Resumo O estudo teve como objetivo identificar espécies de carrapatos presentes no ambiente e entre animais de cativeiro em Mangaratiba, Rio de Janeiro, Brasil. Os carrapatos foram removidos manualmente de animais de cativeiro e no ambiente usando a técnica de arrasto em flanela. Um total de 91 carrapatos foram capturados (51 adultos, 25 ninfas e 15 larvas). Os espécimes foram identificados morfologicamente como Amblyomma sp., Amblyomma dubitatum, Amblyomma ovale e Amblyomma sculptum, e foram distribuídos entre cinco espécies de mamíferos nativos e uma ave exótica. Este estudo também relata o primeiro caso de infestação do emu australiano (Dromaius novaehollandiae) por A. sculptum .

Abstract The study aimed to identify species of ticks present in the environment and among captive animals, in Mangaratiba, Rio de Janeiro, Brazil. Ticks were isolated from captive animals by manual examination and free-living ticks in the environment were captured using the flannel drag technique. A total of 91 ticks were obtained (51 adults, 25 nymphs and 15 larvae). The specimens were identified morphologically as Amblyomma sp., Amblyomma dubitatum, Amblyomma ovale and Amblyomma sculptum , and were distributed among five species of native mammals and an exotic bird. This study also reports the first case of infestation of the Australian emu (Dromaius novaehollandiae) by A. sculptum.

ABSTRACT The aim of this research was to monitor the presence of females of Aedes aegypti (Linnaeus, 1762) on the Seropédica municipality, Rio de Janeiro State, from 2010 to 2013. For this purpose, the Intelligent Dengue Monitoring (IM-Dengue) and Intelligent Virus Monitoring (IM-Virus) developed by Universidade Federal de Minas Gerais (Ecovec – Minas Gerais, Brazil), were used. IM-Dengue is a tool that allows achieving a weekly overview of A. aegypti infestation, while IM-Virus is another tool that allows detecting dengue virus directly from the mosquito, by Real Time-PCR. Both tools were developed for diagnosis in a prepathogenesis period of the disease, before infection occurrence. Traps were distributed in 19 locations inside the municipality and the bugs were collected weekly during the years of the research. As a result, the presence of 163 females of A. aegypti was recorded over the period; there was no circulation of the virus in the municipality. In one of the 19 study sites, a high degree of disease transmission risk was verified. The study concluded that the municipality, as a whole, showed no risk of disease transmission throughout the field research period.

A pesquisa foi desenvolvida no Laboratório de Zoologia da Universidade Federal Rural do Rio de Janeiro e Setor de Parasitologia Animal da Universidade Estadual do Norte Fluminense Darcy Ribeiro, estado do Rio de Janeiro, no período de 2011 a 2012. O objetivo foi testar in vitro e in vivo a eficácia da planta medicinal Chenopodium ambrosioides Linnaeus, 1786 (erva-de-santa-maria), nas formas fitoterápica e homeopática, como meios alternativos para o controle de endoparasitos de Gallus gallus Linnaeus, 1758 (galinha caipira), um sério problema que afeta a criação e desempenho de aves domésticas, ocasionando morte quando muito intenso, retardo de crescimento, redução do índice de conversão alimentar e aumento na suscetibilidade às doenças infecciosas. As metodologias utilizadas foram preconizadas por Coles et al. (1992), creditada pela World Association for the Advancement of Veterinary Parasitology (WAAVP). O ensaio in vitro demonstrou alta taxa de redução na inibição de eclosão de ovos (97,18%), e o ensaio in vivo, elevada taxa na redução da contagem de ovos nas fezes (91,67%). A pesquisa evidenciou a presença dos gêneros Ascaridia (35,00%), Capillaria (30,00%), Heterakis (25,00%) e Strongyloides (10,00%). C. ambrosioides mostrou em certos momentos superioridade frente ao produto tradicional (Thiabendazole/Mebendazole) e índices superiores aos preconizados pelo Ministério da Agricultura do Brasil e Organização Mundial da Saúde como indicativos de eficácia.

The present survey was carried out at Zoology Laboratory, Universidade Federal Rural do Rio de Janeiro, and Animal Parasitology Sector, Universidade Estadual do Norte Fluminense Darcy Ribeiro, Rio de Janeiro state, from 2011 to 2012. The aim was to test in vitro and in vivo the effectiveness of the medicinal plant Chenopodium ambrosioides Linnaeus, 1786 (santa maria herb) regarding phytotherapeutic and homeopathic alternative methods to control endoparasites of Gallus gallus Linnaeus, 1758 (free range chicken), a serious problem affecting domestic poultry performance causing losses, retarded development, decreased food conversion rate and increase of susceptibility to infectious diseases. In vitro essay demonstrated high reduction rate on eggs eclosion inhibition (97.18%), and in vivo essay showed high fecal eggs counting reduction rate (91.67%). Presence of the genera Ascaridia (35.00%), Capillaria (30.00%), Heterakis (25.00%) and Strongyloides (10.00%) was displayed by this survey. The plant C. ambrosioides showed upper rates front traditional products (Thiabendalol/Mebendazol) as well as to those ones advocated by the Brazilian Ministry of Agriculture and the World Health Organization as effective.

Vinte e sete espécies de dípteros caliptrados (Muscidae e Sarcophagidae) foram capturados no período de dezembro de 1993 a novembro de 1994, com armadilhas orientadas pelo vento (W.O.T.) contendo isca de fígado em putrefação, no jardim zoológico da cidade do Rio de Janeiro. As espécies capturadas em maior abundância foram Musca domestica (57,84%), Peckia chrysostoma (28,16%), Ophyra aenescens (17,11%), Oxysarcodexia thornax (17,82%), Synthesiomyia nudiseta (13,05%) e Oxysarcodexia diana (14,52%).

Twenty-seven species of calyptrate muscoids (Muscidae and Sarcophagidae) were collected from December 1993 to November 1994 with wind oriented traps (W.O.T.) baited with decomposing beef liver at the Rio de Janeiro Zoo. The most abundant species found were Musca domestica (57.84%), Peckia chrysostoma (28.16%), Ophyra aenescens (17.11%), Oxysarcodexia thornax (17.82%), Synthesiomyia nudiseta (13.05%), and Oxysarcodexia diana (14.52%).
