FiQ. 18. — Tomato worm. viduals so readily adapt themselves to the different hosts that their habits are apparently unchanged and in each instance similar control measures are ordinarily practiced. The potato flea beetle is perhaps the most serious pest of the newly set tomato, pepper, and eggplant. Leaves riddled with very small round holes like fine shot, accompanied with small glistening black beetles that jump when distiu-bed, identify the insect and its work. The adult beetles pass the winter in rubbish, emerging in early spring to feed on plantain or similar weeds until the cultivated plants appear above ground or are transplanted. Eggs are de- posited in the soil near the plants and from these hatch very small grubs that feed on the roots, often causing serious injuries to tubers or stunting the plant growth. Control: Bordeaux mixture.
