Preventive Control

Natural enemies


  1. Braconid
  2. Tachinid flies
  3. Trichogramma


  1. Bigeyed bugs
  2. Damselflies
  3. Hoverflies
  4. Lacewing Lacewing
  5. Ladybird beetles
  6. Minute pirate bugs
  7. Praying mantis
  8. Spiders


Randomly select 30 tomato plants and examine the leaves immediately below the topmost open flowers to look for eggs. When you find more than 5 eggs, start controlling the pest (AVRDC, 2000). When there is one fresh larval feeding damage on a green fruit from the randomly selected 40 plants and/or when 7 moths are trapped per week, a control measure is needed (Bessin, 2003). Remember, it only makes sense to control the larvae before they start to feed inside the fruits.

Management and cultural practices

  1. Remove the weeds. Plow the field to expose the pupae to predators and weather.
  2. Practice crop rotation. Do not plant other solanaceous crops after harvesting tomato. Never use tomato as a rotation crop for corn, sorghum, and cotton.
  3. Avoid planting tomato or pepper near corn or cotton to prevent heavy pest infestations.
