| Studies were carried out on the relationship between feather mites in wild birds captured by mist nets at the Engenho Independência, county of Vicência. The captures were performed in June, September and December (1995) and March (1996). Mites belonging to the families: Analgidae, Psoroptoididae, Avenzoariidae, Proctophyllodidae e Trouessartiidae were identified to genera. The most representative genera, according to the number of hosts they were found were Pterodectes sp. (Proctophyllodidae), with eighteen and Trouessartia sp. (Trouessartiidae), with sixteen hosts, respectively. The Psoroptoididae and Avenzoariidae families were found in only one host each. The ventral face of remiges and rectrices were the main sites inhabited by mites. |

| ABSTRACT Poultry red mite Dermanyssus gallinae is a cosmopolitan and hematophagous species commonly found in layer houses around the world. Poultry mite infestations may cause anemia, stress, low body weight and egg production, and mortality. Mite control is typically based on chemical products, but they are not effective and leave residues in eggs; therefore, alternative control methods, such as entomopathogenic fungi, need to researched. This study aimed at evaluating, in the laboratory, the activity of Brazilian isolates of entomopathogenic fungi against D. gallinae. The mites were collected from a commercial layer house and were sprayed with conidial suspensions (1 × 108 conidia/mL) of five isolates of Beauveria bassiana and Metarhizium anisopliae. All... |

| The assemblage of arthropods and helminths, present in sigmodontine rodents (Cricetidae) from a broad wetland area of the Río de la Plata, Argentina, was studied. A total of 250 sigmodontines were captured during a two-year sampling period: Scapteromys aquaticus and Oxymycterus rufus were the most abundant hosts, followed by Oligoryzomys nigripes, Akodon azarae, Oligoryzomys flavescens, and Deltamys kempi. There were 33102 parasites collected, corresponding with Rhopalopsyllidae fleas (Siphonaptera), Hoplopleuridae lice (Phtiraptera), Laelapidae and Macronyssidae mites, Ixodidae ticks, and Trombiculidae chiggers (Acari), the trematodes Echinostomidae, Microphallidae, and Dicrocoelidae, the flatworm Ciclophyllidea, the nematods Trichuridae, Spiruridae,... |

| El impacto nocivo producido por Caligus rogercresseyi en los centros de cultivo de salmónidos en el sur de Chile ha ido en aumento, por lo que es necesario tener un mejor conocimiento de la especie para poder combatirla haciendo énfasis en la etapa infectante de ésta, el estadío copepodito. Este estudio aporta conocimientos biológicos y conductuales de éste estadío frente al estímulo de tres especies de hospederos; Salmo salar, especie de cultivo, y Eleginops maclovinus e Hypsoblennius sordidus, ambas especies nativas. Se realizaron tres experimentos, dos de ellos basados en los estímulos atractantes emanados del pez hospedero, controlados mediante la formación del filamento frontal de adhesión y respuestas conductuales frente a este estímulo mediante un... |

| Bat flies were surveyed between March, 2007 and February, 2008, in the Carnijó Private Natural Heritage Reserve (08° 07′ S and 35° 05′ W), an area of Atlantic Rainforest in the municipality of Moreno, in the Brazilian state of Pernambuco. Bats were captured biweekly using mist nets set during six hours each night. The ectoparasites were collected with tweezers and/or a brush wet in ethanol and stored in 70% ethanol. The specimens are deposited in the zoological reference collection of the Federal University of Mato Grosso do Sul. Sixteen species of streblid bat flies were collected from 10 bat species of the family Phyllostomidae. Thirteen of the these streblid species were recorded for the first time in Pernambuco. |

| Abstract Abstract: The aim of this study was to investigate the community of metazoan parasites in Hemibrycon surinamensis from the Matapi River, State of Amapá, Brazil. Among the 31 examined fish, 77.4 % were parasitized by Jainus hexops, Tereancistrum ornatus (Monogenea), Contracaecum sp. (Nematoda), Clinostomus marginatum and Posthodiplostomum sp. (Digenea). However, the dominance was of monogeneans J. hexops and T. ornatus, and among the endoparasites, the predominance was of species at the larval stage. The parasites showed random dispersion. Brillouin diversity index varied from 0 to 0.9, evenness from 0 to 0.7 and species richness from 0 to 3 parasites per host. Low levels of parasitic infection were observed and discussed. The results indicate that... |

| ABSTRACT The community composition of parasites was characterized in Astronotus ocellatus from a tributary of the Amazon River, northern Brazil. The prevalence was 87.9%, and a total of 526,052 parasites were collected, with a mean of 15,941 parasites per host. Nine taxa of ecto- and endo-parasites were identified, but Ichthyophthirius multifiliis was the dominant species, while Piscinoodinium pillulare, Clinostomum marginatum and Argulus multicolor were the least prevalent parasites. The parasite community was characterized by a low species richness, low diversity and low evenness. Host body size was not found to influence the composition of the parasite community, and there was no significant correlation between abundance of any parasite species and host... |

| Em um fragmento de mata na área urbana de Juiz de Fora (MG) foram capturados 15 quatis com armadilha e ceva, para estudo dos seus ectoparasitos. Outros quatro animais, atropelados no entorno, foram também examinados imediatamente após o atropelamento, e incluídos na análise. Os ectoparasitos foram removidos com a utilização de pinça e pente-fino e acondicionados em etanol 70°GL. Pulgas e piolhos foram clarificados e montados para análise em microscopia. Os ixodídeos foram identificados sob estereoscopia. Não foram encontrados carrapatos adultos. Larvas e ninfas de carrapatos foram encontradas, respectivamente, em 36,8% e 63,1% dos hospedeiros examinados. Ninfas que sofreram muda foram identificadas como Amblyomma cajenennse. A espécie de piolho... |

| Bomolochidae Claus, 1875 is a copepod family with worldwide distribution that parasitizes marine fishes. This study provides the first report of Hamaticolax scutigerulus (Wilson, 1935) (Copepoda: Bomolochidae) in the spotted goatfish Pseudupeneus maculatus (Bloch, 1793), in the coastal waters of Pernambuco, northeastern Brazil. Prevalence of 35%, mean intensity of infestation of 1.9±1.3 and mean abundance of 0.7±1.2 were found. The setae and spines of the leg armor of the Hamaticolax species were analyzed to identify the present species. |

| This study aimed to describe the diversity of fish parasites in the Amambai River, in the Mato Grosso do Sul State, and generate information to facilitate studies of the biotic integrity of the region. During the period of September 2015 and July 2015, 48 specimens of 11 species of fish were analyzed for parasites. A total of 56.25% of the fish sampled from the Amambai River were infected with one or more metazoan species. A total of 21,514 parasite specimens belonging to 24 different species we found; they were distributed among six groups: Acanthocephala (Neoechinorhynchida), Cestoda (Proteocephalidea), Crustacea (Ergasilidae), Digenea (Cladorchiidae, Dadaytrema), Monogenea (Dactylogyridae) and Nematoda (Atractidae, Cucullanidae, Camallanidae,... |

| ABSTRACT Parasites are important components of communities and constitute great part of the biological diversity found in ecosystems, providing valuable information about their hosts and the environment in which they live. However, despite its importance, parasitic diversity is still not well known in some regions of Brazil, especially with respect to fish parasites in the Northeast Region. The present study aims to perform the survey of gill parasites of fish from two tropical estuaries located in northeastern Brazil: Paraíba and Mamanguape rivers. Two collections were made in each estuary, one during the dry period (November / 2013) and the other during the rainy season (July / 2014). The fish were caught using a beach seine net, dragged along the main... |

| Host-parasite interactions between crustaceans and six fish species (Psectrogaster falcata, Ageneiosus ucayalensis, Acestrorhynchus falcirostris, Hemiodus unimaculatus, Serrasalmus gibbus and Geophagus proximus) from a reservoir in eastern Amazon, northern Brazil, were investigated. Eight hundred and seventy-eight parasites belonging to three crustacean species, Excorallana berbicensis, Argulus chicomendesi and Ergasilus turucuyus, which parasitized the hosts’ mouth, gills and tegument, were collected from 295 fish and examined. High infestation levels were caused by E. berbicensis on the body surface of the hosts. Excorallana berbicensis showed aggregate dispersion, except in S. gibbus, while E. turucuyus showed random dispersion in A. falcirostris. The... |
