WHO CAUSES IT?
Liriomyza spp., known as leafminer, is a genus of flies in the family Agromyzidae. They are small flies whose larvae mine the leaf tissue of host plants, including tomatoes. The life cycle of Liriomyza spp. It consists of four stages: egg, larva, pupa and adult. Adult females lay their eggs inside the leaf tissue of the plants. The larvae emerge from the eggs and feed on the internal tissue of the leaves, forming characteristic tunnels called mines. In the pupal stage, the larvae transform into adults inside the leaves and emerge to begin the cycle again.
