An alarm pheromone was isolated from Carpoglyphus lactis (L.) by bioassay with Tyrophagus putrescentiae (Schr.); it was found to be citral (3,7-dimethylocta-2,6-dienal). The presence of citral in 3 related species of mites Aleuroglyphus ovatus (Troup.) Lardoglyphus konoi (Sasa & Asanuma) and Dermatophagoides farinae Hughes was also demonstrated by chromatographic techniques. Citral showed activity as an alarm pheromone in both C. lactis and L. konoi.
