Area of Science:

  • Natural Product Chemistry
  • Entomology
  • Chemical Ecology

Background:

  • Diospyros species are known sources of bioactive compounds.
  • Termite infestation poses significant economic and structural damage globally.
  • Understanding natural repellents and termiticides is crucial for sustainable pest management.

Purpose of the Study:

  • To isolate and identify quinones from Diospyros sylvatica roots.
  • To evaluate the repellent and toxic effects of the root extract and isolated quinones on the termite Odontotermes obesus.
  • To identify the major termiticidal components responsible for the observed activity.

Main Methods:

  • Extraction and isolation of six quinones from Diospyros sylvatica root chloroform extract.
  • Direct-choice and no-choice experiments to assess repellent and toxic effects on Odontotermes obesus workers.

  • Mortality assessment after 48 hours of exposure to extract and isolated quinones.

    • Main Results:

    • The root extract exhibited significant repellent properties against Odontotermes obesus.
    • The extract and four tested quinones (plumbagin, diospyrin, isodiospyrin, microphyllone) demonstrated toxicity, causing high mortality.
    • Plumbagin, isodiospyrin, and microphyllone were identified as the major termiticidal components; diospyrin showed no toxicity at the tested concentration.
    • All identified quinones are reported for the first time from this plant species.

    Conclusions:

    • Diospyros sylvatica roots contain potent repellent and termiticidal quinones.
    • Plumbagin, isodiospyrin, and microphyllone are promising natural compounds for termite control.
    • This study highlights the potential of D. sylvatica as a source for novel, eco-friendly termiticides.
