The evening closed with an excellent illustrated lecture by Dr. S. Hadwen, 

 Dominion Veterinarian, "Agassiz on the Life History of the Ixodoidea." 



Some of the more important features brought out at the meeting were as 

 follows : 



The Diamond Backed Moth is rapidly becoming a serious enemy to cabbage- 

 growing in the Okanagan District. This year it was parasitized by a species of 

 Ichneumon. 



In the Kootenay District the Black Cherry Aphis was very prevalent, but in 

 reality proved a blessing in disguise in that the excessive growth which is usu- 

 ally necessary to remove by pruning had been checked without injuring the condi- 

 tion of the trees. 



Eoot maggots caused considerable loss to the market gardener in the Koote- 

 nay, as they did on the lower mainland. 



Mr. Cockle reported a remarkable outbreak of cutworms in June and early 

 July. Many species were in evidence, the most common being Mamesira canadensis. 



Mr. Cunningham contended that the Oyster Shell Bark Louse — Lepidosaphes 

 ulmi — was the worst pest the orchardist has to fight. He advocated the general 

 destruction of wild crab apple trees as a means of effectually combating this insect. 

 The fruit growers of British Columbia are particularly blessed by an absence of 

 any very serious orchard insect, the Oyster Shell Scale being by far the worst. 



The Narcissus Fly is a very serious pest to commercial bulb growing on Van- 

 couver Island. Its presence is not so much noted on the mainland. This is another 

 insect imported from Europe and it was contended that the life history in British 

 Columbia, in several vital ways, differs markedly from its habits in Holland 

 The "^recurvus'^ and ''barii conspicuus" types of narcissi are most subject to attack.

 bia on nursery stock:
