Pollen from glanded and glandless upland cotton (Gossypium hirsutum L.) and a glanded Pima cotton (G. barbadense L.) was chemically analyzed for gossypol and 6-methoxygossypol content. The pollen contained little (<0.003% of dry weight) or none of either chemical. Behavior of honey bees (Apis mellifera L.) visiting flowers of glanded and glandless upland and Pima cotton was similar; no preference for flowers of either type of cotton was observed. Therefore, it appears that gossypol acts as neither a toxicant nor repellent to honey bees, yet none of the observed bees collected corbicular loads of cotton pollen. Rather, they fastidiously groomed pollen off their bodies before returning to the hive. Some factor(s) other than gossypol must be responsible for this behavior.
