“…The egg incubation period was the longest in the life cycle of H. rufipes. Similar results were observed for its closely related species: H. detritum (Ouhelli 1994), H. lusitanicum (Ouhelli 1994), H. impeltatum (Logan et al 1989), H. dromedarri (Ouhelli 1994) and H. asiaticum kozlovi (Chen et al 2009). The periods of female preovipositon and ovipositon and egg incubation of H. rufipes in this research were longer than those of H. rufipes described by Knight et al (1978).…”

“…The positive correlation (r = 0.909, P \ 0.05) between the weights of engorged H. rufipes females and the number of eggs laid was shown in the present study. Similar relationships were described for other tick species, H. asiaticum kozlovi (Chen et al 2009), H. anatolicum anatolicum (Snow and Arthur 1966), H. aegyptium (Sweatman 1968), Dermacentor silvarum (Yu et al 2010), Haemaphysalis longicornis (Zheng et al 2011), Rhipicephalus bursa (Yeruham et al 2000), R.

“…The present work revealed that H. rufipes had a complete life cycle of 179 days on average under laboratory conditions, which was longer than those of H. asiaticum kozlovi, H. impeltatum, H. detritum, H. aegyptium and H. dromedarii (Alahmed and Kheir 2003;Chen et al 2009;Logan et al 1989;Ouhelli 1994;Š iroký et al 2011). The egg incubation period was the longest in the life cycle of H. rufipes.…”

Biological characteristics of Hyalomma rufipes parasitising on rabbits and sheep were compared under laboratory conditions in Gansu, China. Mature ticks could parasitize both rabbits and sheep, while immature ticks only fed on rabbits successfully. Adults sucked blood on sheep significantly longer than on rabbits (16 and 13 days, respectively). Other adult parasite characteristics fed on the two hosts were similar, including the weight of engorged adult, female daily oviposition, and the weight and amount of the egg mass laid. Those indicated that this tick species showed little host specificity between sheep and rabbits during its adult stage. In total, the life cycle of H. rufipes was completed in an average period of 179 days. The average developmental periods were 59 days for egg incubation, 3 and 21 days for immature tick prefeeding and feeding, 2, 12 and 40 days for adult prefeeding, female preoviposition and oviposition. The longer female fed for engorgement, the shorter preoviposition period of engorged female needed, although when the feeding period was less than 15 days, this relationship was not obvious. The results confirmed the correlation between the weight of the engorged female and the number of eggs laid (r = 0.909). The reproductive efficiency index (REI) and reproductive fitness index (RFI) in females was 10.63 and 7.22, respectively. Engorged nymphs moulting to females were significantly heavier (27.6 ± 0.89 mg) than those moulting to males (22.3 ± 0.52 mg). Males outnumbered females by 1.4:1.

“…Assessment of the reproductive characteristics of H. doenitzi found that the weight of engorged females is positively correlated with the number of egg masses laid (r = 0.936, P \ 0.001), which is similar to other tick species such as H. longicornis (Zheng et al 2011), D. silvarum (Yu et al 2010), R. (Boopphilus) microplus (Zhang et al 2006), Hyalomma asiaticum kozlvoi (Chen et al 2009) and H. anatolicum (Ahmed et al 2011).…”

“…The mean weight (2.77 mg) of engorged nymphs moulting to females is much higher than that (1.68 mg) of nymphs moulting to males. This relationship could be used as an index to predict tick sex, as observed in H. longicornis (Zheng et al 2011), Hyalomma asiaticum kozlovi (Chen et al 2009), D. variabilis (Say) (Hu and Rowley 2000), Amblyomma cooperi (Labruna et al 2004), A. inornatum (Banks) (Gladney et al 1977) and Rhipicephalus bursa Canestrini (Yeruham et al 2000). The ratio of adult males to females is 1:1.01.…”

The paper investigated the life cycle of the hard tick Haemaphysalis doenitzi under laboratory conditions and its phylogeny based on mitochondrial 16S rDNA. The results revealed that the complete life cycle of H. doenitzi requires a mean duration of 109.6 days ranging from 91 to 137 days and the average prefeeding, feeding and premoulting periods of larvae, nymphs and females and the eggs hatching period are 18.7, 26.9, 38.9, and 25.1 days, respectively. In addition, the weight of engorged females is highly correlated with the number of egg masses laid (r = 0.936, P < 0.001). The female reproductive efficiency index and reproductive fitness index are 13.4 and 12.8, respectively. The mean weight of the engorged nymphs (2.77 mg) moulting to females is much higher than those (1.68 mg) moulting to males, which could be used as an index to predict sexes in this species. The ratio of male to female is 1:1.01. Moreover, multisequence alignments and phylogenetic tree constructed based on the mitochondrial 16S rDNA sequences suggest that H. doenitzi is genetically close to H. longicornis.

Ticks are obligate blood‐sucking ectoparasites, which not only directly damage through bites but also transmit many pathogens. China has a high diversity of tick species, 125 species have been reported, including 111 hard tick and 14 soft tick species. Many of the ticks are important vectors of pathogens, resulting in zoonoses. The dynamics of ticks are affected by both the host and habitat environment. However, systematic studies on the geographical distribution, host diversity, and specificity of ticks are limited in China. To achieve this goal, the relevant available data were summarized and analyzed in this study. Ticks are distributed in all parts of China and Xinjiang has the most records of ticks. The distribution of ticks in adjacent areas is similar, indicating that the habitat environment affects their distribution. Most ticks are widely distributed, whereas some species are endemic to their distributed regions. Ticks are parasitic on mammals, birds, and reptiles, of which mammals are the main host species. Overall, most ticks parasitize different hosts, only a few ticks have strict host specificity, such as ticks that are specifically parasitic on reptiles and bats. In addition, environmental changes and control efforts also influence the dynamics of ticks. These results can better reveal tick biological traits and are valuable for tick control.
