Abstract
The bouquet bioassay experiments under laboratory conditions revealed that the corrected percentage mortality of Helicoverpa armigera was 75.9–82.0 % at recommended dose of spinosad. Good biological efficacy of this molecule was also reflected in the suppression of larval population and reduction of damage to bolls, squares, locules and seed cotton in the field.
