Abstract

The appearance of the lumena from the prothoracic tracheae of healthy bees was in dramatic contrast to those infested by Acarapis woodi. The prothoracic tracheal lumena from healthy bees were empty, whereas those from infested bees were filled with unidentified debris and numerous tracheal mites. The outer membrane of the infested trachea appc;ared to be very brittle, and the surface of the cuticular intima within the trachea, was often obscured by a thick layer of material which was not observed in the tracheae of healthy bees. Numerous porous, round globules were also within the tracheae, together with the mites themselves, often completely blocking some of the smaller tracheal branches.
