Although the boll weevil (BW), Anthonomus grandis (Coleoptera: Curculionidae) has been attributed to significant losses caused cotton yield in Americas, categorization as a quarentenary pest places where it is still not occurring increased its relevance worldwide. In areas widespread, suppression relies on many broad-spectrum insecticide applications. However, other control tactics are sought. Considering that early-flowering cultivars escape from infestation, we investigated if three different planting dates (November, December, and January) could alter plant life cycle, allowing plants infestation. Field trials were run two seasons (2014/2015 2017/2018), variables (days required reach each flowering stage, fruiting structures-undamaged damaged by BW, totals-number of weevils had emerged fallen structures ground) assessed over 29 33 weeks, respectively. Based number days initiate terminate time economic threshold (ET), undamaged, damaged, total reproductive structures, concluded December for Central Cerrado Brazil should be preferred tested dates. Cultivations at this date, anticipating period initiation termination, reduced infested delayed decision making pest, when compared
