The apple maggot (Rhagoletis pomonella), also known as the railroad worm (but distinct from the Phrixothrix beetle larva, also called railroad worm), is a species of fruit fly, and a pest of several types of fruits, mostly apples.
Rhagoletis juglandis Cresson, 1920 – walnut husk fly; Rhagoletis juniperina Marcovitch, 1915; Rhagoletis kurentsovi (Rohdendorf, 1961) Rhagoletis lycopersella Smyth, 1960; Rhagoletis macquartii (Loew, 1873) Rhagoletis magniterebra (Rohdendorf, 1961) Rhagoletis meigenii (Loew, 1844) Rhagoletis mendax Curran, 1932 – blueberry maggot
Rhagoletis mendax is a species of tephritid fruit fly known by the common name blueberry maggot. The blueberry maggot is closely related to the apple maggot ( R. pomonella ), a larger fruit fly in the same genus.
This is a list of species of the tephritid fruit fly genus Rhagoletis. As of 2006, 70 species have been described. As of 2006, 70 species have been described. Rhagoletis acuticornis (Steyskal)
Along with the apple maggot, it is the worm that people encounter when biting into an infected apple. [ 1 ] [ 2 ] Because the larvae are not able to feed on leaves, they are highly dependent on fruits as a food source and thus have a significant impact on crops.
Another distantly related family of flies, Tephritidae, are true fruit flies because they are frugivorous, and include apple maggot flies and many pests. The best known species of the Drosophilidae is Drosophila melanogaster , within the genus Drosophila , also called the "fruit fly."
Bush is best known for his research on the process of speciation, [2] especially for his evidence of sympatric speciation in the apple maggot fruit fly, Rhagoletis pomonella, which shifted from using its native host, hawthorn tree, to using the domesticated apple tree in the last 150-200 years. [3] [4]
The hawthorn fly (Rhagoletis pomonella), also known as the apple maggot fly, appears to be undergoing sympatric speciation. [45] Different populations of hawthorn fly feed on different fruits. A distinct population emerged in North America in the 19th century some time after apples , a non-native species, were introduced.
