Highlights of the research

  • Acorus calamus essential oil was toxic to S. oryzae, R. dominica, O. surinamensis.
  • α-Asarone enriched oil produced significant repellency on test insects in an hour.
  • Botanical was a potent feeding deterrent against S. oryzae, and R. dominica in 72 h.
  • The essential oil induced phagostimulant activity against O. surinamensis adults.
  • A. calamus oil caused severe ultrastructural impacts on insects’ cuticular surfaces.
