Amblyseius andersoni



Target Pests: broad mite (Polyphagotarsonemus latus), hemp russet mite (Aculops cannabicola),cyclamen mite (Phytonemus pallidus), two-spotted spider mite (Tetranychus urticae), red spider mite (Tetranychus cinnabarinus), tomato russet mite (Aculops lysopersici), rust mite(Eriophyidae)

Description: Amblyseius andersoni appear commonly in parts of  North America and Europe. They are generally located in areas with concentrations of grape and apple production, but can also be found in various soft fruits, peaches, and even certain conifers. The andersoni preys on multiple species of small arthropods and pollen.

The adult andersoni has a light beige pigment, and average in size a little less than 1 mm long. andersoni females can lay approximately 35 eggs throughout their lifetime. Initially the younger larvae will only have 6 legs. Upon entering its next 2 nymph stages; the andersoni will obtain a total of 8 legs

Life Cycle: Adult female andersoni will lay individual eggs on top of leaf hairs, which can hatch anywhere from 2-3 days. Once the andersoni reaches its larvae stage they will molt into protonymphs, and eventually become deutonymphs. The complete transformation from an egg to an adult ordinarily takes 8-11 days at 68-77°F (20-25°C). The healthy adults can live about 3 weeks. andersoni becomes ineffective at 35°F. 

From the andersoni's early larvae stage to Its full adult form, it will constantly be a predator. Commonly they will feed on anything from eggs, to juveniles and even adult spider mites. They also have the ability to feed on rust and russet mites (tiny, worm-like mites which can cause major damage to some crops).

As days become shorter and temperature decreases in the fall, the mites will undergo a period of suspended development in order to survive the winter conditions. They have been known to possibly become active again as early as January, but this will all be dependent on key factors such as an ideal climate and sufficient food available.

For Best Results: Try and apply andersoni early on during infestations when pest mite numbers are low. The predatory mites will then be able to focus on the smaller concentrations of mites and prevent them from growing larger and causing major damage. Late applications of andersoni can also be successful on specific crops, such as cucumbers and some hardy ornamentals.

 Keep the predatory mites in shade until they're ready to use, and distribute them as soon as conditions become viable. Keep the product at around 50-59° F. Do not refrigerate.

Introduction Rates

200 mini sachets with hooks attached (indoor use) - introduced at 2 meter spacing along the crop row. Apply to any convenient location on the plant, such as a leaf petiole, twig or small branch. Hang from crop wire or plant. Do not hang adjacent to heating pipes. Duration of sachet activity is 6 weeks, though longer-lasting control may be evident if the mites are establish in the crop. For trees use 1 sachet per tree.
