First report of Ornithodoros peropteryx in Brazil, and the occurrence of Ornithodoros cavernicolous in the western Brazilian Amazon [PDF]
Systematic and Applied Acarology, 2018 More than half of the Brazilian soft ticks (Argasidae) are represented by species associated with bats. Based on a morphological and molecular approach of free-living ticks collected inside two unexplored caves in Rondônia state, western Brazilian Amazon, we report the occurrence of Ornithodoros peropteryx for the first time in Brazil.

Ornithodoros moubata: Breeding in vitro
Experimental Parasitology, 1977Abstract In vitro breeding of Ornithodoros moubata (Murray) was achieved by feeding the ticks on defibrinated porcine and bovine blood through bat's wing membrane. On either type of blood, the life cycle was completed and the ticks reached equal weights and consumed equal meals.

Bioassays performed on Ornithodoros (Ornithodoros) savignyi (Audouin) demonstrated the presence of a female sex pheromone. Unfed adults and fed adults, after various postfeeding periods, were cross-tested. Two independent criteria were used: the percentage of positive male responses and the time elapsed before these responses.

Piroplasmal sporozoites in the Argasid Ornithodoros erraticus (Lucas) [PDF]
Experientia, 1977 The infective forms of Nuttallia meri, a small-mammal piroplasm, first appear as spindle-shaped sporozoites in and around the salivary glands of Ornithodoros erraticus (small race) 30 days after the ticks had fed on infected blood. O. erraticus is the only soft tick so far proved to transmit a piroplasm.
