Green cane harvest effect on Pseudaletia unipuncta (Haworth) (Lepidoptera: Noctuidae) larvae abundance and losses caused by this pest in Tucumán, Argentina* [Full subscriber]

The larvae are nocturnal and, during the day, remain hidden under the crop residues or in the soil. Damage begins to be noticed in spring when the temperature rises. They produce damage by feeding and killing the shoots, after which new shoots are produced, but this delays the growth of the cane field.
