“…The observation of interruption in the period of oviposition of some O. mimon females corroborates Khalil and Hoogstraal (1981) for O. amblus, in which there also was an interval in the oviposition period. The incubation period of eggs of O. mimon was similar to that noted by Schumaker and Barros (1995) for O. talaje, but shorter than that observed by Hoogstraal et al (1970) for O. musebecki. The high hatching rate ([70 %) demonstrates that the host species utilized are suitable for this tick species and can be used to establish laboratory colonies.…”

“…Although there is information in the literature on species of the Ornithodoros genus that can molt from N1 to N2 without feeding (Faccini and Barros-Battesti 2006), this is the first observation of this fact for O. mimon, despite being observed for only a few specimens of generation F1. This phenomenon was observed by Hoogstraal et al (1970) for O. muesebecki, because the N1 of this species can molt to N2 (in two to 4 days) without a blood meal.…”

“…The sexual maturity of O. mimon in both generations occurred after N2, demonstrating a specific difference when compared to other Ornithodoros species, which reach maturity only after the third or fourth nymphal instar (Hoogstraal et al 1970;Khalil and Hoogstraal 1981;Beck et al 1986;Khan and Srivastava 1988;Schumaker and Barros 1995). Besides this, the O. mimon males were more prevalent emerging from N2, while most of the females emerged from N3.…”

“…According to Hoogstraal (1985) and Sonenshine (1991), species of Ornithodoros that parasitize bats and birds remain fixed to the host for several days, thus having feeding habits similar to those of the Ixodidae. Sonenshine and Anastos (1960), Hoogstraal et al (1970), Khalil and Hoogstraal (1981) and Schumaker and Barros (1995) studied the biology of ticks that infest bats and birds, respectively, Ornithodoros kelleyi Cooley and Kohls 1941, Ornithodoros muesebecki Hoosgtraal 1969, O. amblus andO. talaje.…”

Life cycle of Ornithodoros mimon (Acari: Argasidae) under laboratory conditions

Ornithodoros mimon Kohls et al. is an argasid tick, originally described from larvae collected on bats from Bolivia and Uruguay. In Brazil the species is aggressive to humans and animals. Nymphs and adults of O. mimon were collected from the roof of a residence in Araraquara, São Paulo, Brazil, whose residents were bitten by ticks. Once in the laboratory, they were fed on rabbits and maintained in biological oxygen demand incubator at 27 ± 1 °C and 90 ± 10 % relative humidity. The females, after mating, laid eggs that resulted in larvae that were identified by the original description and also by the paratypes examination (RML 50271-50274) deposited at the United State National Tick Collection, Georgia, GA, USA. The life cycle of this species was obtained through the acquisition of two generations of ticks (F1 and F2) in the laboratory using rodents and rabbits as hosts. The biological parameters of larva, nymph and adult stages of both generations were recorded from infestations of the laboratory hosts. Larvae showed a profile of feeding for days on the host, whereas the nymphs and adults fed only for few minutes. First nymphal instar (N1) molted to second nymphal instar (N2) without blood meal. The species life cycle was elucidated for the first time.

“…Two years after, Hoogstraal (1969) described the adults of Ornithodoros muesebecki Hoogstraal 1969 from Boobie's nesting ground in the Arabian gulf, and further gave morphological details of its immature stages (Hoogstraal et al 1970). In 1973 Kitaoka and Susuki described Ornithodoros sawaii from Japan (Kitaoka and Suzuki 1973).…”

ACKNOWLEDGEMENTSThe current study represents the combined efforts of an international group of tick researchers and I am most grateful for the time that they have invested in order to contribute to this work.In first place, I would like to thank Marcelo B. Labruna for the numerous advices provided until the last analyses in the course of this study. Without his expertise, this work would be likely to include many inaccurate statements. Long and fruitful talks on soft tick systematics with him guided a great part of this work.Extensive discussions on Argasidae were also shared with José M. Venzal, who in two occasions joined the fieldwork group, and actively participated in the expedition I wish to express my sincere thanks to them all for their efforts.I was fortunate to discuss on phylogenetics with Santiago Nava; his advice was definitive when inferring evolutionary relationships for many results of this study.He also provided rapid assistance with Principal Component Analyses for sets of morphological traits from soft tick larvae, presented in the first, second and last chapter of this work. Thanks are also extended to Arlei Marcili, for his useful advices on phylogenetic tree-construction and for his devote contribution in the elaboration of many phylogenetic analyses for different chapters of the current work.A considerable contribution to the results of the current study was made by some of my laboratory fellows. I am deeply grateful to Francisco B. Costa, who taught me the PCR technique, and dedicated great efforts in cellular cultures to achieve Rickettsia isolations from Chilean ticks. Sincere thanks are also extended to Amália M. Barbieri, Fernanda Nieri and Yohana Acevedo, who also expended days in order to successfully isolate Rickettsia from soft ticks. species analyzed in this study, and therefore constitute a useful tool in order to confirm the identities and define genetic boundaries of ticks of this group in South America. Finally, the results of this study add at least five new species of Argasidae family into Chilean fauna of ticks, and point the occurrence of several forms that need further assessment in order to accurately confirm their identities.
