Mango leafhopper

Idioscopus nigroclypeatus is a significant agricultural pest belonging to the order Hemiptera and the family Cicadellidae. Known commonly as the mango leafhopper, it poses a major threat to commercial mango production across various tropical and subtropical regions of the world.

The primary host plant for this insect is the mango tree (Mangifera indica). The leafhoppers feed on the sap of young shoots, emerging leaves, and inflorescences. This feeding behavior drains the essential nutrients from the plant, leading to stunted growth and reduced fruit set.

The life cycle consists of the egg, nymph, and adult stages. Females typically deposit their eggs into the tender tissues of the flower panicles. Their population tends to spike significantly during the flowering season, as the abundance of succulent plant parts provides ideal conditions for rapid reproduction.

Damage caused by Idioscopus nigroclypeatus is twofold: direct sap extraction and the promotion of sooty mold growth. The insects excrete honeydew, which serves as a medium for the fungus to develop on leaves and panicles, effectively blocking photosynthesis and reducing the overall tree health.

Effective management strategies include a combination of cultural practices and chemical control. Key tactics involve:

• Regular pruning to improve canopy airflow and light penetration.
• Monitoring pest populations using yellow sticky traps.
• Application of systemic insecticides during the pre-flowering stage.
• Encouraging the presence of natural predators and parasitoids in the orchard.
