A good many flies have been collected during 1905, but very few of the 

 eastern records sent in are of special interest. Those given above are almost 

 all from the west, and most of them are additions to the Canadian list. All 

 the identifications have been made by leading specialists. 



INJURIOUS INSECTS OF THE FLOWER GARDEN. 



By Arthur Gibson, Division of Entomology, Central Experimental 



Farm, Ottawa. 



Growers of flowering plants in gardens are often troubled with insect 

 enemies of various kinds. Some of these attack the foliage, others the flow- 

 ers, while others again bore into the stems and even into the roots. As the 

 subject is an important one, an efPort has been made to bring together such 

 information as we had concerning certain little-known species, and to add, 

 at the same time, short notes on some of the more regularly occurring pests in 

 flower gardens, some of which may appear in destructive numbers during 

 any season. 



Injurious insects may be divided into two classes : (1) those kinds which 

 bite their food, such as caterpillars, beetles, etc., and (2) those which suck up 

 their food in a liquid form, by means of their beaks, such as the true bugs, 

 plant lice, etc. When insects, therefore, are noticed doing harm to any 

 plant, the first thing to do is to decide by the nature of the injury to what 

 class they belong. If they are biting insects, some poison, such as Paris 

 green, must be placed upon the food which will be eaten with it. If, how- 

 ever, they are sucking insects, some material which will kill by contact, such 

 as kerosene emulsion, or whale oil soap, must be used. For the convenience 

 of applying liquid applications to the foliage of plants a small spraying 

 pump will be found useful. Good hand pumps suitable for use in ordinary 

 flower gardens may be now purchased at a small cost, but it will pay in the 

 end to get a good pump, even if this should be a few dollars more. 



There are some insects, such as the borers, which cannot be reached by 

 any outside application of spraying materials. Injury to plants by these 

 insects, which work inside the stems and roots, is often of a serious nature
