The Occurrence of Diseases of Adult Bees, II. 11 



The bees recorded as coming from Italy consisted of two lots of 

 worker bees which had accompanied queenbees, one lot having been 

 shipped in 1921. The specimens from Carniola were all lots ol 

 workers from mailing cages, the shipments being made early in 1922. 

 During 1922 specimens were received from 36 States, Canada, Italy, 

 and Carniola, and during 1921 and 1922 specimens have been re- 

 ceived from 44 States and from 4 foreign countries. No cases of Isle 

 of Wight disease have been seen in this work except the cases from 

 Scotland discussed in the earlier publication (46). 



THE DOMINION OP CANADA. 



Following the discussion of the apparent freedom of the United 

 States and the Dominion of Canada from the Isle of Wight disease 

 and the danger of its introduction at the meeting of the apiculture 

 section of the Association of Economic Entomologists in Toronto in 

 December, 1921, and the conference of March 9 called by the com- 

 mittee of the apiculture section, the committee recommended to the 

 Dominion Government that immediate steps be taken to prevent the 

 introduction of the disease into Canada. It was further recom- 

 mended by this committee that the action of the Dominion and 

 United States Governments be such as in no way to interfere 

 with a free interchange of bees between the two countries. The 

 Dominion apiarist was a member of the committee of the apiculture 

 section. The action of the Dominion Government consisted of an 

 order of the Deputy Minister of Agriculture dated April 22, 1922, 

 prohibiting the importation into Canada of bees, used and second- 

 hand hives, and raw hive goods and products, except honey and 

 wax, from the continent of Europe. A later statement from the 

 deputy minister includes Great Britain in this prohibition. 



At no time has any noteworthy disease or abnormality of adult 

 honeybees been reported at any place in Canada, and it is believed 

 that there is no disease within the boundaries of that country which 

 has not been found within the limits of the United States. Bees 

 sent to the Bureau of Entomology from various points in Canada 

 have shown Nosema apis, which is not considered a disease danger- 

 ous to adult honeybees under the act of Congress. Bees examined 

 by the Dominion apiarist have failed to show the presence of 

 Acarapis woodi. The former Dominion apiarist, F. W. L. Sladen, 

 was familiar with the Isle of Wight disease in England, and several 

 years before his death recommended a joint action of the Dominion 

 of Canada and the United States to prevent the introduction of this 

 disease, which he knew from experience to be dangerous. 



GREAT BRITAIN. 



It is unnecessary to attempt to give the distribution of the Isle 

 of Wight disease in Great Britain, as it may be assumed to be dis- 

 tributed throughout that country. Since the announcement of the 

 cause of the disease, a large number of writers in England have dis- 

 cussed this disease and its treatment, but so far no definitely specific 

 treatment for it has been announced. Doctor Rennie has continued 

 his observations on this disease and has issued several interesting 

 articles {51, 52, 53) on his findings. He has also published some 

 records of the distribution of the disease.
