Abstract– Tryporiza nivella, commonly known as the sugarcane shoot borer, is a major pest that causes substantial damage to sugarcane crops by attacking the central shoot and inducing “dead heart” symptom. This field-based study conducted in Samastipur, Bihar, aimed to assess the effectiveness of an Integrated Pest Management (IPM) strategy combining pheromone traps, the egg parasitoid Trichogramma chilonis, and the entomopathogenic fungus Beauveria bassiana. The treatments were applied individually and in combination, and their effects were evaluated on larval populations, dead heart incidence, and overall cane yield. Results revealed that the integrated application of all three IPM components significantly outperformed single treatments and untreated controls, reducing pest pressure and improving crop productivity. Statistical analysis using OPSTAT software confirmed the superiority of the combined approach in minimizing pest incidence and maximizing yield. This study highlights the potential of IPM as a sustainable alternative to chemical-based pest control in sugarcane cultivation.
