DESCRIPTION
WHO CAUSES IT?
Helicoverpa armigera is a species of nocturnal moth belonging to the family Noctuidae. It is a pathogen that affects tomato and a variety of host crops. The life cycle of Helicoverpa armigera comprises four main stages: egg, larva, pupa and adult. Adult moths lay their eggs on host plants, and emerging larvae feed voraciously on foliage and fruit. After undergoing several molts, the larva pupates in the soil and emerges as an adult after a period of pupation. This cycle can repeat several times during a growing season, depending on environmental conditions and food availability.
SYMPTOMS
The disease caused by Helicoverpa armigera on tomato is commonly known as Heliothis. General symptoms include damage to leaves, stems and fruits, as well as the presence of droppings and larvae on the plant. The main symptoms are:
- Holes in leaves and stems.
- Damage to fruits, including perforations and rot.
- Presence of larval excrement on the plant.

- Implement crop rotation to reduce the accumulation of Helicoverpa armigera populations.
- Use pheromone traps to monitor and reduce adult populations.
- Apply biological or chemical insecticides selectively and following the recommendations for use.
- Carry out manual removal of larvae and eggs in case of mild infestations.
- Employ cultural practices that promote plant health and reduce stress, such as adequate irrigation and balanced fertilization.
