Ventral apodemes I forming Y-shaped structure with anterior median apodeme a conspicious transverse band crossing the thorax in front of the scutellumnot joining transverse apodeme. Once mated, the female mites leave the tracheae, moving to the external surface of the bee to locate a new bee and begin the reproductive cycle again.

Workers and drones disperse them when moving from hive to hive; the mite is dispersed through entire apiaries or from one apiary to another Woodward and Quinn, acarais Once in a hive, the mites can move quickly through a colony via bee-to-bee contact. More than a hundred mites can populate the tracheae and weaken the bees. Organic chemical treatments that contain thymol gel or formic acid are also widely used to control Tracheal mite and have been shown to be highly effective in overseas countries.
