SUCKING INSECTS. 



Among the many insects which trouble the pomologist there is 

 perhaps no one group which is more injurious than are the 

 scale insects, plant lice and other sap-sucking bugs. In Maine 

 there are a number of species of scales but owing to their small 

 size, and sombre coloring they are often passed unnoticed. The 

 increasing practice of spraying of orchard trees by our fruit 

 growers will tend to check the spread of species already estab- 

 lished and prevent new ones gaining a foothold. As these 

 insects have sucking mouth parts and live upon the juices of 

 the host plants, they must be fought by means of contact sprays, 

 such as tobacco, oil emulsions, whole oil soap, or lime-sulphur. 

 Belonging to these bugs which feed by means of a jointed beak 

 are the following serious orchard pests to which we have given 

 special attention :
