    The adult moth is an agricultural pest, attacking fruit. It has a sharp proboscis that it uses to penetrate the fruit in order to suck the juices. After the fruit has been pierced, fungi and other microorganisms can enter the fruit and cause it to rot. The moth is is known to attack many fruits, including:

  • Banana,
  • Citrus
  • Lychee,
  • Mango,
  • Pomegranate, and
  • Tomato.

    Control is being attempted using :

  • catching the moths by hand with a net,
  • UV light moth trap,
  • filling the area with smoke,
  • pheromone traps,
  • coating fruit with repellant oil,
  • protective nets,
  • poisonous baits,
  • playing bat-like sounds,
  • the larva-parasitoid wasp Euplectrus melanocephalus ( EULOPHIDAE),
  • the egg-parasitoid wasp Telenomus lucullus ( SCELIONINAE), and
  • the egg-parasitoid wasp Trichogramma chilonis ( TRICHOGRAMMATIDAE).
