Abstract The hypopharyngeal gland (HPG) is the principal organ of protein synthesis in honey bees. It is involved in larval rearing. We examined the fresh head weight, HPG acini diameter, and HPG protein content in worker bees engaged in different tasks and under brood and broodless conditions. Scanning electron microscopy revealed that the HPG acini diameter of worker bees was related to their task. The highest HPG volume was found in nurse bees, and the volume regressed when the task changed from guarding to foraging. The fresh head weight was positively correlated with HPG acini diameter. Although, there was no positive correlation between HPG acini diameter and protein concentration, the glandular protein concentration increased progressively in nurse bees and declined in guard and forager bees. Histochemistry revealed similar results. Despite displaying significantly larger glands, guard bee protein secretion was similar to that of the foragers. Brooding had a significant effect on HPG activity. Only worker bees from the colony with an intact brood showed elevated rates of protein synthesis; thus, it is possible that a signal was emitted by the brood, which stimulated protein synthesis in the HPG. However, the size of the HPG was similar in both brood and broodless conditions.

Various levels of wax deprivation in honey bee (Apis mellifera) colonies induced shifts in the temporal pattern of division of labour in worker honey bees. The most extreme wax stress induced an earlier onset of foraging, and an increase in comb building and the production of wax scales. Moderate wax stress induced only an increase in comb building and production of wax scales. No significant differences in development of hypopharyngeal gland acinal diameter were found, suggesting that production of wax and brood food and associated behaviour patterns develop and decline independently. The graded changes in behavioural response to various levels of stress found in this study support the concept of a reserve labour force in honey bee colonies, which can respond to stress through shifts in caste ontogeny.

Royal jelly has many important biological functions, however the molecular mechanism of royal jelly secretion in hypopharyngeal gland (HG) is still not well understood. In our previously study, six genes (SV2C, eIF-4E, PDK1, IMP, cell growth-regulating nucleolar protein and TGF-βR1) have been shown to might be associated with royal jelly secretion. In this study, the relative expression levels of these genes were examined in the hypopharyngeal gland of workers at different developmental stages (nurse, forager and reversed nurse stages). The results indicated that the relative expression levels of SV2C, eIF-4E, IMP, cell growth-regulating nucleolar protein and TGF-βR1 were reversed at reversed nurse stage compared to forager stage. We concluded that these genes are possibly candidates related to hypopharyngeal gland development or royal jelly secretion.
