Boll Weevils1 are Attracted to Volatile Oils from Cotton Plants

Abstract
The volatile oil obtained by distilling cotton plants was attractive both to emerging overwintered boll weevils, Anthonomus grandis Boheman, and to late-season migrating weevils in the field. The evidence indicates that the volatiles from cotton plants influence the migratory behavior of boll weevils and also are sufficiently attractive to guide overwintered boll weevils to fields of seedling cotton.
