The positive confirmation was made by USDA late Wednesday. So far, the pest has been discovered only in urban areas of Calexico and El Centro. There have been no discoveries of the pest in commercial agriculture areas. The pest, which can spread by wind, drains the sap from plants while injecting toxic saliva as it feeds. Infested plants show a malformation in leaves and fruit, stunted growth and a white, cotton-like mass at the end of its branches.
Severe infestations can destroy the plant.
Residents are encouraged to report any such appearances to their local agricultural commissioner's office.
