Tuta absoluta

The Tomato Leafminer, Tuta absoluta, is a relentless pest that targets tomato crops with surgical precision. Originating from South America, this small moth has spread across Africa, rapidly becoming one of the most feared threats to open-field and greenhouse tomatoes. The larvae burrow into leaves, stems, and fruit, causing unsightly trails, premature fruit drop, and significant yield loss. In South Africa’s warm climate, Tuta can cycle through multiple generations a year, allowing populations to explode if left unchecked.

Managing Tuta requires a comprehensive, preventative approach. Once established, this pest is notoriously difficult to eradicate due to its cryptic feeding habits and resistance to many synthetic insecticides. The best prevention is through monitoring and mass trapping. We have found this pest to be active year round on Livingseeds Farm (our winter minimums are -10 Deg C) A reactive approach often leads to crop devastation and increased management costs.

To stay ahead of Tuta infestations, gardeners should implement a strict trap monitoring system early in the season. Place traps at around knee height where adults are most active. At the first sign of increased moth activity, additional traps my be necessary to disrupt the pest’s lifecycle. 

• Traps/Monitoring

  • Tomato Leaf Miner (Tuta) : Trap System
    A complete trap system using a water-based design and pheromone lure. Effective for early detection and mass trapping of adult male moths. Replace lures every 4–5 weeks.

  • Water Trap : Trap Only
    A standalone water trap used with pheromone lures (sold separately). Place at soil level and maintain water level to retain trapped moths.
