Since at the beginning of the examinations no specimens of Acarapis 

 woodi had been seen by any of the workers in the United States, there 

 existed some fear that they might in some way be overlooked. 

 Through the court esy of Prof. John Anderson, lecturer in beekeeping. 

 University of Aberdeen, Scotland, two lots of bees suffering from the 

 Isle of Wight disease were received and it was found that no difficulty 

 exists in finding the mites when they are present. Xot only are the 

 mites themselves easily found on examining the tracheal tubes of the 

 thorax, but the tracheal tubes are so discolored (as described by 

 Rennie) as to make the detection of the infestation easy. 



While negative results on only 200 samples do not prove the 

 absence of the mite in the United States, the wide distribution of the 

 samples received and the apparent absence of any serious adult bee 

 disease indicate that the Isle of Wight disease does not exist within 

 the limits of the United States. Statements regarding supposed 

 cases of Isle of Wight disease have appeared in American bee journals 

 from time to time, but there is nothing to support these diagnoses 

 and such statements may be safely disregarded. It is desirable that- 

 further examinations be made as material is available. 



Introduction through queen-mailing cages. — The shipments made by 

 Prof. Anderson brought to light a fact of great importance. In the
