The area comprised within this zone, as defined by Dr. Merriam in 1900, is indicated in Chart Chart 1. The Alleghanian Life Zone (shaded area). The known distribu- tion of the apple maggot agrees approximately with this zone. For exceptions, and for details of distribution, see text. The maggot reaches its greatest abundance and destructive- ness in Maine, New Hampshire, parts of Vermont, in Massachu- setts, parts of Connecticut and New York, with an additional wide, though scattering distribution in Ontario, Michigan and Pennsylvania.
