3.3. Detection methods

Since these parasitic mites reside inside the tracheae, their detection requires specialized techniques, such as thoracic disc preparation and examination under a dissecting microscope.  This is a laborious procedure. Molecular techniques are currently being developed (see section 3.4.3.) for processing bees in bulk, and should provide increased sensitivity, specificity and speed of screening bees for tracheal mites.
