The alarm pheromone was isolated from Carpoglyphus lactis through the bioassay against the mold mite, Tyrophagus putrescentiae, and the compound was identified to be citral, (E and Z)-3,7-dimethylocta-2,6-dienal. The occurence of citral in three other related species, Aleuroglyphus ovatus, Lardoglyphus konoi and Dermatophagoides farinae were also chromatographically demonstrated.
