 ing upon the stems and leaves of the tomato and husk 

 tomato. Seldom abundant enough to be very serious ; kept 

 in check by parasites.

 Turnip. Maggot. — See under Cabbage. 

 Verbena. Mite. — See page 33. 



White Ants, or Termites. — These insects often infest 

 orchard trees in the southern States, particularly in 

 orchards which contain old stumps or rubbish. 



Bemedy. — The soap-and-arsenites wash brushed over the 

 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. 

 Bemedy. — 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. 



Bemedy. — Arsenites sprinkled upon baits of fresh clover 

 or other material which is placed about the field under 

 blocks or boards. Sweetened corn-meal dough also makes 

 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.
