Icerya genistae in Barbados and the United States


Name: Icerya genistae Hempel

Taxonomic Position:

Animalia : Arthropoda : Insecta : Hemiptera : Margarodidae


Florida Department of Agriculture and Consumer Services has published an informative alert about the recent Icerya genistae detections in Florida. These detections were a first for Florida and the continental United States. There are also new reports of I. genistae in Barbados, where the pest is spreading quickly and causing damage to numerous vegetable and ornamental crops. Besides Florida and Barbados, this insect has only been collected from Brazil.

Issues of Concern:

Little is known about its biology or natural enemies and there is concern this scale could be confused with other species of Icerya, such a I. purchasi, that is already present in Florida.
