Apple maggot
Insect
Apple maggot
Rhagoletis pomonella (Walsh)
Diptera: Tephritidae
Distribution: Widespread and a major pest in most fruit-growing states and provinces in eastern North America, but more of a problem north of the mid-Atlantic states.
Adults are black flies with three (males) or four (females) white cross bands on the abdomen, a prominent white spot at the posterior end of the thorax, and the wings are marked with black bands in the shape of an "F" (A). The cream-colored eggs are laid singly under the skin of the fruit. The larva is a milky white, legless maggot without a distinct head but with a pointed front tip (B).
