| | Apple Maggot |
 | | Apple maggot may be able to adapt to other host plants in the future. | | | Since apple maggot renders apples virtually inedible and no completely effective cultural or biological control techniques exist as yet, chemical control becomes essential if this pest has been detected in your fruit. | | | Apples affected by apple maggots are completely unuseable and unsaleable. |

| | UC IPM: UC Management Guidelines for Apple Maggot on Pear |
| | Because the apple maggot feeds within fruit, biological control agents have not been very effective. | | | Pear growers in counties with apple maggot infestations may need to treat their crop in order to market it in noninfested areas. | | | The apple maggot is closely related to the walnut husk fly and cherry fruit fly. |

| | Several years ago, most of my apples were infested with apple maggot, and many of my friends had a like experience. | | | In fact, our own Scarab Tilbury has an impressive set of data about traps she's been using for the last five years against apple maggot, which may be added to this article in the future. | | | The young of the apple maggot are not nearly as well-behaved as the young of the codling moth. |

| | Apple Maggot |
| | Introduction: The apple maggot (AM), also known as the "railroad-worm", is a potentially serious pest, but has not been a noticeable problem in commercial orchards in the mid-Atlantic region in recent memory. | | | Red traps are more sensitive under conditions on low apple maggot fly density. | | | Injury: Pitting and dimpling on the apple surface caused by the oviposition punctures (Plate 10), and brown, winding trails caused by the excrement of the maggot and an associated bacteria under the apple's skin (Plate 11), are characteristic of AM injury. |

| | Introduction: Blueberry maggot was formerly considered a race of apple maggot, R. | | | Blueberry maggot was found to be common in the southeastern U.S. by Payne and Berlocher (1995), where an important host is deerberry, Vaccinium stamineum L. In addition to highbush blueberry, Vaccinium corymbosum L., and lowbush blueberry, the insect will infest huckleberry, Gaylussacia baccata. | | | There is a fruit fly that develops in black walnut that closely resembles blueberry maggot and may appear in traps since black walnut commonly occurs in the mid-Atlantic region. |

| | 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. | | | 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. |

| | The apple maggot is a relative of the Mediterranean fruit fly. | | | The snowberry maggot has a wing pattern exactly like the apple maggot; therefore, microscopic examination is necessary to distinguish between the two. | | | After feeding on the inside of the apple for a month or so, the maggot crawls out, drops to the ground, and burrows into the soil about 2", where it spends the winter in the pupal form. |

| | Apples are the main host of the apple maggot, but they are frequently found in hawthorn and crab apple as well. | | | The apple maggot is closely related to the walnut husk fly, cherry fruit fly, and other picture-wing flies, including the snowberry maggot, an extremely close "look-alike.' Because of their close resemblance to these insects, entomologists must dissect them to confirm their identity. | | | Apple maggot may be able to adapt to other host plants in the future. |
