Unfed larvae of Rhipicepalus sanguineus sensu lato (Kolonin, 2009; Dantas-Torres,
2010; Guglielmone et al., in press) show a higher heat stress
resistance and tolerate 1 h of exposure to temperatures up to
50 C at a RH of 97% whileIxodes scapularis, a tick which is associated
with high humidity and mild winter temperatures, displays high mortality rates at temperatures of only 30 C (Yoder et al.,
2006).
