The Leaf Roller (primarily caused by the larvae of the moth *Apogonia* species or similar lepidopterans) is recognized as a significant pest of mulberry in the South Indian states, particularly in Karnataka and Tamil Nadu, where sericulture is highly concentrated. While mulberry pests can occur globally, the specific classification of 'Leaf Roller' as a 'major pest' is most prominently documented in the agricultural and sericultural literature of South India. In West Bengal, the more dominant pests are often the Mealybug or Thrips, and in the North/Himalayan regions, different climatic stressors and pests prevail.
