Abstract : Observations on parthenogenetic development of 4 tick generations showed: (1) adult stages feed for 5 or 7 days; (2) female ticks commence oviposition on day 5 or 6, very rarely on day 3, and terminate oviposition 16 or 23 days later; (3) emergence of larvae commences 22 days after beginning of oviposition, and terminates 36 or 38 days later; (4) larvae feed for 3 to 5 days; in summer when massive numbers of larvae were placed on animals, detachment was observed after 2 1/2 or 3 days; (6) engorgement of nymphs lasts 4 to 6 days, and feeding process may last 7 or 8 days; (7) engorged nymphs molt into adults in about 10 or 15 days; (8) depending on size, female ticks do not lower their ovipositing productive capacity for 4 generations, and deposit from 804 to 2,579 eggs; (9) anomalies in structure of ticks, except in one case, have not been observed.
