B. C. ENTOMOLOGICAL PROCEEDINGS, 1912. 17 



REPORT FROM THE KOOTENAY. 



Mr. Chairman and Members of the British Columbia Entomological 

 Society : — The honor has fallen to my lot to report on the insects of the 

 Kootenay districts in the place of my friend, Mr. J. W. Cockle, of 

 Kaslo. I am very sorry Mr. Cockle found it impossible to attend the 

 meeting as I am sure he would have had a much more interesting report 

 to present to you than any which I could give. My work, however, 

 as District Horticulturist brings me in very direct contact with the 

 injurious insects or those found in the orchards. With the compara- 

 tively short time I have had to prepare anything, my report must of 

 necessity deal particularly with those economic insects which have come 

 under my notice during the past year. I might state in the beginning 

 that our list of injurious insects is very small indeed, so that my task 

 will be comparatively small also. We cannot, however, expect to be able 

 to report this state of affairs for all time for, wherever we have a 

 district adapted to the culture of fruits we are always liable to have 

 it visited sooner or later by most of the serious insect pests with which 

 fruitgrowers in other districts and other countries are troubled. Fortu- 

 nately we have at the head of our Provincial Inspection branch at 

 Vancouver our old and esteemed friend, Mr. Cunningham, who is 

 always upon the look out for insects entering the Province through the 

 agency of imported nursery stock, fresh fruits, etc. This with your 

 energetic Secretary, Mr. Treherne, for the Dominion, and Mr. W. H. 

 Brittain of the Provincial Staff, along with your President, the Dominion 

 Inspector of Orchards for the Province, and all these gentlemen aug- 

 mented to a certain extent by the local horticulturists stationed through- 

 out the Province, should in a very thorough way protect our orchards 

 against the ravages of our present pests and the entrance of any new ones. 



Possibly our worst insect pest is the Common Green Aphis (A mali). 

 They came in numbers very early in the spring, but did not spread or 

 multiply so rapidly as in previous years, consequently for this reason 

 were less troublesome than in former years. We have the Apple, Plum 

 and Cherry Aphis. The Woolly Aphis (Eriosoma (Schizoncura) 

 lanigcra) fortunately has not made its appearance in the Kootenays to 

 my knowledge. 



In our spraying experiment for the Green Aphis we came to the 

 conclusion that the lime and sulphur mixture had very little effect in 

 destroying the eggs on the branches. Last year the Aphis were hatching 

 out and spreading over the branches, which were yellow with the lime 

 and sulphur. Applications of Black Leaf 1-70 gave excellent results where 

 thoroughly applied. The newer mixture. Black Leaf 40, gave very 

 varying and more or less unsatisfactory results with us. I believe this is a
