Seasonal variation of flavonoid content in bee bread: Potential impact on hypopharyngeal gland development in Apis mellifera honey bees

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.

Gland Development

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.
