Cunningham, who died in N'ancouver in February of this year, and he took 

 with him, in addition to the respect of all his associates, the main credit 

 from an entomological standpoint of having established a world-wide 

 reputation for the Province in the matter of its freedom from the codling- 

 moth. I think there is no question about this and it is right to give honour 

 where honour is due. Mr. Cunningham by his foresight and will-power laid 

 the foundation-stones upon which we as oflicers of the Department who 

 followed him have built. 



In 1 91 6, again several new insect pests not previously recorded for 

 the Province were reported and determined by officers of the Entomological 

 Branch. It may almost appear that the number of insect pests were 

 increasing in due proportion to the increase of the entomological staff, but, 

 of course, these insect pests doubtless had been present for several years 

 and their identity had lain dormant until discovered by entomologists whose 

 duty it was to investigate insect conditions. The pests that I have noted for 

 this year are the chrysanthemum-midge, which was reported to me by Mr. 

 R. M. Winslow and E. W. White, of the Provincial Horticultural Branch 

 from Victoria; the mangel-root or sugar-beet aphis (Pemphigus betas), 

 reported to me by W. T. McDonald, Provincial Live Stock Commissioner 

 from Victoria; and the apple-maggot (Rhagoletis pomonella), taken by 

 myself at Penticton on July 26th, 1916, and identified by Dr. J- M. Aldrich, 

 of Washington, D.C. The identity of the sugar-beet aphis was proved by 

 Mr. W. A. Ross, of the Entomological Branch, Ottawa. 



During 1916 the Bulletin No. 12 of the Dominion series appeared 

 from Ottawa detailing the habits of the cabbage-root maggot. During 1917 

 the study of the pear-thrips on the Saanich Peninsula continued, with Dr. 

 A. E. Cameron and the writer in charge. The results of this work were 

 summarized into bulletin form during the winter of 191 7 and appeared as 

 Bulletin No. 15 of the Dominion series in January, 191 8, in time for the 

 opening of the spring campaign of that year. 



Mr. W. Downes was engaged as temporary field assistant in the spring 

 of 191 7 to carry on the field data on the pear-thrips in the neighbourhood 

 of Victoria. Mr. J. D. Tothill also visited the Province this year and opened 

 up a field laboratory at Royal Oak, on Vancouver Island, to commence the 

 study of tent-caterpillars, spruce-budworm, and fall web-worm. Mr. Tothill 

 had charge of the natural-control features of Dominion Entomological 

 Branch studies, and it was under the auspices of the Federal Government 

 that he commenced work in this Province. His studies carried him far and 

 wide throughout the Province, but Lillooet, the Lower Eraser Valley, and 

 Vancouver Island claimed his attention to the greatest extent. 



The most noteworthy economic insects discovered this year were the 

 pea-weevil at Penticton and Summerland, reported to me by the Provincial 

 Eield Inspectors, and the apple-maggot at Victoria, discovered by Mr. 

 Downes. The writer also undertook this year to investigate certain stored- 

 product insects, and heat was used for the first time in the Province to 

 control such insects. Calandra oryza, Laemophleus ferrugineus, Tribe-
