SS FRUIT TREES AND THEIR ENEMIES 



Coiiimoji Vapoiirer MotJi {Orgy id antiqua). — The 

 caterpillar feeds on the leaves of many trees, besides 

 that of the pear. It is i| to 2 inches long, dark grey 

 with red spots, having four large tufts of dull yellow 

 or brown hairs on its back, and five pencils of hair at 

 the head, sides and tail. It spins its cocoon on the 

 branches and leaves, from late May till August. The 

 wingless female lays her eggs on the cocoon. 



Remedies, — Remove and destroy the cocoons when 

 found, especially those with eggs on them, or those 

 found in winter. Spray in summer, while the cater- 

 pillars are feeding, with weak emulsion or arsenate. 



Plums 



TJie Plum Leaf'Cnriing Aphis {Aphis pnini). — The 

 leaf-curling plum aphis appears long before there are 

 any signs of the buds swelling, and may be found 

 early in March, near a bud, as a large, fat, dull, plum- 

 coloured aphis. This mother-queen produces green 

 living young, which are ready to attack the young 

 unfolding leaves after the blossom has fallen. By 

 piercing the leaves, they make these curl up, and thus 

 effectually protect themselves from being reached 

 directly by any spray-fluid. They have very short 

 honey tubes, and can at once be distinguished by 

 this from an allied aphis {A, priinifolice), which has 

 long honey tubes. This latter aphis is green, and 

 hatches later in the season. 



Remedies. — A. pnuii, as well as A. pnmifolice, may 

 easily be destroyed by spraying with weak emulsion, 

 or caustic emulsion, before the buds burst. Lime and
