Table 1 Results of cross-mating experiments of F1 adult ticks of two laboratory colonies of Ornithodoros rietcorreai n. sp., one from the state of Piauí (PI), and one from the State of Paraíba (PB), Brazil

From: A new argasid tick species (Acari: Argasidae) associated with the rock cavy, Kerodon rupestris Wied-Neuwied (Rodentia: Caviidae), in a semiarid region of Brazil

  1. aFive male and five female F2 adults from each F1 cross were left together in a vial after a blood meal; numerous larvae were born in each vial several weeks later, confirming fertility of F2 adults
  2. bThese groups consisted of only females with no contact with males, with the purpose to verify if female ticks could reproduce by parthenogenesis after a blood meal
