Administration of methyl farnesoate through the Artemia vector, and its effect on Macrobrachium rosenbergii larvae Academic Article uri icon


  • We have developed a method forthe administration ofjuvenile hormone-like compounds into crus-tacean larvae through a live food vector, the brine shrimp Artemia, commonly used in prawn aqua-culture. In crustaceans, the only juvenile hormone-like compound found to date is methyl fame-soate (MF), the unepoxidated form of insect juvenile hormone lll. Since MP is hydrophobic, its administration to crustacean larvae in aqueous culture media is problematic. Accumulation of the compound in Artemia cultured in a lipid medium enriched with MF was verified by HPLC, which demonstrated the stability of the compound within the vector. Artemia that were cultured in media containing [3H] MF accumulated 7.27% of the total radioactivity added. About 0.065% of the total radioactivity added was found in 20 M. rosenbergii larvae fed on the enriched Artemia. MF freshly administered daily to M …
