Application Instructions
Before introduction, very gently shake the tube to homogenize the content inside and spread the mites all over the tube. Then sprinkle the content on the leaves or where you see infestation. The application rate for Amblyseius andersoni varies based on factors like climate, crop type, and pest population density, and should be tailored to the specific conditions. Preventive introductions are recommended shortly after planting. Standard release rates range between 50 and 250 mites per m² per application. Releasing should be done at least three times, with weekly intervals, or until pest control is successfully achieved.
Storage Instructions
It is always recommended to use A. andersoni upon receipt to ensure maximum efficacy. If storage is needed, you can keep them at 8°C–10°C for a maximum of 1 to 2 days. Avoid freezing and prolonged exposure to temperatures above 25°C.
Description
Amblyseius andersoni is a generalist predatory mite from the Phytoseiidae family, measuring approximately 0.5 mm in length and varying in color from beige to light brown. This versatile predator adapts well to a wide range of environments and can survive on multiple food sources, making it an excellent biological control agent for various crops. It thrives on plants with smooth leaves but tends to avoid those with high densities of glandular trichomes, as these can hinder its effectiveness. Tomatoes for example are not the best host as they are hairy.
