INSECTS INJURIOUS TO THE APPLE. 



Of all the fruits grown in Canada, none can be compared in importance to the apple,, 

 whether we consider its almost numberless varieties, its universal distribution throughout 

 the country, its excellence in beauty and flavor, its commercial value, or its beneficial 

 effects upon the health of the community during our protracted winters ; and yet none, 

 probably, is more liable to suffer from the attacks of insects during every stage of its 

 growth and in every part of its organization — root and branch, trunk, leaves and fruit, 

 wood and bark, rind, flesh and core — in each and every part it has its peculiar insect foes. 

 To these different enemies we purpose now to direct the reader's attention, describing 

 briefly their several characteristics, that, with the aid of our illustrations, he may be able 

 to identify the special pests of his own orchard, and, knowing who his enemies are, take 

 measures for their effectual repression.
