Grandlure: Use in Boll Weevil Control and Eradication Programs in the United States

The grandlure-baited boll weevil trap is an essential component of most, if not all, boll weevil control programs. While there are other minor uses of grandlure, the major use is as an attractant for the boll weevil trap. The Southeastern Boll Weevil Eradication Program uses the grandlure-baited boll weevil trap to determine areawide distribution of boll weevils, field-by-field presence of boll weevils, where and when to apply insecticide treatments and suppress very low populations of boll weevils.
