| Abstract: | ABSTRACT: 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. |
