Currently two Beauveria-based products, BotaniGard® (Mycotech Corp.) and Naturalis®-O (Troy Biosciences), are available for thrips management in greenhouses. Also Isolates of Verticillium lecanii have been available commercially for many years in Europe for control of thrips and other glasshouse pests (Ravensberg et al. 1990, van der Schaaf et al. 1991, Helyer et al. 1992). I think these articles can be useful for you:
