The mulberry leaf roller, Diaphania pulverulentalis (Hampson), is a significant defoliator of mulberry (Morus spp.) and a major pest in sericulture across India. Until now, its occurrence in Saharanpur district, Uttar Pradesh, had not been documented. This study reports the first confirmed presence of D. pulverulentalis in the mulberry-growing areas of Saharanpur, based on field surveys, morphological identification, and laboratory rearing conducted from July 2023 to February 2024. Larval infestation was observed on Morus alba, with typical leaf-rolling behaviour and feeding damage. The pest’s life cycle, infestation pattern, are briefly discussed. The pest passed through five distinct larval stage with a total duration of 14.51±3.33 days. The duration of pupal period, adult male and female was recorded of 8.31±0.77, 4.5±0.52, and 7.5±0.52days respectively. This record expands the known geographical range of D. pulverulentalis into the north western plains of India.
