  abstract = {{T}runk phloem necrosis ({TPN}) is currently one of the most economically important diseases of the rubber tree ({H}evea brasiliensis). {I}nvestigations of the aetiology of the disorder have failed to identify any biotic causal agents but a multidisciplinary study has recently suggested that the disease may be caused by a combination of exogenous and endogenous stresses. {T}hese stresses can affect plant physiology and may also have an impact on soil biology and soil biochemistry. {I}n this study, macrofauna diversity and soil enzyme activities were compared for the soils under trees affected by {TPN} and under healthy trees. {P}rincipal component analysis revealed associations between {TPN} and macrofauna diversity and soil enzyme activities. {G}roups of ants and termites were associated with the soil under healthy and trees affected by {TPN} respectively. {P}olysaccharidase (cellulase, xylanase and, particularly, amylase) activities were lower in the soil under trees affected by {TPN} whereas {N}-acetylglucosaminidase activity was higher. {T}hese findings suggested that termite density and {N}-acetylglucosaminidase activity are useful indicators of {TPN}, while lower values of polysaccharidases activities are the consequence of this disease. {T}he impact of {TPN} on soil ecosystem was discussed.},
