Seasonal dynamics of Larroussius species in Aragon (N.E. Spain).

Two species belonging to subgenus Larroussius (P.perniciosus and P. ariasi) were collected in Aragón (Northeast of Spain). P.perniciosus was found in all places taken into account in the study, being the most abundant species in the Mediterranean-type vegetation where it is thought it is the principal vector involved in the transmission of Leishmaniasis. On the other hand, P. ariasi was not identified in the Central area, the most dry one, of the Mediterranean zone. It reached its highest density on the Submediterranean-type vegetation where it is considered the main vector.
