European Scale (Aspidiotus ostrcwformis) . 



Specimens of this insect were received from Teiiticton and from Kelowna. I'p 

 to ttie present time it lias not occurred in injurious numbers. 



Apple-leaf Hoppeb {Empoa^ca mull). 



Tlie egg-blisters of this insect were abundant everywhere this spring in the new- 

 growth of the apple. Most commonly they were found in one-year-old wood, occa.s- 

 .sionally in two-year-old wood, and rarely in three-year-old. One or two eggs are 

 found in each egg-blister. In examining a large number of these eggs this spring 

 it was found that about 20 per cent, were parasitized by a small hymeuopteran, 

 which could readily be observed fully formed within the egg. The young hoppers 

 began to emerge in the laboratory on May 9th, and a week later were ijractically 

 all out. 



Two distinct broods of this insect occur in the Okanagan. Leaves attacked by 

 the leaf-hoppers rarely become curled in this district, as has been described else- 

 where, but such leaves ai'e mottled over with whitish or yellowish spots. On the 

 fruit the injury .shows as small, white circular marks about l^ inch diameter. 



Tarnished Plant-bug (Lygus pratensis). 



This insect was noted attacking a wide range of crops, but probably the most 

 damage was done to nursery stock. Leaves that are attacked when young become 

 wrinkled and curled. Sometimes small areas of the leaves become brown and die. 

 subsequently dropping out and producing a " shot-hole " effect. Blossom-buds 

 attacked are retarded in development, if not killed. Leaf-buds, when pierced at the 

 base, frequently die and drop off. 



Gheen Apple-aphis (Aphis pomi). 



This insect, which is the most widespread and destructive of our apple-insects, 

 was considerably less numerous than last year in most sections. In fact, the loss 

 resulting from its attacks in the Okanagan was this year very slight. 



Rosy Aphis (Aphis sorlii). 



This insect was found for the first time this season in the Okanagan. Specimens 

 were taken both at Vernon and Kelowna. It has not gained a very firm foothold 

 in either district as yet, but may be expected to cause trouble in the future. 



The Woolly Apple-aphis (Eriosoma lanigcra; americanaf). 



This insect seems to be upon the increase and to be growing in importance as 

 a fruit pest. Very few young orchards are badly infested, but a number of the older, 

 more or less neglected ones have suffered severely. The root form of this insect is 

 sometimes found in the Okanagan. 



Elm-leaf Louse (Eriosoma americana). 



The elm-leaves in the City of Vernon this summer were badly attacked by this 

 insect. In some cases it caused partial defoliation of the trees. 



The Cuebant-aphis (Myzus ribis). 



This insect was very common on the currants everywhere. 



The Black Cherry-aphis (Myzus cerasi). 



This aphis was fairly abundant in most sections. It is the most important insect 

 of the cherry. 



Mealy Plum-aphis (Mylopterus anintJiiiis). 



A common insect pest of the plum. 

 Cabbage-aphis (Aphis hrassicm). 



Common and injurious to cabbages and turnips.
