Conotrachelus nenuphar, the Plum: Curculto. This insect has been more 

 than usually destructive to apples in the Eastern Townships this season. In many 

 districts it is our most destructive apple fruit insect. 



Poison sprays are only partly effective in its control, and need to be supple- 

 mented by careful destruction of the fallen fruit, particularly the small fruits 

 which drop early in the season. In controlling this insect lead arsenate should be 

 used, three to four pounds per barrel for the first two summer sprays. 



Cultivated orchards are less seriously affected than those in sod. Surface 

 cultivation in July and August, pruning and spraying all tend to keep the beetle 

 in check. Haws and wild plums, in which the Curculio breeds, and neglected 

 orchards, serve as centres for breeding and distribution of this as well as other 

 apple-fruit pests. Nearby orchards, no matter how well cared for, may be seriously 

 infested.

Anthononious qvadrigihhus, the iVppLE Curculio. We have the Apple Curculio 

 in injurious numbers in the region about Covey Hill. 



Carpocapsa pomonella, the Codling Moth. We have heard less of the Cod- 

 ling moth in Quebec orchards this season, probably because the Maggot and Cur- 

 culio attracted so much attention. Spraying, which so readily controls the Codling 

 Moth, is also being more widely practised. 



Cymatopliora rihearia, the Currant Span-worm, and Pteronus rihesii, the 

 Currant Saw-fly, were present in unusual numbers. The former is quite common 

 on Montreal Island. 



Scsia tipuUformis, the Currant Borer, is destructive locally; but controlled 

 by careful pruning. 



Oberea limaculata, the Easpberry Cane-borer, has not been so numerous this 

 season. It is readily controlled by careful pruning. 



We find an Oberea larva rather common in rose stems. It is possibly hasalis, 

 which has been collected from rose bushes. 



The worst enemy of the raspberry, in this district, is the Red Spider. In dry 

 seasons it lessens the crop very materially. Several sprayings with kerosene emul- 

 sion or fish-oil soap or frequent sprayings with water hold it in checkr^ 



There were few complaints of strawberry insects this season. Our chief insect 

 enemy of the strawberry is the White Grub; and it is seldom destructive when 

 the strawberries come at the end of a long rotation.
