Rough sweetpotato weevil

Damage on storage roots (N. Smit).

• What they do to plants

  - larvae feed under the soil surface, and  gouge shallow channels on the enlarging storage roots. When extensively damaged, storage root flesh turns dark-greenish just under the grooves.

  - adult weevils feed on the foliage.

• Larvae cause greater damage than adults.

• Has only been reported to occur in Africa but is suspected to occur in the Philippines.

• Constraint only in some, relatively dry, agroecological zones.
