THE ENEMIES OF THE ROSE 117 



The next enemy to appear will be the frog-hopper 

 or cuckoo - spit, a little pale green or pale yellow 

 frog -like insect which will be found hidden in the 

 centre of a small patch of froth deposited either in 

 the axils of the leaves or on the leaves themselves. 

 This, again, must be hunted out and destroyed by 

 means of the thumb and finger, or removed with a 

 small brush and deposited in the salt and water 

 solution before mentioned. 



The Boring Grub. — Holes will be often noticed in 

 the tops of the stems of standard Roses ; these are 

 made by this pith - boring grub. As a preventive 

 the ends of standard Roses should be painted with 

 " knotting " at planting time, and the same pre- 

 caution should be adopted with the standard stocks. 

 If the holes have been already made, a piece of 

 copper wire thrust sharply down them will destroy 

 the grubs ; a little putty is used to close the holes 

 afterwards. The same grubs also occasionally pierce 

 the shoots of Roses, and seem especially fond of 

 those made by standard Brier stocks. In this case, 

 as soon as observed, the hollow ends of the shoots 

 should be squeezed until firm wood is met with, and 

 then cut off. In this way the boring grub will be 

 crushed and the affected part of the shoot removed. 



The Rose Aphis or Greenfly. — In some seasons these 

 tiny creatures are very numerous and troublesome, 

 and if not frequently destroyed increase very rapidly. 

 Most exhibitors keep greenfly under entirely by the 

 skilful use of the thumb and finger. This only 

 shows how easily such pests may be kept in check,
