Dilobopterus leafhopper

The Dilobopterus genus belongs to the order Hemiptera and the family Cicadellidae. These leafhoppers are known as significant agricultural pests, particularly in tropical and subtropical zones, where they cause severe damage to perennial horticultural crops.

The primary hosts of this pest include citrus trees and coffee plants. By feeding on the plant's phloem, these insects deprive the host of essential nutrients, leading to reduced vigour, decreased fruit quality, and stunted development of the affected branches.

The biology of Dilobopterus involves a lifecycle consisting of eggs, nymphs, and adults. Nymphs and adults are typically found on the underside of leaves. They are highly mobile and reproduce rapidly during favorable temperature conditions, making them difficult to eradicate once a population is established.

Apart from direct mechanical damage, these insects are notorious vectors for various plant pathogens. They facilitate the transmission of bacteria that cause systemic infections, such as citrus variegated chlorosis, which can lead to the death of entire orchards if not managed properly.

• Use yellow sticky traps for monitoring population density in fields.
• Apply systemic insecticides to control nymphal and adult stages effectively.
• Prune and destroy heavily infested plant material to reduce local pest pressure.
• Promote biological control through natural predators like ladybirds and spiders.
