Sympatric Speciation in Phytophagous Parasitic Insects (original) (raw)

Abstract

The appearance of new insect pests on economically important plants is a well-known phenomenon to many applied biologists. In addition, populations of introduced or native insects are frequently encountered which exhibit different host preferences, but which are morphologically indistinguishable from one another (Brues 1924, Simms 1931, Mayr 1942, Andrewartha and Birch 1954, Zwölfer and Harris 1971). These so-called host races sometimes actually represent previously unrecognized reproductively isolated sibling species. Others appear to retain their distinct host preferences and other biological traits in the absence of any observable barriers to gene flow between the races. Two classic examples in North America are the codling moth (Laspeyresia pomonella), introduced from Europe in 1750, which shifted from apples to walnuts about 26 years after it reached California in 1873 (Essig 1931, Foster 1912), and the apple maggot (Rhagoletis pomonella) which moved from its native host hawthorn to introduced apples in 1864 and cherries less than 20 years ago (Bush 1966, 1969a,b, 1974).
