The aim of this study was to determine the frequency of fascioliasis in cattle and its associated factors, as well as the frequency of infection with larval stages in Lymnaeidae snails in the livestock area of the Huanca district in Arequipa, Peru. In total, 179 samples of bovine, ovine and equine faeces, and 561 Lymnaeidae snails were collected. The associated factors were determined by applying an epidemiological survey for each livestock species, through the interview with the owners. Fasciola hepatica eggs obtained from faecal samples were analysed using the modified four-sieve technique. The snails (n = 484) were crushed on slides to release and analyse the larval stages of the trematode, while 77 snails were processed using the Pointier technique for taxonomic identification. The frequency of Fasciola hepatica in cattle was 46.4%, being higher in sheep and horses, in animals that w...

The species richness and composition of nocturnal parasitoid wasps Ophioninae subfamily in the Arequipa department was determined. Sixteen localities were evaluated along an altitude gradient that goes from sea level up to 4300 m; in each locality, collections were done in March and May 2018. Light traps were used for the evaluation. A total of 15 morphospecies and 8 species corresponding to the genera: Alophophion, Enicospilus, Eremotylus, and Ophion were registered. The highest richness of Ophioninae was found at 3300 m (S = 8). The genera Alophophion and Ophion were more abundant at medium to high elevations, Enicospilus was more abundant at low altitude localities, and Eremotylus was only recorded in a medium altitude locality.

Se determinó la riqueza y composición de especies de avispas parasitoides nocturnas de la subfamilia Ophioninae en el departamento de Arequipa. Se evaluaron 16 localidades, a lo largo de un gradiente altitudinal que va desde el nivel del mar hasta los 4300 m; en cada localidad se realizaron colectas en los meses de marzo y mayo del 2018. Para la evaluación se emplearon trampas de luz. Se registraron 8 especies y 15 morfoespecies correspondientes a los géneros: Alophophion, Enicospilus, Eremotylus y Ophion. La mayor riqueza de Ophioninae se encontró a 3300 m (S = 8). Los géneros Alophophion y Ophion fueron más abundantes en las localidades sobre los 2000 m, Enicospilus fue más abundante en las localidades que se encontraban por debajo de los 1000 m, y Eremotylus solo se registró en una localidad a los 2300 m.
