102 THE CANADIAN ENTOMOLOGIST 



the junction of the Columbia and Okanagan Rivers, but thus far 

 has not arrived in the southern Okanagan orchards. The CodUng 

 Moth {Cydia pomonella) has gained access to the orchards of the 

 Province on four or five definite occasions, each one traceable to 

 Californian, Oregon and Ontario importations. Fortunately each 

 of these outbreaks has been caught in its incipiency, consequently 

 there is every reason to believe that few moths will appear in the 

 spring of 1915. The record of the control of this insect alone 

 constitutes an excellent example of applied economic entomology, 

 and an account of the methods used might well find its way into 

 the pages of this journal'at some later date. This insect, however, 

 is gradually moving up in natural stages towards the boundary 

 line from the South, the nearest record being at a point midway 

 between the junction of the two rivers before mentioned and the 

 Okanagan boundary line. The Woolly Aphis {Eriosoma lanigera) 

 is one of the most injurious insects in the Province, especialh' on 

 the immediate Pacific Coast region, but there is good reason to 

 believe its numbers were quite negligible about the year 1893. 

 And this is much the case with most of the farm and orchard 

 insects of the Province. 



Horticulture is at present the "first arm" of the agricultural 

 interests of the Province, and it is interesting to note that the 

 Provincial Horticulturist, Mr. R. M. Winslow, has stated that the 

 "census of 1890 showed 6,000 acres of fruit, the census of 1900 an 

 increase to only 8,000. At the time of the 1910 census the acreage 

 had increased to 33,606, and the survey of 1913 showed this further 

 increased to 38,196 acres." 



These facts, therefore, clearly indicate an original condition 

 and establishes the point that the chief interest of economic 

 entomology in British Columbia lies in one's ability to observe 

 the growth of the agricultural industry in connection with the 

 development of attendant insect pests. 



While forest and range insects are not being referred to in 

 this article, for the reason that they represent an entirely different 

 problem, it is interesting to note that not the least important of 

 the insect troubles of the orchard and farm are derived primarily 

 from the virgin lands, which, as the above rapid growth of cleared 

 land would indicate, are gradually being broken up to give place
