Reevaluating the presence of Rhipicephalus australis (Acari: Ixodidae) in Southeast Asia: A phylogenetic approach based on Cambodian tick samples

open access: yesTicks and Tick-Borne Diseases
Morphological variability between Rhipicephalus australis and R. microplus has led to taxonomic ambiguity, leading to species misidentification. Rhipicephalus australis is reported to have a distribution range in Pacific Ocean region extending to several

Plasma Pharmacokinetic Profile of Fipronil 1% Pour‐On in Cattle: Photodegradation and the Sustained Systemic Persistence of Fipronil Sulfone

open access: yesJournal of Veterinary Pharmacology and Therapeutics, Volume 49, Issue 5, Page 515-524, September 2026.
ABSTRACT This study characterized the long‐term pharmacokinetic profile of a 1% fipronil pour‐on formulation in Nellore bulls under field conditions. Seventeen animals received a single topical dose (1 mg/kg), and plasma concentrations of fipronil and its metabolites (sulfone and desulfinyl) were monitored for 175 days using LC–MS/MS.

Rhipicephalus microplus cystatin as a potential cross-protective tick vaccine against Rhipicephalus appendiculatus

open access: yesTicks and Tick-borne Diseases, 2020
Rhipicephalus appendiculatus, the brown ear tick, is an important disease vector of livestock in eastern, central and southern Africa. Rhipicephalus appendiculatus acaricide resistance requires the search for alternative methods for its control. Cystatins constitute a superfamily of cysteine peptidase inhibitors vital for tick blood feeding and ...

Cellular immune response of Amblyomma sculptum and Amblyomma americanum to entomopathogenic fungi: Implications for biological tick control

open access: yesMedical and Veterinary Entomology, Volume 40, Issue 3, Page 582-594, September 2026.
Amblyomma sculptum showed a plasmatocyte‐dominant haemocyte profile. Beauveria bassiana increased plasmatocytes and reduced granulocytes, whereas Metarhizium robertsii did not cause significant changes. Amblyomma americanum showed a granulocyte‐dominant haemocyte profile. Beauveria bassiana reduced total haemocytes and granulocytes. B.

Survival of Theileria parva in its nymphal tick vector Rhipicephalus appendiculatus under laboratory and quasi natural conditions [PDF]

open access: yes, 2003
Groups of nymphal Rhipicephalus appendiculatus Muguga, having a mean of 1 or 9 Theileria parva Muguga-infected salivary gland acini per tick, were kept under quasi-natural conditions at an altitude of 1950 m or 20°C at a relative humidity of 85% in the ...

Host, vector, and parasite dynamics: exploring intrinsic and extrinsic factors shaping tick‐borne filarial nematode transmission

open access: yesBiological Reviews, Volume 101, Issue 4, Page 1779-1792, August 2026.
ABSTRACT Tick‐borne filarial nematodes are a complex and understudied group of parasites that rely on ticks for transmission in vertebrates. This review examines how intrinsic and extrinsic factors may influence the successful transmission of filarial nematodes in tick vectors, drawing insights from extensively studied haematophagous dipteran vector ...

An update on distribution models for Rhipicephalus microplus in West Africa

open access: yesGeospatial health, 2013
The cattle tick, Rhipicephalus microplus, which reached the West African region approximately 8 years ago, has established viable populations in Côte d'Ivoire and Benin and spread rapidly from the assumed points of introduction. However, existing maps of its distribution range do not agree on the areas at risk, most probably due to suboptimal modelling

Small molecules as arthropod kinin receptor antagonists, feeding modulators, or novel mosquitocidal agents

open access: yesPest Management Science, Volume 82, Issue 7, Page 6842-6863, July 2026.
A two‐pronged screen of small molecules – (1) on recombinant kinin receptor and (2) through topical application – identifies kinin receptor antagonists, feeding behavior modulators, and new mosquitocidal molecules. Abstract BACKGROUND Aedes aegypti and Culex quinquefasciatus mosquitoes are primary vectors for numerous human and animal pathogens and ...
