Pomegranate Fruit Borer Larva

The pomegranate fruit borer or pomegranate butterfly are pests common in Asia, especially India and Sri Lanka.  Adult males have glossy blue wings, females have brownish violet with an orange circular spot on the forewing.


PFB larvae bore into the pomegranate fruits soon after hatching from eggs laid on flowers or young fruit.  Once inside the fruit, the flat larvae (approx 2cm length) feed on the flesh and seeds.  Infested fruit will often have PFB feces near the bore holes of entry.  The holes ultimately expose the rest of the fruit to disease, and typically rot off the tree.   

Monitoring and Biological/Cultural Control:

Collect and destroy all infested fruits.  Bag immature fruits with wire screen or paper bags.

Suggested Pesticides:

  • Malathion 8EC at 1.7 to 3.4 L/ha (23-46 oz/acre).  Mix with labeled amounts of water.  Spray during flowering and repeat in 15 day intervals.
  • Deltamethrin (Decis 2.8 EC*) at labeled rates.
  • Spray Neem oil (3%) during flowering.   
  • Carbaryl at labeled rates.  Carbaryl is very hazardous to the environment: beneficial insects including honey bees, aquatic creatures, and earth worms.  Never dispose of Carbaryl in bodies of water.  Carbaryl is mildly toxic to humans.
