destructive. Fairly effective treatment has been devised by the use of 4 oz. Car- 

 bolic Acid to the gallon of water, and this poured around the plant. 



I have to thank Dr. C. Gordon Hewitt, Dominion Entomologist, for kindly 

 allowing me to incorporate these notes, which were obtained under his authority. 



Prof. Jarvis: The Curculio and Blister Mite are two pests neglected by the 

 average grower in the Niagara district. Many are now looking after the Codling 

 Moth, but are neglecting these. I think the Blister Mite is more common than 

 Mr. Treherne reports. In nearly every orchard I have been in this year the 

 Blister Mite is very common. 



Dr. Hewitt: It is found in Quebec, too. 



3Ir. C^sar: I think Mr. Treherne is not correct in his belief that the com- 

 plete failure of an apple crop in an orchard does not lessen the number of Codling 

 Moth for the next year. I visited a fifty-acre orchard near St. Cathiarines this 

 fall, and was surprised to find scarcely any Codling Moth, especially as I had 

 pretty good reason to believe that the spraying was not very thorough. I have 

 since been informed tlmt a year ago there was almost a total failure of apples in 

 the orchard. I am expecting next year to hear of some remarkably clean orchards 

 out towards Lake Huron, where there has heen a failure of the apple crop last 

 year, and to a considerable extent this year, too. 



SOME OE THE WORK OF THE DIVISION OF ENTOMOLOGY IN 1911. 



C. Gordon Hewitt, D.Sc, DoMiNioisr Entomologist, Ottawa. 



In continuation of the practice which I started last year, it is my intention 

 to describe briefly to you some of the more important aspects of the work of 

 the Division of Entomology during the past year. I know that the members of the 

 Society are interested in the work that we are doing, and a discussion^ of the prob- 

 lems confronting us cannot but be productive of beneficial results. 



First, I should like to briefly refer to the additions to the staff of the Divi- 

 sion during the past year. Mr. John D. Tothill, and, more recently, Mr. Wm. A. 

 Ross, both graduates of the Ontario Agricultural College, have been appointed as 

 field officers. Mr. Germain Beaulieu has also been similarly appointed. With 

 ■such keen and loyal assistance on our staff of field officers as Mr. R. C. Treherne, 

 Mr. Geo. E. Sanders, Mr. John D. Tothill, and Mr. W. A. Ross, all graduates of 

 this college and special students in Entomology, I cannot allow the opportunity to 

 pass without expressing our indebtedness to Dr. Bethune, their teacher, for turn- 

 ing out men with such an excellent training, a training which enables them to 

 tackle problems the solution of which may have a most important bearing on 

 Canadian agriculture or horticiilture. I hardly like to think what we should do 

 without the Entomological Department at Guelph for our supply of men. Another 

 appointment of great importance which has been made is that of Professor J. M. 

 Swaine as Assistant Entomologist. Professor SwaineV valuable work on the 

 Scolytida' is well-known to all of you, and it is my intention that he shall have 

 charge of the forest insect work. The importance of investigations on forest in- 

 sects in relation to the conservation of our forest in Canada lends great significance 

 to his work and the possibilities of its further development. A beginning has 

 been made of a scheme of establishing field laboratories in different regions 

 according to the requirements of those regions. Through the kindness of the
