Conteúdo: 	The abily of guinea pigs to acquire resistence to Dermacentor andersoni and Amblyomma americanum was determined by repeatedlly infesting separate sets of guinea pigs with tick larvae. Resistence was measured in terms of reduced numbers successfully engorging and reduced weight of those ticks that engorged. An 83% redution in numbers of larvae engorging and  a 64.5%  reduction in the weight of engorged larvae were seen  between the first and second infestacions with D. andersoni. Guinea pigs exhibited considerably less resistence to A. americanum the third time they were explosed to this species than did guinea pigs infested twice with D. andersoni .
