Comparing scapular morphology of Amblyomma sculptum and Amblyomma dubitatum nymphs allows a fast and practical differential diagnosis of ticks in highly infested areas with dominance of these two species

Experimental and Applied Acarology, 2022
Rickettsia rickettsii infection causes the highest human fatality rate among all Rickettsia species of the world and is endemic in Southeast Brazil. In this part of the country most human spotted fever cases are related to unnaturally high populations of ticks, usually a mix of two species, Amblyomma dubitatum Neumann and Amblyomma sculptum Berlese and

HUMAN PARASITISM BY THE CAPYBARA TICK, AMBLYOMMA DUBITATUM (ACARI: IXODIDAE)

Entomological News, 2007
During two field trips in the state of Sao Paulo, two of us became infested by two adults, three nymphs, and one larva of the capybara tick, Amblyomma dubitatum Neumann, 1899 (= Amblyomma cooperi Nuttall and Warbuton, 1908). Previously, there has been only a single report of an A. dubitatum adult tick from humans.

Vector competence and transovarial transmission of Rickettsia rickettsii in Rickettsia bellii-infected and -uninfected Amblyomma dubitatum ticks

Experimental and Applied Acarology
Brazilian spotted fever (BSF) is endemic in southeastern Brazil, where Amblyomma sculptum is the main vector incriminated in the transmission of R. rickettsii to humans. In many BSF-endemic areas capybaras are the main hosts for A. sculptum and also efficient amplifiers of R. rickettsii for this tick species.

Seasonal dynamics and rickettsial infection in free-living Amblyomma dubitatum in the Atlantic forest biome in north-eastern Brazil

Acta Tropica, 2021
The genus Amblyomma is the most representative tick genus in Brazil and some species act as vectors of pathogenic organisms to animals and humans. Information on the seasonal dynamics of Amblyomma spp. as well as on rickettsial organisms infecting these ticks in some regions in Brazil is still fragmentary.

Repellent activity of the non-host semiochemical (E)-2-octenal against Amblyomma sculptum and Amblyomma dubitatum ticks under field conditions

Experimental and Applied Acarology
Amblyomma ticks pose a significant public health threat due to their potential to transmit pathogens associated with rickettsial diseases. (E)-2-octenal, a compound found in donkeys (Equus asinus), exhibits strong repellent properties against Amblyomma sculptum nymphs under laboratory conditions.

Records of the Invasive Cattle Tick Rhipicephalus microplus on Wild Hosts and of a Neotropical Tick, Amblyomma dubitatum, on Invasive Alien Mammals, Southern Brazil

Journal of Wildlife Diseases
Invasive species threaten wildlife. We detected invasive ticks on wildlife and indigenous ticks on invasive mammals in southern Brazil. The invasive cattle tick Rhipicephalus microplus was found on 12 native mammals and one invasive exotic (Axis axis). The Neotropical tick Amblyomma dubitatum was found on three invasive alien mammal species.
