Immature stages of Amblyomma lepidum were fed on rabbit ears and the adult ones on calf ear. There was a three-host type of development during an average period of 160.5 days. The mean larval feeding period was 5 days, 7 days for nymphs and 14.5 for females. At 27 ± 1°C and 100% r.h. the engorged larvae required 21 days for moulting and nymphs took 22 days to develop to adults. The pre-oviposition period was 14.2 days and the oviposition period was 21.4 days during which a mean number of 7564.6 eggs were laid. Hyalomma anatolicum anatolicum and Rhipicephalus evertsi evertsi were fed on rabbit ears. The larvae, nymphs and adults of Hyalomma ticks fed for 4.6 and 8.5 days, respectively. The larvae and nymphs of R. e. evertsi fed sequentially on the same host for 14 days while the females took 7.5 days to engorge. At 27 ± 1°C and 75–80% r.h. the engorged larvae and nymphs H. a. anatolicum moulted after a further 8.5 and 13 days respectively. The engorged nymphs of R. e. evertsi at 27 ± 1°C and 75–80% r.h. moulted 14.5 days after dropping off the host. At 27 ± 1°C and 75–80% r.h. the preoviposition and oviposition periods of H. a. anatolicum were 4.6 and 20.8 days, while those of R. e. evertsi were 5.4 and 14 days. The average number of eggs laid per female under the same conditions (27 ± 1°C and 75–80% r.h.), was 4684.6 for H. a. anatolicum and 3392 for R. e. evertsi.
