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.

Thermal Constant Estimation in Tropical Horse Tick, Anocentor nitens (Acari:Ixodidae)
Annals of the New York Academy of Sciences, 2000Abstract: Experience has demonstrated that the exclusive use of acaricides as a control method against cattle ticks causes several problems, and is not totally effective. Other methods need to be added in order to achieve better and more profitable control of these parasites.

The objective of this study was to investigate some aspects of horse resistance to natural infestations of Anocentor nitens and Amblyomma cajennense over a 2-year period. Free-living stages of A. nitens were used to evaluate the influence of season of the year on horse resistance.

Experimental & Applied Acarology, 2002
The objective of this study was to evaluate the role of 2,6-dichlorophenol (2,6-DCP) as sex pheromone of Anocentor nitens. Sex pheromones were extracted by submerging 150 female fed for 6 days in hexane (3 ml) for two hours and sonicating them for 15 min. The extract was analyzed by GC-MS employing the Single Ion Monitoring (SIM) method. Identification

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.

Veterinary Parasitology, 1999
An understanding of seasonal dynamics in the free-living phase of the tropical horse tick, Anocentor nitens, is vital for effective control measures. This study examines seasonal changes in the oviposition and incubation periods, eclosion rates, reproductive success, and larval survival in the free-living phase during the period June 1995-July 1997 ...

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.

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
