He subsequently identified several other alternative host plants (including the weevil's likely original host) that have proved critical to the understanding of boll weevil ecology. These discoveries helped to explain the failure of subsequent large-scale, expensive and environmentally damaging eradication campaigns in the US and elsewhere.
He later identified several other potential host plants (including the weevil's likely initial habitat) that played a key role in elucidating boll weevil ecology. These discoveries helped to explain why subsequent large-scale, costly, and environmentally harmful eradication efforts were unsuccessful in various locations.
