It has been shown that wood infected with the brown rot fungus Gloeophyllum trabeum (Pers. ex Fr.) Murr. is'more attractive to termites than sound wood. For several years, small blocks of infected wood have been used as bait to sample soil sites for the presence of termites. The method described here for bait block production is more suitable than the ASTM method for large-scale work.
