Epidemiological uses of a population model for the tick Rhipicephalus appendiculatus [PDF]
Tropical Medicine & International Health, 1999 Summary The spatial and temporal risk of tick‐borne disease depends fundamentally on the distribution, abundance and seasonal dynamics of the vector ticks. The latter factor exerts a major quantitative influence on the transmission dynamics of tick‐borne parasites.

Effects on cattle of artificial infestations with the tick Rhipicephalus appendiculatus
Parasitology, 1985 Groups of ten cattle were exposed to 0, 40 and 400 adult Rhipicephalus appendiculatus feeding once a week for 24 weeks. Although no differences in cumulative percentage weight gain were found at the end of the experiment, animals free of ticks performed better during the first 12 weeks.

The feeding behaviour of larvae, nymphs and adults of Rhipicephalus appendiculatus
Parasitology, 1976 The pre-feeding and feeding periods of larvae, nymphs and adults of Rhipicephalus appendiculatus on rabbits (Oryctolagus cuniculus) were investigated. Larvae and nymphs required at least 8–9 days after hatching and moulting respectively before they could attach and start feeding, while adults required at least 6–9 days. But longer periods of starvation
