The Cane Weevil Borer (Rhabdoscelus obscurus) continues to pose a significant threat to sugarcane farms in Fiji, with experts warning of its impact on both crop yield and quality.

The pest’s larvae burrow into the lower sections of the cane and stools, leading to reduced sugar content, deterioration in juice quality, and increased cases of rot and lodging.

In severe infestations, farmers may face substantial production losses.

Early signs of infestation can be difficult to detect, as larvae remain concealed within the cane base.

However, affected crops often display yellowing leaves, wilting, and structural weakness.

Crops that have sustained physical damage, whether from rodents or harvesting, are particularly vulnerable.

Agricultural authorities are urging farmers to adopt integrated pest management practices to limit the spread.

The use of split cane bait traps has been recommended alongside maintaining strict farm hygiene.

Removing leftover harvest material such as billets and cane tops is critical, as these can serve as breeding grounds.

Farmers are also advised to reduce stalk damage during harvesting, implement rodent control measures, and ensure only clean seedcane is planted.

Severely infested stools should be removed and destroyed to prevent further spread.
