  abstract = {{P}ontoscolex corethurus ({M}uller, 1857) is the most common invasive earthworm in disturbed lands in the tropics. {C}onditions required for its successful colonization of new plots are still not understood since some areas can be invaded while others, sometimes in the vicinity, are not. {W}e kept newly hatched {P}. corethrurus in a wide range of {A}mazonian soils where population densities had been previously evaluated. {W}e identified soil conditions that best sustain survival, soil ingestion and growth of {P}. corethrurus in controlled laboratory conditions and checked if presence/absence in the field was consistent with laboratory observations. {W}hile p{H} and {C}a influenced survival; {M}g and {C} content were the greatest determinants for growth and {C}:{P}, {M}g and clay contents determined soil ingestion rates. {S}oil ingestion and growth rate were correlated. {T}here were no differences in earthworm soil ingestion rates between invaded and non-invaded soils. {H}owever, growth rate and survival were higher in soils from invaded sites than in soils from non invaded sites, indicating that soil quality may play a role in the invasion process. {W}e identified two cases where {P}. corethrurus did not occur: (1) unfavourable soil texture and chemical properties, but also some areas with and (2) favourable soil texture and chemical properties but no invasion. {O}ther parameters, like vegetation cover (grass or trees), soil structure and compaction, soil hydrologic processes or biotic resistance of native earthworm communities could potentially also be key elements for understanding why {P}. corethrurus populations occur in some sites and not in others.},
