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