THE CANADIAN KNTOMOl.OGIST 21 



AXMAL MEETING OF THIC KN'roMOL()(;iCAL SOCIETY OF 



ONTARIO. 



Tlu' ht"l\-sixth annual niccling of the Enloniologica! S(x-iet\- ol Ontario 

 was lu'ld at Ottawa on No\'eml)<>r the sixth and seventh. The attendance 

 was good and \er\- representative of the national character of the Society, 

 members being present from Nova Scotia. New Brunswick, Quebec, Ontario, 

 Manitoba and British Columbia. In addition to the Canadian members there 

 were two welcome visitors from the United States: Mr. C. L. Marlatt, Assistant- 

 Chief of the Bureau of Entomology, Washington D. C. and Dr. Summers of 

 Massachussets. 



The programme, as the list of subjects given below will show, was not only a 

 full one but co\ered a wide range of Entomology. Most of the papers were of 

 an economic nature, but several — and these not the least interesting, 

 eschewed the economic aspect altogether and gave instead the results of the 

 observations and studies of the insect lover and naturalist. 



The papers which aroused the most discussion were "The Chief Factors 

 in Natural Control" by J. D. Tothill and " My Experience in Dusting and Spray- 

 ing" by Father Leopold. It was very interesting to observe the difference of 

 opinion as to the importance of such control factors as w^eather or climate, 

 and scarcity of food supply. There was a'so a decided difference of opinion as 

 to the best spray mixtures for apple orchards between the Nova Scotia men on 

 the one hand and the Ontario, Quebec and British Columbia men on the other 

 hand. The Nova Scotia Entomologists claimed that under certain weather 

 conditions lime- sulphur applications caused a very noticeable drop of apples 

 which lessened the size and value of their crop; the Entomologists of the other 

 provinces claimed that in their respective provinces there was no evidence of this 

 drop or of any lessening of the crop. Father Leopold's experience was in 

 accordance with the latter view. 



The symposium on the Cabbage Maggot was interesting and. not only 

 corroborated last year's evidence of the value of corrosive sublimate as a remedy 

 for this pest, but also brought out several new and possibly eciually good remedies. 

 The results of further experiments with these next year will therefore be looked 

 forward to with interest. 



The popular cAening lecture by C. L. Marlatt on "How the United States 

 is preventing the Introduction of Foreign Insect Pests and Plant Diseases" was 

 highh- appreciated and felt to be of special value to Canadian Entomologists 

 as was pointed out b\- the President of the Society when proposing a vote of 

 thanks. 



On the evening of the seventh the members and guests were entertained 

 by the Ottawa Naturalists' Club at a smoker in the rooms of the University 

 Club. 



The ofificers for next year are: — President, Mr. Arthur Gibson; Vice-Presi- 

 dent, Mr. F. J. A. Morris; Secretary Treasurer, Mr. A. \V. Baker; Curator, 

 Mr. G. J. Spencer; Librarian, Dr. C. J. S. Bethune; Pxlitor, Prof. E. M. Walker. 

 The list of papers read was as follows: — 



1. Insects of the Season in Ontario — ^W. A. Ross and L. Caesar. 



2. Insect Conditions in the Province of British Columbia — ^R. C. Treherne.
