32 The Horticulturisf s Rule- Book. 



Peach. Aphis {Aphis persiccc-niger, Smith). — A small black or 

 brown plant-louse which attacks the tops and roots of peach 

 trees. When upon the roots it is a very serious enemy, 

 stunting the tree and perhaps killing it. Thrives in sandy 

 lands. 



Remedies.— Kerosene emulsion. Tobacco decoction. To- 

 bacco hoed in about the tree will destroy the root-colonies. 



Apple-tkee Borer. — See under Apple. 



Flat-headed Borer.— See under Apple. 



I^TYDiD. — This insect is often troublesome to the peach in the 

 southern states in early spring, eating the leaves and gird- 

 ling young stems. 

 Remedy. — Poisoned baits placed about the tree. 



Peach-twig Moth {Anarsialineatella^ Zeller) .—The larva of a 

 moth, a fourth inch long, boring in the ends of the shoots ; it 

 sometimes attacks the apple and strawberry -roots. 

 Remedy.— Burn the infested twigs. 



Peach-Louse or Aphis (Myzus persicce, Sulzer) . — A small in- 

 sect feeding upon the young leaves, causing them to curl 

 and die. 



Remedies. — Kerosene emulsion. Soap-and-soda wash. Soap- 

 water. Soap and arsenites. 



Plum-Curculio.— See under Plum. 



Peach-tree Borer {Mgeria exitiosa, Say). — A whitish larva, 

 about three-fourths inch long when mature, boring into the 

 the crown and upper roots of the peach, causing gum to 

 exude. 



Preventive. — Make a mound about the tree in early sum- 

 mer, a foot high, and remove it in September ; the moth then 

 lays her eggs about the top of the mound, and the tender 

 larvae are killed by exposure to the weather. A coat of 

 asbestos roofing applied about the base of the tree is recom- 

 mended as a preventive. Apply washes as for apple-tree 

 borers. Paint the crown of the tree with ordinary paint, to 

 Avhich Paris green has been added. All preventives are 

 unsatisfactory however, and the only safety is— 

 Remedy. — Dig out the borers in late fall and early spring. 



Red-legged Plea-Beetle {Haltica nifipes).—A flea-beetle 

 feeding on the leaves of peach trees, often in great num- 

 bers.
