Laboratory evaluation of four benzoylphenylureas against two species of Reticulitermes Holmgren, 1913 (Isoptera: Rhinotermitidae) from Southwest Europe
2008 - IRG/WP 08-30472
The use of benzoylphenylureas in baits for the control of termite pest is currently increasing. The chemical compounds used have been tested mainly with American termites. The effectivity against non-American termite species must be analyzed because the worldwide use of those compounds. In this paper four benzoylphenylureas (hexaflumuron, diflubenzuron, triflumuron and noviflumuron) have been test...

Screening of fungal strains for wood extractive degradation
1998 - IRG/WP 98-10254
Fungal strains were screened for their ability to degrade apolar extractives in wood from scots pine. The degradation of total wood extractives by 91 different strains was monitored in stationary batch assays incubated for 6 weeks. The results obtained show that the ability of wood-inhabiting fungi to utilize wood extractives varied greatly, even for different isolates of the same species. Fungal ...

Laboratory study of fipronil baits against Reticulitermes grassei (Isoptera: Rhinotermitidae)
2010 - IRG/WP 10-30553
Fipronil is currently used as chemical barrier against subterranean termites, in this paper their possible use as bait has been tested. Their efficacy with Reticulitermes grassei Clément in feed forced and feed choice tests has been analyzed, evaluating the mortality caused by administration of fipronil at 1 and 10 ppm (wt/wt). Our results show that 90% mortality is achieved at 6 days with feed f...

Biosourced hybrid phenolic resins as coatings for the protection of wood and wood composites
2019 - IRG/WP 19-30745
Biosourced phenolic resins, based on the phenol-formaldheyde (PF) type, were prepared for their application as coating for wood and wood composites protection, especially against fire. The resins were synthesized by combining an organic polymeric matrix with another inorganic phase. The organic phase was prepared substituting phenol by natural phenolic compounds such as lignin and tannins. The ino...

Control biológico de la mancha azul en madera aserrada de Pinus radiata D. Don.
2008 - IRG/WP 08-10681
Radiata pine wood is highly susceptible to the attack of sapstaining fungi promoting a discoloration which results in important economical losses. The use of chemicals, a customary procedure to prevent its occurrence is becoming nowadays, due to environmental concern, a more questionable practice. The biological control of blue stain fungi with albino isolates of the Ophiostoma genera appear to ...

Joints design considerations in indoor high humidity conditions
2022 - IRG/WP 22-40950
In recent years, a number of cases of degradation by wood destroying fungi have been detected in covered timber structures such as pools, wineries, bathrooms, etc. – in fact, any building where indoor air may reach high humidity values during certain periods of time.
The origin of this kind of decay was not related to water leaks, but to the condensation of the water vapor over the steel connec...
