Optimum conditions were determined for capturing.Anthonomus grandisBoheman in traps baited with males. Metal wing traps were painted daylight fluorescent yellow over a white undercoat (about 4×6-m. wings × 9-in. base) and were coated With an adhesive. Traps were baited with male boll weevils which were held in a container with a single layer of screen and placed at heights of 1–3 ft above ground around a cotton field adjacent to overwintering sites. This system, or a slight modification, would be useful in subsequent surveys and for control or possible eradication of the boll weevil with traps.
