Abstract: Larger and wider floral bracts provide good shelter to bollworms to safely feed-upon cotton bolls whereas smaller, narrower and twisted bracts provide less protection to bollworms. Variation in normal bract size and their relationship with bollworm damage was studied in several upland cotton varieties. Our results suggest that generally varieties with larger bracts sustained more damage as compared to varieties with smaller bracts. However, in some cases where varieties with even smaller bracts received more damage due to close fruit bearing behaviour of particular varieties that probably favoured bollworms to easily reach the bolls to feed-upon
