such during; the present year. The Kerosene Emulsion has proved the 

 best remedy for this pest. 



During the coming year it is my intention to use the Distillate sprays 

 more extensivel}-. They are comparatively cheap and easily applied, and 

 seem to give excellent results, both in California and Australia. Con- 

 sidering their cheapness, and the ease with which they can be applied, I 

 quite expect that they will become very popular in dealing with scale 

 insects. 



I have made provision for supplies of this ver\ popular spra\ for the 

 coming season. The order has already been sent forward. 



In conclusion, I may sa\ it is my intention to keep the public well 

 informed as to the general merits of the various spraying materials, which 

 are being constantly introduced.

Inspector of Fruit Pests. 



]Mr. Treherne — In connection with the Oyster Shell Scale, may I 

 inquire if the scale is to any extent controlled naturally by parasites in 

 B. C. ? In the southern portion of Ontario where the majority of the 

 nurseries are situated, the scale is usually commonly parasitised h\ 

 .J phi/ in us inytildspidis. 



Mr. Cunningham — \ es, large numbers are parasitised. 



Mr. Wilson — If the scale was introduced into B. C. on nursery stock, 

 as you suppose, how do you account for it being taken miles away from 

 orchard land? I have found it on June berry, Barberry, Vine Maple, 

 as well as on the crab-apple, and also at an altitude between 2-3000 feet. 



Mr. Cunningham — The medium of spread is undoubtedly birds, and 

 I have found ^oimg scales on the legs of flies. 



Mr. Treherne — If the Oyster Scale is so common in the forests, 

 would the destruction of crab-apple trees in the vicinity of orchards 

 effectually control this insect? 



Mr. Cunningham — I claim that in addition to the crab-apple trees 

 you mention, all crab-apple trees on the lands of speculators and land 

 companies should, by Government enactment, be destroyed. I ask this 

 Society to assist me in my endeavors to obtain Government control in 

 connection with these trees which undoubtedly represent a serious 

 nuisance to the Province. The acreage of crab-apple trees is so tremen- 

 dous and the ground they occupy so valuable that it would be a wise 

 measure to destroy them, as they harbor injurious insects and in par- 

 ticular this 0\ster Shell Scale.
