Pheromone study on acarid mites II Presence of the alarm pheromone in the mold mite, Tyrophagus putrescentiae (Schrank) (Acarina : Acaridae) and the site of its production

Abstract

As the alarm pheromone of the mold mite, Tyrophagus putrescentiae (Schrank), neryl formate, (Z)-3,7-dimethylocta-2,6-dien-1-ol formate, was emitted or discharged from a pair of their latero-abdominal gland (or of oil gland) to the environment and air-borne-ly stimulated surrounding mites to escape. These evidences were demonstrated.
