  abstract = {{T}he poultry red mite ({PRM}) is an obligatory haematophagous pest that causes substantial economic losses in poultry worldwide. {T}he {PRM} does not live on the host but in the bird's environment and must find its host remotely. {H}ence, manipulating chicken odours is of interest. {S}everal crude plant-originating volatile organic compounds ({VOC}s) have already been shown as repellent to {D}ermanyssus gallinae. {W}e aimed to test whether these {VOC}s can interfere with {PRM} host-seeking behaviour by their oral administration to the poultry. {T}he objectives were to determine (1) if hen odours are modified by supplemented feed ingestion and (2) if such treatment makes hens less attractive to the {PRM}. {C}hemical characterization by gas chromatography-mass spectrometry of the hen odour was conducted before and after the hens ingested the supplemented feed. {T}he chromatograms obtained show that hen odour was substantially modified after the hens consumed it. {A}mong the molecules recurrently detected from the supplemented hens, 26% were nearly absent in the unsupplemented hens. {B}ehavioural choice tests to compare the effect of the modified and unmodified-host odours on the {PRM} show that some of the plant-originating emitted {VOC}s and the modified whole-hen odours were repellent to the {PRM}.},
