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.
