Effects of Farnesol on the Corpora Allata and Accessory Reproductive Glands Morphometrics in Cataloipus Cymbiferus Krauss (Acrididae: Orthoptera)

  • Hildegarde S. Qorro
  • James R. Mainoya


The functional development of the accessory reproductive glands (ARGs) and that of the corpora alluta (CA) in the male grasshopper, Cataloipus cymbiferus, appear to be correlated. The growth of the ARGs and that of the CA glands increase with age to a maximum, 20 days after adult emergence. The increase in size of CA cells suggests increased secretory activity. However, the administration of farnesol, a juvenile hormone analogue, does not appear to have any direct effects on the growth of ARGs, although it completely blocked the growth and secretory activity of the CA.
