“…The engorgement by feeding complexes is a finding previously reported by several authors studying blood feeding by argasid and ixodid ticks (Lavoipierre and Riek, 1955;Sweatman and Gregson, 1970;Tatchell et al, 1971). However, while the feeding complex identified here has only suction and salivation periods, other authors have also identified resting periods as part of the single feeding complex.…”

“…Chelicerae movements were not observed during the engorgement phase. However, Lavoipierre and Riek (1955) reported occasional chelicerae movements after the beginning of blood suction in argasid ticks.…”

“…Ixodid ticks have various inactivity periods (also named resting periods), which can last several minutes (Gregson, 1969;Sweatman and Gregson, 1970;Tatchell et al, 1971). In argasids, Lavoipierre and Riek (1955) reported long periods of inactivity at the beginning of feeding (mainly for Ornithodoros moubata and O. tholozani var. typicus) that occurred shortly after the bite (especially after the salivation), whereas Zheng et al (2015) did not comment about inactivity periods of O. turicata feeding on artificial feeders with cattle blood.…”

“…The tick is an obligatory hematophage in all stages and remains in contact with its host for varying periods, from a few minutes or hours (nymphal instars and adults) to days (larvae) (Costa et al, 2015;Lavoipierre and Riek, 1955;Ribeiro et al, 2013). Although contact with their host is for a short period of time, it is crucial because their success in obtaining blood will affect their survival, development and reproduction (Anderson and Magnarelli, 2008); moreover, the short period of contact also reduces the risk of being perceived and killed by the host (Rossignol et al, 1985).…”

Ornithodoros rostratus is an argasid tick and its importance is based on its hematophagy and the resulting transmission of pathogens such as Rickettsia rickettsii and Coxiella burnetii to its vertebrate hosts. In the face of a lack of physiological studies related to hematophagy in argasid ticks, this paper aims to identify and characterize the events that occur throughout the feeding by O. rostratus on live hosts. Electrical signals and alterations on the feeding site were monitored using intravital microscopy and electromyography. The analyses allowed for the characterization of four distinct events: suction, salivation, chelicerae movements and inactivity. Feeding was divided into two distinct phases: (1) penetration of mouthparts (when only salivation and chelicerae movements occurred) and the formation of the feeding pool (salivation and chelicerae movements with the first signs of suction) and (2) engorgement, during which chelicerae movements ceased and blood intake took place in feeding complexes (salivation followed by suction). Variations in patterns of the electrical signals, suction frequency and salivation showed four distinct subphases: (2a) suction with electrical signals of irregular shape, increased suction frequency and decreased salivation frequency throughout blood feeding; (2b) suction with electrical signals of symmetrical shape, high suction rates (3.8 Hz on average) and feeding complexes lasting for 7.7 s; (2c) suction with electrical signals of irregular shape, high suction frequency and feeding complex lasting 11.5 s; and (2d) electrical signals with no profile and the longest feeding complexes (14.5 s). Blood feeding ended with the withdrawal of the mouthparts from the host's skin.

“…Soft ticks feed fast and expand rapidly ingesting >10 times their body weight in blood (Balashov, 1972). Excess water is secreted via the coxal organs located between coxae I and II (Lavoipierre and Riek, 1955;Lees, 1946). Initial lysis of some red blood cells occurs, but the majority is not immediately lysed (Balashov, 1972;Coons et al 1986).…”
