Details
Eretline biological control agent contains the hymenopterous parasitic wasp,Eretmocerus eremicus. It attacks whitefly by host feeding on younger larval stages and parasitizing the second larval stage of greenhouse whitefly,Trialeurodes vaporariorum, and silverleaf/sweetpotato whitefly,Bemisia tabaci.
Key Features
- Performs well in warmer climates and in fluctuating temperatures and is likely to last all season long.
- Available in innovative blister packs for improved emergence and establishment.
- Excellent host-finding behavior.
Main uses
- Greenhouse whitefly
- Sweet potato whitefly
How It Works
- Eretmocerus eremicusfemales search for second instar larvae ofBemisiaorTrialeurodes. Upon finding a suitable host, they lay an egg between the host and leaf surface. The resulting larva parasitizes the whitefly host larva.
- Host feeds and controls large numbers of whitefly larva.
- Prefers warm temperatures. Optimum temperature range is 25-29°C / 77-84°F.
- Eretline should be used whereverBemisiais present. Since it can also be used to control greenhouse whitefly, it is useful in mixed populations.
Available delivery systems
- Blister packs - containing 5,000 or 10,000 pupae in total, as 20 blisters each blister producing a minimum of 250 or 500 adult.Blister packs make product clearly visible and allow the grower to judge quality and emergence more easily.

Handling & Storage
- Use at low doses to prevent whitefly establishment.
- Use a selective insecticide to clean up existing populations.
- If there is a risk of virus transmission to plants from invadingBemisiaadults, it may be preferable to use an insecticide and follow up later with Eretline releases.
Instructions for Blister Pack use
- Open the box in the greenhouse.
- Remove sheet of blister packs from the envelope, and separate along perforations.
- Bend the card forward slightly at the top of the blister, and pull the tabup.
