ABSTRACT

Chrysomus ruficapillus (Vieillot, 1819) is an abundant bird of the Pampa Biome, often found associated with Oryza spp. cultivation. One hundred twenty-two birds were collected in rice fields from southern Brazil to examine the presence of helminths. One hundred fourteen C. ruficapillus were positive for at least one parasitic species (P%=93.4). We identified 15 taxa: species of Trematoda (P%=75.4), two Cestodes (P%=20.5), four Nematodes (P%=57.4) and one acanthocephalan (P%=2.4). Results and parasitological indexes are new for C. ruficapillus contributing to parasitological knowledge of species and for the helminthology of Icteridae in South America.

RESUMEN

Chrysomus ruficapillus(Vieillot, 1819) es una ave abundante en Bioma Pampa frecuentemente asociada a arrozales. Se examinaron 122 especímenes recolectados en campos de arroz del extremo sur de Brasil para investigar la presencia de helmintos. Ciento y catorce C. ruficapillus fueron positivos para por lo menos uma espécie parásita (P% = 93.4) y fueron identificados 15 taxa: ocho pertenecientes a Trematoda (P% = 75.4), dos a Cestoda (P% = 20.5), cuatro a Nematoda (P% = 57,4) y uno a Acanthocephala (P% = 2.4). Los resultados y índices parasitológicos son inéditos para C. ruficapillus contribuyendo al conocimiento parasitológico de la espécie y para la helmintología de Icteridae en América del Sur.
