New records of the feather mite Pterolichus obtusus Robin, 1877 (Acariformes: Astigmata: Pterolichidae) parasitizing chickens Gallus gallus domesticus (L.) (Galliformes: Phasianidae) in Brazil

Abstract

The feather mite Pterolichus obtusus Robin, 1877 (Astigmata: Pterolichidae) is associated with Gallus gallus domesticus (L.) worldwide. Here, we report new records of this species from rustic chickens in Brazil after a gap of 45 years, and for the first time in a northern area of this country. The major role of Brazil as one of the main chicken meat producers and exporters highlights the importance of these new findings. Knowing and keeping track of the distribution of this ectoparasitic species might offer valuable information for the development of animal health programs and policies aimed at mitigating mite pest infestations, in addition to support decision-making processes regarding research funding to study the damage caused by P. obtusus in domestic and wild fowl populations, contributing to the advancement of aviculture.
