Mulberry leaf production is constrained by sap-feeding and cell-content-feeding insect pests, whose damage may reduce both the availability and suitability of foliage for silkworm rearing. This narrative review examines aphids, thrips, whiteflies, pink hibiscus mealybug and papaya mealybug, with particular attention to Indian sericulture and evidence available through 2026. Published taxonomic investigations, pest-management studies and institutional reports were assessed for pest identity, injury patterns, management outcomes and implications for silkworm safety. Recent surveys indicate that mulberry-associated thrips in southern India form a species complex, making species-level identification important when interpreting damage and selecting interventions. Evidence on papaya mealybug demonstrates the value of parasitoid-based biological control, although outcomes depend on local conditions and the time required for natural enemies to become established. Field studies of insecticides illustrate why reductions in pest populations must be considered alongside the effects of treated leaves on silkworm development. Hyperspectral measurements offer potential for detecting pest-associated leaf stress but cannot yet substitute for confirmed insect identification. An integrated approach should combine clean planting material, regular scouting, selective sanitation, appropriate crop nutrition and conservation of natural enemies. Chemical interventions require authorised use and locally validated intervals before harvested leaves are fed to silkworms. Further research should establish crop-specific action thresholds and assess usable leaf yield, pesticide residues and cocoon traits under replicated field conditions.
