Amblyseius swirskii are an excellent beneficial mite for preventative control of thrips, whitefly and various mite species. This predatory insect prefers warm, humid environments. Repeated releases of adults will be necessary in the presence of low temperatures. Amblyseius swirskii can consume about 10 thrips or whitefly larvae a day and up to about 20 whitefly eggs per day. In warm and humid environments they reproduce quickly, therefore they are an optimal choice for crops grown under protection in warm environments. Typically, they can be used until nighttime temperatures drop below 60F.
