Abstract
In the United States, the so-called sugarcane rootstalk borer weevil. Diaprepes abbreviatus (L.), is at present found only in the state of Florida, infesting citrus andother host plants in Orange, Seminole, and Broward Co. It was first discovered near Apopka (Orange Co.) in a citrus nursery in 1964 (Woodruff 1964). Since then it has been interrepted numerous times on plant material moving from Puerto Rico to Florida. By 1968, a quarantine area of 2600 ha had been established in Orange Co. This area has been extended 3X, and by 1975 encompassed 13,000 ha in Orange and Seminole Co. In addition, foliage and ornamental nurseries in Broward Co. have been found to be infested with weevils.
