Tomato Miner Treatment - 250 Million Nematodes (SF)

Tomato leafminers (Tuta absoluta) are insect pests that pose a threat to tomato crops across the world. They are recognizable by several characteristics. They are small butterflies with a wingspan of approximately 7 mm. Their appearance can vary, but generally they have yellow or brown wings with dark spots.

Steinernema Feltiae (SF) nematodes are microscopic worms used as a biocontrol treatment against tomato leafminers.

When applied to tomato leaves infested with leafminer larvae, the nematodes actively search for their prey. Once in contact with a leafminer larva, the nematodes enter through the insect's natural orifices. Once inside, the nematodes release specific symbiotic bacteria which multiply rapidly and cause the larva to die. The bacteria released by the nematodes produce toxins and enzymes that degrade the tissues of the leafminer larva, causing it to die. The nematodes then feed on the bacteria and decaying tissue, reproduce and seek out new prey. The action of nematodes against larvae is considered an effective and environmentally friendly method of biological control, as it specifically targets the pest without harming other beneficial organisms or humans.
