Eretmocerus hayati – Nature’s Smart Solution for Silverleaf Whitefly

Silverleaf Whitefly is one of the most destructive pests affecting vegetables, cotton, ornamentals and greenhouse crops. Heavy infestations weaken plants, spread plant viruses, reduce yields and often require repeated chemical spraying.

Eretmocerus hayati offers a smarter, sustainable solution.

This tiny beneficial wasp works continuously inside your crop by attacking whitefly in two different ways. Female wasps lay eggs beneath whitefly nymphs where developing larvae consume the pest from within. Adult wasps also feed directly on immature whiteflies, providing immediate suppression while establishing long-term biological control.

Unlike conventional insecticides that require repeated applications and may lead to resistance, Eretmocerus hayati establishes a living population that continues searching for whiteflies throughout the crop.

Perfect for Integrated Pest Management (IPM), this beneficial insect helps growers produce healthier crops while reducing chemical residues and protecting other beneficial insects.

Whether you grow tomatoes, cucumbers, capsicums, melons, cotton or ornamentals, Eretmocerus hayati provides environmentally responsible whitefly management that works naturally.


Key Benefits

✅ Targets Silverleaf Whitefly (Bemisia tabaci)

✅ Dual action predator and parasitoid

✅ Continues reproducing after release

✅ Excellent searching ability

✅ Effective even at low whitefly populations

✅ Compatible with IPM programs

✅ Reduces pesticide use

✅ Helps prevent insecticide resistance

✅ Safe for beneficial insects when compatible products are used

✅ Ideal for greenhouse and outdoor production


How It Works

  1. Female wasps locate Silverleaf Whitefly nymphs.
  2. Eggs are laid beneath the nymph.
  3. Larvae enter and consume the whitefly internally.
  4. Adult wasps emerge through a circular exit hole.
  5. Adults continue feeding on immature whiteflies.
  6. New generations develop naturally, providing ongoing suppression.
