| Eight wild fowls kept in captivity at a Brazilian Zoo were examined from july 1994 to October 2000. One hundred twenty-three Ixodidae specimens were collected and sent to the Ixodides Laboratory at the Instituto Oswaldo Cruz, Rio de Janeiro, Brazil. They were examined by stereomicroscopy and were identified as Amblyomma longirostre (53), A. pacae (50), A. cajennense (14), and A. parvum (6). |

| Durante 24 meses foram capturados, inspecionados e liberados no mesmo espaço do Parque Estadual da Pedra Branca, Rio de Janeiro, 96 marsupiais e 64 roedores. Neles foram recolhidos manualmente 105 carrapatos, de 10 espécies em duas famílias. A espécie de carrapato dominante entre os roedores foi Amblyomma longirostre e entre os marsupiais foi Ixodes loricatus. Houve correlação direta significativa entre a temperatura e a intensidade de parasitismo por carrapatos. |

| In order to monitor the susceptibility of Boophilus microplus to acaricides and improve control measures, the effects of cypermethrin, deltamethrin and permethrin on larvae obtained in the city of Goiânia in the Brazilian state of Goiás were studied. Although these pyrethroids are already sold as acaricides, their cost-benefit efficiency has been questioned. Fasting 14-21 day-old larvae were immersed in solutions of the acaricides under test, maintained at 27±1° C, and relative humidity over 80%, and observed under the stereoscope within an apparatus originally designed for studying the non-parasitic phase of the tick life cycle. The observed toxicological effects were: excitability, repetitive motion, decreased motor ability, detachment, paralysis,... |

| A topographical and histological study of the male genital accessory gland complex of Boophilus microplus was undertaken. Ten lobes were found, the most prominent of which is the single dorso-median lobe, subdivided into antero-dorsal and postero-dorsal lobes. The other lobes are: a pair of postero-ventral lobes, a pair of lateral lobes (subdivided into dorso-lateral and postero-lateral lobes), a pair of antero-ventral lobes, a single medio-ventral lobe and a pair of latero-ventral lobes. These lobes were observed to present individual topographical and histological characteristics, with independent openings, hence the conclusion is that they form a gland complex. The secretory nature of the dorso-median lobe duct was also analysed. |

| ABSTRACT: Ticks are arthropods that are highly competent in transmitting pathogens to animals and humans. Among these, the genus Amblyomma is the most representative within the Neotropics. Amblyomma longirostre ticks are naturally distributed in countries of South, Central and North America. Their immature stages preferentially parasitize birds (Passeriformes), while adult stages are usually found on rodents. Therefore, reports of this tick species on wild hosts is epidemiologically relevant, especially because of these ticks' potential for transmitting pathogens to other wild and domestic animals, and also to humans. Thus, the aim of this study was to report infestation by Amblyomma longirostre on Cyanocompsa brissonii in southern Brazil. |

| This study assesses the weight gain of partially engorged Rhipicephalus sanguineus females that were artificially fed via capillary tubes and the influence of capillary tube feeding on the biological parameters of the non-parasitic stage of the species. The ticks were sorted into four groups, each containing ten females of a homogeneous weight. The groups were each treated for different feeding times, 2, 6, 12 and 24 hours. The weight gain of the artificially fed females was measured, and the biological parameters of the non-parasitic stage of the tick were observed for each treatment group. The statistical non-parametrical Dunn and Kruskal-Wallis tests were used to compare the results. The mean weights (mg) were 0.2±2.4; 4.3±5.8; 7.4±5.8 and 12.0±11.2 for... |

| Abstract Ticks represent a large group of pathogen vectors that blood feed on a diversity of hosts. In the Americas, the Ixodidae ticks Amblyomma cajennense are responsible for severe impact on livestock and public health. In the present work, we present the isolation and molecular identification of a group of culturable bacteria associated with A. cajennense eggs from females sampled in distinct geographical sites in southeastern Brazil. Additional comparative analysis of the culturable bacteria from Anocentor nitens, Rhipicephalus sanguineus and Ixodes scapularis tick eggs were also performed. 16S rRNA gene sequence analyses identified 17 different bacterial types identified as Serratia marcescens, Stenotrophomonas maltophilia, Pseudomonas fluorescens,... |

| ABSTRACT This is a commented list of tick’s species collected on various wild and domestic animals, including the reports on scientific literature for the studied region. Most of animals were small or medium mammals. Carnivores were the main taxa group examined. Although, the pampas deer ( Ozotocerus bezoarticus) and giant anteater ( Mymercophaga tridactyla) also has a good representation on study. Among domestic animals, dogs, horses and cattle were examined. Summing up, 18 tick species were listed for the region. Sixteen were hard ticks (Ixodidae) and two soft ticks (Argasidae). Amblyomma sculptum was the most common and abundant hard tick. Ornithodoros rostratus (Argasidae) was very abundant, being the more important Argasidae tick on the study region.... |

| Se estudiaron las garrapatas (Acari: Ixodidae) de perros en ambientes urbanos, periurbanos y rurales de la provincia de Corrientes por medio de colecciones mensuales durante un año en siete sitios diferentes. De los 138 perros examinados, en 87 (63,04%) se determinaron tres especies de garrapatas: Amblyomma tigrinum (n=35), Amblyomma ovale (n=2) y Rhipicephalus sanguineus sensu lato (n=523). Las mayores prevalencias para A. tigrinum y R. sanguineus s.l. fueron halladas en ambientes rurales. Especímenes de R. sanguineus s.l. fueron detectados a lo largo de todo el año, con picos de abundancia en primavera y verano, A. tigrinum fue encontrada en otoño, invierno y primavera con un pico en esta última estación, mientras que A. ovale fue colectada sólo en... |

| There are only 33 records of rodents of the subfamily Caviinae Fischer de Waldheim, 1817 (Hystricognathi: Caviidae) infested by hard ticks in South America, where the subfamily is established. Caviinae is formed by three genera: Cavia Pallas, 1766, Galea Meyen, 1833 and Microcavia Gervais and Ameghino, 1880. Records of Amblyomma pictum Neumann, 1906, A. dissimile Koch, 1844 and A. pseudoparvum Guglielmone, Keirans and Mangold, 1990 are considered doubtful. Bona fide records are all for localities south of the Amazonian basin in Argentina, Bolivia, Uruguay and Brazil. Thirteen records are for A. tigrinum Koch, 1844, four for A. triste Koch, 1844, three for A. parvum Aragão, 1908 (larvae and nymphs of these three species), one for A. cajennense (Fabricius,... |

| We studied the ecology of ticks found in different species of a taxocenosis of snakes from the Serra do Mendanha, an area of Atlantic Rainforest located in the state of Rio de Janeiro, southeastern Brazil. Snakes were sampled monthly in the field during a period of 48 months. The specific identity of the hosts and their parasites, the number of parasites, and and snout-vent length and body mass of each host were recorded. A total of 25% of the species of snakes in the area were parasitized by ticks (larvae, nymphs and adult females) Amblyomma rotundatum Koch, 1844 was the predominant parasite species. The infestation parameters varied among the species of snakes sampled, with the highest prevalence of A. rotundatum being observed in the viperid Bothrops... |
