SYNOPSIS. The development of Babesia caballi (Nuttall) in Dermacentor nitens Neumann was studied in smear preparations and histologic sections of ticks infected with this protozoan parasite. A majority of the parasites in equine erythrocytes ingested by the adult ticks apparently were destroyed.

The objective of this study was to standardize a stall-trial methodology for horses in order to evaluate the pharmacokinetics and efficacy of a 1 % fipronil pour-on formulation against Dermacentor nitens. Brazilian pony breed horses were housed in individual stalls within a covered barn and artificially infested with D.

The aim of this study was to assess the acaricidal activity of hydroethanolic formulations of thymol at varying concentrations on Rhipicephalus sanguineus and Dermacentor nitens larvae. The larval packet test was used and the thymol concentrations tested were 2.5, 5.0, 10.0, 15.0 and 20.0 mg/ml.

We evaluated the acaricidal activity of Acmella oleracea methanol extract and spilanthol on Rhipicephalus microplus and Dermacentor nitens. The extract was made through maceration with methanol. From this extract, a dichloromethane fraction with 99% spilanthol was obtained and tested on R. microplus larvae and engorged females and D. nitens larvae. For

Systematic and Applied Acarology
Of the 44 species within the genus Dermacentor (Acari: Ixodidae) worldwide, nine are found in the Neotropics and four are endemic to this region. In Colombia, located in the northwestern corner of South America, there are two species of the genus: Dermacentor imitans restricted to the trans-Andean Pacific region, and Dermacentor nitens widely ...
