Amblyseius swirskii
Description
Amblyseius swirskii is a very effective generalist predatory mite used to suppress immature thrips, two-spotted spider mites, cyclamen (or strawberry) mites (Phytonemus pallidus), broad mites (Polyphagotarsonemus latus), mites of the genus Schizotetranychus and whiteflies in ornamental, fruit and market garden crops.
Adults are pear-shaped, 0.5 mm long, with long legs. The eggs are round and transparent and measure 0.14 mm in diameter. These mites lay their eggs on leaf hairs (trichomes) and along the veins on the inner surface of leaves. The eggs hatch about 3 days later.
Like generalist insect predators A. Swirskii can maintain its population even when there are no more thrips on the plants and start working as soon as thrips reappear. A. swirskii is not susceptible to diapause it can be used throughout much of the season. A. Swirskii needs more heat than Neoseiulus cucumeris to complete its development. Used the predator mite when the temperature is above 25 °C (77 °F).
