Biological resistance of wood-based composites under protected, aboveground conditions
2005 - IRG/WP 05-20312
…a southern part of Japan on June 22, 1999. As expected, biological attacks developed with time, although there was no sign of decay on any MDF, HP and PB specimen after 5 years’ exposure.
Termites started attacking earlier and higher in terms of severity of damage than decay fungi. This was quite common to all…

Biological control in termite management – the potential of nematodes and fungal pathogens
2004 - IRG/WP 04-10521
A brief overview on the options for biological control of termites is presented. Many organisms have been identified as being able to kill termites, however, we do not know their real impact on field populations of termites. Most research has focused on some entomopathogenic nematodes and the…
