Pest: Cassytha filiformis

Damage: Cassytha is a parasitic vine that withdraws nutrients from the noni foliage. Parasitism by this plant causes reduced photosynthesis, reduced plant vigor, and can cause plant stunting and plant death.

Distribution: Cassytha filiformis occurs on all major islands except Kaho’olawe. Severe infestations exist in the coastal areas of the Puna district and in the Kailua-Kona region on the island of Hawaii.

Hosts: Cassytha has a wide host range, including at least 15 plant species in Hawaii. Cassytha attacks plants in coastal and low-lying habitats.

  1. Manual removal of vines
  2. Avoidance
Notes: Cassytha was previously unreported as a pest of noni in Hawaii and the international literature.
