Juvenile hormone: activity of aromatic terpenoid ethers

Several aromatic terpenoid ethers possess a high degree of morpho-genetic activity when assayed on the yellow mealworm Tenebrio molitor L. and the milkweed bug Oncopeltus fasciatus (Dallas). The most active compounds were the 3,4-methylenedioxy-phenyl ethers of 6,7-epoxygeraniol and the corresponding ethyl-branched homologs.
