ticks (ixodidae) parasitizing humans in four provinces of north-western argentina.	in four provinces of north-western argentina (catamarca, jujuy, salta and tucumán), between march 1976 and march 1990, 514 ticks were found on humans. they were identified as rhipicephalus sanguineus group (1 male), boophilus microplus (6 male, 1 female), amblyomma parvum (9 male, 13 female), a. cajannense (35 male, 30 female, 81 nymphs), a. neumanni (33 male, 41 female, 144 nymphs) and amblyomma spp. (10 nymphs, 110 larvae). most of the ticks were from the phytogeographical region of chaco, one ...	1991	1809248
ecological aspects of four species of ticks found on cattle in salta, northwest argentina.	the seasonal activity of amblyomma cajennense, amblyomma neumanni, amblyomma parvum and boophilus microplus on cattle was studied in a ranch located in the northern part of the phytogeographical district of the chaco serrano where the habitat had suffered minimal human disturbance. the female ticks on one side of 10-25 cows were counted at intervals of 20-50 days from 29 october 1985 to 5 november 1986. the percentage of cattle parasitized with larvae and nymphs of amblyomma was recorded, along ...	1990	2343535
the life cycle of amblyomma neumanni ribaga, 1902 (acari: ixodidae) in the laboratory.	a colony of amblyomma neumanni was started with engorged females collected from cattle in the province of salta (24 degrees 51's, 65 degrees 33'w), argentina. the larvae and nymphs were fed on rabbits and the adults on calves. the non-parasitic stages were maintained in darkness at 27 +/- 1 degrees c and 83-86% rh. the life cycle (pre-feeding period not tested) had a mean duration of 205.7 days. the mean time (days) for the different phases of the cycle were as follows: feeding of females 8.8, p ...	1999	10356766
biological differences between two allopatric populations of amblyomma cajennense (acari: ixodidae) in argentina.	the fertility of hybrids from two distinct populations of amblyomma cajennense from different ecological regions of northern argentina was analyzed. two colonies of a. cajennense from el rey national park (rnp), salta province (24º41's, 64º36'w), and copo national park (cnp), santiago del estero province (25º55's, 61º43'w) were established infesting rabbits with adults collected from vegetation. reproductive parameters of the first generation in laboratory of each colony and their crosses were e ...	2010	20972702
