibiotic treatment may...
