Abstract
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. Summer- and early fall-maturing varieties are particularly vulnerable, but hard winter apples are sometimes infested. Thin skinned sweet and subacid varieties are most susceptible, but acid varieties may be attacked. Plum, pear, and cherries also serve as hosts, but usually the apple maggot is not a serious pest of these fruits. Crab apples are invariably infested by this pest. A closely related species, the blueberry maggot fly
(Rhagoletis mendax Curran), is important as a pest of cultivated blueberries.
