In vitro methyl farnesoate secretion by mandibular organs isolated from different molt and reproductive stages of the crab Oziotelphusa senex senex

Considerable evidences indicate that mandibular organ (MO) of crustaceans secrete terpenoid hormone (methyl farnesoate [MF]), which regulates molting and reproduction. In the freshwater south Indian rice field crab Oziotelphusa senex senex, MO isolated during premolt and vitellogenesis, secreted gre...

Description
Summary:Considerable evidences indicate that mandibular organ (MO) of crustaceans secrete terpenoid hormone (methyl farnesoate [MF]), which regulates molting and reproduction. In the freshwater south Indian rice field crab Oziotelphusa senex senex, MO isolated during premolt and vitellogenesis, secreted greater amounts of MF, which indicates that the regulation of the crustacean molt and reproduction is complex and also involves MF, besides steroid (ecdysteroid) and peptide (sinus gland peptide) hormones.
