White Moth Cicada

The White Moth Cicada (Lawana conspersa) is a species of planthopper belonging to the family Flatidae. Native to various tropical and subtropical regions, this insect is known to be a significant pest that affects a wide variety of cultivated and ornamental plants by sap-sucking activity.

This pest has a broad host range, often infesting fruit trees, coffee plants, tea bushes, and various ornamental species such as hibiscus. Because of its polyphagous nature, Lawana conspersa can easily spread across different plant species within an agricultural setting, posing a challenge to diverse farming operations.

The biology of the White Moth Cicada is characterized by an incomplete metamorphosis cycle. Eggs are typically laid in the plant tissue or bark, and the subsequent nymphs are covered in a white, waxy substance that acts as a protective shield against predators and environmental stress, often making them difficult to spot on the stems.

The damage caused by this insect involves the extraction of vital plant fluids, which leads to stunted growth, leaf yellowing, and deformation of shoots. Furthermore, the secretion of honeydew promotes the growth of sooty mold, which coats the leaves and significantly inhibits photosynthesis, thereby reducing overall plant vigor and quality.

Management of Lawana conspersa requires an integrated approach.

• Monitoring plantations for early signs of wax-covered nymphs.
• Manual pruning and removal of heavily infested plant parts.
• Application of systemic insecticides or horticultural oils to penetrate the waxy layer.
• Encouraging natural predators such as wasps or ladybirds where possible.
