1916] Entomology in the British Empire 23 



the importation of certain classes of nursery stock and vegetable 

 products, for example, the importation of conifers and ever- 

 greens from the New England States is prohibited on account 

 of the gipsy moth, of potatoes from California on account of 

 the potato tuber moth {Phthorimaea operculeUa) , of non- 

 canned fruit from the Hawaiian Islands on account of the 

 Mediterranean fruit fly {Ceratitis capitata). The field work 

 against the brown-tail moth in Nova Scotia and New Bruns- 

 wick is also carried out under the regulations of this Act. 

 Each winter the whole of the infested area in these two provinces 

 is scouted and all the winter webs of the brown-tail moth are 

 collected. This careful work has so far prevented the establish- 

 ment of this insect in New Brunswick and has kept it from 

 increasing beyond harmless proportions in Nova Scotia. 



It would exceed the limits which must necessarily be set to 

 an account of this nature if I permitted my enthusiasm to 

 exceed my judgment and described further aspects of our work 

 which are reported annually, although I am aware of the 

 humiliating fate that annual reports not infrequently suffer. 



Mention should be made of the valuable investigations 

 that are being carried on at Agassiz, B. C, by Dr. Seymour 

 Hadwen, Assistant Pathologist of the Health of Animals 

 Branch of the Dominion Department of Agriculture, on the life 

 histories of Hypoderma bovis and H. lineata, which are undoubt- 

 edly the most important hitherto carried out. 



In certain of the provinces applied entomology has made 

 encouraging progress, particularly during the last few years. In 

 Ontario, in which province applied entomology in Canada had 

 its birth, the Entomological Department of the Ontario Agri- 

 cultural College at Guelph has always combined with its 

 educational work the duty of assisting the farmers and fruit 

 growers of the province in solving their problems and with this 

 work and the earlier work in Canada the name of Dr. C. J. S. 

 Bethune will always be associated. In 1912, Mr. Lawson 

 Caesar, who is Associate Professor of Entomology in the 

 Agricultural College, was appointed Provincial Entomologist. 

 In addition to the investigatory work on insects affecting 

 fruit. Prof. Caesar has charge of the inspection of nurseries in 

 Ontario, which work is carried out under the provincial Fruit 

 Pest Act.
