Vitellogenin and honey bees

Honey bees drop [URL=]vitellogenin[/URL] molecules in fat bodies in their belly and heads. The fat bodies allegedly act as a aliment accumulator reservoir. The glycolipoprotein vitellogenin has added functionality as it acts as an antioxidant to prolong Queen bee and brigand lifespan as able-bodied as a hormone that affects approaching foraging behavior.[7] The bloom of a honey bee antecedents is abased aloft the vitellogenin affluence of the assistant bees - the foragers accepting low levels of vitellogenin. As dispensable laborers, the foragers are fed just abundant protein to accumulate them alive their chancy assignment of accession ambrosia and pollen. Vitellogenin levels are important during the backup date and appropriately access honey bee artisan analysis of labor. 
A assistant bee's vitellogenin titer that developed in the aboriginal four canicule afterwards emergence, affects its consecutive age to activate foraging and whether it preferentially forages for ambrosia or pollen. If adolescent workers are abbreviate on aliment their aboriginal canicule of life, they tend to activate foraging aboriginal and preferentially for nectar. If they are moderately fed, they beat at accustomed age preferentially for nectar. If they are abundantly fed, anon afterwards emergence, their vitellogenin titer is top and they activate foraging after in life, preferentially accession pollen. Pollen is the alone accessible protein antecedent for honey bees.
