Native budworm or Heliothis are a major pest of pulses and canola. Damage occurs when larvae attack seed pods prior to maturity leading to quality and yield loss. Helicoverpa punctigera are a migratory pest that fly in from the arid inland regions of Australia to southern and eastern agricultural regions on predominately northern and westerly winds.
A key pest of pulses and summer crops, armigera favour warmer environments compared to punctigera. Unlike punctigera they also tend to not to be migratory but come from local populations. They pupate in the soil over winter and emerge generally in October once temperatures start to rise. Damage is caused by the larvae that feeds on leaves, flowers and developing pods leading to quality and yield losses.
