Product Description

Targeted Eretmocerus eremicus Whitefly Control with ERETforce™

ERETforce™ provides effective Eretmocerus eremicus whitefly control in greenhouse, indoor, and field crops. This beneficial parasitic wasp naturally controls multiple whitefly species, with a strong preference for tobacco whitefly (Bemisia tabaci) and silverleaf whitefly.

Eretmocerus eremicus parasitizes whitefly nymphs—especially the 2nd instar—by laying its eggs inside them. The developing wasp larva disrupts the whitefly’s lifecycle, stopping feeding and eventually killing the host. This biological control method is chemical-free, making it a smart addition to Integrated Pest Management (IPM) programs.

ERETforce™ is most effective in conditions between 68–77 °F with relative humidity below 70%. It’s safe to use around beneficial insects and leaves no harmful residue, making it an excellent tool for resistance management and sustainability-focused operations.

Release instructions for the use of Eretmocerus eremicus

Instructions For The Use Of Eretmocerus eremicus
Release these wasps immediately the day of receipt. To release, separate the individual cards at the perforations by gently folding them back and forth so as not to loosen too many of the lightly secured pupae (the yellow specks on the
cards).

Take special care not to touch the pupae, they are extremely delicate. Securely hang the cards, once separated, from the middle to upper branches of the plants in the area to be treated. Placement next to whitefly populations is advisable if the pest population is localized. If it is not, hang the cards evenly throughout the area, or next to the preferred host material of the pest if used preventively. Hang the cards in such a way that they will be sheltered from the sun’s rays and from watering, mist, irrigation, etc.

Leave the cards in place, undisturbed, for about 20 days to ensure thorough emergence.
Do not cold store!
