Comments
It probably spread from Mexico to Southern Texas around 1892. It then spread to all US cotton-growing areas, causing serious economic losses. Eradication was first attempted in the 1970s in several states (e.g. Mississippi, North Carolina, Virginia), and then gradually extended to all infested areas (US Boll Weevil Eradication Project).

EPPO Reporting Service 501/02 of 1990: successful eradication in California, North Carolina and Virginia. Eradication programme extended to Arizona, Florida, Alabama and Georgia.

EPPO Reporting Service (2001/014) : A. grandis has been eradicated in Alabama, Arizona, California, Florida, Georgia, North Carolina, South Carolina, Tennessee and Virginia.

By 2009, the pest was declared eradicated from all US cotton-producing states, except in the Lower Rio Grande Valley in Texas, where the eradication program continues.
