The role of tyramine and octopamine in the regulation of reproduction in queenless worker honeybees

Workers orally treated with tyramine had more developed ovaries, produced esters in the Dufour’s gland and 9HDA in the mandibular glands [1].

Mandibular glands

Left mandible (inner side) and mandibular gland (marked red) of honey bee worker. After Snodgrass (1956, fig. 23c) [7].
