Flight enhances juvenile hormone inactivation inDanaus plexippus plexippus L. (Lepidoptera: Danaidae)

  • C. A. Lessman
  • W. S. Herman


Adult Monarch butterflies injected with3H-juvenile hormone (JH) showed a significant increase in haemolymph JH metabolites after a 40 min flight compared to unflown controls. In addition, haemolymph enzymatic JH metabolism was shown to increase with thoracic temperature increases previously shown to be associated with flight.
