important question is the taxis <strong>of</strong> parasitoid related to the host individuals.<br />
Though most mo<strong>de</strong>ls consi<strong>de</strong>r that parasitoid individuals search their hosts<br />
randomly, it is known that parasitoid populations tend to group in regions <strong>of</strong><br />
higher concentrations <strong>of</strong> hosts.<br />
In this work, we analyze the impact <strong>of</strong> spatial refuges and taxis<br />
movement in host-parasitoid systems. Based on a coupled map lattice<br />
mo<strong>de</strong>l, we investigate the effects <strong>of</strong> habitat fragmentation induced by the<br />
refuges, consi<strong>de</strong>ring spatial variations <strong>of</strong> the parasitoid efficiency, and<br />
heterogeneous spatial pattern originated from taxis movement.<br />
Keywords - Host-Parasitoid systems, spatial refuges, taxis.<br />
