Effects of juvenile hormone and ecdysone on the timing of vitellogenin appearance in hemolymph of queen and worker pupae of Apis melliferaAngel Roberto Barchuk
, , Av. Bandeirantes 3900, , , Brazil
J Insect Sci 2:1. 2002..These data suggest that queens and workers share a common control mechanism for the timing of vitellogenin synthesis, involving an increase in juvenile hormone titers in the presence of low levels of ecdysteroids...
