This series of photos shows the use of a paint palette used to sample for thrips.

They attack all above-ground growth, but prefer young leaves, buds, and fruits. These insects are poor flyers but are easily carried by the wind. The chili thrips will attack the foliage and basically the entire host plant. Chilli thrips are extremely small and difficult to distinguish from other thrips species without the aid of a compound microscope. Or watch the 2015 CLUE webinar by Dr. Stephen Arthurs, a UF/IFAS entomologist “Sustainable Roses: Chilli Thrip Research”, at https://gardeningsolutions.

Immature chilli thrips are also pale in color and resemble the immatures of many other thrips species. ifas.ufl.edu/mastergardener/volunteers/education/webin ars2016.html. The adult chilli thrips is approximately 1⁄2 the length of the western flower thrip. Chilli thrips can cause serious damage to plants, as they have piercing mouthparts that extract the contents of epidermal cells, leading to necrosis of plant tissue. University of Florida research found that on susceptible rose varieties, cultural and biological control measures could not control chilli thrips; therefore, to control them requires spraying and/or drenching with a systemic insecticide rated for thrips. Entomologists have described approximately 6,000 species. Strong visual evidence of the presence of Chilli Thrips can be observed by dead tissue occurring within the vein structure of the upper developing foliage around the bud. Their reproduction and damage may also be slowed by spraying with a water wand as you would for spider mites, but remember that the greatest concentrations of chilli thrips will be near the top of the plant while spider mites proliferate from the ground up.

Due to its diverse vegetation and subtropical climate, Florida is extremely suitable for the establishment of invasive alien flora and fauna (Ferriter et al. These obser- vations that rose varieties vary in susceptibility to chilli thrips were confirmed by the small UF/IFAS research project for which our society provided supplemental funding in 2016. Never use a systemic pesticide with the same MOA more than twice in a row. Chilli thrips favor new growth. See the list at http://mrec.ifas.ufl.edu/ lso/thripslinks.htm#HOSTS. Second instar nymph 5.
