  abstract = {{B}ackground: {R}oot-knot nematodes ({RKN}) are major pest of olive tree ({O}lea europaea ssp. europaea), especially in nurseries and high-density orchards. {S}oil samples were collected from main olive growing areas of {M}orocco, to characterize {M}eloidogyne species and to discuss the contribution of biotic and abiotic factors in their spatial distribution. {R}esults: {RKN} were found in 159 soil samples out of 305 from nurseries (52.1% occurrence) and in 11 out of 49 soil samples from orchards (23.2% occurrence). {B}iochemical and molecular characterisation ({PAGE} esterase and {SCAR}) revealed the dominance of {M}. javanica both in nurseries and orchards with minor presence of {M}. incognita only in nurseries, and {M}. arenaria in only one nursery. {RKN} were distributed on aggregated basis. {F}requent presence of {M}. javanica in orchards might have come from nurseries. {I}n contrast, the detection of {M}. incognita in nurseries alone suggests that this species could not reproduce in orchards because of either the competition with other plant-parasitic nematodes or unfit local habitats. {T}he impact of environmental variables (climate, habitat origin and physicochemical characteristics of the substrates) on the distribution of {M}eloidogyne species is also discussed. {C}onclusion: {O}live nurseries in {M}orocco are not able to guarantee the safety of rooted plants. {A}s a result, olive production systems are exposed to strong {RKN} invasion risks. {C}onsequently, the use of healthy substrates in nurseries may prevent plant-parasitic nematode induction in orchards.},
