  1. Education and Training to Increase Adoption of IPM for Western Flower Thrips Jennifer L. Gillett-Kaufman, Norman C. Leppla, Amanda C. Hodges, and Joyce L. Merritt Entomology and Nematology, University of Florida, IFAS, IPM Florida, Southern Plant Diagnostic Network

  2. Education and Training to Increase Adoption of IPM for Western Flower Thrips • Problem overview • Completed education activities • Upcoming programs and educational products • Overall expected program outcome

  3. Problem Overview • Proper species level identification can be difficult- small size (adult is <1/10 in.)- hand lens- dissecting scope- compound microscope- sample to Distance Diagnostic and Identification System (DDIS)- sampling either with aspirator or white paint board Photo credit: Lance Osborne

  4. Problem Overview • Confusion with other species Photo credits:Joe Funderburk Adult female Larva Western Flower Thrips – Frankliniella occidentalis

  7. Host Damage • Feeding damage can vary depending on the plant part - Damage on leaves and petals by WFT Photo credits: NCSU

  8. Host Damage • Virus vectors for tomato spotted wilt virus (TSWV) and impatiens necrotic spot virus (INSV)- Western flower thrips, Florida flower thrips, tobacco thrips- Symptoms vary depending on host species, cultivar, developmental stage, and environmental conditions Photo credit: David Schuster Photo credit: Hank Dankers Western flower thrips Florida flower thrips

  9. Resistance and IPM • Pesticide resistance – WFT resistant to almost all insecticides; susceptible to spinosyns • Integrated Pest Management can be difficult with multiple pests in various crop systems- Pepper weevil (Anthonomus eugenii)- Silverleaf whitefly (Bemisia tabaci)- Thrips species Photo credit: Jeff Brushwein Pepper weevil

  12. Education and Training • Grower’s IPM Guide for Florida Tomato and Pepper Production - available on IPM Florida website • Thrips on IPM Florida website http://ipm.ifas.ufl.edu/agriculture/vegetables/thrips/index.shtml

  13. Thrips Pest Management Webpage • Thrips 101 • Scouting • Identification of thrips • Identification of natural enemies of thrips • General IPM practices that reduce thrips populations • Thrips management in specific crops

  14. Thrips Website • Challenges of thrips management • Tracking thrips resistance to insecticides • Specialists working group • Education and training activities • Grower’s IPM Guide for Florida Tomato and Pepper Production • Links

  15. Distance Diagnostic and Identification System (DDIS) Sample submission system http://ddis.ifas.ufl.edu/ddisx/home.jsp • Take an photograph of the sample • Login to DDIS • Upload the image to DDIS website • Receive assistance with identification
