Compostos bioativos e o controle de carrapatos em bovinos [PDF]

Pubvet, 2015
Opposite the historic parasite resistance phenomenon, especially the Rhipicephalus (Boophilus) microplus, the various synthetic active ingredients available in the market, constant investigations in the search for new molecules effective in controlling ectoparasites are driven, preferably by natural bioactive molecules.

Host–parasite relationship in urban environments: A network analysis of haemoparasite infections in Nasua nasua Linnaeus (South American coati)

Medical and Veterinary Entomology, Volume 39, Issue 3, Page 456-463, September 2025.
Urban environments alter host–parasite dynamics, as seen in Nasua nasua, where haemotropic Mycoplasma plays a key role in parasite spread through frequent social interactions. Network analysis revealed low modularity in interactions between N. nasua and tick‐borne haemoparasites, with functional roles unaffected by biotic factors, tick infestation or ...

Spatial capture‐recapture can improve environmental impact assessments for large carnivores

Ecological Solutions and Evidence, Volume 6, Issue 3, July–September 2025.
Most Environmental Impact Assessments for large carnivores rely on summary statistics or relative abundance indices, all of which ignore imperfect detection and may lead to biased and unreliable conclusions about population status and infrastructure impacts. By applying spatial capture‐recapture (SCR) models to georeferenced genetic data from wolves in

Environmental DNA Template Variation: Its Relevance for Species Detection and Conservation

Freshwater Biology, Volume 70, Issue 3, March 2025.
ABSTRACT Accurate species monitoring is foundational for understanding and assessing species extinction risk. Environmental DNA (eDNA) based species detection methods have been proposed as fast and powerful biodiversity monitoring tools. Yet, these methods are susceptible to errors that might hinder the assessment of species extinction risk.

Evaluation in vitro of the infection times of engorged females of Rhipicephalus (Boophilus) microplus by the entomopathogenic nematode Steinernema glaseri CCA strain Avaliação in vitro dos tempos de infecção de fêmeas ingurgitadas de Rhipicephalus (Boophilus) microplus pelo nematoide entomopatogênico Steinernema glaseri estirpe CCA

Ciência Rural, 2010
Studies have shown that ticks are susceptible to infection by entomopathogenic nematodes. These studies indicate different susceptibilities of ticks to infection by these fungi, depending on the tick species, development phase, entomopathogenic nematodes

Potencial de plantas acaricidas no controle de carrapatos Rhipicephalus (Boophilus) microplus [PDF]

Revista de Ciência Veterinária e Saúde Pública, 2016
Os carrapatos fazem parte do filo dos Artrópodes, pertencem à família Ixodidae, e destacam-se por sua importância toxicológica, através do parasitismo em aves e mamíferos, podendo utilizar o ser humano como hospedeiro. Dentre as espécies que mais causam adversidades, encontra-se a Rhipicephalus (Boophilus) microplus, popularmente conhecido como ...
