Western flower thrips (Frankliniella occidentalis) has been assumed to be the only major thrips pest of greenhouse ornamentals for decades. As early as 2012, growers in Ontario, Canada began noticing sudden failures of biocontrol programs thrips which had previously been successful.  A survey conducted in 2015 in Southern Ontario indicated the presence of onion thrips (Thrips tabaci) as a pest of a wide variety of greenhouse ornamental crops.  This talk outlines the discovery, damage, and suspected range of onion thrips as a pest of greenhouse floriculture crops, as well as recommendations on control.
