Ação do fungo Beauveria bassiana (Balsamo) Vuillemin, 1912 sobre a fase parasitária do carrapato Anocentor nitens (Neumann, 1897) Schulze, 1937 (Acari: ixodidae) [PDF]
Ciencia Rural, 2003 A patogenicidade do fungo Beauveria bassiana (isolado 986) foi avaliada no desenvolvimento da fase parasitária do Anocentor nitens, acompanhando o desenvolvimento de larvas não alimentadas até o estágio adulto. Foram utilizados dois tratamentos e um grupo controle com cinco repetições cada.

A Encephalitozoon-like microsporidia was found in epithelial cells of the midgut and the salivary glands of Amblyomma cajennense (F.) and Anocentor nitens (Neumann) that had fed on rabbits. Ultrastructural studies demonstrated that all stages of the life cycle of the parasite occur in parasitophorous vacuoles and contain only 1 nucleus.

Ação do fungo Beauveria bassiana associado a gel polimerizado de celulose no controle do carrapato Anocentor nitens em teste de campo [PDF]
Arquivo Brasileiro De Medicina Veterinaria E Zootecnia, 2009 Foram selecionados 20 equídeos naturalmente infestados por Anocentor nitens, dos quais seus pavilhões auriculares foram submetidos a quatro tratamentos distintos: gel associado a Beauveria bassiana, apenas gel, apenas B. bassiana e um grupo-controle.

Journal of Invertebrate Pathology, 2006
The present paper reports the occurrence of natural co-infection of Babesia caballi and Encephalitozoon-like microsporidia in the tick Anocentor nitens. Engorged females of ticks, collected from a naturally B. caballi-infected horse, were incubated at 27 degrees C and relative humidity over 83%.

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.

Seasonal dynamics of Anocentor nitens on horses in Brazil
Veterinary Parasitology, 2000Anocentor nitens is a widespread ectoparasite of horses in Brazil. A study of the seasonal dynamics of the parasitic phase of this tick was made by regular census of engorging females (>/=4mm) on free-ranging horses, fortnightly from July 1995 to July 1997, at Pedro Leopoldo, Minas Gerais. Twenty horses were divided into four groups of five animals per

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 ...

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

Avaliação do comportamento anômalo de Anocentor nitens (Neumann) (Acari: Ixodidae), durante a fase não parasitária [PDF]
Revista Brasileira De Zoologia, 1993 A new technique was develop to study the anomalous behavior of non parasitic phase of Anocentor nitens on horse host. From the total teleogines was still alive during all experimental period, 89.1% laided eggs on ear host. The eclosion index was 77.05% with 80.0% of eclodibility.The preoviposition period and oviposition period was 3 to 17 days (4.92±0 ...

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 ...
