Abstract
Guinea pigs acquire resistance to the feeding of larvae of the ixodid ticks Dermacentor andersoni and Amblyomma americanum after one infestation of the respective species. In challenged hosts, the resistance was manifested by a reduction in the numbers of larvae completing engorgement and a decline in the weight of engorged ticks. Both Dermacentor andersoni and Amblyomma americanum resistant guinea pigs were cross resistant to Dermacentor variabilis. Results from injection of tick salivary gland antigen from the three tick species intracutaneously into resistant guinea pigs support the above findings relative to cross reactions. Evidence is presented to suggest that ticks with long, deeply penetrating mouthparts are less susceptible to host resistance responses produced as result of tick feeding.
