b The 6 morphological stages in the life cycle of Trixacarus caviae were studied on adult and new‐born guinea pigs. Established populations on adult hosts comprised: larvae 39.7%, protonymphs 26.9%, tritonymphs 17.3%, adult females 10.8% and adult males 5.3%. The structures of all 6 stages are shown in drawings; the means, standard deviations and ranges of dimensions are given. Infection was acquired within 8 h of birth on the anterior two‐thirds of the body. The density of mites on young guinea pigs increased exponentially during the first 3 weeks at the rate of 1.24 times per day.
