In a recent ecological study of the ticks on animal trails within an area Atlantic rainforest in south–eastern Brazil, Amblyomma aureolatum, A. brasiliense, incisum, ovale and Haemaphysalis juxtakochi were found questing vegetation. Most recorded by small, man-made dam forest border dubitatum but few brasiliense cajennense, one incisum H. also found. The seasonal activity indicated that had generation/year.On trails, most tick species stages quested vegetation at height 30–40 cm above ground...
The control of tick species that affect animal production is vital for the economic welfare cattle industry. This study focused on testing acaricidal activity essential oil from leaves and stems Tagetes minuta against several Brazilian species, including Rhipicephalus (Boophilus) microplus, sanguineus, Amblyomma cajennense Argas miniatus. chemical composition was determined by chromatography spectroscopy analyses, which revealed presence monoterpenes. adult immersion test (AIT) larval packet...
The Rhipicephalus (Boophilus) microplus tick is responsible for considerable economic losses in Brazil, causing leather damage, weight loss and reduced milk production cattle results the transmission of pathogens. Currently, main method controlling this using acaricides, but their indiscriminate use one major causes resistance dissemination. In study, adult immersion test (AIT) was used to evaluate ticks from 28 properties located five different states (Mato Grosso do Sul, Mato Grosso,...
Rondonia state reports more spotted fever (SF) cases than any other in the Brazilian Amazon. Ariquemes is only municipality that has reported SF this state, but no information been obtained about tick and Rickettsia spp. responsible. This study aimed to describe free-living fauna search for rickettsial DNA ticks collected from a region where one specific infection was most likely acquired. Ticks were at four sites municipality, site both Alto Paraíso Rio Crespo municipalities. A total of...
Hazardous polycyclic aromatic hydrocarbons (PAHs) widely occur in the environment and are believed to be mainly anthropogenic. Here we present strong indications for large biological sources of PAHs naphthalene, perylene, possibly also phenanthrene Amazonian basin. Termite nests, plant wood, soils were sampled. Naphthalene is detected wood accumulated nests termites from genus Nasutitermes. Perylene found all studied termite including six different genera. Phenanthrene occurs at substantial...
Sex and recombination are central processes in life generating genetic diversity. Organisms that rely on asexual propagation risk extinction due to the loss of diversity inability adapt changing environmental conditions. The fungus-growing ant species Mycocepurus smithii was thought be obligately because only parthenogenetic populations have been collected from widely separated geographic localities. Nonetheless, M. is ecologically successful, with most extensive distribution highest...
The Rhipicephalus (Boophilus) microplus complex currently consists of five taxa, namely R. australis, annulatus, (B.) clade A sensu, B and C sensu. Mitochondrial DNA-based methods help taxonomists when they are facing the morpho-taxonomic problem distinguishing members complex. purpose this study was to perform molecular characterization ticks in all regions Brazil infer their phylogenetic relationships. Molecular analysis characterized 10 haplotypes COX-1 gene. network revealed that...
The objectives of this study were to evaluate the resistance Amblyomma mixtum and Rhipicephalus microplus ticks from co-infested bovines Veracruz region in Mexico different acaricide families demonstrate viability packet test on A. instars. following used: a combination (cypermethrin 15 g + chlorpyrifos 25 citronella 1 butoxide piperonyl g), amidine (formamidine 12.5 pyrethroid organophosphate (dichlorvos 60 20 g). Regarding both species, was found for R. microplus, as efficacy did not...
Tick infestation may cause several problems including affecting domestic animal health and reducing the production of meat milk, among others. Resistance to classes acaricides have been reported, forcing researchers search for alternative measures, such as vaccines against ticks, ensure tick control while having no or at least low negative impacts on environment public health. However, current commercially available in different strains Rhipicephalus microplus are reported be efficacy....
Among cattle, Bos taurus breeds and their crosses are more sensitive to tick infestations than indicus that resistant infestation adaptable tropical climates. The presence of susceptible individuals in herds inadequate control lead direct indirect losses the meat production chain, addition increased mortality due cattle fever. objective this study was describe, compare rank sensitivity different stabled Rhipicephalus microplus present, as an innovative result, a scale called Tick Ruler....
Identifying the tick species that successfully feed on humans would increase knowledge of epidemiology several tick-borne diseases. These salivate into host, increasing risk pathogen transmission. However, there is a lack data in literature regarding ticks prefer to humans. Herein, we describe successful feeding Amblyomma coelebs Neumann nymphs two authors after accidental bites occurred during field surveys preserved areas Mato Grosso do Sul, Brazil. One host–parasite interactions was...
The success of cattle tick fixation largely depends on the secretion substances that alter immune response host. majority these are expressed by parasite salivary gland and secreted in saliva. It is known hosts can mount responses against ticks bovine European breeds, industrial crossbreeds more susceptible to infestations than Bos indicus cattle. To identify candidates for development novel control strategies Rhipicephalus (Boophilus) microplus, a transcriptome analysis engorged females fed...
The present work aimed to verify the penetration pattern of Metarhizium anisopliae fungus into Rhipicephalus sanguineus tick eggs, as well lesions occurred inside egg. adherence and were studied by scanning electron microscopy action in internal tissues was evaluated through conventional histological sessions. For observation these events, experimental infections performed 11 groups R. eggs containing 25 mg each. bathed during 3 minutes under manual shaking a 10(8) conidia/mL suspension....
The control of ticks with vaccines is global interest. Experimental incorporate new technologies as soon they are available. Historically, the main vaccine studies have focused on one-host cattle tick Rhipicephalus microplus, and efficacy evaluations been standardised for this species. On other hand, candidates three-host being done somewhat arbitrarily thus comparisons within current literature vaccines, well methods control, difficult. We herein provide a formula evaluation designed...
