Product description

British Columbia


Eretmocerus eremicus is an invaluable asset when it comes to controlling whitefly populations in greenhouses. This small parasitoid wasp feeds on larvae, which allows for a significant reduction in populations quickly. Thanks to the large number of eggs that females lay and their impressive reproductive speed, they have an impressive parasitism rate (74%). Combined with Encarsia formosa, you get a powerful combination that helps eradicate whiteflies.

Targeted crops

  • Vegetable crops:
    • Cucumbers
    • Peppers
    • Tomatoes, etc
  • Small fruits :

Application Instructions

For optimum efficiency, the average greenhouse temperature over 24 hours should be at least 20°C (68°F). Eretmocerus eremicus remains active at temperatures above 30°C (86°F). To ensure a successful eradication of whiteflies, it is important to keep in mind that Eretmocerus eremicus pupae must not be touched and should only be released into areas out of direct sunlight. The release rate should vary between 1-10 per m² depending on the climate, crop grown and density levels of whiteflies. For maximal efficiency, three separate releases over weekly intervals are recommended when temperatures exceed 20°C (68°F). When greenhouse temperature rises above 30°C (86°F) activity remains viable within the environment.

Storage Instructions

For best performance, disperse Eretmocerus eremicus immediately upon receipt. If it cannot be dispersed immediately, it should be stored within 1-2 days of receipt, protected from light and at temperatures between 8-10°C (47-50°F).

These conditions are necessary to ensure its development and its egg production potential at ideal temperatures of 25 to 29°C.
