White Ants, or Termites. These insects often infest 

 orchard trees in the southern States, particularly in 

 orchards which contain old stumps or rubbish.

 trunk and branches of the tree. 



Willow. WILLOW- WORM ( Vanessa antiopa, Linn.). Larva, 

 nearly two inches long, black, feeding upon leaves of 

 willow, elm, and poplar ; two broods. 



Remedy. Arsenites. 



Wire-Worm (Various species). Slim and brown larvae, 

 feeding upon the roots of various plants. They are the 

 larvse of the click-beetle or snapping-beetle. 



Remedy. Arsenites sprinkled upon baits of fresh clover 

 or other material which is placed about the field under

 a good bait. The best treatment is to plough infested land 

 in the fall. A system of short rotations of crops will 

 lessen injury from wire-worms.
