PARASITISM OF WILD GOULDIAN FINCHES (ERYTHRURA GOULDIAE) BY THE AIR-SAC MITE STERNOSTOMA TRACHEACOLUM

Abstract
,Sixty-two,percent,of,26 wild,caught,Gouldian,finches,(Erythrura,gouldlae),were infected with Sternostoma tracheacolum, a parasitic rhinonyssid mite. The intensity of infection was higher in adult finches than juveniles, and higher in juvenile females than juvenile males. Histopathological,investigation,of wild,Gouldian,Finches,revealed,bronchopneumonia,and,air sacculitis,associated,with,mite,infection.,Although,this,mite,may,not,have,contributed,to,the decline,of,Gouldian,finch,populations,in,the,wild,during,the,past,20 yr. it may,be suppressing the return,of the finch to its former,status. Key words: Gouldian finch, respiratory parasite, air-sac mite, Erythrura gouldlae, Sternostoma tracheacolum, disease, air sacculitis.
