About - Adult thrips are slender and may appear as black or brown slivers on your leaves. They feed on your plants by using their mouths to draw fluid from plant cells. Thrips are skilled at hiding in crevices, which is why pesticides can be ineffective. To view the information sheet on this pest click here.

Monitoring - You may be able to see the adult thrips fly or jump if you disturb the area in which they are present. Yellow or blue sticky cards are attractive to thrip species and are an easy way to see if they are present. Plants will show bronze or silver coloured defects, and become brown and brittle. These bugs like flower buds and new growth best so watch these areas the most closely.

Treatment - The Orius insidiosus is the most popular treatment for thrips. It is a predatory insect that uses its long rostrum to pierce prey and drain the contents. Amblyseius cucumeris is a gluttonous predatory mite that feeds mostly on immature stages of thrips. Amblyseius swirskii is another predatory mite with a big appetite that will also dine on white fly and spider mites. Lastly, the Nematode Steinernema feltiae live in the soil and actively hunt for prey, entering natural openings and infecting the host.
