Abstract Studies of the tropical horse tick, Dermacentor (= Anocentor) nitens, infected with Babesia caballi showed that this protozoan parasite, a causal agent of equine piroplasmosis, is also a pathogen of its vector. In all tests, some infected ticks died 7–10 days after repletion and did not lay eggs.

Laboratory Study of Anocentor Nitens (Neumann) (Acarina: Ixodidae), the Tropical Horse Tick
Journal of Medical Entomology, 1969The parasitic stages of Anocentor nitens (Neumann), the tropical horse tick, were reared on stanchioned bovines maintained in the laboratory in an environment of 21°–27°C and 60–80% RH. A fine-mesh cloth was glued to the animal in order to confine closely all stages on the host. The length of the parasitic cycle was 25–35 days, and the percentage yield

Journal of Medical Entomology, 1992
The ovipositional biology and egg development of the tropical horse tick, Dermacentor (Anocentor) nitens (Neumann), was observed at four temperatures (20, 25, 30, and 35 degrees C) and relative humidities (40, 61, 75, and 91% RH). Relative humidity had little effect on length of preoviposition and oviposition periods.

Effect of Photoperiod on Patterns of Oviposition of Anocentor Nitens Neumann (Acarina: Ixodidae)
Journal of Medical Entomology, 1969When females of A. nitens were exposed to 1 of 4 photoperiods at constant conditions (27°C and 80% RH), peak daily oviposition occurred 2–6 days after the onset of oviposition. Photoperiod was a significant factor in the daily production of eggs but the initial weight of A. nitens has a greater effect.

Parasitology Research, 2010
The present study evaluated the acaricidal activity of essential oils from Eucalyptus citriodora and Cymbopogon nardus on non-engorged larvae of Amblyomma cajennense and Anocentor nitens. In order to carry out the study, six groups were formed, each concentration being a treatment (6.25%, 12.5%, 25%, and 50%, respectively) and also with the creation of

Rhythm of engorgement and detachment of Anocentor nitens females feeding on horses
Veterinary Parasitology, 2006The present study evaluated the engorgement and drop-off rhythms of Anocentor nitens females feeding on horses. Drop-off rhythm was evaluated at 6h-intervals (06:00, 12:00, 18:00, and 00:00 h) on horses held in stalls or in a pasture. A new method of marking feeding female ticks (the bowknot technique) was developed to evaluate ticks on horses in ...

Presence of Sex Pheromones inAnocentor nitens(Acari: Ixodidae)
Journal of Medical Entomology, 1999The aim of this study was to investigate whether there are sex pheromones in the tropical horse tick, Anocentor nitens (Neumann). When virgin males and females, fed on rabbits for 3-7 d, were tested reciprocally, there was a direct correlation between attractiveness and the period of feeding; attraction was greater (and with the fastest responses) in ...

Larval Survival of Anocentor nitens Under Simulated Natural Conditions
Annals of the New York Academy of Sciences, 2000Abstract: Basic knowledge about the survival of free living stages of ticks is of great importance as a practical tool to improve control methods. For Anocentor nitens there is little information on this subject. Eighty‐four engorged females were incubated at 30°C and 100% relative humidity.
