Adult weevils overwinter in well-drained areas in or near cotton fields, and farms after diapause. They emerge and enter cotton fields from early spring through midsummer, with peak emergence in late spring, and feed on immature cotton bolls.

Where are boll weevils found?

What attracts boll weevil?

Cotton boll weevils, a species of beetle that harms cotton plants, gather in large numbers to mate. The weevils release their aggregation pheromone to attract additional boll weevils to the aggregation site.
