Mediterranean fruit fly \Med`i*ter*ra"ne*an fruit" fly\, n.
A small two-winged fly ({Ceratitis capitata}), a native of
the Mediterranean countries but now widely distributed in
warm regions, which can cause great damage to citrus and
other succulent fruit crops when present in large numbers. It
is black and white and irregularly banded. It lays eggs in
ripening oranges, peaches, and other fruits; when the eggs
hatch into larvae (maggots) inside the fruit, they cause the
fruit to decay and fall, and make the fruit unsaleable. It is
also popularly called the {medfly}.

Note: The possibility of infestation by this and other crop
pests has caused some states such as California, where
fruit is a major export, to ban the importation of
fruit from other regions. Outbreaks of infestation with
the medfly have caused California to mobilize major
eradication campaigns and have been the subject of
political faultfinding. The eradication tactic, of
releasing sterile males to break the reproductive
cycle, has been used to deal with outbreaks of the
medfly.
