		The Apple Maggot (Rhagoletis pomonella), also known as railroad worm, is a pest of several fruit (The ripened reproductive body of a seed plant) s, mainly apple (Fruit with red or yellow or green skin and sweet to tart crisp whitish flesh) s.
		The larva, which is the stage of this insect's life cycle that causes the actual damage to the fruit, is similar to a typical fly larva or maggot.
		Other "worms" inside apples can be confused with the apple maggot, however caterpillars (A wormlike and often brightly colored and hairy or spiny larva of a butterfly or moth) often feed in the apple’s core while apple maggots feed on the fruit flesh.

		The apple maggot, or railroad worm as it is sometimes called, may be found in all major apple-growing sections of eastern and midwestern States.

		The apple maggot, Rhagoletis pomonella (Walsh) (also known as the "railroad worm") is an insect native to North America Originally it fed in the fruit of wild hawthorn (Crataegus spp.), but during the past 130 years it has become a primary pest of cultivated apples, especially in the northeastern United States and southeastern Canada.
		Adults of the apple maggot are slightly smaller than a house fly, fl in color, with white bands on the abdomen (four on the female and three on the male), and the wings are conspicuously marked with four oblique fl bands.
		Apple maggots in fruits may be killed by placing the fruit in cold storage at 32º F for a period of 40 days.

		However, during three years' research in Washington no parasitism of apple maggot in apple was found, probably because the larvae burrow too deep in the fruit for the parasites to reach with their small ovipositors.
		Apple maggot activity peaks earliest on apple varieties maturing in midsummer, followed by native hawthorn and apple varieties maturing in early fall and finally by imported hawthorn and apple varieties maturing in late fall.
		Apple maggot trapping in the Northwest is complicated by the presence of the snowberry maggot, a fly that does not attack apple or other fruits but looks like the apple maggot.
