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 subsequently found additional alternative host plants for the boll weevil (including its original host plant), which were vital for understanding the insect's ecology. These findings assisted in explaining why large-scale, expensive, and ecologically damaging eradication programs failed both in the US and elsewhere.
