The Common Stalk Borer, Papaipema nebris, is a pest of a very wide range of host plants.
Description[edit | edit source]
Caterpillars are brown with a white dorsal stripe, primarily living inside the stalks or twigs of host plants, but migrating between hosts as they grow. Adults are gray moths.
Symptoms and Signs[edit | edit source]
Tunnelling of stalks and twigs.
Ecology[edit | edit source]
Overwintering as pupae in weedy areas. More problematic in no-till systems, since plowing under provides good control.
Host plants[edit | edit source]
- Centaurea (Bachelor’s Buttons)
- Fragaria (Strawberry)
- Iris (Iris)
- Rheum (Rhubarb)
- Salvia (Sage)
Control[edit | edit source]
- Cultural controls: Control weedy hosts, plowing or tilling.
