Amblyseius swirskii is a voracious predator of many different pests but it is best known for its ability to control both whitefly and thrips, along with broad mites. Only larval thrips can be consumed by swirskii, though, so this makes them most effective as prevention when thrips levels are still very low. Some of the thrips species they can help control include: Western Flower Thrips (Frankliniella occidentalis), European Flower Thrips (F. intonsa), Onion Thrips (Thrips tabaci), and Chili Thrips (Scirtothrips dorsalis).
As with all Amblyseius/Neoseiulus species, other arthropod pests may also be eaten in the absence of their preferred prey, along with pollen from flowering plants. This makes Amblyseius swirskii an ideal choice for thrips and broad mite prevention. The conditions for optimum performance are between 77 and 82°F with relative humidity around 70%. Note that those are the optimum conditions, and not a prerequisite for a successful program.
