Our Amblyseius andersoni sachets (Anso-Mite) are ideal for use against a range of insect pests. Amblyseius andersoni is a generalist predatory mite that that feeds on a variety of small insect pests which include eggs and larvae of Whitefly, young larvae of Thrips, Fuchsia Gall Mite, Rust mite, Spider Mites (pre-webbing) and Fruit Tree Red Spider Mite.
The full range of pests that Amblyseius andersoni has been proven to be effective against includes:
Amblyseius andersoni is a cold tolerant predator compared to other predatory mites, so can be applied effectively in cooler conditions.
The andersoni predators work by piercing the prey and sucking out their body contents. You will normally spot the andersoni on the lower surface of the leaves and they are very similar in appearance to other predatory mites
Amblyseius andersoni predators should be used as an early preventative treatment when pest levels are low. Introduce the andersoni before, or at early signs of pest infestation. The predators can be also be applied in the absence of a pest, as the predators can survive by feeding on pollen.
We do not recommend you use the andersoni against Spider Mites when there are high numbers of the pest, or webbing is present. Choose instead from one of our other predatory mites to tackle Spider Mites at this stage of the pest cycle. You can find our range of available Spider Mite predators by clicking here.
Amblyseius andersoni are active from 12-14℃ and above, with an optimum temperature being between 20-28℃. Amblyseius andersoni are sensitive to relative humidity below 65%.
We recommend the following application rate based on an average plant height of 1m:
- 1-2 sachets per plant
To maintain populations, introduce new sachets every 4 weeks.
Amblyseius andersoni sachets slowly release predatory mites onto plants for up to four weeks. There is also a food source of prey mites supplied within the sachet, which helps the production of more predators.
Simply hang the sachets in a sheltered spot on the plant, out of direct sunlight There is already a hole in the sachet for the predators to exit from, so the sachets do not need opening.
Do not apply the andersoni with Amblyseius swirskii, Amblyseius cucumeris or Amblyseius californicus predatory mites. The andersoni can, however, be used with other Thrip predators such as Mighty Mite, Hypoaspis miles, Orius laevigatus and Lacewing Larvae.
Full application instructions are provided on delivery.
Unfortunately due to the 4-week life cycle you cannot store the sachets for later use. Apply the sachets immediately on receipt.
Amblyseius andersoni is a living creature and can be affected by any chemical pesticides used within the previous few weeks. As a general guide, refrain from using Natural Pyrethrum or SB Plant Invigorator 2 days prior to use. Other chemical insecticides can have long lasting residues that could harm the andersoni, and other predatory mites, for much longer periods. Refrain from using these products, or check with Dragonfli for information on the effects of these products on predatory mites.
Just as you can be allergic to cats, pollen, and dust mites, it is also possible to be allergic to the natural substances in predatory mites, feeder mites, and supplementary feeding products. If you are particularly allergy prone and concerned about the potential effects of our mites please contact your local GP prior to purchase. Please note that allergic reactions to our mites are extremely rare.
