Resumen:
The seasonality of immature stages of Amblyomma tigrinum was studied in an area of the
Chaco phytogeographical province in Co´ rdoba, Argentina by monthly collection of larvae
from ground feeding birds and Sigmodontinae rodents, and nymphs from Caviidae rodents
from May 2005 to April 2007. An apparent peak of abundance was found from December to
May but differences with other months of the year were not significant (P > 0.05). These
and previous results suggest that the parasitic stages of A. trigrinum are active throughout
the year and has more than one generation per year at the study site. Its life cycle appears
to be regulated by temperature with no occurrence of diapause.Amblyomma tigrinum was studied in an area of the
