• Release of Isotima javensis parasites is found successful against top borer.
• Inundative releases of the egg parasitoid Trichogramma chilonis or Trichogramma japonicum@ 50,000/ha at 10 days interval after appearance of borers.
• Release of the lepidopteran ectoparasitoid Epiricania melanoleuca@ 4000 - 5000 cocoons or @ 4 - 6 lakh eggs/ha to checks its multiplication of pyrilla.
Adopt following procedure to enhanced natural enemies

• Over-wintering sites, or alternative food sources to improve survival of beneficial species.
• Avoidance of cultural practices which are harmful to natural enemies.
• Use such cultural practice which favors survival and multiplication of natural enemies.
• Provision of food like pollen and nectar for adult stages of natural enemies.
