The biological cycle of female ticks of Amblyomma cooperi was studied under controlled conditions. The study has begun with two engorged females collected in a naturally infested wild capybara. The larvae originated from the oviposition of these two females were used for collecting young adults through artificial infestations in rabbits. The female parasitic and free living phases were evaluated using artificial infestation of ticks in a capybara. The average body weight of females was 958.2± 175.6mg, the average pre-egg laying period was 8.5± 1.4 days, the reproductive efficiency index was 59.5± 4.2 and the nutritional efficiency index was 77.3± 4.8. The incubation and eclosion periods were 41.9 and 5.9 days, respectively, and the rate of eclosion was... |

O objetivo deste trabalho foi identificar as espécies de carrapatos observadas sobre capivaras na Estação Ecológica do Taim, Rio Grande- RS, Brasil. Foram examinadas 27 capivaras encontradas mortas por atropelamento na BR 471, em seu trecho que corta a Estação, sendo cole lados 497 carrapatos das espécies Amblyomma cooperi (=A. lutzi; = A. ypisilophorum), Amblyomma triste, Amblyomma tigrinum e ninfas do gênero Amblyomma. A. cooperi representou 68,41% dos carrapatos identificados, com uma freqüência de parasitismo de 92,60% dos hospedeiros, enquanto A. triste representou 24,75% dos carrapatos em 44,43% dos hospedeiros e A. tigrinum foi coletado em 14,81% dos hospedeiros, totalizando 1,21% dos carrapatos. As ninfas de Amblyomma sp. foram cotetadas em 18,51%... |
