Leafminers & Tomato Pinworm: How to Identify, Treat & Control Them

Leafminer and pinworm larvae — including Tuta absoluta, one of the most serious pests of tomato worldwide — tunnel through leaves and bore into fruit, cutting photosynthesis and causing direct fruit damage. Fast generations make them a persistent greenhouse and field pest.

Common crops affected

How to identify it

  • Winding, pale serpentine mines in leaves
  • Blotch mines and boring into fruit (Tuta absoluta)
  • Premature leaf death under heavy mining
  • Fast build-up in protected culture

Recommended Vegalab solution: Larva Control

Larva Control (oxymatrine), targeting young larvae before they enter leaves or fruit; repeat on the label interval and disrupt the cycle with sanitation and monitoring.

Results you can mention: Larva Control (oxymatrine) has been field-trialled against Tuta absoluta and other Lepidoptera, compared with conventional insecticide standards.
