The resistance to the ixodid tick, Haemaphysalis longicornis (parthenogenetic Okayama strain), manifested as a reduction in engorged body weight, developed in rabbits subjected to a series of adult female infestations. A single infestation with females always produced resistance in hosts. This production appeared to depend little on the number of ticks per infestation. Unlike the previous papers, this study revealed that there was no reduction in the mean recovery rate of engorged females when ticks fed on a rabbit repeatedly infested with the ticks. A series of infestations were carried out comparatively to investigate the major biological characters of ticks, such as feeding, oviposition, and hatchability of eggs. As a result, there were no marked differences in these characters among the infestations. Especially, no differences were noticed in the concentration of ingested blood meal in detached females among the infestations. Precipitating antibodies were found in the sera of rabbits resistant to the tick-bite. They were subjected to fractionation by Sephadex G-200 chromatography and tested for sensitivity to 2-mercaptoethanol. As a result, they were proved to be of immunoglobulin of 7 S class.
