Nacoleia octasema, the banana scab moth, is a moth in the family Crambidae. It was described by Edward Meyrick in 1886. It is found on Vanuatu[1] and in Indonesia, New Guinea, the Solomon Islands, New Caledonia, Fiji, Tonga, Samoa and Australia, where it has been recorded from Queensland.[2]

Nacoleia octasema. Commonly referred to as the banana scab moth, it is a significant pest in banana cultivation across Southeast Asia and the Pacific Islands. 

 

Distribution

Nacoleia octasema is found in various regions, including:

 

Australia: Queensland and Christmas Island

 

Pacific Islands: New Guinea, Solomon Islands, New Caledonia, Fiji, Tonga, Samoa, Vanuatu

 

Southeast Asia: Indonesia

Host Plants

The larvae of Nacoleia octasema primarily infest:

 

Banana (Musa spp.)

 

Plantain (Musa spp.)

 

Heliconia spp.

 

Pandanus spp.

They feed on the skin of young fruits, causing scarring and deformities. In severe cases, infestations can lead to significant crop loss.

Life Cycle & Damage

 

Eggs: Laid on the inflorescence or young fruit.

 

Larvae: Feed on the fruit's skin, causing scab-like lesions.

 

Pupation: Occurs within the damaged fruit or nearby plant material.

 

Adults: Nocturnal moths with a wingspan of approximately 15–20 mm.

Damage is typically confined to the outer curve of the banana fingers, but in more severe infestations, it can affect the entire bunch.

Management Strategies

 

Cultural Control: Regularly inspect crops, especially during the flowering phase. Remove and destroy infested plant material.

 

Biological Control: Introduce natural predators such as parasitic wasps.

 

Chemical Control: Use insecticides judiciously, targeting larvae before they enter the fruit.

 

Physical Barriers: Covering bunches with protective materials can reduce moth access.

Implementing integrated pest management (IPM) practices is recommended to minimize the impact of this pest.
