  abstract = {{W}e present a time discrete spatial host-parasitoid model. {T}he environment is a chain of patches connected by dispersal events. {D}ispersal of parasitoids is host-density dependent. {W}hen the host density is small (resp. high), the proportion of migrant parasitoids is close to unity (resp. to zero). {W}e assume fast patch to patch dispersal with respect to local interactions. {L}ocal host-parasitoid interactions are described by the classical {N}icholson-{B}ailey model. {B}y using time scales separation methods (or aggregation methods), we obtain a reduced model that governs the total host and parasitoid densities (obtained by addition over all patches). {T}he aggregated model describes the time evolution of the total number of hosts and parasitoids of the system of patches. {T}his global model is useful to make predictions of emerging behaviour regarding the dynamics of the complete system. {W}e study the effects of number of patches and host density-dependent parasitoid dispersal on the overall stability of the host-parasitoid system. {W}e finally compare our stability results with the {CV}2 > 1 rule.},
