Eradication was declared in January 1994. The brown citrus aphid was found November 3 on an orange tree in Fort Lauderdale during a routine inspection of fruit fly traps by a USDA inspector. The brown citrus aphid is slightly larger than other aphid species that feed on citrus. It causes young leaves and stems to die prematurely. The aphid is capable of building up large populations quickly, with new generations produced every 6-8 days under favorable conditions.
Host plants are citrus or close relatives.
This aphid is not known to attack anything else. New flush is usually colonized. No need to search old leaves. Wingless adults are very shiny black. Only one other species has shiny black adults and it is quite rare.
