Neosilba

Neosilba certa is a significant agricultural pest belonging to the Lonchaeidae family, within the order Diptera. These small flies have become a major concern for fruit growers in various regions, specifically because their larvae are highly adapted to infesting commercial fruit crops.

The host range of this pest is diverse, primarily affecting tropical and subtropical fruits such as citrus, mango, papaya, and coffee. Given the ability of the larvae to survive inside the pulp, infestation often leads to severe losses in both yield quantity and the commercial quality of the fruit.

The biological cycle of Neosilba certa is closely linked to fruit maturity stages. Adult females pierce the skin of the fruit to deposit their eggs. Once the larvae emerge, they feed internally on the fruit tissue, creating tunnels that destroy the integrity of the fruit and promote rapid decay.

Damage is often difficult to detect until the fruit begins to show signs of premature rotting or soft spots. The economic impact is profound, as infested fruits become unmarketable and are prone to secondary infections from fungi and bacteria that enter through the holes created by the larvae.

Effective management and control strategies include:

• Deploying pheromone or sticky traps to monitor adult fly populations.
• Strict sanitation protocols, including the regular removal and destruction of fallen or infested fruits.
• Strategic application of targeted insecticides during peak oviposition periods.
• Promoting natural biological control agents that predate on the larvae or adults.
