Biological compatibility between two temperate lineages of brown dog ticks, Rhipicephalus sanguineus (sensu lato)

Table 1 Tick groups used in this study

Group	Tick line	Specimens used
G1	Pure line of Rhipicephalus sp. II	10 females and 10 males from Portugal
G2	Pure line of Rhipicephalus sp. I	10 females and 10 males from Italy
G3	Crossed line with females of Rhipicephalus sp. II	10 females from Portugal and 10 males from Italy
G4	Crossed line with females of Rhipicephalus sp. I	10 females from Italy and 10 males from Portugal

Adult ticks used to establish both pure and crossed lines belonged to the wild type; they were obtained from nymphs that moulted from larvae obtained from wild-caught, engorged females. F₁ and F₂ generations from crossed lines are referred to as hybrids
