Pests in Gardens and Landscapes

Raspberry cane maggot—Pegomya rubivora

Raspberry cane maggots are tiny white legless larvae. Adults are small flies.

Life cycle

Damage

Plants affected by cane maggots become wilted and discolored. Canes may also swell.

Solutions

Prune out and destroy infested shoots and canes. Keep plants properly irrigated and vigorous; lightly infested canes can recover from can maggot injury. No insecticides should be necessary.
