10. The Asian cycad scale was introduced to Florida in 1992. These insects are not hard to kill, but they reproduce rapidly. They feed on cycads and have significantly reduced the numbers of these plants. The scales infect the roots as well as the leaves of the palms. The immature insects cannot fly, but they can become airborne in high winds. To reduce their population, two natural predators were introduced in 1997 and 1998.
