Journal of Hymenoptera Research 68: 85–101. https://doi.org/10.3897/jhr.68.29678 Abstract Honey production gains are needed to deal with high demand in Saudi Arabia. The honey bee races are facing stressful hot-arid weather conditions that can affect different aspects of physiology and behav- ior. The hypopharyngeal glands (HPGs) of honey bees have prominent roles in various social behav- iors through their secretions.
