Thripex-Plus Predatory Mites – 100 & 500 Slow-Release Sachets for Thrips Control
Thripex-Plus provides biological thrips control using the beneficial predatory mite Neoseiulus cucumeris, previously known as Amblyseius cucumeris. These predators search plant foliage for young thrips larvae, helping manage pest populations as part of an Integrated Pest Management programme.
Available in 100-sachet and 500-sachet packs, Thripex-Plus provides a gradual introduction of beneficial mites over several weeks. Each sachet contains 1,000 predatory mites plus prey mites in a bran carrier, supporting predator breeding before they move onto surrounding plants.
Important: Do not use Thripex-Plus on tomato crops. Check crop suitability and follow the application guidance supplied with your order.
Key Features & Benefits
- Biological thrips control: Contains live Neoseiulus cucumeris predatory mites.
- Two pack sizes: Choose 100 or 500 slow-release sachets.
- Targets young larvae: Helps suppress thrips populations during their early development.
- Gradual predator release: Beneficial mites breed within the sachets and disperse over several weeks.
- Preventative application: Suitable for introduction before pest populations become established.
- Convenient hanging format: Distribute sachets throughout suitable crops without mixing or spraying.
Available Thripex-Plus Pack Sizes
| Product Option | Pack Contents | Contents Per Sachet |
|---|---|---|
| Thripex-Plus 100 Sachets | 100 slow-release sachets | 1,000 predatory mites plus prey mites |
| Thripex-Plus 500 Sachets | 500 slow-release sachets | 1,000 predatory mites plus prey mites |
Both options contain the same beneficial mite species and use the same release method. Select your pack quantity according to the recommended application rate and the area requiring treatment.
Targeted Control of Young Thrips Larvae
Neoseiulus cucumeris feeds primarily on young thrips larvae, including those of western flower thrips and onion thrips. First-stage larvae are easier for these predators to overcome than larger larvae.
These sachets should not be relied upon to control adult thrips. Where an infestation is already established, seek advice on a coordinated programme addressing the different pest stages.
The predators can also feed on pollen and alternative prey when available, supporting their establishment before thrips numbers increase.
Slow-Release Sachets for Ongoing Protection
Each sachet acts as a small breeding environment containing predators, food and carrier material. The mites reproduce inside before emerging through the provided opening and moving onto the crop.
Unlike loose predatory mite products that are distributed directly onto foliage, Thripex-Plus introduces mites gradually. Leave the sachets intact so this release system can work as intended.
How to Apply Thripex-Plus
- Plan the release: Select a rate appropriate to your crop, climate and pest pressure.
- Handle gently: Hold sachets by the cardboard strip at the top rather than squeezing the contents.
- Distribute evenly: Hang sachets throughout the crop in sheltered positions away from direct sunlight.
- Leave intact: Sachets already have an exit opening; do not cut them open.
- Monitor regularly: Check pest activity and follow the recommended repeat-release programme.
Application Rate
Koppert's general guidance is at least 4,000 sachets per hectare, evenly distributed. Repeat introduction after four weeks if the pest is not controlled.
Obtain crop-specific advice before ordering. This general rate is not a guaranteed coverage figure for every situation.
Suitable Growing Conditions
Neoseiulus cucumeris is most effective between 15°C and 25°C. Koppert advises that it is not effective above 30°C and is sensitive to relative humidity below 70%.
Check conditions within the foliage before release. Any environmental adjustments must also remain suitable for the crop.
Compatibility with Other Treatments
Thripex-Plus can be combined with suitable Orius species. Koppert advises against combining it with the generalist predatory mites Amblyseius swirskii, Amblydromalus limonicus, Transeius montdorensis or Amblyseius andersoni.
Check pesticide compatibility and residual effects before introducing beneficial mites or applying further crop protection treatments.
Storage & Handling
Apply promptly after delivery. If storage is unavoidable, keep for no more than 1–2 days at 10–15°C, in darkness with adequate ventilation to prevent carbon dioxide accumulation.
Follow the product-specific instructions supplied with your order.
