The Common Stalk Borer, Papaipema nebris, is a pest of a very wide range of host plants.
DescriptionEdit
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 SignsEdit
Tunnelling of stalks and twigs.
EcologyEdit
Overwintering as pupae in weedy areas. More problematic in no-till systems, since plowing under provides good control.
