40 PROTECTION OF PLANTS — 1923-24 



Macdonald College 



In 1914, the entomological staff at Macdonald College consisted of Prof. 

 W. Lochhead, Mr. E. M. DuPorte, and Mr. P. I. Bryce. Mr. DuPorte 

 devoted a large portion of his time for six years to research, but gave a few 

 lectures on special topics to advanced students. In 1920, on the departure of 

 Mr. Bryce, he was appointed Lecturer, and his time has been largely devoted 

 to advanced classes. During this period, he published a number of important 

 papers, such as, "The Nervous Sj'stem of Sphida obliqua"; ''Death-feigning 

 Reactions on Tychius picuostris" ; "The Life-history and Control of the Bud 

 Moth"; "The Structure and Functions of the Proventriculus of Gryllus"; 

 "The Propleural and Pronotal Sulci in the Orthoptera"; "Studies of Cocco- 

 haciUus acridiorium and other Intestinal Organisms of Locusts"; "The IMuscular 

 Sj^stem of Gryllus assimilis" ; "Studies of Spirochaeta duttoni", and various 

 shorter papers on economic subjects. 



In 1919, Prof. Lochhead published his "Class Book of Economic Ento- 

 mology" (Blakistons) which is used in a number of educational institutions. 

 He has also contributed many papers on entomological subjects to the Annual 

 Reports of t^ie Entomological Society of Ontario, the Quebec Society for the 

 Protection of Plants, and the Pomological Societ}' of Quebec; and to "The Jour- 

 nal of Agriculture", and other publications. A number of circulars have 

 also been prepared for the use of Quebec orchardists and gardeners. 



Among the economic insects the hfe-histories of which have been studied 

 are: — the Bud Moth, the Onion Maggot, flea beetles, and the control of grass- 

 hoppers. 



At the present time, the entomological staff consists of Prof. Lochhead, 

 Dr. E. ]\I. DuPorte, and I\Ir. A. D. Baker. An important feature of the 

 instruction is the attention given to post-graduate students working for the 

 Master's degree. The large amount of time and energy required for class- 

 room work on the part of the staff has necessarily limited the length of time 

 that could be devoted to economic studies. 



Agricultural College, Oka. 



At this institution, the position of Professor of Entomology was established 

 in 1915, and Prof. F. Letourneau received the appointment. Courses in ento- 

 mology were developed and, in addition, instruction in field work was given. 

 In all of this work, Father Leopold has undoubtedly been the guiding hand, 

 the investigations of the latter, particularly with regard to spraying problems, 

 having been most valuable. 



Montreal Entomological Society (Montreal Branch of the Entomological, 



Society of Ontario) 



In 1923, this society celebrated its fiftieth annual meeting. During the 

 years under review regular meetings have been held at which papers were 

 presented and specimens exhibited. The society has, indeed, an enviable 

 record. In its continued progress, Messrs. A. F. Winn and G. A. Moore 

 have taken a leading part.
