Sugarcane spittlebug

Systematic position. The species belongs to the order Hemiptera and the family Cercopidae, commonly known as spittlebugs. These insects are recognized as major pests in tropical agricultural systems, particularly affecting sugar-producing regions in the Americas.

Host crops. While sugarcane is the primary host for Aeneolamia lepidior, the pest also utilizes various pasture grasses such as Brachiaria species. This host diversity allows the population to survive and reproduce even during the off-seasons for the primary crop.

Biology and life cycle. The life cycle comprises an egg stage, five nymphal instars, and the adult stage. The nymphs are subterranean or reside at the base of the plants, producing a protective frothy substance that prevents desiccation. Adults are highly mobile and tend to congregate on the aerial parts of the host plants to feed.

Nature of damage and harm. The feeding process involves piercing plant tissues and extracting sap. During feeding, the insects inject salivary toxins into the plant, which leads to chlorosis, necrotic spotting, and eventual wilting of the leaves. Severe infestations significantly reduce the biomass and sucrose content of the harvest.

Control measures. Integrated Pest Management (IPM) is essential for controlling spittlebug populations.

• Application of biological agents like Metarhizium anisopliae to control nymphs.
• Monitoring insect density using sticky traps and field surveys.
• Strategic use of targeted insecticides during peak emergence.
• Cultural practices aimed at minimizing debris and disrupting the nymphal habitat.
