This photo is an adult flower thrips. Note the heavy setae on the tip of this flower thrips abdomen. These don't occur on the abdomen of a Chilli thrips.

This series of photos shows the use of a paint palette used to sample for thrips. The foliage of the plant being sampled is "slapped" against white colored palette. The palette is then inverted to allow the trash to fall off making it easier to observe and collect the insects.  Thrips are then collect using a small paint brush and then placed in a tube containing (~70%) alcohol.

Orchid Thrips,

Chaetanaphothrips orchidii (Moutlon)

                 

This species of thrips looks very much like Chilli thrips. However, there is a "break" in the dark coloring of the wings.  This gives the Orchid thrips the appearance of having 2 dark spots on the front portion of the abdomen.


 DAMAGE PHOTOS

The following  photos demonstrate damage that is being attributed to the Chilli Thrips, Scirtothrips dorsalis Hood. This pest was found attacking roses in Palm Beach County.  Serious problems with thrips have also been noted in the Orlando area.  We know that the redbanded thrips, Selenothrips rubrocinctus (Giard), is also causing significant damage to Knock Out roses in the area (see Red Banded Thrips Link) but the adult redbanded thrips is black in color whereas the Chilli Thrips is much smaller and very light brown or straw colored.

This new pest has been found in 16 counties from Gainesville (Alachua County) to Key West (Monroe County).  It has been found in 62 retail nurseries and 1 wholesale nursery. Of the positive detections, 54 were from Rosa sp. (rose), 10 from Capsicum sp. (pepper) and 1 from Illicium sp. (anise). See the Regulatory Update file below. 

The presence of this pest was brought to our attention by William Schall, University of Florida, IFAS Extension from the Palm Beach County Office. The Department of Plant Industry (DPI, FDACS) is the responsible agency for  identifying the specimens and sending us the alert.  Click on the icon below to view the DPI pest alert.
