Amblyseius andersoni

$140.00$670.00

Amblyseius andersoni is a predatory mite native to North America. They feed on and control all stages of phytophagous mites with all mobile life stages of A. andersoni acting as predators. A. andersoni are an excellent choice for pre-emergent control of pest infestations because of their varied diet and ability to survive cooler temperatures.

Target Prey: Broad Mites, Cyclamen Mites, Spider Mites (incl. Two-Spotted), Russet Mites

Key Features:

  • Sachet releases provide up to 6 weeks of control.
  • Lower active temperatures allow for earlier release.
  • Compatible with Phytoseiulus persimilis and Stethorus punctillum.
  • They will also feed on thrips*, pollen and honeydew.

Optimal Conditions: 68-100°F with higher relative humidity as temperatures rise. They are active down to 42°F, but A. andersoni will enter diapause at cooler temperatures or in <10-hour light periods.

Release Rates: Some crops, including tomatoes & other highly resinous crops, require higher release rates.

  • Mini-Sachets/Sachets on Sticks: Place one sachet or stick per propagation tray or plant. Repeat releases every 4 weeks through the growing season.
  • Sachet Strips: Place strips within crop canopy along rows to reduce labor costs. Six strips per case.
  • Loose Media Bags/Bottles: Release at a rate of 1 mite predator per square foot. Repeat releases periodically throughout the growing season.

 

This Product Controls These Pests or Diseases: Broad Mite (Polyphagotarsonemus latus), Cyclamen Mite (Phytonemus pallidus), Carmine Mite, Two-spotted Spider Mite (Tetranychus urticae), Red Spider Mite (Tetranychus cinnabarinus), Tomato Russet Mite (Aculops lysopersici), and Rust Mite (Eriophyidae).

A. andersoni should not be used to control a thrips infestation. Use A. andersoni with A. cucumeris or Minute Pirate Bugs if thrips numbers are high.

Description

A. andersoni are effective predators of broad mites, cyclamen mites, two-spotted spider mites and russet mites; however, they work best when introduced while pest numbers are low. Use the release information below to determine the best method for release. If you are a first time user of mite predators, please call us at 1-800-827-2847 (Arbico) and we can walk through release instructions with you.

Release Instructions By Product Type:

  • Sachets on Sticks: Place sticks in the growing medium at time of planting and upon transplanting into pots. Repeat ever 4 weeks. Once plants mature, use mini-sachets.
  • Mini-Sachets: Open the shipping box of the sachets in the crop. Separate sachets by tearing along perforations. Hang every 2 meters inside plant canopy where possible. Do not hang where sachets will be directly exposed to intense sunlight or near heating pipes.
  • Sachet Strips: Place within plant canopy along crop rows. Crop and floor must be dry during application. Strips can be attached to the irrigation boom. Do not separate sachets or hang on heating pipes.
  • 5 Liter Bag: Release during propagation. Apply evenly throughout the crop and try to apply to foliage, not to media. Avoid applying directly to flowers if application are made during flowering stages.

 

 

Environment: Suitable for outdoor and greenhouse growing environments.

Storage: Keep the product at around 50-59° F until ready to release, but do not refrigerate. Place out of direct sunlight. Use within 18 hours of receipt.

  • Amblyseius andersoni hatch at temperatures between 68° and 77°F. In cooler temperatures they will enter diapause to survive.
  • Working temperature range: 42-100°F
  • Relative Humidity: Higher humidity needed for environments with higher temperatures.

 

Viability Note: If you plan to check for viability, please do so upon receipt and prior to releasing the beneficial insects. Many predators and parasites are small and can be difficult to spot once released.
