Sugarcane borer moth

Description

  • Adult: Yellow or yellow-brown moth with narrow brown lines running the length of the forewing.
  • Larvae: White and hairy with a brown head and sometimes brown spots.
  • Eggs: Flattened, oval and laid in clusters so they overlap like fish scales. Initially white, but turn orange with age. 
     

Timing of damage: Early to mid-season

Type of damage: Early in the season, larvae feed on the whorl. Later, they burrow into the stalk and sometimes the ears.

Scouting: Check 20 plants in five separate locations.

Economic threshold: There is no established threshold, but treatment is often more effective if 
applied when the larvae are young and before they have bored into stalks.
