Studies in the Mississippi Delta suggest that conditions there might be suited to early season boll Weevil suppression tactics directed toward overwintering sites. Interdictory trapping in conjunction with field margin treatments and/or pinhead square applications of insecticides resulted in low subsequent field populations of boll weevils in 1989. Suppression of weevils before they become established in the field could be the major thrust of future boll weevil management/eradication programs in that area.
