Аннотация
Megninia ginglymura (Mégnin) (Acari: Analgidae) is a widely distributed feather mite species. In South America, ectoparasitism have been documented in laying hens in Venezuela and Brazil, with records in the latter country from the states of Ceará, Paraíba, Minas Gerais, São Paulo, Rio de Janeiro, and Rio Grande do Sul. Between March and June 2024, were examined, monthly, feathers from Automated Vertical Climate System (AVC), Automated Vertical System (AVS) and Automated Californian System (SIG) in the northeastern region of the state of Pará, Brazil, in the Amazon biome. Megninia ginglymura were found on the feathers during the sampling period. Greater mite abundance was observed in abdomen, in the SIG and AVS, and in the cloaca, in AVC. Higher abundance of eggs was observed on the inner part of the wings, in the systems.
