Neosilba pradoi

Systematic position. Neosilba pradoi belongs to the order Diptera, within the family Lonchaeidae. This species is recognized as a significant pest, often associated with commercial fruit production in regions where these flies find suitable hosts throughout the year.

Host plants. This fly is highly polyphagous, targeting a wide range of economically important fruits. Its preferred hosts include coffee, citrus species, mangoes, avocados, and papayas. The presence of these larvae in orchards often leads to serious quarantine concerns in international trade.

Biology and life cycle. The life cycle consists of the egg, three larval instars, pupa, and adult stages. Females typically oviposit under the fruit skin or into existing injuries. After completing their larval development within the fruit, the larvae exit to pupate in the soil environment. The duration of the cycle is strongly influenced by ambient temperature and humidity.

Damage and economic impact. The primary injury is caused by the larvae feeding on the fruit's pulp. This feeding behavior results in rapid decomposition and the breakdown of fruit tissues. Infested fruits often drop prematurely, leading to substantial yield losses and reducing the marketability of the remaining crop due to internal rot and quality degradation.

Protection measures. Managing Neosilba pradoi requires a multi-faceted approach:

• Strict sanitation protocols, including the collection and destruction of all fallen and infested fruits.
• Implementation of mass trapping techniques using synthetic lures to reduce the adult population density.
• Biological control measures, utilizing natural enemies and parasitic wasps that target fly larvae.
• Judicious use of chemical pesticides during periods of peak adult activity, following local integrated pest management guidelines.
