Few other weevils would be confused with sweetpotato weevil. All stages may be found almost anytime. Eggs are deposited singly in a small cavity that the female eats in stems or sweet potatoes or in cracks or crevices. A generation takes about one month to 6 weeks. Adults can fly well with reports of over a mile and they may live up to 8 months.
Mouthparts are for chewing.
Found on sweet potatoes in the field and in storage. Larvae tunnel into tubers and stems. They probably also feed on related plants like morning glory. For additional information, contact your local Texas extension service agent, or search for other state extension service offices.
